Borrowdale probably contains
a greater extent of native woodland
than any other of the Lakeland valleys, and from the road it can
appear that almost the whole dale is forest clad on its lower slopes
- an impressive effect. Most of the woods are of the hanging type,
on steep slopes ranging from c. 75 to 370 m, and covering all
aspects, but The Ings and Castle Head Wood lie on the floor of the
valley: the latter on a small hill. The parent rock is almost
entirely the Borrowdale Volcanic Series, which generally gives
acidic soils, but contains calcite bearing beds (and fault shatter
belts) in many places, as at Lodore and in Seatoller Wood. The
slopes within most woods are variably covered with block scree.
These are composed of rocks of all sizes. Many woods have outcrops
which vary in size from small faces to high cliffs around Lodore.
These woods lie within a very sharp rainfall gradient ranging from
about 178 cm annually at Castle Head Wood to about 318 cm at
Seathwaite.
There are fine stands of
high forest sessile oakwood in Great Wood,
Johnny's Wood and Seatoller Wood, and smaller coppice in Troutdale.
A shrub layer is generally absent and there are merely scattered
individuals of birch, holly and rowan. Ash-hazel wood occurs in all
sites except The Ings, but forms a large part of Seatoller Wood and
its juxtaposition here with sessile oakwood illustrates the same
kind of edaphic separation of woodland types as that found in the
lowland situation with slate and limestone in Roudsea Wood. The
ashwood contains a good deal of wych elm, and there is usually an
understorey of hazel, plus a greater variety of shrubs such as
Primus padus, P. spinosa, Crataegus monogyna and Rubus fruticosus.
The respective field communities are of Deschampsia flexuosa-
Anthoxanthum odora-tum, with sparse bilberry and much bracken on
leached brown earths under oak, and Brachypodium syhaticum-Geranium
robertianum with numerous other basiphilous herbs on base-rich loams
under ash-hazel. Rare herbs include Festuca altissima at Lodore and
Great Wood, Impatiens noli-tangere in Great Wood and Circaea alpina
in several localities; the last two species have their British
headquarters in Lakeland.
Castle Head Wood differs
from the others in a number of respects. It
is well-developed sessile oak over hazel woodland surrounded by
farmland and not open to the upland fell. This has reduced grazing
pressure, which in turn has enabled some natural regeneration to
take place and accounts for the relatively strong development of
field and shrub layers.
By the shore of Derwentwater
near Lodore, a fringe of alder, willow,
reed and sedge completes the ecological zona-tion of the catena from
the top of the hanging oakwoods to the lake shore. Alder woodland
near the lake is an important feature of Great Wood and is
exceptionally well-developed in The Ings. This site, although small,
is ungrazed, and the good field layer varies according to the
mineral/humus component of the substratum which may depend on
variations in silting from the inflowing stream.
Fern communities are well
developed, especially on block scree and
include Dryopteris filix-mas, D. dilatata, Athyrium filix-femina,
Thelypteris oreopteris, T. phegopteris, T. dryopteris and Blechnum
spicant. The rare Asplenium septentrionale grows on rocks in one
place. There is a general carpet of bryophytes composed of the
common species appropriate to oak and ash-hazel woods, but the most
important feature is the strong representation of the Atlantic
element. These woods, including the famous cascade ravine of Lodore
Falls, together constitute the most important locality in England
for Atlantic bryophytes and in richness they rival those of north
Wales and the western Highlands. The Hymenophyllum wilsonii-Scapania
gracilis-Plagiochila spinulosa community on blocks is well
developed, and there is local abundance of mosses such as Hylocomium
umbratum, Hypnum callichroum, Bartramia halleriana and the northern
Ptilium crista-castrensis, and Sematophyllum novae-caesareae. The
notable hepatics include Radula valuta, R. aquilegia, Jubula
hutchinsiae, Colura calyptrifolia, Plagiochila tridenticulata,
Frullania germana, F. microphylla, Marchesinia mackaii, Adelanthus
decipiens, Sphenolobus helleranus and Jamesoniella autumnalis.
Borrowdale appears to be especially rich in moisture-loving species
not only because of its western position and heavy rainfall, but
also because of the apparent historical continuity of woodland cover
in places. Seatoller Wood faces south-east and it is difficult to
account for the abundance of moisture-loving bryophytes, including
several species with very limited powers of spread, except in terms
of continuous Post-glacial woody cover.
The Borrowdale Woods are
equally important for oceanic lichens; the
main interest lies in the presence of a corticolous association,
characterised by the co-dominant Parmelia laevigata and P.
taylorensis. A total of 111 species have been recorded from
Seatoller Wood, which include species such as Bacidia affinis, B.
isidiacea, Lecides berengeriana, Lopadium pezizoideum, Micarea
violacea and P. plumbea which are all very rare in Britain.
Great Wood is one of the
best localities in England for arboreal
lichens, including large foliose species such as Lobaria pulmonaria,
L. laete-virens, Sticta sylvatica and S. limbata.
The woods nearer the dale
head were once, and perhaps still are, the
haunt of the pine marten, and they have the red squirrel, now
reduced and local. The more notable breeding birds include common
buzzard, pied flycatcher, wood warbler and grey wagtail.
These Borrowdale Woods
are a key station in the internationally
important series of western hill woodlands with rich Atlantic
floras, and as a group they are clearly in the first echelon of
grade i sites.
W.I34. KESKADALE
AND BIRKRIGG OAKS, CUMBERLAND
NY 208195, NY 215205 and
NY 220205. 9 ha
Grade i
These two small areas of
woodland are situated on the southern
slopes of two adjacent mountain ridges. The Birkrigg area extends
from 350 to 430 m and the Keskadale Oaks from 300 to 460 m. A
shallow acidic soil is formed by the weathering of the shaly rock of
the Skiddaw Slate Group.
These woods are almost
completely of sessile oak with a few
scattered rowans. The oak in both areas is low and springs from
multiple stems and at least in the Keskadale Wood coppicing has
probably taken place. However, coppicing is not the sole reason for
the growth form, as factors such as fire, grazing, disease and
bruising of the tree base all contribute. The woods apparently
differ in that there is much more active scree in and near the
Birkrigg Oaks whilst the Keskadale Oaks have a more stable as well
as more grazed appearance. Both woodlands are wind-pruned, with
stature of the trees decreasing to that of scrub at the upper edges,
especially in the Keskadale wood.
The field layers in both
woods are similar and open as the thin fine
soil layer tends to get broken and eroded. Bilberry is dominant
together with bracken and heather, the heather becoming dominant
where the canopy is open. Other species common in the field layer
include Blechnum spicant, Des-champsia flexuosa, Potentilla erecta,
Agrostis canina, Galium saxatile, and Oxalis acetosella. Bryophytes
are abundant and Dicranum scoparium, Hypnum cupressiforme and
Pleurozium schreberi occur frequently. Epiphytic bryophytes and
lichens clothe most of the trunks, with Ulota sp. common on the
upper twigs.
These woodlands represent
relict fragments of high-level sessile
oakwood and may be near the altitudinal limit for oak woodland in
western Britain.

W.I35- ORTON
MOSS, CUMBERLAND
NY 3454.
50 ha
Grade i
These very mixed woods
are developed partly on a former peat moss,
possibly of the raised mire type but probably grading into valley
mire. Areas of Scots pine are periodically cut and replanted, but
this tree regenerates very freely naturally. Pinewood has a typical
bilberry-moss community, but Dryopteris dilatata is locally
abundant. The pine stand felled around 1958 had a good colony of
Goody era repens, but this has not been found in other areas of
pine. A good deal of sessile oak is scattered through the woods,
usually mixed with Scots pine and birch, and birch also forms pure
stands of different ages with some trees reaching a large size.
There is also much rowan, hazel and holly, and more locally, alder
buckthorn. In one place, old peat diggings in the original
ombrotrophic peat carry an acidophilous mire vegetation with a
Sphagnum carpet and Myrica gale, Andromeda polifolia, Oxycoccus
palustris, Carex curta and Osmunda regalis.
Heathery clearings on dried
out peat have gradually developed a
subspontaneous growth of Scots pine and birch during recent years.
The former valley mire which floods during winter has a poor-fen
with a great deal of Carex rostrata, Calamagrostis epigejos and
Dryopteris spinulosa. In this part of the woods there is a much
mixed willow (mainly Salix «'»eraz)-alder-birch swamp woodland with
a Sphagnum recurvum-S. auriculatum floor. Pyrola minor is frequent
in these damper areas. While the soils are mostly acidic, a few
areas of more basic loam occur on which grow herbs such as Geum
rivale, Circaea lutetiana, and Sanicula europaea. Ivy and polypody
commonly occur as members of the field community on dry acidic soils.
Orton Moss is especially
interesting for the old hay meadows which
occur around the edges, especially on the south and west sides.
These unploughed and herb-rich meadows grade into the woodland, and,
because of the abundance of Succisa pratensis, the larval food
plant, are celebrated as the haunt of the marsh fritillary
Euphydryas aurinia. The whole area is extremely rich entomologically
and rates highly on this account. Ornithologically, it is important
as the breeding haunt of at least three pairs of sparrowhawks, and
it also contains a good range of other woodland bird species.
W.I36. WHITBARROW
AND WITHERSLACK WOODS, WESTMORLAND
so 4487.
160 ha
Grade i
The area contains two main
blocks of woodland. On the west side in a
slight valley, below the west-facing Carboniferous Limestone scarp
of Whitbarrow Scar (see L.I36), is a large stand of high forest,
grading into scrub as the slope steepens. On the eastern, dip slope
of Whitbarrow Scar, is a much more heterogeneous woodland with a
mosaic of coppice, scrub and planted conifers on discontinuous
limestone pavement.
The high forest, extending
from Pool Bank to Wither-slack Hall,
consists of a mixed sessile oak-ash wood, becoming purer oakwood
near the road, where the rock changes to Silurian slate. This wood
is important for its relatively large area of tall, well-grown oak,
a relatively rare feature in this district where so much of the
woodland has been coppiced. Although the wood is ungrazed, the field
layer is not species rich, and the influence of the limestone is not
particularly obvious until the slope of the Scar is reached. Rubus
fruticosus is dominant locally, though R. saxatilis is also abundant
near the road. There is local abundance of Mercurialis perennis and
Brachypodium sylvaticum but the herb flora is not large. Thelypteris
phegopteris is locally luxuriant. Birch is quite abundant, there are
patches of hazel thicket, and dense ash regeneration occurs in
places. Wych elm is frequent and small-leaved lime occurs here in
one of its northernmost localities.
On the slope falling from
Whitbarrow Scar there is a belt of pure
yew- wood and above this a lower growth of oak, ash and hazel,
passing on the scarp to scrub with juniper, yew, hazel, birch,
buckthorn and Sorbus lancastriensis. There are old records of Daphne
mezereum.
To the west of the road
there is a change to ashwood on and beneath
a second, smaller, and east-facing limestone scarp. The flora here
is richer than that of the oakwood, with most of the typical ashwood
species, and more local plants such as Ophrys insectifera, and the
shady rocks have an abundance of calcicolous bryophytes.
The native woodland on
the dip slope is mainly a scrubby ash-hazel
growth, grading into sessile oak locally, and the field layer
contains much Brachypodium sylvaticum and Sesleria caerulea, with
Carex ornithopoda and Melica nutans quite plentiful. The grikes have
Phyllitis and Dryopteris villarii, and Epipactis atrorubens occurs
in more open places, while interesting bryophytes include the
northern Rhytidium rugosum and the southern Atlantic Marchesinia
mackaii. There was formerly a native colony of Allium schoenoprasum
near Rus Mickle. Basiphilous woodland herbs are well represented and
there are all transitions to open pavement with its characteristic
flora (see under Lowland Grasslands, Heaths and Scrub). Despite
conifer planting, which clearly causes surface acidification and
impoverishment of this interesting flora, it is apparent that there
will always be a patchy occurrence of native scrub and associated
field/ ground communities on the rockier, unplantable ground, and
this eastern area is included in this important grade i site for its
great botanical interest.
W.I37- BIRK
FELL, WESTMORLAND
NY 4018.
ioo ha
Grade i
This is the most extensive
continuous stand of juniper in Lakeland,
and equals or exceeds that of Upper Teesdale in size. Unlike juniper
scrub considered under the lowland calcareous habitats it grows on
leached skeletal brown earths over Borrowdale Volcanic rocks and has
few basi-philous associates, though there are some patches of richer
soil locally. The relationship with woodland is fairly close and
this juniper scrub passes below into a stand of birch-wood which
occupies the base of the slope. Towards the edges of the wood, the
junipers are smaller, probably as a result of grazing by sheep and
red deer. The individual trees of the Tynron Juniper Wood have a
generally greater stature, but Tynron Wood covers a much smaller
area than the Birk Fell juniper wood. In the Highlands juniper
scrubs mostly occur as the shrub layer of pine and birch woods, and
stands on open moorland tend to occupy damp hollows rather than dry
slopes as in Lakeland.
The birchwood may be a
serai derivative of sessile oak-wood, for it
occupies the habitat held by the latter elsewhere in the Ullswater
valley. The field layer of this wood is virtually identical with
that of the other Lakeland oakwoods on acidic soils, and the
bryophyte communities are also typical, but with poor representation
of Atlantic species. The filmy fern Hymenophyllum wilsonii occurs
sparingly.
W.I38. HELBECK
AND SWINDALE WOODS, WESTMORLAND
NY 7816-8016.
135 ha
Grade i*
This is the northernmost
of the internationally important series of
ashwoods on the Carboniferous Limestone and lies on the Eden valley
scarp slope of the Westmorland Pennines, above Brough. Helbeck Wood
is on the frontal slope which rises in ridges and tiers of limestone
scar towards Little Fell at the southern end of the Cross Fell
range, while Swindale is the adjoining deep and cliff-lined valley
cutting this slope at the eastern end. The ashwood is fairly pure in
places, but there is locally a good deal of wych elm, and towards
the edges more open birchwood with hawthorn takes over. Oak is
scattered and there are varying amounts of hazel, aspen, rowan,
holly, gean and bird-cherry. Southern species of tall shrubs are
represented: Crataegus oxyacanthoides occurs sparingly here, its
northern limit; buckthorn is recorded; and there is a small amount
of spindle. The northern willow Salix phylicifolia occurs alongside
Swindale Beck. Non-native species such as larch, sycamore and beech
are present, but in rather small quantity, and they thus add to the
diversity of the woods rather than detract from their quality.
Parts of the woods are
ungrazed or lightly grazed, and there is a
rich development of herbaceous communities, with the usual Allium
ursinum-Mercurialis perennis types conspicuous, but also a variety
of others associated with more open conditions, especially on screes
and outcrops. The more local herbs include Myosotis sylvatica, Cepha-
lanthera longifolia, Convallaria majalis, Vicia sylvatica, Paris
quadrifolia, Aquilegia vulgaris, Campanula latifolia, Epipactis
helleborine, Rubus saxatilis, Geranium lucidum, Cirsium
heterophyllum and Polygonatum officinale. On steep rocks are
Hippocrepis comosa and Car ex ornithopoda. The two rare horsetails
Equisetum pratense and E. hyemale grow within the site.
Other field communities
include the grassy type, dominated by
Brachypodium sylvaticum and there are also transitions to the
Sesleria albicans and Festuca grasslands of the open hillside. In
places there is dominance of bluebell with bracken, especially
around the lower edges of Swindale. Within Helbeck Wood is a small
tarn, with fringing calcareous marsh of sedges and 'brown mosses',
with an abundance of Primula farinosa and Valeriana dioica.
Altogether, the diversity of habitat and floristics, and the
gradation into other important upland communities, make this a most
important site. It is contiguous with the Appleby Fells grade i
upland site (U.22).
W.I39- ROUDSEA WOOD,
LANCASHIRE
503382.
n8ha
Grade i
This exceptionally diverse
woodland lies almost at sea-level (0-20
m) on the east side of the Leven Estuary at the head of Morecambe
Bay. It merges to the east into the northern end of an estuarine
raised mire complex (the Holker Mosses) and to the west and north
into salt marsh flanking the Leven Estuary. The wood itself covers
two ridges of contrasting
geology separated by a
shallow valley which contains a valley mire
and small tarn.
The east ridge is of Carboniferous
Limestone and carries an ash-oak
wood with some small-leaved lime, gean and birch. The oak is mainly
pedunculate but sessile and intermediate forms occur. Characteristic
limestone shrubs include purging buckthorn, spindle, blackthorn and
guelder rose, and there are also hazel, holly and hawthorn. The
field layer of this ash-oak wood is markedly calcicolous, with a
general predominance of Brachypodium sylvaticum and Mercurialis
perennis, local abundance of Convallaria majalis, and a wide variety
of species. The more local herbs include Allium scorodoprasum,
Aquilegia vulgaris, Anacamptis pyramidalis, Brachypodium pinnatum,
Campanula latifolia, Carex digitata, Hypericum montanum, Inula
conyza, Lathraea squamaria, Lithospermum officinale, Neottia nidus-
avis, Ophrys insectifera, Ornithogalum umbellatum, Rubus saxatilis
and Sesleria albicans.
The west ridge is composed
of greywackes of the Ban-nisdale Slate
Series, with small areas of slate, and carries a contrasting sessile
oakwood with birch and some rowan and hazel. The field layer is
acidophilous, with dominance of Deschampsia flexuosa and Pteridium
aquilinum, or Molinia caerulea where there is an overlying peaty
alluvium.
The valley mire between
the ridges has a fairly eutrophic fen
vegetation, with Phragmites communis, Carex paniculata, C.
vesicaria, C. diandra, C. disticha, C. pseudocyperus, Juncus
subnodulosus, Calamagrostris canescens, Thalictrum fiavum,
Thelypteris palustris, Lycopus europaeus, Lythrum salicaria and
Lysimachia vulgaris. The tarn has species such as Baldellia
ranunculoides and Alisma plantago- aquatica. There is a scattered
growth of birch and alder on this wet ground. The greatest rarity of
Roudsea Wood, Carex flava (here in its only known British station),
occurs on the transition from dry limestone soils to peat, and
flourishes along the rides in this habitat.
Where the limestone ridge
passes into the raised mire system, there
is a change to birchwood over peat, with rowan and some Scots pine.
Where the canopy is open, there is dominance of bracken, but with
deeper shade this is replaced by bilberry. Alder buckthorn is a
conspicuous shrub in this transitional woodland. There is then a
change to the open mire surface, somewhat dried by cutting, draining
and burning, but still with characteristic plants such as Andromeda
polifolia, Narthecium ossifragum and Drosera rotundifolia. The
larger area of the adjoining Deer Dike and Stribers Mosses are a
grade i peatland site (P.4y), and form with Roudsea Wood a single
composite grade i site.
On the western and northern
side there is a transition from oakwood
through alderwood to estuarine salt marsh, a sequence seen in few
other places, though the oak is on higher rocky bluffs and is not a
serai development from salt marsh. The brackish transition zone is
marked by the presence of such plants as Carex distans, C. extensa,
C. otrubae, Samolus valerandi, Oenanthe lachenalii, Centaurium
littorale and Scirpus maritimus.
This site contains an unusual
range of habitats, and the flora of
the Roudsea Wood site contains at least 340 vascular 90 Woodlands
species. The woodland and
the adjoining mosses are also very rich in
Lepidoptera, and this is a station for the rare white-marked moth
Cerastis leucographa.
W.I40. GAIT
BARROWS, LANCASHIRE
so 4877.
31 ha
Grade i
The most important feature
of this site is the massive central
exposure of Carboniferous Limestone pavement, which is probably the
finest example in Britain of this extremely local habitat. The
vegetation of the pavement is described under lowland grasslands
(L.I34). There is a patchy distribution on the pavement of a tall
scrub with yew, hazel, juniper and young ash, and this has
associated shrubs such as purging buckthorn, spindle, dogwood,
privet, holly, small-leaved lime and Sorbus lancastriensis. This
type of scrub grades into taller woodland on more broken and
dissected pavement around the edges of the central mass, and there
is a general increase in stature of species such as ash and hazel on
deeper soils, where pedunculate oak also appears. This rather low
and open type of woodland has a rich limestone flora, with species
such as Convallaria majalis, Epipactis atrorubens, Atropa
belladonna, Hypericum montanum, Rubus saxatilis, Carex digitata,
Polygonatum odoratum and Melica nutans.
The pavement woodland passes
into a broad peripheral zone of taller
forest, though this varies in height and structure according to past
differences in management. In general, there is a dense coppice of
hazel, with standards of pedunculate oak, ash and sycamore. There
are also thickets of silver birch, and hornbeam and beech occur
locally, though both were probably introduced. The drift-derived
soils in this part of the wood vary from basic to moderately acidic,
and there is a lesser abundance of markedly calci-colous species
than in the limestone woodland. Bramble is widespread throughout the
coppice, and the field layer characteristically has Mercurialis
perennis, Endymion non-scriptus, Brachypodium sylvaticum, Primula
vulgaris, Sani-cula europaea, Circaea lutetiana and Viola riviniana.

WOODS, LANCASHIRE
so 6066.
35 ha
Grade i
This has been chosen as
an example of a northern mixed deciduous
woodland, and lies mainly on the east side of a deep glen draining
the northern side of the Bowland Fells. It lies on Carboniferous
shales and sandstones which give a range of soils from highly acidic
to strongly basic, and it is ungrazed. The most acidic brown earths
have typical sessile oakwood with Vaccinium myrtillus, Luzula
sylvatica and heath mosses. This grades into a mixed oak-birch wood
on slightly less acidic soils, and the field layer here is of Holcus
mollis and Endymion non-scriptus, with Stettaria holostea, Athyrium
filix-femina and Pteridium aquilinum. On wetter ground this type
changes to alder-birch wood, with Deschampsia cespitosa, Carex
remota, C. laevigata, C. sylvatica, Dryopteris spinulosa, D.
austriaca and Ranunculus repens. On the most basic soils there is a
mixed ash-oak-wych elm-hazel wood, with grass-herb communities of
the Brachypodium sylvaticum-Deschampsia cespitosa and Mer-
curialis perennis-Allium
ursinum type. Species of particular
interest include Stellaria nemorum, Carex pendula, Festuca
altissima, Phyllitis scolopendrium, Polystichum setiferum and P.
lobatum.
Although this is a woodland
developed on the steep sides of a glen,
it extends over more level ground on top of the east bank, and
covers a larger area than many gorge woods.

(b) Ling Gill SD 8078.
5 ha
These sites are regarded
as fragments of a once more extensive
subalpine ashwood covering much of the lower slopes of the Craven
Pennines and have survived by virtue of physical features; a
limestone pavement in the case of Colt Park and a steep-sided ravine
at Ling Gill, both of which afford protection from grazing. Both
woods are on Carboniferous Limestone; Colt Park is developed over a
pavement of limestone at about 340 m whilst Ling Gill is cut into
the upper part of the Great Scar limestone, at a similar elevation,
3 km to the north-east.
The tree layer in both
woodlands is composed mainly of rather open
and somewhat stunted ash. In Ling Gill the ash tends to be more
abundant on the crags and gill sides. In both woodlands a shrub
layer is present and contains hazel, hawthorn, bird-cherry and
rowan. Wych elm, birch and (in Ling Gill) aspen are also to be found
scattered throughout the canopy in places. Both areas have a rich
flora as a result of the calcareous substratum and lack of grazing.
Tall-herb communities are well developed and contain Trollius
europaeus, Geranium sylvaticum, Cirsium heterophyllum, Actaea
spicata, Crepis paludosa, C. mollis, Geum rivale, Angelica
sylvestris, Campanula latifolia and Paris quadrifolia. Gagea lutea
is less frequent. Submontane plants include Potentilla crantzii,
Galium boreale and Asplenium viride. In Ling Gill podsolic soils
above the rocky ravine slopes have an acidiphilous field layer with
Pteridium aquilinum, Molinia caerulea, Potentilla erecta and Galium
hercynicum.
The moist atmosphere and
shade of Ling Gill ravine and the grikes at
Colt Park have led to the occurrence of a rich bryophyte flora on
the limestone.

W.I43- CONISTONE
OLD PASTURE AND BASTOW WOOD, YORKSHIRE
SD 9867.
380 ha
Grade i
The site occupies part
of the Carboniferous Limestone escarpment on
the eastern side of upper Wharfedale. Great Scar limestone, divided
into two main blocks by a narrow gorge, outcrops as pavement, scar
and associated scree. Much of the soil is thin humus-carbonate
occurring in patches on the exposed limestone, but on the valley
sides and in depressions a deeper clay has developed, and in some
places acid, sandy loam. The more southerly of the blocks is wooded;
closed woodland mainly of ash, wych elm, and hazel with calcicolous
shrubs such as privet, buckthorn, and whitebeam, considerably
invaded by sycamore, characterises Grass Wood, while in the
contiguous Bastow Wood birch is predominant over much of the area
and forms an open canopy. This difference is probably related to
site history, in addition to somewhat greater elevation, for Bastow
Wood overlies a Celtic field system, and the contrast is now being
accentuated by re- forestation of Grass Wood, mostly on a shelter
wood system, but locally by clear felling and replanting with
conifers. Dib Scar, descending steeply into the gorge drained by Dib
Beck, forms the northern limit of this block, beyond which rises the
complementary limestone grassland and pavement of Conistone Old
Pasture, characterised by typical close-cropped species- rich swards
and a grike flora. Ecologically this site belongs partly with the
lowland calcareous grasslands, and gives an interesting comparison
with the more distinctly montane limestone communities in Cowside
valley and the higher slopes of Malham-Arncliffe (U.24).
The main feature of interest
is the herbaceous flora which is
outstandingly rich. The woods of the area are known as a locality
for the very rare Cypripedium calceolus, which has been reduced
almost to extinction by plant collectors. Herbs still present
include Polemonium caeruleum, Thalictmm minus, Geranium sanguineum,
Polygonatum odoratum, Paris quadrifolia, and Origanum vulgare. More
open ground in the area has Draba incana, Arabis hirsuta, Polygala
amara, Saxifraga hypnoides, and Sedum telephium, while flushes and
damper pastures have an abundance of Primula farinosa and Parnassia
palustris. The afforestation programme may ultimately reduce the
variety to some extent, but most species and the general richness of
the habitat are expected to survive.

The east side of the valley
has been partly felled and replanted but
it still shows a fine gradation from alder in the valley bottom
through ash-wych elm woodland with a basiphilous field layer to
pedunculate oakwood with an acidophilous field layer near the top of
the slopes. Scarwell Wood on the west side has an alder-ash woodland
with willow and a very varied and well-developed field layer on the
valley bottom. Above this there is ash-elm woodland with sycamore
and extensive Mercurialis perennis and Allium ursinum communities. A
feature of this zone are the well-developed tufa areas with a
characteristic calcicolous moss flora. The upper slopes carry oak-
sycamore woodland with some elm, birch, rowan and hazel over a less
calcicolous field layer of Rubus fruticosus, Lonicera periclymenum,
Endymion non-scriptus, Anemone nemorosa, Oxalis acetosella, etc.,
with patches of Luzula sylvatica.

alder, with yew, hazel, holly, rowan and bird- cherry locally. There
is a wide range of age classes, but some of the elm has been
coppiced or pollarded. At the southern end where the wood was once
cut-over, birch, hawthorn and willow dominate. These woods are on
limestone, but the upper levels over acidic rocks are dominated by
oak and birch. The ground flora of the lower levels is particularly
rich with abundant Myosotis sylvatica, Geranium sylvaticum, Geum
rivale, Paris quadrifolia, Chrysosplenium spp., Allium ursinum,
Luzula sylvatica and numerous ferns. The bryophyte flora is quite
rich, both in calcicolous elements on the damp boulders lower down,
and in calcifuge species on the acid loamy soil and rocks higher up.
The wood is, however, outstanding for its flora of epiphytic
lichens, which includes the relict forest species Lobaria
pulmonaria, L. laetevirens and Baccidia affinis: this is the first
definite British record of the last-named lichen.

30 ha
Grade 2
Scales Wood lies between
100 m and 250 m on a fairly steep slope of
Ennerdale Granophyre facing north-east. From its position on the
lower slopes of the High Stile range in the high fells of western
Lakeland, the wood receives a heavy rainfall of about 203 cm
annually, and the shaded aspect enhances atmospheric humidity. The
parent rock gives mainly acidic soils and the lower part of the wood
is a well-grown stand of high forest sessile oak with few
undershrubs since there is sheep-grazing throughout, though
scattered birches fulfil this role in places. The upper part of the
wood consists of fairly pure birchwood, though this is probably
serai as it lies well within the altitudinal range of oak. The
ground is generally block littered and there is a luxuriant fern and
bryophyte flora, with abundance of Atlantic species such as
Hymenophyllum wilsonii, Plagiochila spinulosa, Scapania gracilis,
Hylocomium um-bratum and the rare moss Sematophyllum novae-
caesareae, unknown elsewhere in England outside Borrowdale. At the
upper edge of the wood the grassy field layer grades into bilberry
heath with a high cover of Sphagnum capillaceum and S.
quinquefarium. There is an old record of Festuca altissima, probably
referring to the ravine of Far Ruddy Beck, where calcareous rocks
bear a more varied flora.
This site could be regarded
as an alternative to Johnny's Wood
(W.i33(e)), but is too small and limited in range of habitat,
vegetation and flora to take the place of the Borrowdale Woods as a
whole.
W.I47- LYNE WOODS,
CUMBERLAND
NY 4569.
115 ha
Grade 2
These consist of a series
of ungrazed lowland gorge woodlands along
the course of the River Lyne. The lowest section, near Kirklinton,
has only thin fringes of ash-oak-wych elm-hazel wood, and is
interesting mainly for its crags of New Red Sandstone, which is here
moderately calcareous in places and supports species such as
Myosotis sylvatica, Carex pendula, Phyllitis scolopendrium,
Polystichum lobatum and Equisetum hyemale. There is a rich bryophyte
flora. The section above Waingatehead is cut mainly through acidic
beds of Carboniferous sandstone; it has more oakwood and is notable
for the abundance of Atlantic bryophytes. There is an isolated small
colony of Hymenophyllum tunbrigense. The basic soils have a field
layer with Mercurialis perennis, Primula vulgaris, Sanicula
europaea, Stellaria nemorum and Carex sylvatica on drier ground, and
Ranunculus repens, Chrysosplenium oppositifolium, Filipendula
ulmaria and Carex remota where it is wet. The acidic brown earths
have an abundance of Luzula sylvatica, Vaccinium myrtillus, Oxalis
acetosella, Dryopteris austriaca and D. filix-mas.
The upper section, below
Kinkry Hill, is cut through Carboniferous
sandstones and shales, and has a mixture of the acidic and basic
woodland types described above. Another distinctive type on a wet
river terrace here is an ungrazed alderwood, with wet mull soils
carrying Carex acutiformis, C. paniculata, Equisetum telmateia,
Paris quadrifolia and Phalaris arundinacea. Through all sections,
the high flood level of the river produces a zone of enrichment
which supports numerous basiphilous vascular plants and bryophytes,
and these include Trollius europaeus and Geranium sylvaticum in the
upper section, which is closer to the source of the river on the
Bewcastle Fells of north Cumberland.
W.I48. GOWBARROW
PARK, CUMBERLAND
NY 4120.
85 ha
Grade 2
The southern edge of Gowbarrow
Park around Yew Crag consists of a
mixture of woodland, grassland and heath on steep slopes and bottom
lands overlooking the northern shore of Ullswater, at 150-275 m. Two
distinct kinds of woodland occur. On the low-lying ground at the
foot of the slopes the woodland is dominated by alder with a few
ash. In Dobbins Wood and higher up the valley of the Collierhag
Beck, much of the alder is open - in Dobbins Wood it was coppiced
within the last decade and has been kept open by grazing - but in
the area south and west of Yew Crag it mostly forms a closed canopy.
The soil here is a flushed silty material with boulders at the base
of the slopes, mildly acid or neutral in reaction and slightly
gleyed. The ground flora is extremely rich with numerous marshland
species especially in the open alder areas.
On the steep south- and
east-facing slopes most watercourses and
rocky bluffs are occupied by open irregular woodland in which wych
elm, ash and hazel are abundant. Many other species occur there
including bird cherry, yew and sessile oak. This kind of woodland is
best developed on Yew Crag, whence it grades westwards into a
distinct variant, resembling in some respects the woodland of
calcareous soils south of the Lake District. This lies on the steep
south-facing slopes immediately above the oak, and is characterised
by the presence of pedunculate oak, small-leaved lime and spindle
and the absence of sessile oak in the mixture which includes wych
elm, ash and hazel. The soil on the craggy slope varies considerably
in depth, stability,
base-status and wetness,
but seems mostly to be mildly acid or
neutral. The rock outcrops belong to the Borrowdale Volcanic Series
and vary from strongly acidic to markedly calcareous.
The alder woods thin out
below Collier Hagg to open, acidic, flushed
grassland and bracken on drier areas. Between the patches of crag
woodland and on the hillside above are heathland communities ranging
from bracken to a mixture of Vaccinium myrtillus, Calluna vulgaris,
Erica cinerea and Nardus stricta.
The lichen flora is rich,
both in the lower alderwoods and on the
steeper wooded slopes and cliff's. Gowbarrow supports a fine
assemblage of relic forest lichen species within which Lobaria spp.
are particularly well developed.

LOW FOREST, WESTMORLAND

no ha
Grade 2
Naddle Low Forest is situated
at 200-400 m on the slope overlooking
the lower end of Haweswater and on both sides of a re-entrant valley
joining the main river just below the foot of the lake. The aspect
is mainly north-west, but on the spur between the two main sections
varies through north to east. The parent rock belongs to the
Borrowdale Volcanic Series, and contains calcite in places, so that
the soils vary from acidic to basic brown earths, while the slopes
are generally steep and locally precipitous. The poor soils of steep
ground have sessile oakwood, but birch locally replaces oak,
evidently through selective extraction of the latter. Ash-hazel wood
is well developed on the richer soils, and where the slope flattens
to the river, beyond the dam, there is a good mixed deciduous wood,
and alder-Care* swamp in places. The slopes are thickly strewn with
blocks and here there is a profusion of ferns and bryophytes.
Lightly grazed sections of the wood have herbs such as Geranium
sylvaticum and in open places there are soligenous mires with Juncus
acutifiorus and Primula farinosa.
Naddle Low Forest shows
much the same range of habitat and
vegetational variation as the Borrowdale Woods, but is regarded as a
second choice for the following reasons.
(i) There is a much lesser
representation of good oak and a
correspondingly greater amount of probably serai birch.
(ii) There is a smaller
extent of ash-hazel wood. .
(iii) There is a lesser
range of aspect.
(iv) Though luxuriant and
rich, the bryophyte flora is much poorer
in Atlantic species, probably because of the eastern position of
Naddle Low Forest.
Naddle Low Forest has the
advantage of being in two almost
continuous blocks and probably contains a few herbs not present in
the Borrowdale Woods.

Low Wood is situated about
half way between the Borrowdale Woods and
Naddle Low Forest, on a moderate to steep and east- to south-east-
facing slope of Borrowdale Volcanic rock at 150-400 m, overlooking
Brothers Water. Both oakwood and ash-hazel wood on acidic and basic
soils are
well represented here, and many of the trees are tall and
well grown. The field communities of the Borrowdale Woods are mostly
represented, but the drier aspect gives a much lesser abundance of
bryophytes, particularly of the moisture-loving Atlantic species.
This site has too limited
a range of aspect, communities and flora
to rank as an alternative to the Borrowdale Woods, but is regarded
as an important example of hill oak and ash-hazel wood in Lakeland. .

SD 5466. 18 ha
Grade 2
The site is on a steep
slope at 15-140 m over rocks of the Bowland
Series, which consist of a mixture of sandstone, mudstone and
calcareous shales. The soils vary from shallow acid podsols through
brown earth types on ridges to deep sandy mulls (pH 6.5) on the
slopes of the two shaly ravines. The canopy, which appears to be
uneven-aged, is dominated by sessile oak and ash; also present are
birch, Scots pine, and gean. Wych elm and small-leaved lime are
locally abundant. The shrub layer is only developed to any extent in
the ravines and includes hazel, hawthorn, elder, rowan and guelder
rose.
On the podsolic areas the
ground flora is a Deschampsia flexuosa-
Vactinium myrtillus dominated community, whilst Mercurialis perennis
takes over on the neutral mull soils. Also present in the field
layer are Endymion non-scriptus, Lonicera periclymenum, Primula

a varied herbaceous field layer with mixed grasses and forbs,
including Brachypodium syhaticum, Allium ursinum, Anemone nemorosa,
Endymion non-scriptus and Mercurialis perennis as the chief
dominants. Other abundant species include Primula vulgaris, Fragaria
vesca, Potentilla sterilis, Viola riviniana, Prunella vulgaris,
Circaea lutetiana and, more locally, Paris quadrifolia and
Convattaria majalis. This wood is evidently only lightly grazed, and
is probably the best remaining limestone wood of the Wharfedale
area, the rest having been ecologically degraded in recent years by
felling or sheep-grazing.

This is a second Littondale
ashwood but lies on the opposite, north-

places. The rock is again Carboniferous Limestone and the altitude
250-370 m. The wood also contains some sycamore, a few larch and
spruce, and birch is locally abundant. The shrubs include hazel,
hawthorn and willows with bird cherry and Ribes sylvestre in places.
The middle level of the wood is broken by a line of low scar and
scree, and here, since grazing is less heavy than at the margins,
the field layer is very rich. A wide range of mesophilous and
calcicolous species is represented and includes Actaea spicata,
Paris quadrifolia, Sesleria caerulea, Cirsium heterophyllum and
Asplenium viride. Grazing has increased within the wood in recent
years and there has been modification of the field layer
communities, with grasses spreading at the expense of forbs. See

Grade 2
These two valleys north
of Ingleton lie at 120-200 m on strongly
contrasting rock types, namely Carboniferous Limestone which is
confined to the western glen, and Silurian slate in the eastern and
part of the western glen. The limestone woodland has pedunculate
oak, wych elm, ash mixtures with a range of age classes, but over
the slates sessile oak is dominant, with rowan, birch and, beside
the stream, small-leaved lime. Though the vascular flora reflects
the strong contrast in underlying lithology and is rich in
aggregate, the site is more important for its outstanding bryophyte
and lichen floras. The bryophytes include many species of calcareous
habitats, but also a number of moisture-loving oceanic species
surviving in an area of relatively low rainfall and calcareous
rocks. After the Lodore Falls in the Borrowdale Woods (W.I33), this
is probably the best locality in northern England for Atlantic
liverworts characteristic of damp, waterfall glens at low
elevations. Some of these species are unknown elsewhere in the
Pennines, for they avoid limestone. The site owes this bryological
richness, unusual also in an area of relatively low rainfall, to its
western position, the presence of relatively acidic rocks and the
probable historical continuity of tree cover in these glens. The
lichen flora includes a number of rare species of old forests,
notably Thelotrema lapadinum, Normandina pulchella, Lobaria
laetevirens and Opegrapha rufescens.

These form part of an extensive
group of woodlands at 90-150 m on
the steep sides of upper Rye Dale near Rievaulx, one of the deep
glens draining the south-western part of the North York Moors.
The woods lie on the west
slope of this valley and on both aspects
of the ridge bounding the east side. Soil conditions range from
acidic to strongly calcareous, and from dry to permanently water-
logged. On the acidic soils oak and birch dominate over a field
layer of Rubus fruticosus, Pteridium aquilinum, Vaccinium myrtillus,
Lonicera peridymenum and Luzula sylvatica. On calcareous soils,
mixed deciduous woodland of ash, field maple, wych elm, hazel and
small- leaved lime grows over Brachypodium sylvaticum, Des-champsia
cespitosa and a rich variety of herbs including Actaea spicata and
Ophrys insectifera. The lower 15 m of the valley are occupied by
fragments of alderwood and more extensive Juncus-Carex calcareous
marsh and wet grassland, with an unusual number of rare and local
species, notably Primula farinosa, Trollius europaeus, Epipactis
palustris, Schoenus nigricans and Carex aquatilis. Adjacent to the
mixed deciduous woodland is limestone grassland with numerous herb
species (e.g. Cirsium eriophorum) showing invasion by hawthorn. The
whole forms an important woodland-grassland-mire complex of great
floristic interest.

These woods are on Carboniferous
Limestone of the Yore-dale Series
in steep gorges associated with the west-east-flowing River Swale
and its small north-south-flowing tributary, East Gill, near Keld.
While forming an ecological unit, they are physically separated by a
field in the angle of the junction of the rivers. The altitude is
270-350 m, so that the woods have a submontane character.
The woods are dominated
by ash, particularly fine specimens
occurring on the south side of the Swale. Birch is important as a
constituent of the canopy toward the upper woodland edges whilst
wych elm is locally abundant near the rivers and alder follows some
small side streams on the south side of the Swale. Hawthorn, bird-
cherry, blackthorn, and rowan are present as understorey or shrubs;
hazel occurs, and is particularly well developed on some relatively
open and more level ground south of the Swale. Though variable, the
average height of the tree canopy is about 8 m.
The ground flora varies
according to the substrata which range from
limestone to acidic sandstone and, alongside East Gill, to base-rich
alluvium, but in general reflects only moderately base-rich
conditions. A disused lead mine tip with Minuartia verna forms a
scree, cutting through the wood on the north side of the Swale. The
range of forbs includes such species as Brachypodium sylvaticum, Mer-
curialis perennis, Allium ursinum, Primula vulgaris, Sanicula
europaea, Filipendula ulmaria and Viola spp. In East Gill, Campanula
latifolia and Cirsium heterophyllum also occur at lower levels and
the woodland ground flora gives way to a small piece of attractive,
wet, calcicolous meadow flora between wood and river. Ferns, notably
Athyrium filix-femina, are prominent on the south side of the Swale
among the bigger trees. A range of bryophyte communities is also
represented.

Two main types of Magnesian
Limestone of the Middle Series, Shell
Limestone Reef and Bedded Limestone, are exposed in cliffs up to 30
m high. The soils are derived from variable boulder clay and are
mainly alkaline but leaching of sandy soil produces acid conditions

sandy soils.
Beech has been planted
in some areas and sycamore has established
itself. There are also a number of mixed conifer plantations and
some plantations of hardwoods. Cypripedium calceolus and Ophrys
insectifera formerly occurred but are now thought to be extinct.
Other notable species still occurring are Pyrola rotundifolia and
Convallaria majalis.

including woodland and moorland in which juniper scrub is a
significant feature.
The small sessile oakwoods
occupy mainly the south-facing slope of a
glen draining from the Carboniferous gritstone moorlands of the
Harbottle Moors, south of the main Cheviot range. They are examples
of this woodland type in a much drier climate than that of Lakeland
or north Wales. They adjoin young conifer plantations and are now
less grazed by sheep than formerly. In Holystone Burn there is open
growth of medium-sized spreading oaks, some of which are large for a
hill wood. North Wood consists in the main of twisted, many stemmed
trees suggesting former coppicing. Underscrub is absent, and field
communities are of the type found in Lakeland sessile oakwoods on
acidic soils. There is an abundance of bracken in open places, and
the field dominants include Deschampsia flexuosa, Vaccinium
myrtillus, with much Galium saxatile, Potentilla erecta and
Melampyrum pratense. Heath mosses cover part of the ground but
Atlantic bryophytes are very few. The northern
herb Trientalis europaea

parkland is open, old woodland of ash, wych elm and sycamore, with
the richest epiphytic lichen flora known in north-east England. The
main block of woodland, estimated at 250-300 years old, is an almost
pure stand of sessile oak with only occasional beech, birch and
rowan. The shrub layer is not well developed except towards the foot
of the slope where rhododendron is abundant and hazel and hawthorn
are locally common.
Where not shaded out by
rhododendron, Luzula sylvatica forms a
continuous carpet. While the variety of field layer species is not

occupies the bottom and lower slopes of the valley and extends up
the tributary glens. Alderwood occupies the area near the stream and
this is surrounded by oak-hazel or birchwood on the higher, better-
drained slopes. The alderwood is pure and contains a good spread of
age classes from old senescent trees to young regeneration stages.
The oak-hazel woodland contains many old hazel shrubs carrying good
epiphyte communities. The ground flora under the alder is dominated
by Juncus spp. including J. effusus, jf. articulatus and Agrostis
stolonifera; also present are Mentha aquatica, Carex pendula, C.
remota, C.paniculata and Sphagnum spp. A glade containing Myrica
gale, Eriophorum latifolium, Parnassia palustris, Angelica
sylvestris and Viola palustris is present. The bryophyte flora is
rich and
alkaline runnels contain species such as Fissidens
osmundoides, Bryum pallens, Cratoneuron commutatum, Ctenidium
molluscum and Mnium punctatum. The epiphyte flora of lichens and
bryophytes is varied, because of the high humidity, and the species
recorded include Antitrichia curtipendula, Pyrenola sp. and Arihonia

This site is a complex
of saltings, salt marshes, carr and woodland
situated in the valleys and around the confluence of the rivers Fal
and Ruan. Its particular interest lies in the transition from salt
marsh through an invasive stage to tidal woodland which is rare in
Britain. The history of the site is known and studies on the
stratigraphy and the plant and animal communities in relation to
tidal submergence have been carried out. The tidal area of woodland
is dominated by Alnus glutinosa together with Salix cinereavar
atrocinerea, the willow in places forming a scrubby boundary to the
more mature woodland and extending out into the surrounding
marsh. Passing up the river
valley the tidal woodland grades into a
birch-oak wood. On the sides of the valley and, in many places
sharply defined from the marsh by a boundary ditch or bank, is a
drier acidophilous oakwood. Here sessile oak has been coppiced and
some hazel, hawthorn, rowan, willow and gorse are present. The
ground flora includes species such as Calluna vulgaris, Vaccinium
myrtillus, Blechnum spicant, Rubus sp., Lonicera periclymenum and
Holcus mollis together with bryophytes including Thuidium
tamariscinum, Dicranum majus and Hypnum cupressiforme.
In contrast to this the

CLIFFS, CORNWALL
sw 1799.
60 ha
Grade I
The cliff woodlands on
this site have a north to northeasterly
aspect and an altitude range from sea-level to approximately 150 m
at the highest point. The area of cliff over which the woodland has
developed is subject to landslips. This, combined with a friable
rock type, has given the steeply sloping cliffs a varied topography.
The tree layer is exposed to strong winds from the sea and this has
resulted in a tight wind-pruned canopy. As a direct consequence of
the varied topography and wind-pruning the canopy height varies
between i and 8 m, and is composed mainly of sessile oak together
with some birch and rowan. Of interest is the occurrence in the
canopy of wild service, a species rare in the south-west. The shrub
layer is represented by hazel, hawthorn, holly, privet, gorse and
spindle. The edges of the woodland both on the seaward side and near
the cliff top have a scrub margin in which blackthorn is well
represented. Scrubby patches are also found where recent land-slips
have caused disturbance. The ground flora of the area is extremely
varied for this part of the country and includes both basiphilous
and acidophilous areas of vegetation. Areas on the base-rich soils
support Allium ursinum, Arum maculatum, Filipendula ulmaria,
Fragaria vesca, Sanicula europaea, Primula vulgaris and
Mercurialisperennis, whilst in contrast to these may be found a
ground flora dominated by Vaccinium myrtillus, Calluna vulgaris,
Deschampsia cespitosa and Melampyrum pratense. Dryopteris aemula is
also present within the woodland. This contrast of vegetation types
is also reflected in the shrub layer. The epiphyte flora is well
developed: Lobaria pulmonaria is to be seen throughout the wood and
Sticta limbata has also been found.
W.63- BOVEY
VALLEY AND YARNER WOODS, DEVON
sx 7778.
385 ha
Grade i
This woodland complex is
one of the richest and most varied
remaining in the Dartmoor National Park. The many different
conditions of slope, aspect, and soil, together with the Atlantic
climate, support a very rich and varied flora and fauna.
The woods lie in the valleys
of the River Bovey and some of its
tributary streams on the eastern fringe of Dartmoor. Included are
Rudge Wood, parts of Houndtor and Hisley Woods, Water Cleave,
Woodash, Wanford Cleave, Lust-leigh Cleave and Neadon Cleave, all in
the main Bovey Valley, and the lower slopes of the valley of the
Becka Brook, together with Yarner Wood to the south and the smaller
detached block of Higher Knowle Wood to the east. Considerable parts
of the site are already managed as the NNRs of Yarner Wood and Bovey
Valley Woodlands.
Yarner Wood includes the
valleys of the Yarner and Woodcock Streams,
together with the intervening spur of land, giving an altitudinal
range of 240 m. The tree canopy is composed mainly of sessile oak,
with birch locally on the sites of old fields. There are also
plantations of Scots pine and other conifers, and much planting of
oak and other hardwoods has been done since the Reserve was declared
in 1951. The wood is similar in character to some of the Welsh
woodlands, but is generally drier, and some of the oaks are much
larger than those typical of western British woods nowadays. Holly
and rowan form an understorey, which is locally dense, and the
ground flora of the drier slopes is dominated by bilberry, bracken,
heather and Melampyrum pratense. The rare Lobelia wens is associated
with some of the old field sites.
In the valleys, on better
soils, ash and alder are frequent, with
hazel below, over a mesophilous ground flora including such species
as Primula vulgaris and Sanicula europaea. Osmunda regalis and
Chrysosplenium oppositifolium occur locally, together with good
epiphyte and bryophyte floras including such sensitive species as
Hookeria lucens.
The main block in the Bovey
Valley carries a variety of woodland
types, including those already described. Whereas Yarner Wood is
entirely on Culm rocks, however, much of this area is on granite,
giving relatively base-rich soils often littered with granite
boulders. On the lower slopes, bluebell and Holcus may dominate the
field layer, with a mixture of ferns and Oxalis acetosella on
flushed areas. Pedunculate oak replaces sessile oak, and ash, alder,
birch and beech are all frequent over a relatively calcicolous field
layer. The granite boulders in and near the river and the Becka
Brook carry a very rich bryophyte flora.
Higher Knowle Wood, to
the east of the main block, lies on an
unusual conglomerate rock which is probably related to the nearby
Bovey Beds (Oligocene). Pedunculate oak is the main tree, but beech,
ash and many others also occur.
The fauna of the whole
complex is characteristically western, with
such birds as the dipper, grey wagtail and pied flycatcher.
W.64- HOLNE
CHASE, DEVON
3x7271.
290 ha
Grade i*
This is an extensive valley
system of the rivers Dart and Webburn on
the southern fringe of Dartmoor. Steep-sided valleys of nearly all
aspects are present with altitude ranging from 75 to 230 m. There is
a series of oakwoods, and sessile oak predominates in the area
particularly on the valley alluvial soils. The oak occurs with other
species such as ash, beech, small-leaved lime, hornbeam, aspen, wych
elm, holly, hazel and willow. Planted larch and Douglas fir are also
present. On the richer soils a mesophilous ground flora is to be
found containing species such as dog's mercury, primrose and
Sanicula europaea. The hillsides and more acidic soils support more
pure stands of sessile oak under which a field layer dominated by
bilberry, bramble, Luzula sylvatica and Lonicera periclymenum is
present. Throughout the area, flushes are to be found containing
much Chrysosplenium oppositifolium under an ash and alder canopy; at
their edges these merge gradually into the surrounding oak woodland.
At the uppermost edges of the valleys the epiphyte flora resembles
that of the woodlands higher on the Moor although the flora is less
varied. A point of particular note is the presence of a rich
bryophyte flora, both in the woodland and in the rivers themselves;
the very rare Fissidens poly-phyllus and F. serrulatus can be found
in some quantity near Holne Bridge.
W.65_ WISTMAN'S WOOD, DEVON
sx 6177.
4 ha
Grade i
This is a small area sited
on the west-facing side of the West Dart
river valley. The wood lies between 380 and 435 m on 'clitter', a
granite block scree. In contrast with many Dartmoor woodlands
pedunculate as opposed to sessile oak is dominant. The trees are
gnarled and twisted, many having their lower branches resting on the
granite blocks which form the woodland floor. There is some rowan, a
little hazel, holly and willow (Salix aurita). The epiphyte flora,
both bryophyte and vascular, is luxuriant and epiphytic lichens are
well represented. Antitrichia curtipendula is known to occur as are
many bryophytes with a western distribution such as Douinia ovata.
The ground flora consists of a bryophyte carpet covering the blocks,
and species such as bilberry, Luzula sylvatica, Holcus mollis and
bramble grow in soil-filled crevices. Ferns form an important part
of the ground flora.
W.66. BLACK TOR COPSE,

6 ha
Grade i
Black Tor Copse is on the
northern edge of Dartmoor but having
similarities to the Wistman's Wood situation in that the area has
developed over a granite clitter on the northwest-facing slope of
the valley of the West Okement River. Pedunculate oak is again the
dominant species but the trees are taller and it is possible to walk
beneath much of the canopy. A rich and luxuriant epiphyte flora is
present containing several species such as Antitrichia curtipendula
and Douinia ovata which are of local, northern or western
distribution. The ground flora contains acidophilous species such as
bilberry together with grasses and ferns growing in crevices and on
patches of soil. The majority of the granite blocks are covered with
a carpet of bryophyte species such as Rhytidiadelphus loreus,
Thuidium tamariscinum and Plagiothecium undulatum. See also L-92,

REGIS UNDERCLIFFS, DEVON
SY 255898-333914. 320 ha
Grade i
This site, on the south
Devon coast on Lyme Bay, extends from west
of Lyme Regis to the mouth of the River Axe.
The area is of stratigraphic
importance and includes outcrops of
Triassic, Rhaetic and basal Lower Lias exposures of the sub-
Cretaceous unconformity, the most westerly exposure of the Gault
Clay as a distinct lithology, examples of penecontemporaneous
erosion in the Cenomanian Limestone and the most satisfactory
exposure of the planus Zone of the Upper Chalk in Devon. Much of the
interest of the area has arisen from a massive landslip in the mid
nineteenth century when a large field became detached from the main
cliff and moved seawards. This cliff area, now called Goat Island,
and the chasm left when it moved, have largely become covered with
woodland and scrub. A continuing series of minor slips has given an
area of varied topography as well as exposing fresh areas for
colonisation. The climate is typically western Atlantic and the
frequent damp mists encourage a profuse, vigorous growth of ferns
and climbers.
The woodland here is varied:
photographic records establish that
much of it has developed since 1905, and all ages of tree from that
date are present. Some areas have regenerated naturally, such as the
chasm between Goat Island and the mainland where ashwood has
developed, whilst others have been planted. The main species in the
planted areas include beech, ash, holm oak and Turkey oak, silver
fir and pines. Extensive areas of the reserve are covered by a
mixture of ash and field maple with a thick understorey of hazel,
dogwood, spindle, blackthorn and other scrub species. The whole area
is a mosaic of developing woodland and scrub together with abundant
climbers, traveller's joy and ivy featuring prominently.
The ground flora varies
in luxuriance depending on tree cover,
ranging from areas dominated by ivy with abundant clumps of PhylKtis
scolopendrium to almost open grassland where scrub is just
developing. Species present in some abundance include Mercurialis
perennis, Circaea lutetiana, Geranium robertianum, Carex pendula,
Rubus fruticosus agg., Dryopteris filix-mas, D. dilatata and
Polystichum setiferum together with the usual mesophilous herbs. A
feature of some areas is a low scrub with much Rubus fruticosus
agg., Ligustrum vulgare and Rubia peregrina. In proximity to this
vegetation Lithospermum purpurocaeruleum is found.

W.69- HOLNICOTE AND
HORNER WATER, SOMERSET
ss 8943. 405
ha
Grade i
This area, part of an extensive
complex of woodlands owned by the
National Trust, lies mainly on Lower Old Red Sandstone which
produces relatively poor soils. The valley bottoms contain high
forest of pedunculate oak together with ash, wych elm and birch. The
shrub layer in this valley woodland contains hazel and holly with
Rosa spp. The field layer is dominated by bramble but species such
as Geranium robertianum, Glechoma hederacea, Teucrium scorodonia,
Viola spp. and Oxalis acetosella also occur.
Higher up the slopes the
pedunculate oakwood gives way to sessile
oakwood which was formerly coppiced. The associated species here are
much more acidophilous and include birch and rowan in the shrub
layer and Blechnum spicant, Luzula pilosa, Holcus mollis, bracken
and bilberry in the field layer. The acidophilous oakwood gradually
merges into moorland on its upper edge with Calluna vulgaris, Erica
cinerea and Ulex sp. The upper edge of the woodland is particularly
exposed and the wind shapes the canopy here to near ground level.
The lichen flora is very
rich both in numbers of species (no) and in
the presence of many rarities, such as Usnea articulata, which are
now confined to south-western England because of air pollution
elsewhere. This assemblage of species is very characteristic of
ancient forest areas in northwestern Europe.
This is an extensive area
of characteristic Exmoor woodland which
shows the transition from moorland to valley woodland particularly
well. It is also an important wintering area for the Exmoor red deer
which form one of the three largest concentrations of red deer in
England.

GORGE (LEIGH WOODS), GLOUCESTERSHIRE, SOMERSET
ST 5675.
105 ha
Grade i
Leigh Woods are situated
on the western side of the gorge of the
River Avon at Bristol. The area covers those woodlands on the
plateau and on the gorge side.
The plateau woodland occurs
on a shallow marl and a clay soil. A
mixture of sessile and pedunculate oak is present together with ash,
wych elm and small-leaved lime. Yew is found on some of the more
stony sites. Beech has been planted in the area and occasional
specimens of hornbeam are to be found. An important consideration in
this region is the number of rare endemic whitebeams (Sorbus spp.)
present in the woodland. S. wilmottiana and S. bristoliensis are
endemic to this area whilst S. eminent, S. porrigenti-formis and S.
anglica are all local limestone species. The ground flora contains
the common species such as Mer-curialis perennis, Endymion non-
scriptus, Euphorbia amygda-loides, Fragaria vesca, Viola sp.,
Anemone nemorosa and Rubus fruticosus agg., as well as those of more
particular note such as Aquilegia vulgaris, Carex digitata, Neottia
nidus-avis, Rubia peregrina, Orobanche hederae, Lathraea squamaria
and Helkboris viridis. Ferns include Thelypteris phegopteris and
Polystichum setiferum.
The bryophytes of this
area include Dicranum montanum, D. strictum
and Nowellia curvifolia.
The scrub woodland of the
gorge side, particularly near the quarry
areas, is of particular conservation value as it contains a mixture
of the usual calcareous scrub species, rare Sorbus spp. and in the
associated grassy areas rare plants including Veronica spicata ssp.
hybrida, Hornungia petraea, Carex humilis, Potentilla
tabernaemontani, Trinia glauca and Scilla autumnalis.
There is an interesting
list of Lepidoptera recorded. The scarce
hook- tip moth was formerly found in association with the small-
leaved lime.

W.yi. MENDIP WOODLANDS,
SOMERSETGrade i (
a) Rodney Stoke ST 4950.
35 ha
Although five facies of
ashwood and one each of oak, lime and elm
have been recognised the intermediate types are so extensive that
the area is best considered as a varied ash-wood. These woodland
types occur over Carboniferous Limestone with some areas of
Dolomitic conglomerate. Pedunculate oak is an important associate
and field maple, wych elm, small-leaved lime and whitebeam are of
lesser importance. Other species which occur are crab apple,
blackthorn, hawthorn, buckthorn, sallows, elder and wayfaring tree.
Holly and yew however are rare, as are specimens of the endemic
Sorbus anglica and of wild service.
Spurge laurel is unusually
common particularly on the rockier
slopes, and privet occurs extensively. Under more open conditions
spindle and dogwood occur. Ivy is abundant but honeysuckle is not
common and traveller's joy is rare.
The dominant species of
the ground flora are dog's mercury and ivy
and widespread associates include Ranunculus ficaria, Anemone
nemorosa, Endymion non-scriptus, Primula vulgaris, Galeobdolon
luteum, Euphorbia amygda-loides, Campanula trachelium, Lithospermum
purpuro-caeruleum, Geranium robertianum, Viola spp., Colchicum
autumnale and Phyllitis scolopendrium.
The fauna includes a characteristic
range of species with no
particular rarities.
The Mendip Woodlands are
an interesting and floristic-ally rich
variant of the ashwoods found throughout Britain
on Carboniferous Limestone.
Rodney Stoke is the best example of the
drier facies of this woodland type. The woodland interest is
enhanced by the limestone grassland and abandoned agricultural land
which also occur in the reserve.
(b) Asham Wood
ST 7045.
195 ha
This wood lies on a steep
limestone gorge with a cliff and alluvial
floor. The western area is a plateau woodland. The presence of a
stream is an unusual feature of these Mendip Woodlands.
Ash is dominant but there
is a very extreme variety of trees and
shrubs. Small-leaved lime is common and other tree associates are
wych elm, pedunculate oak, gean, birch species, alder, yew (rare),
and field maple. The shrubs include dogwood, hazel, hawthorn,
spindle (rare), holly (rare), crab apple, blackthorn, blackcurrant,
gooseberry, sallows, whitebeam, rowan, elder, wayfaring tree and
guelder rose.
The ground flora of Asham
Wood contains a great variety of limestone
species although it is unusual that Daphne laureola and Lithospermum
purpurocaeruleum are absent. Particularly notable plants here
include Polygonatum multi-florum, Convallaria majalis, Dipsacus
pilosus, Colchicum autumnale, swarms of the Geum hybrids (G. urbanum
x G. rivale), Vicia lutea and V. sylvatica.
In addition rare Diptera
have been recorded as well as the wood
white Leptidea sinapis butterfly and the rare mountain Bulin snail
Ena montana.
The importance of this
floristically outstanding Mendip ashwood has
long been recognised and it represents the wetter facies of this
woodland type (cf. Rodney Stoke).
(c) Ebbor Gorge
ST 5248.
45 ha.
The site is on the south-west-facing
slope of the Mendip hills and
consists of a steep-sided gorge in Carboniferous Limestone together
with an associated tributary valley. Added interest is given to the
site by caves of palaeonto-logical value. The canopy of the mature
woodland is dominated by ash and pedunculate oak. Other species
present are wych elm, beech and hornbeam (rare). The understorey,
together with the scrub that is a feature of the area, contains a
range of species and includes field maple, traveller's joy, dogwood,
hazel, spindle, ivy, holly, buckthorn, small-leaved lime, wayfaring
tree and guelder rose. The woodland has been managed in the past and
most has been coppiced to some extent.
The ground flora is indicative
of the basiphilous nature of the
site, dog's mercury, wood anemone, bluebell and Asperula odorata
being abundant together with primrose, Sanicula europaea, Ajuga
reptans, Circaea lutetiana, Galeobdolon luteum, and Viola sp. A more
mesophilous vegetation is represented by patches where bracken,
Lonicera periclymenum, bramble and grasses are present. In the
sheltered gorge a damp woodland facies is found; bryophytes are
abundant as is Phyllitis scolopendrium. Scree areas are present
within the woodland area in which scattered ash regeneration is to
be found together with plants of Geranium robertianum.
W.J2. COTSWOLD
COMMONS AND BEECHWOODS, GLOUCESTERSHIRE
808913-9011.
740 ha
Grade i
Although there are many
fine stands of beechwoods in the Cotswolds,
the Birdlip-Painswick Woods are regarded as the finest example. The
high forest beech here varies in age from about 300 years downwards,
but the majority appear to be 150-160 years. The understorey of
holly and yew is sparse, and only locally forms a closed canopy.
Natural regeneration of beech, ash, holly and yew occurs, aided by
the recent thinning of some of the canopy. The field layer consists
mainly of Oxalis acetosella, Mercurialis perennis, Anemone nemorosa,
Sanicula europaea, Circaea lutetiana, Helleborus viridis and Daphne
laureola, but numerous other species have been recorded, including
Cephalanthera rubra, Monotropa hypophegea, Neottia nidus-avis,
Pyrola minor, Epipactis leptochila, E. vectensis, Convallaria
majalis and Aquilegia vulgaris. Common rights exist over the land
and this, coupled with the fact that the area carried beechwood in
the fourteenth century, suggests that the woodland here is primary.
The neighbouring woods
of Buckle, Witcombe, Cranham and Brockworth
are also dominated by beech with an admixture of ash. Some appear to
be of coppice origin. Holly forms the main understorey, but the
absence of old individuals suggests that it has invaded recently.
Within Cranham Wood is an open area, formerly grassland, now being
invaded by a considerable variety of trees and shrubs, including
beech, ash, yew, holly, hawthorn, whitebeam, hazel and oak. It
appears that this is developing towards 'mixed beechwood' and
constitutes an important variant of beech woodland.
The Sheepscombe Wood complex
is extensive and lies on both sides and
round the head of a valley above Sheepscombe. Although partly under
conifers, there are substantial areas of beech woodland containing
rare species. Together with Saltridge Hill Wood it is almost
contiguous with the Birdlip-Painswick Woods.
The Painswick Beacon area
is open grassland, scrub and small copses
surrounded by extensive beech woodland which is used intensively by
the public as an open space for recreation. The higher parts of the
Hill, particularly the flat plateau, are used as a golf course, on
which Erachy-podium pinnatum has been controlled by mowing. Many of
the grasslands accessible from the road are used as carparks.
The lower slopes of the
Hill are old quarry workings with typical
Cotswold grassland species, being well-known for the abundance of
musk orchids Herminum monorchis, pyramidal orchids Anacamptis
pyramidalis and fragrant orchids Gymnadenia conopsea. Colonisation
by subspon-taneous Scots pine has occurred in most of the old
quarries - in some places trees are 6-10 m tall. Seedlings are
widespread. Grassland is of the Brachypodium pinnatum-Bromus erectus
type with a little Festtica ovina, Koeleria gracilis and Briza
media. Cirsium acaulon is frequent, with good quantities of Lotus
corniculatus and Anthyllisvulneraria. Hieracium exotericum, which is
widespread on the open screes and quarry floors, is a feature of the
Cotswolds.
Juniper is uncommon, 12
bushes being found in 1968, most of them 30-
46 cm high, although three moribund 1.2-1.5 m examples were found in
mixed scrub under pine.
W-73. FOREST
OF DEAN, GLOUCESTERSHIRE
Grade I
The Forest of Dean, like
the New Forest, was a Royal Forest which
has survived as a large area of woodland. Although it has been
exploited, mainly for large timber, for centuries the woodlands have
been maintained by planting and careful management. In the past few
decades large areas of The Dean have been converted to conifers but
existing deciduous woodland still reflects differences in the
underlying rocks.
The central region lies
on Coal Measures from which a clay-loam soil
has developed and which carries oak (Quercus robur) woodland and a
poor, calcifuge ground flora. Surrounding this acid area are
limestone and Old Red Sandstone. These form more fertile soils which
bear a variety of woodland types over a richer ground flora. Oak
woodland, which is often pure but may contain birch and beech,
commonly grows over a bluebell, Holcus mollis and bracken field
layer. In the more acid areas this is replaced by bilberry, and in
the more base-rich areas by Sanicula europaea, Circaea lutetiana and
primrose. Woodlands on the limestone are often mixtures of oak,
beech, lime, ash and a variety of shrubs.
Conservation in the Forest
of Dean, like the New Forest, is best
effected by a broad agreement covering the whole of the Forest.
Among sites which together constitute a more or less complete range
of woodland types, the following are regarded as the most important.
See also W.g5.
(a) Nagshead Inclosure
so 6008. 28 ha
This area of mature, broad-leaved
woodland planted in 1814 lies on
the Pennant Sandstone (Coal Measures). The main species is
pedunculate oak with sweet chestnut, beech, birch and gean. The
western part, which has been closed to grazing since 1947-48, has a
developing and dense understorey of holly, rowan and other species
and some tree regeneration, but not of oak. The eastern part remains
open to grazing and has a sparse and scattered understorey of holly
and rowan.
The field layer is dominated
by Holcus mollis, Pteridium aquilinum
and bramble with Deschampsia flexuosa, Endymion non-scriptus and
Oxalis acetosella locally abundant.
This is a good example
of the older age class of Forest of Dean
oakwood on the Coal Measures. Since 1942 it has been the site of
important ornithological studies mainly in connection with a series
of nest boxes which totalled 238 in 1964. The four important species
breeding in the boxes are pied flycatcher, redstart, blue tit and
great tit. All these species nest here in some numbers and there are
no other nest box areas in Britain where so many pairs of pied
flycatcher and redstart breed. The study of the pied flycatcher is
the most prolonged ever made and only Wytham, near Oxford, has a
titmouse study of comparable size and duration. Recently a study of
the wood warbler has been started and almost the whole population of
adults and young have been ringed. There is nothing on a comparable
scale elsewhere in Britain.
(b) Dingle Wood so 5611.
9 ha
This woodland lies on Carboniferous
Limestone which has been
quarried in the past. The result is a series of deep pits and
gullies (or 'scowles') surrounded by irregular cliffs which have
been abandoned for long enough to allow woodland to develop
naturally. Part of the area has been planted.
The woodland consists of
a great variety of species with beech and
wych elm often dominant together with holly and yew in the shrub
layer. Other trees present include birch, sweet chestnut, ash, oak,
sycamore and rowan with a scattered shrub layer of holly and yew
together with field maple, dogwood, hazel, hawthorn, willows, elder,
roses and guelder rose.
The herb layer contains
a rich variety of calcicolous species with
Paris quadrifolia, Pyrola minor, Colchicum autumnale and Neottia
nidus-avis of particular note. A good calcicolous bryophyte flora
also occurs.
The woodland is particularly
notable for the richness of its tree,
shrub and herb layers and the scowles are floristically some of the
richest areas of the Dean Forest.
(c) Speech House so 6212.
18 ha
An area of open woodland
with very ancient oaks, beeches and
hollies. The soils are poorly drained acid loams and patches
ofjfuncus effusus occur. The ground flora is mostly a Pteridium-
Rubus carpet with large areas of Agrostis tennis grassland.
The combination of large
trees and open conditions has perpetuated
an outstandingly rich epiphytic flora and 53 epiphytic lichens and
15 epiphytic bryophytes have been recorded. The epiphytic flora is
one of the richest in central lowland England and is exceeded only
by that of some of the ancient parks, e.g. Moccas Park in
Herefordshire. Usnea spp. are now rare in the forests of lowland
central, north and east England but they are finely developed here.
Alectoria fuscescens is a species of northern (boreal) distribution
and the Parmelias, especially P. caperata, show a luxuriance not
otherwise seen in midland England. Per-tusaria hemisphaerica and
Thelotrema lepadinum are probably relic species of the old forests
as is P. flavida which is rare everywhere. Other relic species may
be Haematomma elatinum, once thought to be confined to south-west
Ireland and north-west Scotland, but now known in widely scattered
areas of Britain, and Normandina pulchella, formerly considered as
highly Atlantic.
W-74- COLLINPARK

It is an overgrown coppice woodland of up to about 40 years' growth,
dominated by sessile oak and small-leaved lime, with local
concentrations of silver birch and a few ash and poplar. Wild
service is also locally abundant and regenerating profusely. The
sparse shrub layer includes hazel, broom, crab apple and willows.
Soils are mostly heavy, neutral to acid. The ground flora has
abundant bluebell and dog's mercury and a range of species including
Galeobdolon luteum, Primula vulgaris, Pteridium aquilinum,
Deschampsia cespitosa, Carex pendula and Chrysosplenium
oppositifolium. Along the northern margin there is a massive
causeway embankment and associated moat. The latter is filled with
organic material with a fen-like flora, whilst the calcareous
subsoil brought to the surface on the embankment has enabled
calcicolous species such as wych elm, field maple and dog's mercury
to become established.
The wood is selected as
a representative of damp calcifuge lime
woodland in western Britain, complementary to the Lincolnshire lime
coppices, where, however, the oaks are almost entirely pedunculate.
W.75- HUDNALLS, GLOUCESTERSHIRE
so 5404, so 5303. 75 ha
Grade i
The wide range of semi-natural
coppice types in the lower Wye valley
area includes a series on the more acidic sandstone rocks in which
beech is the main constituent, even though other species are usually
mixed with it. Much of this woodland occurred on the Monmouthshire
side, where it has all, as far as is known, been allowed to develop
to high forest or, more commonly, has been replaced by a variety of
plantations. On the Gloucestershire side substantial tracts of these
calcifuge coppice types survived as coppice into the present
century, particularly to the north and south of the St Briavels
meander, and extending north to the Staunton area. Recently,
however, much has been cleared, notably at Lords Grove near
Monmouth, and north from Wyegate Hill, but one group, centred on
Hudnalls, remains virtually intact.
Hudnalls and adjacent woods
occupy steep, north- and west-facing
sandstone slopes. Much of the woodland is a mixture of beech and
sessile oak over a ground flora of Luzula sylvatica, Blechnum
spicant, Lonicera periclymenum and Melampyrum pratense. Part of this
is a mixture which retains the small-coppice structure, but other
parts on the steepest slopes are ancient beech high forest with very
few oaks and a negligible field layer. Along the stream sides and in
parts of the coppice, ash and small-leaved lime occur. All these are
on strongly acid soils, but where streams drain down the slope and
along flushed areas at the base of the slope a far richer coppice
type occurs in which wych elm, ash and hazel are more abundant and
the ground flora is extremely rich.
Hudnalls has a complex
management history. Part was common woodland,
but adjacent parts are coppice-with-68 Woodlands standards.
Structural differences coincide partly with walls within the wood
and are clearly a relict of use and management, but the composition
of the wood appears to be natural.

of the wood the trees overhang a bank and then estuarine mud in
which are patches of Spartina marsh. In the lower parts of the wood,
rowan, alder buckthorn and gorse are to be found.
The ground flora in the
upper parts and hazel coppice region is
dominated by bluebell together with wood anemone, bramble, Blechnum

This is a very fine example
of coppice-with-standards woodland with
pedunculate oak over hazel on Oxford Clay. Ash is common and other
associates are field maple and alder (along the ditches). In
addition to hazel the shrub layer contains hawthorn, blackthorn,
sallows, guelder rose and Rosa spp.
The oaks are particularly
well-grown here and, as the understorey
has not been cut extensively for many years, an interestingly varied
understorey is developing.
The field layer is characteristic
of clay woodlands with species
such as Anemone nemorosa, Rubus fruticosus agg., Endymion non-
scriptus, Viola spp., Brachypodium sylvaticum, Fragaria vesca,
Galeobdolon luteum, Mercurialis perennis, Ajuga reptans, Allium

Ashen Copse has features
resembling the eastern boulder clay
coppices and is thus, like Salisbury Wood, Monmouthshire, one of the
westernmost of this type. It is adjacent to Longleat Woods and Park,
additional remnants of the former Selwood Forest. These woods which
contrast with Ashen Copse include ancient oak-beech high forest,
mature but younger high forest and old, open park woodland, which
together have a very rich epiphytic lichen flora including numerous
old forest relic species.

W.I. BLEAN
WOODS, KENT
TR 1060.
305 ha
Grade 1
The Blean forms the most
extensive area of nearly continuous
woodland on the London Clay in south-eastern England. Within this,
Blean Woods National Nature Reserve (NNR) forms a typical example.
The whole area has a long-standing
tradition of management as
coppice with-standards with sessile oak as the dominant standard.
Sessile oak coppice, mixed in part with beech, occurs in a large
area on the western boundary, whilst the latter is dominant in a
very small central area of open high forest. Hornbeam coppice
dominates the northern parts and sweet chestnut coppice dominates
the south-central and south-eastern parts and much of Crawford's
Rough. Rowan is widespread whilst wild service and aspen are
becoming increasingly common in the newly coppiced areas. Alder and
guelder rose are also widespread. Along the southern parts of the
wood the London Clay is overlain by two patches of recent 'head
gravel', part of the terrace of an ancient valley floor of the Great
Stour River. This acidic gravelly drift supports dense chestnut
coppice with a honeysuckle, bluebell and Luzulapilosa field layer. A
small area of ash coppice with pedunculate oak and hazel has a
ground flora of Sani-cula europaea, Euphorbia amygdaloid.es and
Ajuga reptans. Also in the south-east part of the wood are acidic
areas with Calluna, Carex binervis, C. ovalis, C. demissa, Molinia
caerulea, Sieglingia decumbens and Dactylorchis maculata, all rare
in north-east Kent where heathlands are scarce. The areas of
recently coppiced oak-beech hornbeam woodland have a rich ground
flora which includes Luzula sylvatica, Teucrium scorodonia, Milium
effusum, Melica uniflora, Lathy-rus montanus, Hypericum pulchrum,
Sarothamnus scoparius and Ruscus aculeatus. In the more dense old
hornbeam coppice Crataegus oxyacanthoides is an occasional associate.
The Blean has been a well-known
haunt for entomologists since the
latter part of the last century. It was originally scheduled to
preserve one of the few remaining colonies of heath fritillary
Melitaea athalia, the larvae of which feed on Melampyrum pratense.
This plant flourishes particularly in the light phase of coppicing
and along ride margins and is again plentiful in the Reserve. As a
result, for example during early July 1969, following coppicing,
this butterfly was a common sight in the open areas of the wood.
Recent studies in the Reserve have revealed a wealth of rare species
of a wide range of invertebrates. The wood ant Formica rufa is
abundant in parts of the wood and some 15 species of myrmicophilous
beetles have been found in its nests. A number of rare staphylinid
beetles have been found in the wood including Gyrophaena joyioides
(only known British locality), Borboropora kraatzi (first British
record for over 100 years) and Staphylinus fulvipes which is quite
common locally. Acritus homoepathicus (Coleoptera, Histeridae) is
abundant in fire sites in the coppiced areas. The millipede
Polyzonium germanicum, which has its British distribution almost
restricted to Kent, is common in the Reserve, as is Choneiulus
palmatus, another millipede more commonly recorded from greenhouses
and gardens. Among an impressive list of Heteroptera bugs is
included Charagochilus weberi (Miridae), a species new to Britain.
The large area of woodland of The Blean provides a stepping stone by
which many continental species enter the British Isles and become
established.
W.2. HAM
STREET WOODS, KENT
TR 0034.
210 ha
Grade 1
These woodlands, parts
of which are NNR, lie on the plateau, slopes
and valley bottoms over Lower Weald Clay. Structurally they are
coppice-with-standards throughout, although there is a wide range of
coppice types. The standards are oak (mostly Quercus robur, but with
about 10% Q. petraea) with a proportion of birch (mostly Eetula
pubescent) which has entered as a weed species following the cutting
of the coppice. Wild service, gean and aspen also occur as 'weed'
standards.
Four types of coppice occur
on the plateau areas. These, defined by
their dominant species, are clearly the product of past management.
Hornbeam coppice is the most widespread, some of the stools being
massive indicators of the long history of such coppice on at least
part of the site. Hazel coppice occurs mainly on the valley slopes.
Chestnut coppice, still actively worked, occurs mainly in the
northern block. Oak coppice occurs in Carter's Wood, but has
evidently arisen from the felling of standard oaks. Other shrub
species occur within these types, including willows (Salix
atrocinerea and S. capred), both hawthorns and holly. The presence
of midland hawthorn as well as wild service is circumstantial
evidence that at least parts of Ham Street Woods are primary.
The woodland is diversified
by the presence of valleys and rides.
The former, which contain the richest areas floristic-ally, have ash
and alder woodland, worked as coppice, with midland hawthorn and
elder.
The ground flora develops
and changes cyclically as coppicing
proceeds, being least developed as the coppice becomes dense.
Although the proposed future management of large areas of the
woodland is of coppice-with-standards, much of the present wood is
old, neglected, hornbeam coppice in which the ground flora consists
of wood anemone, primrose, bluebell and honeysuckle. In the gills
dog's mercury is locally dominant. Where the canopy is more open
bracken and bramble are abundant. Rides in the north have heather,
gorse and Potentilla erecta, indicating acid conditions which
contrast with the base-rich nature of the valleys. The bryophyte
flora, which includes such noteworthy species as Eucalyx hyalinus,
Rhytidiadelphus loreus and Hylocomium brevirostre, supports the
conclusion that woodland has been continuous on this site.
Ham Street Woods have long
been famous entomologically.

Lying on steep Chalk slopes,
these woods have soils 30-60 cm deep of
calcareous loam with few Chalk particles and a high siliceous
fraction. They consist of mixed coppice of ash and pedunculate oak
with some hornbeam, hazel and field maple, and only a few poorly
grown standards of pedunculate oak. Beech is rare and entirely
confined to the margins. The flora is very rich. Sladden Wood,
probably the best single site within the group, includes Orchis

nidus- avis, Platanthera chlorantha, Paris quadrifolia, Helle-
borus viridis, Mercurialis perennis, Sanicula europaea, Adoxa
moschatellina, Campanula trachelium, Ranunculus auricomus, Galium
odoratum, Pimpinella major, Angelica sylvestris, Deschampsia
cespitosa and Veronica montana.
The significance of these
sites is that almost everywhere else on
Chalk scarps the woodland is dominated by beech over a thin soil:
possibly the Alkham Valley Woods lie on a relict soil type.

This site lies on a plateau
of chert gravel derived from acidic
Hythe Beds giving rise to a podsolised soil, falling to a valley in
which first brown forest soils then calcareous soils derived from
Kent ragstone and base-rich peaty soils occur in an apparent catena.
Corresponding with this are four woodland types, respectively (i)
sessile oak high forest and coppice over Vactinium myrtillus-Calluna
vulgaris-Blechnum spicant, with Luzula sylvatica and Pyrola minor
locally; (2) sessile oak high forest with birch and holly with a
transitional ground flora of Endymion non-scriptus, Rubus fruti-
cosus, Pteridium aquilinum, Euphorbia amygdaloides, and Primula
vulgaris; (3) mixed coppice and high forest of pedunculate oak,
field maple, ash, hazel and wych elm with a ground flora indicative
of base- rich conditions, including Mercurialis perennis,
Sanicula europaea, Galium odoratum, Helleborus viridis, Lathraea
squamaria, Listera ovata and Adoxa moschatellina; and (4) alder carr
with Chrysosplenium oppositifolium, C. alternifolium, Carex strigosa
and Equisetum telmateia.
With this exceptional range
of habitats, the vascular flora is very
rich. Both rowan and common whitebeam are present in the sessile
oakwood, together with the hybrid. Numerous bryophyte and lichen
species are recorded.
W-5- ASHOLT
WOOD, KENT
TR 1738.
70 ha
Grade i
Asholt Wood lies on gently
undulating ground at the foot of the
Chalk escarpment. Springs rising at the base of the Chalk flow
through the wood. The soil, developed from Gault Clay and downwash
from the Chalk, is highly calcareous but poorly drained. Its texture
varies from heavy clay to clay loam, and small elevated areas appear
to be neutral or mildly acid in reaction. Structurally the wood is
mostly pedunculate oak standards over a range of coppice types, much
neglected for the most part, but in places recently coppiced after a
period of neglect. Much of the coppice is ash and hazel with some
maple, dogwood and willows, but on the apparently acidic knolls,
there is some hornbeam-ash coppice, and along the flood zones beside
the streams a mixed coppice of alder, ash, maple and hazel has
developed. The ground flora is rich, but no nationally rare species
have been recorded.
This site is selected as
a south-eastern counterpart of the chalky
boulder clay coppices of East Anglia and the Midlands. It differs
from them in having valley alder coppice, and lacking oxlip Primula
elatior and Geum rivale. Other examples of this type are known, and
one - Ryarsh Wood, Kent - has a richer flora, but Asholt is regarded
as the best example because it has a canopy largely free of aliens,
and is contiguous with a chalk grassland site (L.I5).

Grade i
This is part of an extensive
tract of woodland, scrub and grassland
on the Chalk scarp and plateau of the North Downs all of which is of
considerable scientific importance. Crookhorn Wood itself is a
mature beechwood with ash and field maple in the canopy, and an
understorey of yew. Structurally it is diverse, with a mixture of
age classes, including some very old trees, forming a closed canopy.
The humus lies deep over a shallow soil, and the ground flora,
though sparse, includes Cephalanthera damasonium, Neottia nidus-avis
and Daphne laureola. On the plateau over Clay-with-Flints the
woodland is mainly pedunculate oak with some coppice of hazel, ash
and sweet chestnut. Parts of the adjacent grassland have been
invaded by scrub in which ash is (unusually) rare and the most
abundant species are whitebeam, silver birch and dogwood, with
patches of yew. Within this scrub Helleborusfoetidus, Aceras
anthropophorum and a fine colony of Orchis purpurea are known.
The woodlands on Wouldham-Detling
Escarpment are similar but contain
serai ashwood as well as the range of types present in Crookhorn
Wood.

ESCARPMENT, KENT
TQ 723648-795588.
440 ha
Grade i
The woodlands on this south-west-facing
scarp slope of the North
Downs are extremely variable. They include almost the entire range
of types associated with the Chalk scarp and Clay-with-Flints
plateau sites. On the plateau, pedunculate oak woodland is prevalent
over coppice which is partly of sweet chestnut, but mostly a mixture
with hazel, ash and hawthorn. The field layer includes the range of
communities from Mercurialis perennis-Sanicula europaea, through
Endymion non-scriptus to Rubus fruticosus and Deschampsia cespitosa.
The thin rendzina soils on the slopes bear beech woodland in part,
and mixtures of ash, yew and hazel, over a discontinuous field
layer. At the south-eastern end on Boxley Warren, chalk scrub of
yew, hawthorn, dogwood and whitebeam is developing towards woodland.
The Escarpment contains
a wide range of woodland types which
individually may be better represented by examples elsewhere: e.g.
beechwoods at Crookhorn Wood; yew-woods at Kingley Vale; plateau
woods at Box Hill. Nevertheless the woodland complex taken as a
whole and in conjunction with the associated grassland and scrub
qualifies for grade i status (see also L.io).
W.8. BIGNOR HILL,
SUSSEX
su 9713.
160 ha
Grade i
Bignor Hill is at the southern
end of extensive woodlands situated
on the north- and east-facing Chalk scarp slopes. These woods are
not quite continuous, and stretch in a broken chain from Duncton
Down in the north to Great Bottom on the dip slope in the south.
Beech is dominant, with ash as a more or less constant associate.
The stand has a limited range of age, but recent thinning has
facilitated some regeneration, mainly of ash. Birch and field maple
are also present in the canopy, while the shrub layer of yew,
whitebeam, dogwood and spindle is reasonably well developed. Ground
flora communities cover the usual range from Mercurialis perennis-
Sanicula europaea on dry, calcareous soil to Endymion non-scriptus-
Rubus fruticosus on the deeper plateau soils. Local variations occur
on Duncton Hanger where, in a valley along a springline, a wych elm
woodland has developed; at Bignor Hill, where an ashwood on scree
includes the only locality in the south-east for Thelypteris
robertiana; and at Great Bottom, where on the west side there are
some of the largest and possibly oldest pollarded beeches in the
south-east.
There are many other stands
of beechwood on the South Downs, but
those at Bignor Hill are regarded as the best developed, with a
number of local variations related to geological and edaphic
differences.
W-9- SAXONBURY
HILL/ERIDGE PARK, SUSSEX
TQ 5734.
600 ha
Grade i*
This site comprises an
ancient deer park, a more recent park now
used for deer, and adjacent woodlands on Saxonbury Hill, situated in
the High Weald. The parks, particularly the northern half of the Old
Park, have an open woodland of
ancient oaks, maple, ash
and beech beneath which the ground
vegetation is a mosaic of bracken, Molinia caerulea and heather
heath, and in the lower parts on Wadhurst Clay a relatively rich
woodland ground flora has developed. Small, low-lying areas are
occupied by alder carrs, small areas of calcareous fen and some
acidic flushes. Saxonbury Hill includes a mixture of woodland types.
Mature, closed oak-beech forest occurs on plateau areas where yew
and holly are also frequent. In the valley, alder occurs beside the
stream, and on flushed parts of the slopes near the valley bottom.
On the drier slopes woodland of oak and birch occurs locally.
Taken as a whole the site
has one of the richest epiphytic lichen
floras of any single park in Britain. So far 167 species have been
recorded. It is the only site in south-east England where a well-
developed Lobarion association occurs. Numerous species
characteristic of old forests have been recorded, including Lobaria
pulmonaria, L. laetevirens, Nephroma laevigatum, Parmeliella
plumbea, Leptogium lichenoides, L. minutissimum, Buellia schaereri,
Parmelia crinita, Xylographa vitiligo and Dimerella lutea. Bryophyte
epiphytes include Frullania fragilifolia and Orthotrichum
stramineum, which are otherwise unknown in south-east England. In
Saxonbury Hill woods there is a small sandrock outcrop with
Dryopteris aemula and Hymenophyllum tun-brigense, and a number of
western bryophytes such as Scapania gracilis and Bazzania trilobata.
Although much of the central
area of the Old Park has been reseeded,
this site is undoubtedly one of the most important of all the
ancient parklands selected, because the woodlands are diverse and
the epiphyte flora is unsurpassed.

woodland on Chalk and oak on the clay, of which the former is much
the more extensive. The yew woodland is almost pure in parts, but
with a range of age classes. Elsewhere within the yew-wood, ash is
common, and whitebeam, holly and blackthorn occur sparingly. Juniper
formerly occurred there abundantly but successional changes have
greatly reduced its extent. The field layer is absent, or
represented by sparse development of, for example, Fragaria vesca
and Brachypodium sylvaticum. The woodland on clay is dominated by
pedunculate oak and ash, with an understorey of yew, holly and
hawthorn.
The Kingley Vale woodland
is selected as a representative of yew-
dominated stands on calcareous soils. As such it is regarded as the
most important site in Britain and is reputed to be the best yew-
wood in Europe. Though yew woodland occurs elsewhere, e.g. Old
Winchester Hill, Blackcliff, Box Hill, the stands are either less
extensive or are mixed with other, taller species such as beech. A
further important feature of Kingley Vale is the presence of all
stages in the development from scrub
on grassland to mature yew
woodland. See also L.Q.
W.II. EBERNOE COMMON,
SUSSEX
su 9727.
110 ha
Grade i
Ebernoe Common and Willand
Wood together form a continuous block of
woodland with a wide range of structural, floristic and soil types
in the western Weald. The underlying strata range from heavy clay to
sandstone and limestone, giving rise to the three main soil types of
the area.
Ebernoe Common has three
main woodland types. The most extensive is
mature, closed beech woodland with some pedunculate oak and a dense
understorey of holly with some yew. Some beech have fallen recently
to produce gaps in which regeneration occurs sparingly. Along the
eastern side and over base-rich soils, younger mature woodland of
field maple, pedunculate oak and ash is found, with a few beech and
a sparse understorey of holly. At the northern end a third type
occurs, open ancient woodland of oak and beech with scattered
thickets of holly. Not all the Common is wooded: large areas remain
under grass and bramble, and other parts of former grassland are now
occupied by scrub of gorse, blackthorn and willow with thickets of
oak and birch saplings. The ground flora, virtually absent beneath
the closed beech canopy, varies considerably between the Mercurialis
perennis-Primula vulgaris-Sanicula europaea community of the base-
rich soils to Rubus fruticosus and Deschampsia cespitosa on the
clays. The local species include Narcissus pseudo-narcissus, Ruscus
aculeatus and Carex strigosa. The epiphyte flora is fairly rich, but
lacks a number of old forest indicators. In addition to the woods,
scrub and grassland, the Common contains large ponds and marsh areas.
Willand Wood consists of
coppice-with-standards typical of West
Sussex, with pedunculate oak standards over mixed coppice of
hornbeam, hazel and ash. The ground flora is dominated by wood
anemone, bluebell and primrose.
W.I2. WAKEHURST
AND CHIDDINGLY WOODS,
SUSSEX
TQ 3331, TQ 3432.
150 ha
Grade i
These woods occupy the
steep slopes and bottoms where the Ardingly
and Cob Brooks have cut deeply incised valleys and exposed large
areas of Tunbridge Wells Sandstone. At Chiddingly, the woodland on
the plateau has been largely modified, consisting now in parts of
scrub, coppice and planted pine with a number of exotic tree
species. However, on the rocky slopes below the sandrock outcrops, a
dry oak (mainly pedunculate) wood with birch, yew, holly and some
beech, shades ground covered in large boulders. At points in the
ravine where the soil is deep alluvium there is a local development
of ash and alder woodland, grading to ash-oak on drier ground.
Within this woodland there are a number of mature trees, some
planted exotics and a local spread of rhododendron. The sandrock
outcrops, which are the most extensive, sheltered exposures of the
formation, have the richest development of the associated
communities of
Hymenophyllum tunbrigense and suboceanic bryophytes,
Dicranum scottianum, Orthodontium gracile, Tetraphis browniana,
Bazzania trilobata, Scapaniagracilis, Pallavicinia lyellii,
Harpanthus scutatus, Blepharostoma trichophyllum, Scapania umbrosa,
Odontoschisma denudatum, Tritomaria exsectiformis and Lepidozia
sylvatica.
Wakehurst Woods are part
of one of the most extensive stands of High
Weald gill woodland with one of the largest sandrock outcrops. Much
of the woodland is oak or oak-beech mixture, mature but with few
really ancient trees, but along springlines alder and ash woodland
occurs. Woodland types occurring in small quantity are open woodland
of birch and oak, and areas of coppice, principally of sweet
chestnut and hazel on lower slopes. At the higher levels bracken,
bilberry, Deschampsia flexuosa and Lonicera peri-clymenum dominate
the ground flora; whilst at lower levels on the clays, bramble,
primrose, bluebell and wood anemone are prevalent, and flush
communities with Carex laevigata and Chrysosplenium oppositifolium
occur with the alder. The epiphytic lichen flora is moderately rich,
but includes no exceptional occurrences. The ground flora includes
Dryop-teris aemula and Wahlenbergia hederacea. The most important
feature is the community of the sandrock outcrop, second only to
those in Chiddingly Wood, which includes Hymenophyllum tunbrigense
and a number of rare bryophytes and saxicolous lichens.
At their nearest point
these two woods are no more than 200 m apart.
Collectively they form easily the richest of the sandrock
communities. The two sites complement each other in that some of the
characteristic species absent in Chiddingly are present in
Wakehurst, and vice versa. In neither case are the tree and shrub
strata of particular importance, except that the continuity of a
substantial tract of high forest with few large clearings is
essential for the continued existence of the sandrock communities.
W.I3- THE MENS AND
THE CUT AND BEDHAM ESCARPMENT, SUSSEX
TQ 0223. I9° na
Grade i
This extensive common woodland
lies along the parish boundaries of
Kirdford and Fittleworth from Idehurst Hurst to the Bedham
Escarpment. For the most part it is on flat, low-lying ground
drained by the headwaters of the River Arun, but at the south- west
end it rises to a small hill. This is where the sandy Hythe Beds
outcrop above Ather-field Clay, and give rise to acidic, sandy soils
which are nevertheless imperfectly drained. Most of the site lies on
Lower Weald Clay, but through Hammonds Wood there are numerous
sandstone bands, and Paludina Limestone outcrops in a narrow band
across The Cut.
The woodland is mostly
high forest of sessile and pedunculate oaks,
beech and locally ash, wild service and the birches. There is a
tendency for beech to be dominant over a holly or yew understorey on
the lighter soils, and for oaks and ash to be dominant over a mixed
shrub layer on the heavy soils. A few ancient oaks are present, but
most of the trees are probably less than 100 years old. Even so, the
structure of the wood is one of its important features, for all
stages of the regeneration cycle are well represented. The ground
vegetation is limited for a site of this size, but many
characteristic woodland species are present, including Carex
pendula, C. strigosa and Milium effusum. There is a moderately rich
bryophyte flora which includes, at the Bedham end, a number of local
species on small boulders, Campylostelium saxicola, Brachydontium
trichoides, Mar-supella emarginata and M. ustulata. The epiphytic
lichen flora is not fully known, but is certainly among the richest
for woodland in the south- east. Recent detailed examination of the
fungal flora has revealed that, in this respect, The Mens and The
Cut is one of the richest woods in Britain, and may even be the
richest: included in the list are three Russula spp. not known
elsewhere in Britain, and another two known only from one or two
other sites. Entomologic-ally, this site is regarded as extremely
rich, especially in the Crimbourne Wood area, with many extremely
rare beetles on record and thriving populations of most of the
woodland butterflies.
W.I4- FAIRLIGHT,
ECCLESBOURNE AND WARREN GLENS, SUSSEX
TQ 8511.
205 ha
Grade i
The Lower Cretaceous rocks
of the Weald are exposed along this
stretch of coast. Magnificent cliff sections include the Fairlight
Clays (type locality), Ashdown Sand and Wadhurst Clay. Considerable
slipping and erosion has occurred creating a distinct undercliff
zone which is heavily overgrown with scrub. Isolated boulders in
this zone support a number of interesting bryophytes including
Tortula cuneifolia, T. marginata, Desmatodon convolutus and
Lophocolea fragrans in its only station east of Dorset.
The three glens have been
cut down through the Wad-hurst Clay,
Ashdown Sand and in the case of Fairlight and Warren Glens through
the Fairlight Clays as well. The valleys produced have steep sides
covered in parts with mature woodland consisting of oak, beech, and
ash with yew, holly, field maple, birch and alder which grade into a
coastal scrub towards the cliff edge consisting of wind-pruned
thickets of privet and blackthorn. The ground flora varies from
bracken-dominated communities on the sands, to communities of
Mercurialis perennis with Carex pendula and Epipactis purpurata on
the clays. Flush communities with for example Chrysosplenium
oppositifolium and Allium ursinum occur with the alder.
Floristically, Fairlight
Glen is of considerable importance for the
presence of the rare hepatic Dumortiera hirsuta and the moss
Fissidens rivularis in their only stations east of Devon and a
number of lichen species characteristic of old forest, e.g.
Normandina pukhella, Dimerella lutea and Graphina anguina. Its
coastal situation is rare in lowland English woods.
The area known as the Fire
Hills was at one time covered with a low
growing heath community of Calluna vulgaris and Erica cinerea; this
has now been largely replaced by Ulex emopaeus.
W.I5- WORMLEY
WOOD-HODDESDON PARK WOOD, HERTFORDSHIRE
TL 3306. 570 ha
Grade i
The site is a series of
contiguous woods which include in the west
Wormley Wood and in the east Hoddesdon Park Wood. Much of the
intervening woodland has been recently felled and replanted with
conifers but broad-leaved trees and patches of broad- leaved
woodland still occur throughout. Part of the outstanding interest of
the area lies in its large extent, which provides for a greater
variety of woodland habitats and also for areas of scrub and rough
grassland.
Wormley Wood lies mainly
on the London Clay but there are also
gravel deposits. The varied geology and former land-use have
produced a mosaic of vegetation. Sessile oak is the principal
standard species over a coppice of almost pure hornbeam, but there
is a proportion of other tree species including ash, pedunculate oak
and birch. There are also some areas of high forest structure with
standards of both oak and hornbeam. The ground flora consists
largely of communities dominated by bramble, wood anemone, bluebell,
Luzula sylvatica and Lonicera periclymenum with bryophyte carpets of
Dicranum majus on fairly acid areas under standards. On more
calcareous areas the field layer is richer with Galium odoratum,
Galeobdolon luteum, Mercurialis perennis and Carex pendula: such
areas tend to have a high proportion of ash in the canopy. Within
the site there are areas of hawthorn and blackthorn scrub and
birchwood on old field sites. The wood is crossed by a small stream
along which alder has developed.
Hoddesdon Park Wood is
mainly high forest although there are areas
of coppice. The oak is well grown and there is a wide range of
sizes, including oak saplings and seedlings. Indeed the abundance of
oak regeneration throughout this woodland complex is one of its
interesting features. The more open canopy produces a ground flora
richer in species of both vascular plants and bryophytes than the
dense coppice areas. There is also a good variety of epiphytic
species including a community of Dicranum spp. (montanum, flagellare
and strictum) which occurs on the Continent.
W.l6. ELLENDEN WOOD,
KENT
TR 1062.
100 ha
Grade 2
Ellenden Wood is part of
the ancient Blean Woods lying on London
Clay and spreads of gravel drift. Within the one block of woodland
are a number of woodland types. Coppice-with-standards of sessile
oak, with rowan, holly and wild service occurs over a field layer
dominated by Luzula sylvatica and Melampyrumpratense. Parts have
been planted with sweet chestnut, managed as coppice. A small
plateau area of clays has blackthorn, hornbeam and hazel with a
neutral ground flora. Hornbeam coppice with some oak standards (both
species) occurs on another area of clay with a predominantly
calcicolous ground flora. Valley sides have local woodland types,
including high forest of oak and beech, and of small-leaved elm, ash
and crab apple. Taken as a whole the flora is extremely rich, with a
wide ecological range, including heather and Galeobdolon luteum.
This site is close to and
comparable with Blean Wood. Botanically,
there is probably little to choose between the two, but Blean Wood
is better known zoologically and is therefore chosen as the grade I
site.
W.iy. ASHBURNHAM
PARK, SUSSEX

Grade 2
Ashburnham is a former
mediaeval deer park lying on Tunbridge Wells
Sandstone and Wadhurst Clay, much of which is now arable. The
woodland is of two types, (i) closed, high forest of oak, beech,
birch and holly with planted sweet chestnut, and (2) very old, open
oak-beech woodland. Both types are overmature and contain a rich
assemblage of epiphytic lichens, second only to those in Bridge
Park, including species characteristically on holly which are not so
well developed east of the New Forest. The ground flora is limited,
but includes Dryopteris aemula on sandstone. In its general
character and many other features this site is similar to the
ancient oak-beech- holly woods of the New Forest.
W.l8. PARHAM
PARK, SUSSEX
TQ 0514.
280 ha
Grade 2
Parham Park lies on Folkestone
Sands at the foot of the South Downs.
It is a mediaeval deer park which still contains deer. Parts of the
woodland comprise open forest of huge, ancient oaks, probably the
best remaining stand of overmature oaks in south-east England. North
Park Wood is closed canopy high forest of beech and oak with an
under -storey of holly. Despite the presence of sheltered valleys,
the vascular flora is very limited, but the epiflora is richer than
all other sites in the south-east except Bridge Park and Ashburnham
Park. Among the 103 lichen species are Thelopsis rubella and
Ophegrapha rufescens, known nowhere else east of the New Forest.
W.I9- STAFFHURST
WOOD, SURREY
TQ 4148.
50 ha
Grade 2
Staffhurst is a former
common woodland lying on Weald Clay.
Structurally it is very irregular coppice-with-standards in which
cutting has been sporadic rather than systematic. The dominant
species, pedunculate oak, beech and hornbeam, all occur as
standards, but only the latter two have been coppiced. The shrub
layer, in addition to the coppice species, contains holly and yew.
Throughout the wood the ground flora is dominated by bramble,
bracken and bluebell. Two subsidiary woodland types also occur. On
the western side is a small area of open woodland of ancient oaks
and yew, with a number of epiphytic lichens. On low-lying base-rich
and partly flushed areas a mixed deciduous woodland with oak,
hornbeam, ash, field maple and wild service occurs over a ground
flora including Brachypodium sylva-ticum, Mercurialis perennis,
Primula vulgaris and Sanicuia ewopaea, with the local sedge Carex
strigosa. Marginal to the Staffhurst Common is Butcherswood Bank, a
small area of hazel and hornbeam coppice with oak and birch as
standards.
Taken as a whole, this
wood is important as one of the few woods
with a wide range of structural types and age classes, associated
with a range of field layer communities.
W.20. COLTERS
HANGER, SURREY
TQ 0448.
35 ha
Grade 2
This wood occupies a south-facing
slope running down to the River
Tillingbourne. Like Scords Wood it has a range of woodland types
zoned on this slope to correspond with marked differences in soil
nutrient status and water content. The highest zone over dry, sandy
soil is oak woodland over a field layer dominated by bracken. The
intermediate zone is mixed deciduous woodland of oak standards and
hazel coppice with wych elm, ash and field maple over a basi-philous
ground flora including Mercurialis perennis, Adoxa moschatellina and
Campanula trachelium. On a springline below is alder woodland
containing Chrysosplenium oppositi-folium, C. alternifolium,
Equisetum telmateia and Cardamine amara.
This site is selected partly
to represent eutrophic alder carr in
the south-east, where it is particularly characteristic of
springlines and the floors of gills and valleys. It is, however,
preferred to other, more extensive alder carrs in the district (e.g.
at Iping) because of the diversity of woodland types present,
related to geological diversity in the escarpment at different
levels.
W.2i. GLOVER'S WOOD, SURREY
TQ 2240.
95 ha
Grade 2
This is a substantial wood
which lies on neutral and mildly acid
clays across the incised valley of the Welland Gill. Two main
woodland types may be distinguished. On the steep-sided gill there
is hornbeam coppice with a limited proportion of ash, wych elm,
maple, hazel and small-leaved lime, and a ground flora with
Galeobdolon luteum, Endymion non-scriptus, Rubus-Section Sylvatici
and patches of Mercurialis perennis. This woodland appears to be
primary, and can be distinguished from the plateau woodland which
has developed in the last century or more on abandoned fields. Much
of the plateau woodland is of birch, hazel and pedunculate oak, but
numerous other tree and shrub species are present, including
hornbeam, which is now invading from the former hedgerows. The
ground flora is mainly .Rates- Section Sylvatici, honeysuckle
and small patches of bracken.
This site is one of many
in the Weald with a mixture of primary and
secondary woodland, and relatively uniform coppices. It is selected
partly because of its large size and also because it has small
populations of lime and wych elm which are rare in the Weald.

W.22. BRADENHAM
WOODS, BUCKINGHAMSHIRE
SU8397. 180 ha Grade
i The Bradenham Woods are examples of plateau
and dip slope Chiltern woodlands, comprised of the three almost
contiguous Naphill, Bradenham and Park Woods. As a group they are
believed to be the best example of this type in the Chilterns.
Naphill Common is an oak
(Quercus robur and Q. petraea)-beech
woodland with some birch. Holly and cherry also reach the canopy
though they are more frequently present in the understorey with
elder, willow, whitebeam, rowan and yew. Bramble with wood sorrel,
bracken and honeysuckle are abundant in the field layer and heather,
unusual in this area, is present in the rides. Apparently in the
18905 parts of this wood were open, with gorse and juniper 4.5-6 m
high.
Bradenham Wood is a well-grown
dip slope beechwood north of Naphill
Common with occasional sycamore, pedunculate oak and whitebeam. Both
beech and oak are regenerating. One area has been clear-felled
(1969) and young beech has been planted at 120 cm intervals. The
ground flora is predominantly bramble-wood sorrel though much of the
ground is litter covered. Many other calcifuge species are common,
including heather, foxglove and Potentilla erecta. A dew pond at the
summit and Sarsen pits add to the variety of habitat.
Park Wood lies north of
Bradenham and is separated from it by an RAF
housing estate. A small area of scrub grassland, managed by the
Berkshire, Buckinghamshire and Oxfordshire Naturalists' Trust, is at
the north-west corner. The beech woodland is richer in shrub and
herbaceous species than Bradenham and regeneration of both beech and
pedunculate oak is taking place. Other canopy species present are
sycamore, ash and yew, The trees, at 160 years, are some of the
oldest in the Chilterns. Shrub species include field maple,
clematis, hazel, holly, privet, gean, willow, wayfaring tree and
guelder rose. The field layer consists mainly of Galeobdolon luteum-
Geranium robertianum-Rubus fruti-cosusMercurialis perennis-Sanicula
europaea with sheets of ivy in places.
W.23- WINDSOR FOREST,
BERKSHIRE
su 9373.
710 ha
Grade i
An area of 3150 ha of Windsor
Forest is managed commercially by the
Crown Estate. Of this, approximately 1200 ha consists mainly of oak
woodland or mixed woodland in which the oak complement will be
progressively enhanced by thinning. At High Standing Hill 18 ha of
unmanaged woodland contain oak and overmature beech in the best
surviving piece of the original Forest. This extends farther west on
either side of a stream valley where remnants of old beech-oak
woodland predominate with an epiphytic lichen flora of 58 species,
including some old-forest relics. The ancient oaks of The Parks have
a number of other lichen species. Although the ground flora tends to
be poor on the Bagshot Sands such areas have proved outstanding for
oak regeneration.
Windsor Forest probably
ranks second only to the New Forest with
regard to the richness of its insect fauna. It is particularly noted
for many rare beetles associated with the old oaks and Donisthorpe
(1939) published an impressive list. With more recent additions the
total number of Coleoptera recorded from the forest must number
close on 2000
species. Some very rare beetles are known in this
country only from the Windsor and Sherwood Forests. With the
destruction of most of the latter, species such as Teredus
cylindricus and Cryptocephalus querceti may only be able to survive
in Windsor. Although individual entomologists would probably
nominate particular areas as outstanding from their particular
specialist point of view, it is the size of the Forest as a whole,
forming a nucleus within a much larger area of well-wooded
countryside, that is of paramount importance. The maintenance of the
high entomological importance of this area depends on sufficient oak
and beech trees being allowed to become overmature, die, and rot in
situ, as is the present management practice.
W.24- WYCHWOOD
FOREST, OXFORDSHIRE
SP 3316.
261 ha
Grade i
This large block of woodland
was formerly a Royal Forest,
disafforested as late as 1858. It is a complex area ecologically,
this complexity arising first from the variety of soil types derived
from the limestone, clays, marls, sands and siliceous drifts on
which it lies, and also from differences in management. Much, if not
all, of the woods were managed as coppice-with-standards but this
has now largely disappeared and the old coppice boundaries have been
obscured by more recent developments. Parts of the woodland are now
oak-wood with a proportion of ash, but large areas are dominated by
hawthorn (both species and hybrids). Many other types of scrub
occur, including blackthorn, willow, field maple and elder, the
existence of which appears to be a direct result of different forms
of management. Numerous exotic species of both soft and hard woods
have been introduced in recent decades. Floristically, Wychwood is
fairly rich, the variety of ground flora communities reflecting not
only the variety of soils and tree cover, but also the presence of
glades. It is an important site for the lichens of old woodland. The
small marl ponds within the forest are given grade 2 for their open
water interest (OW.n). (See Appendix.)
W.25- WATERPERRY WOOD,
OXFORDSHIRE
SP 6009, SP 6008.
135 ha
Grade i
Waterperry Wood is part
of Bernwood Forest where extensive insect
records go back for 100 years or more. Bernwood Forest is famous for
its Lepidoptera, which include rarities such as the purple emperor
and black hairstreak butterflies. Waterperry is a deciduous high
forest lying on gently sloping land on an outcrop of Oxford Clay,
and is dominated by pedunculate oak with ash, elm, aspen and birch.
It is similar floristically to other clay woodlands such as Monks
Wood, but it is unlikely that Monks Wood can duplicate its
entomological value. Much of it has been planted with. conifers
although a final crop of oak is planned.
W.26. NEW FOREST,
HAMPSHIRE
su 20.
12 600 ha
Grade i*
This former Royal Forest
lies on Tertiary sands, gravels and clays
dissected by wide, shallow valleys. Its soil types encompass a
considerable range from relatively base-rich brown earths to
extremely acidic podsols, and from these to waterlogged clays,
alluvium and acidic peats in flushed and low-lying situations. Only
part of this area is wooded though the woods are extensive: within
the New Forest as a whole the tracts of grassland, heathland and
valley mire grade into woodland, forming a tremendous variety of
transitional habitats of scientific importance. The woodlands
themselves are partly unenclosed, these being known as the Ancient
and Ornamental Woodlands, and managed largely for amenity and nature
conservation, and partly within enclosures: the remainder, the
Statutory Inclosures, are mostly managed commercially, but include a
number of scientifically important sites.
The woodlands are of different
types. The most extensive are mature
and overmature stands of beech, pedunculate oak, sessile oak, and
any combination of these (though it is rare to find both oaks
together), with an understorey of holly and rarely other species
such as yew and hawthorn. Structurally these are diverse, with a
range of age classes from saplings to ancient, overmature trees,
many of which have been pollarded. Over some sites on base-rich
clays, ash and less commonly field maple are important constituents,
but hazel, formerly common, is now rare within the unenclosed
woodlands. The ground flora in the woodlands on acid soils is very
poor, often no more than patchy Leucobryum glaucum, but on the
deeper soils bramble and bracken may be abundant, and on base-rich
clays a fairly rich basiphilous flora may develop.
Less extensive woodland
types fall into four broad categories. In
valley bottoms with alkaline and neutral ground water, alder carrs
have developed, some with a rich, marsh flora including Impatiens
noli-tangere and the national rarity Lud-wigia palustris: many of
these have been coppiced until recently, but there are some with a
range of age classes, including very old trees. Scrub, dominated by
holly, but also including yew, whitebeam and hawthorn, has developed
on the better, reasonably well-drained soils, and is in many places
developing into a mixed woodland with pedunculate oak dominant. Self-
sown pinewoods occur on the more heathy areas and into areas of wet
heath. Birch woodlands, though not uncommon, are found mainly around
the margins of the larger stands of mature woodland.
The vascular flora of the
New Forest woodlands is, with few
exceptions, composed of widely occurring plants. Species of
biogeographical interest in addition to the two species mentioned
above include ferns such as Thelypteris phegopteris and T. palustris
which are local in southern England. It is the cryptogamic flora of
the New Forest that is extraordinarily rich. The bryophyte flora
includes some rare species, e.g. Zygodon forsteri. In recent surveys
over 180 species of epiphytic lichens have been recorded by F. Rose,
including numerous species characteristic of ancient woodland (e.g.
Lobaria pulmonaria), oceanic species reaching their eastern limit in
the New Forest (e.g. Sticta limbata), hyper-oceanic species formerly
thought to be confined to west Scotland, Wales or western Ireland
(e.g. Mycoporellum sparsellum), boreal species not otherwise found
south of north Wales, e.g. Alectoria subcana and
Pertusaria velata which
is now apparently extinct elsewhere in
Britain.
The New Forest woodlands
are of international importance. In the
lowland areas of north-west Europe, no area equals them in extent of
old woodlands, the number of overmature trees, the relative lack of
human interference over a long period, the invertebrate fauna and
the epiphytic lichen flora. The woods are also an important breeding
area for birds, with the honey buzzard and hobby as notable rare
species. The scientific importance of the New Forest lies mainly in
the unenclosed woodlands. The enclosed woodlands, with the exception
of two areas enclosed early and still retaining their ancient
woodland, are not so rich floristically although they have some
important features (e.g. Pulmonaria longifolia and Illecebrum
verticillatum in some rides). The Ancient and Ornamental Woodlands,
and to a lesser but still significant extent the Statutory
Inclosures, support a rich invertebrate fauna which is in many
respects unique in Britain. The groups particularly well represented
are the Heteroptera, Homoptera, Lepidoptera, Hymenoptera (Aculeata
and Symphyta), Diptera and Coleoptera. The fauna of dead and dying
wood is of especial importance. Although the greatest interest
naturally attaches to the insects associated with deciduous trees,
especially oak, the fauna of the conifers, particularly Scots pine,
is by no means negligible. This is a famous area for Lepidoptera and
contains the only British localities for the interesting insect
Cicadetta Montana.
The scientific value of
the unenclosed and ancient woods results in
part from their great extent and variety and therefore the selection
of areas of outstanding importance within the complex must be
carried out with caution. Present knowledge indicates that the
biologically richer sites within the complex include Vinney Ridge,
Mark Ash, Eyeworth Wood, Rufus Stone, Hollands Wood, Whitley Wood,
Denny Wood, Mallerd Wood, Linwood, Bramshaw Wood, and South Bentley
Inclosure.

W.27- SELBORNE
HANGER, HAMPSHIRE
su 7333. 95 ha
Grade i
Selborne Hanger lies on
the north-east-facing Chalk scarp
overlooking the western limits of the Weald. It consists of a pure
beechwood on a steep east-facing Chalk slope grading to Clay-with-
Flints on a plateau with a more mixed woodland. The beech is of
uniform age and 30 m tall, with a poorly developed shrub layer of
hazel and yew. The most abundant plants are dog's mercury, ivy and
bramble, with Sanicula europaea and Brachypodium sylvaticum locally
abundant. The plateau is wooded common land with oak and ash, hazel
and hawthorn over a field layer of Rubus fruticosus-Galeobdolon
luteum. (Selborne Hanger is associated with Gilbert White.)
Selborne Hanger should
be considered with Noar Hill (L-5o) and High
Wood Hangers. These are not contiguous with Selborne but lie on the
Chalk scarp about a kilometre to the south. Within this beechwood
there is almost a complete range of aspects. The beech is uneven
aged, but casts a dense shade which has allowed only local
development of an understorey. Here yew is common, but many species
are confined to the wood margin. Mercurialis perennis, Sanicula
europaea, Galium odoratum and Hedera helix are the most abundant
field layer species.
Noar Hill has the advantage
that it is adjacent to floristi-cally
rich chalk grassland, whereas Selborne has the additional plateau
woodland feature.

on coarse gravelly sands derived from Reading Beds and areas of
superimposed plateau gravel. Structurally the woods are very diverse
with ancient pollards, closed stands of younger but mature woodland,
old coppice and scrub by open grassland. Beech is the most abundant
species, with pedunculate oak, birch and holly also locally
abundant. The field layer is sparse, with mainly calcifuge species
such as Deschampsia flexuosa, Luzula pilosa, bracken and in open
areas heather and other heathland species. Although it is so close
to London, it retains a moderately rich epiphytic lichen flora,
including Graphis elegans and Thelotrema lepadinum. The rare moss
Zygodon forsteri is also recorded. This wood has similarities to the
New Forest, but differs structurally and is inferior in extent,
diversity and floristics and so is not an alternative site.

Grove Wood is a scarp woodland
dominated by tall vigorous beech. It
appears to be even aged (123-169 years), and below gaps in the
canopy there is a field layer of dog's mercury. Ash, sycamore and
some beech regeneration occurs. Small groups of ash and one of
common elm are present, Salix capraea is abundant in some wet sites
and whitebeam is occasional in the canopy. Mature sycamore is absent
but regeneration of this species is profuse in places. The shrub
layer is not prominent and locally is lacking altogether. It
consists of characteristic chalkland species such as elder, broom,
buckthorn, hazel, box, field maple and whitebeam.
Upper Grove Wood lies on
the plateau and, though pedunculate oak is
the commonest species, the canopy contains frequent ash and beech
with coppiced small-leaved lime, gean, hornbeam and hawthorn.
Saplings of all these species, except oak, are present: Paris
quadrifolia grows here.
Aston Wood forms a curving
rectangular block facing north-west, to
the south of and above the A4O trunk road. It is contiguous with the
present NNR. Beech (90-150 years old) dominates the western two-
thirds, but a number of other species share the canopy. Oak,
whitebeam, sycamore and hornbeam are rare but ash and gean are
locally abundant, filling in gaps left by selective felling. In
addition to ash and gean, beech, sycamore and elder saplings are
present, and some of the young beech is now 20-25 years old. Holly,
hawthorn and elder form a sparse understorey
with rowan and hazel coppice
stools in a depression at the eastern
end. The eastern one-third of Aston Wood is dominated by ash, though
beech occurs frequently and oak is abundant. Mixed with these are a
few sycamore, gean, Norway spruce, elder, holly and large coppiced
rowans. The boundary between the two parts of Aston Wood is marked
by three large lime stools and a number of young trees.
On a narrow strip of sloping
ground between the A4O and the old sunk
way down the escarpment, lies a woodland of great ecological
diversity. Beech and numerous pole ash form the canopy with some
sycamore, and there is a thicket of blackthorn, a group of poorly
grown larch, a group of common elm and poplar. There is some sapling
horse chestnut, whitebeam and a stand of large field maple and
shrubs include dogwood, wayfaring tree, hawthorn and elder.
Kingston Wood, one the
largest woods in the area, extends down the
scarp slope from the plateau. Beech dominates the plateau woodland
but pedunculate oak is frequent and ash occasional. Regeneration of
beech, ash, bird cherry and willow is taking place in the gaps.
Sycamore invasion is at present being discouraged. In contrast, much
of the scarp woodland is pure beech, forming large areas of unbroken
canopy, therefore excluding both the shrub layer and regeneration.
Crowell Hill Wood is virtually a pure beech-wood and on the whole
not of outstanding interest though it contains a number of chalkland
herbs, notably Ophrys insectifera and Epipactis purpurata.
Crowell Wood is a large
block of woodland, most of which is situated
on a north-east-facing dip slope. Beech is dominant throughout but
occasional ash, oak and cherry share the canopy. Drastic thinning
occurred during the First World War and probably resulted in the
dense growth of bramble which covers the ground and may have
prevented immediate regeneration.
High Wood is another dip
slope woodland dominated by beech but,
unlike Crowell, bramble is rare in the ground flora and the canopy
is very dense. Ash is occasional and oak occurs on the upper areas.
Elder forms a sparse understorey.

Savernake was one of the
ancient Royal Forests, and is largely
managed commercially. Most of the area lies on Clay-with-Flints. The
woodland is open pedunculate oak, with numerous huge and ancient
trees, which has recently been interplanted with oak. As in most
ancient parkland woods the ground flora is limited, but the
epiphytic lichen flora is outstandingly rich, over 100 species
having been recorded recently by F. Rose. It includes species of a
more continental distribution than are found in the more coastal New
Forest, e.g. Caloplaca herbidella. Amongst the bryo-phytes are the
local species Pterogonium gracile and Dicranum montanum.
Though this site is of
less importance than the New Forest, the
average age of its oaks is considerably greater and the epiphytes
are less oceanic.

Wiltshire-Dorset county boundary. Within this the Rushmore Park
Estate comprises a large wooded plateau area and slopes leading down
to chalk grassland in the valley. The woodland includes what may be
the largest remaining area of worked hazel coppice, with pedunculate
oak and some ash and maple standards. On the plateau Clay-with-
Flints soil there is high forest of pedunculate oak and some beech.
In the valley, grading into open grassland, is closed woodland of
ash and field maple with some pedunculate oak, beech, yew and holly
and some coppiced hazel. The ground flora throughout is rich with
abundant Mercurialisperennis, Sanicula europaea and Galium odoratum.
The ash- maple woodland is notable for epiphytes, with abundant
Viscum album and the local cryptogams Leptodon smithii, Lobaria
pulmonaria and Sticta limbata.

(a) Hintlesham and Ramsey
Woods TM 0743. 80 ha
(b) Wolves Wood TM
0544. 40 ha
Grade 1
These distinct woodlands
are separated by less than 0.5 km of arable
land and as they are complementary they have been considered as a
single aggregate site. The larger wood is a complex of two ancient
woods, Hintlesham and Ramsey, and secondary woodland of various
dates surrounding and linking the two ancient nuclei. Wolves Wood is
likewise mainly
ancient woodland with some secondary extensions,
which probably include the small Keeble's
Grove, continuous with
Wolves Wood.
These woods lie on boulder
clay of a lighter and less chalky type
than is found in the east Midlands and western parts of East Anglia.
The clay soil is mainly neutral or mildly acidic with only small
areas of a calcareous nature. Much of the woodland is the oak-hazel-
birch combination with much ash on the wetter sites, but the
heavier, neutral or slightly calcareous soils have relatively little
birch and some maple. Other calcifuge coppice types occur, notably
lime coppice in Hintlesham Wood and hornbeam coppice mainly in
Wolves Wood. Part of Wolves Wood occupies a basin situation in which
the water table is high and aspen and willows are abundant in the
coppice. In addition there is a series of secondary elm woodland in
the Hintlesham part, and a series of elm coppice types in the
ancient parts of Wolves Wood, some of which have apparently invaded
other coppice types whilst others are evidently non-invasive and of
local origin. There is a range of ground flora communities
corresponding with the wide range of edaphic conditions, which
includes a number of local woodland species such as Paris
quadrifolia and Helleborus viridis.
These woods have an unusually
complex system of earthworks and
apparently have a good historical record. Only Ramsey is a complete
ancient wood, but a substantial portion of the other ancient woods
have survived. All the existing woodland is semi-natural. Many
primary woods or parts thereof survive in east Suffolk, and a
proportion of them have been examined in detail recently, but none
has been found which surpasses these two as examples of the coppice
types on the lighter glacial deposits.
W-34- STAVERTON PARK, SUFFOLK
TM 3550.
85 ha.
Grade i
This site lies on freely
drained, glacial sands wholly within the
boundary of a former mediaeval park. Documentary evidence suggests
that this is one of the few sites on the Suffolk Sandlings which
contains primary woodland. This is supported by the absence of a
podsol profile in an area where such soils are widespread following
woodland clearance, and by the presence'of a rich assemblage of
corticolous and lignicolous lichens.
The existing woods are
in two parts. The Park is occupied by open
woodland of ancient pollarded oaks (Quercus robur) and holly, with
local dominance of mature birch (both species) over a poor ground
flora dominated by bracken and Holcus mottis. The Thicks has
developed from this in the last 170 years, by an upsurge of holly,
which now forms an almost closed canopy with the oak, beneath which
ground flora is absent. Among these are some huge hollies, reaching
over 21 m in height and over 3 m in girth. Indeed, the site is
remarkable for the profusion of individuals of oak, holly birch,
rowan and hawthorn sharing the extreme forms adopted by these
species after long and vigorous growth. The only locally rare
vascular plant is Corydalis claviculata, but the epiphytic lichen
flora includes a number of rare and Atlantic species, such as
Haematomma elatinum, Lecanora cinnabarina, Thelotrema lepadinum,
Phaeographis ramificans, Stenocybe septata, Phlyctis agelaea and
Opegrapha lyncea.
In addition to the floristic
and historical interest, Staver-ton
Park and its immediate environment have a number of relatively rare
birds, such as sparrowhawk and stone curlew. The invertebrate fauna
is unknown in detail but on casual inspection appears to be rich.
W-35. FELSHAMHALL
AND MONKS PARK WOODS, SUFFOLK
TL9357- 7° ha
Grade i* Thes e two contiguous
woodlands are ancient primary
woodland which has been managed as coppice and coppice-with-
standards for many centuries, but unlike most other woods of similar
origins in East Anglia, these have been coppiced on a commercial
scale up to the present time and have thus suffered less floristic
deterioration than those sites in which the coppice cycle has been
discontinued. Felshamhall is almost certainly the demesne wood of
Bury St Edmunds Abbey and Monks Park is likewise a park given to the
Abbey in the early twelfth century.
Four main types of woodland
have been distinguished: (i) the typical
oak-ash-hazel-maple-type of the boulder clay woods; (2) a wet
variant of this, with alder and Salix alba (this feature is very
unusual); (3) an oak-birch woodland where the boulder clay gives way
to sand and sandy gravel; and (4) secondary woodland, occupying the
sites of former clearings which were the launds of the old mediaeval
park. Associated with these types are distinctive ground flora
communities and important transition types, including the Primula
elatior- Filipendula ulmaria-Mercurialis perennis association
widespread in these woods. In this site bluebell is unusually rare.
Bracken and Sarothamnm scoparius occur on the sand, and a totally
distinctive assemblage with Neottia nidus-avis marks the secondary
woodland. A total of over 280 species of vascular plants has so far
been recorded, including all the tree species of the primaeval mixed
oak forest.
Historical evidence of
woodland continuity is good. Coppicing was
practised at least as early as the thirteenth century. As in many
boulder clay woods, the oak standards were felled some time ago and
not replaced, but unusually a good natural crop of young oaks is
developing to restore the oak canopy.
The fauna is apparently
unknown, though among the birds there is an
obvious abundance of woodland warblers, but on botanical and
historical grounds alone this site is regarded as the most important
of the ancient boulder clay woods of East Anglia. Its vascular flora
is already known to be richer than almost every other wood in
eastern England. The record of its existence and management is
unusually detailed as far back as the twelfth century. As such it is
a site of both botanical and archaeological importance.

Woodland forms an important
component of the interesting habitat
complex of this Breckland site, and shows a range of types serai to
dry heath and to rich-fen. The dry parts of both heaths have a good
deal of birchwood (of both birch species), varying considerably in
stature and stocking density of the trees. There are dense thickets
and pole stands with little but litter beneath, but more open birch
growths have either bracken or heather with well-developed carpets
of the common acidophilous heath and woodland mosses. On Tuddenham
Heath, dense swards of Carex arenaria occur within the birchwoods in
places. There are scattered trees of Scots pine and oak, but though
oak seedlings are numerous on the heaths, few survive, perhaps as a
result of roe deer browsing or unfavourable soil conditions. Where
the ground becomes damper, there is a change
beneath the birch to a
field layer with Deschampsia cespitosa,
Molinia caerulea, Agrostis stolonifera and abundant Lonicera
periclymenum. There are ferns such as Dryopteris austriaca, D.
spinulosa, D. filix-mas and Athyrium filix-femina, and mosses here
include Eurhynchium praelongum, Mnium hornum, M. undulatum and
Aulacomnium androgynum. In still wetter places within the
birchwoods, there are transitions to fen communities with Phragmites
communis, Fili-pendula ulmaria, Lycopus europaeus, Mentha aquatica,
Eupatorium cannabinum, Iris pseudacorus, Urtica dioica, Equisetum
palustre and Carex acutiformis. Ash plantation probably has less ash
than formerly, as there are some large dead trees of this species,
but ash and alder are mixed with birch in the damper part of this
wood, which also has an abundance of Thelypteris palustris. Towards
the River Lark (OW.ig), the birchwoods give way to dense areas of
willow carr, mainly of Salix cinerea, which grade into open fen
communities.
W-37. SOTTERLEY PARK, SUFFOLK
TM 4685.
205 ha
Grade i
This is one of the finest
examples of the deer park habitat
remaining in East Anglia. The park is at least of early mediaeval
origin and hence may have been formed by the enclosure of more or
less primary forest. The records indicate that it was even more
wooded in the seventeenth and eighteenth centuries than it is today
but it still contains numbers of ancient oaks and areas of old
woodland.
Four main habitat types
are recognised in the park:
(i) The ornamental landscaped
garden area around the gardens of the
Hall itself with both woodland and open parkland areas containing
native trees and some exotics such as walnut.
(ii) The open parkland
north-west of the Hall with avenues and
groups of elms and ash trees, many of which are of great age, and
also some sycamore.
(iii) The areas of very
old oak woodland, or oak in open canopy in
which are also old ash trees.
(iv) Areas of enclosed
woodland largely oak but with beech,
chestnut, hazel and other trees. Of these four habitats the first
three are most important. Many of the oaks are of huge size and
great age and the epiflora is very rich. The fourth type appears
less rich but needs further study.
The epiphyte flora of 89
species of lichens and 14 bryo-phytes is
the richest known in East Anglia today for an area of comparable
size. The most notable lichens are Anaptychia ciliaris, Calicium
dbietinum, Chaenotheca brunneola, Norman-dia pulchella, Opegrapha
sonedufera, and Ramalinafraxinea. Other species found in abundance
here include Opegrapha lyncea, Rinodina roborus and Hechancha
premnea.

Alder occurs extensively

Species of Ribes (R. nigrum,
R. silvestre and R. wva-crispa) occur
and are very characteristic of this woodland type as are the
climbers Calystegia sepium, Humulus lupulus and Solanum dulcamara.
The field layer contains Carex panicu-lata, Iris pseudacorus, Urtica
dioica and Thelypteris palustris. The alder woodland here is
probably the best example of its type in Britain, showing as it does
a complete range of successional stages from open marsh, together
with floristic richness. The site has also been given grade i*
status as a peatland (P.y).
W-39- SWANTON
NOVERS WOODS, NORFOLK
TG 0131.

Grade i*
This wood straddles a geological
boundary between glacial sands and
gravels to the north and calcareous boulder clay at the southern
end. Correlated with this is the boundary between two contrasting
woodland types. On the acid sands and gravels, coppice-with-
standards with both species of oak in intimate mixture forms a
closed canopy over Pteri-dium aquilinum, Lonicera periclymenum,
Convallaria majalis and Calluna vulgaris with Teucrium scorodonia
along the rides. Mixed deciduous woodland grows over the mildly acid
and neutral boulder clay: this is coppice-with-standards with both
oak species as standards over mixed coppice of small-leaved lime,
ash, maple and willow. The ground flora here comprises Filipendula
ulmaria, Geum rivale, Ranunculus repens on the damp areas, and Mer-
curialis perennts, Endymion non-scriptus on the drier transition to
the sands. In a very wet site on the western margin a third woodland
type with oak, alder and bird-cherry exists. Floristically the site
is exceptionally rich with at least 25 native tree and shrub
species, and a number of rare and local herbs, notably Maianthemum
bifolium in what is almost certainly a native location. Many
bryophytes and epiphytic lichens have been recorded, but most of the
species are common and widespread.
Swanton Novers is undoubtedly
an important site, containing three
woodland types, each of which on its own would have been enough to
justify selection. Furthermore, the mixed coppice is still actively
worked, but a small block has been felled and replanted with
conifers. It is almost certainly a primary woodland site and as such
constitutes an important contrast with the more widespread type of
oak-ash-maple-hazel primary woodland.

Hayley Wood stands on the
Chalky Boulder Clay plateau on soil which
is heavy and waterlogged or flooded for much of the year.
Structurally it is coppice-with-standards, with both large coppice
of field maple and ash and small coppice of hazel and hawthorn below
a thin canopy of pedunculate oak standards. Small areas have been
invaded by Ulmus carpinifolia over the last 200 years. The ground
vegetation forms concentric zones from the wet middle and north,
dominated by oxlip and Filipendula ulmaria, to the drier eastern,
southern and western fringes dominated by dog's mercury. The
intermediate zones have the richest plant communities, with tracts
of bluebell and Galeobdolon luteum. The coppice plots in the wetter
area have luxuriant vegetation resembling fen communities, with
Cirsium palustre, Ranunculus flammula and Galium palustre. A number
of rare and local species occur, including Melam-pyrum cristatum,
Serratula tinctoria, Sedum telephium, Ophioglossum vulgatum and
Centaurium pulchellum. About 250 species of vascular plant have been
recorded, including 29 native tree and shrub species.
Hayley is one of the largest
of the boulder clay woods. It has
perhaps the largest single population of oxlip, and this in a site
lacking primrose. It has a rich bryophyte flora for eastern England,
notable for the inclusion of Nowellia curvifolia. It is almost
wholly an ancient wood, with a recorded history of over 700 years,
embodying the typical features of other ancient coppice woods in the
vicinity. Furthermore, it has been used for research and teaching
for many years. It is one of a number of boulder clay coppice woods
selected, which cover a range of soil types from very light (Swanton
Novers Woods), light (Hintlesham Woods) to heavy (Hayley Wood) and
transitional to fen carr (Fel-shamhall and Monks Park Woods, where
there is a range of conditions, including light soils).

The NNR of Holme Fen lies
partly on the site of the former
Whittlesey Mere. After drainage, part of the area was used for
agriculture and later abandoned. Since then, extensive birchwoods
(both species) have developed, which now constitute the finest
development of this type of woodland in lowland Britain. Other tree
species are present (oak, alder, willow and pine) in some areas, but
in general the birch woodland is remarkably pure. Another feature,
which is particularly valuable for experimental research, is the
fact that stands of different ages are present, covering almost the
entire life span of birch.
The area is additionally
interesting as a relict location of raised
mire species, including Sphagnum sp. and Calluna vulgaris. A recent
survey has shown that Holme Fen is exceptionally rich in fungus
species, including Naucoria langei which has been added to the
British list.
Excavations for a new pond
to supplement the existing duck decoy are
well advanced. When completed this will be an important feature of
the reserve and of the area generally.

Centred on the Oxford Clay
dip slope on the edge of the Fens, Monks
Wood embodies the typical features of ancient woodlands of the
Huntingdon area. It is predominantly an ash-pedunculate oak wood
with local dominance of elm. It has been managed as coppice-with-
standards, but in recent decades the system fell into neglect and
the big timber was largely extracted and not replaced. A wide range
of tree and shrub species occurs, including maple, aspen, wild
service, birch
(both species), hawthorn (both species and hybrids),
many willows, hazel, guelder rose, wayfaring tree, spindle, privet,
blackthorn and dogwood. The ground flora is extremely rich, ranging
from dog's mercury on the well-drained sites to Filipendula ulmaria
on the waterlogged areas, and diversified by the presence of rides,
streams, ponds, overgrown old fields and small glades. Oxlip is
absent although primrose is common: Monks Wood is evidently just
outside the tolerance of oxlip. Recently, the management has
partially restored the coppicing cycle, and with it the herb
richness associated with the years following cutting. In addition to
its floristic richness, Monks Wood has long been famous
entomologically. Among the species for which it is noted is the
black hairstreak Strymonidia pruni, which was first collected here
in Britain, but the purple emperor has not been seen for some years.
In certain years there is a large breeding population of woodcock,
and the wood is still a good locality for the nightingale.

The royal forest of Rockingham
once comprised an extensive tract of
semi-natural coppices, some of which were in large, continuous woods
many thousands of hectares in extent. These have now been fragmented
by clearance and opencast mining, and most of the surviving woods
have been converted to plantations. Of the remaining stands of semi-
natural woodland, only the former Purlieu Woods at the north-eastern
extremity of the forest are of outstanding importance. These formed
one continuous woodland until the mid nineteenth century when the
clearance of the western half of Thornhaw Woods cut the woods into
two main blocks, Bedford Purlieus to the east and Easton Hornstocks
to the west.
These woods lie mainly
on Jurassic limestone covered in places by
clay drift with patches of sand. Thus, although the soils tend to be
calcareous and poorly drained, there are appreciable areas of freely
drained soils of a variety of texture, and some tracts of acidic,
sandy soils. The coppice in consequence includes a wide range of
types including lime coppice on soils which are appreciably more
calcareous than most of its eastern locations, ash, hazel, wych elm,
maple coppice on calcareous clays, birch and poplar groves, sessile
oak-hazel coppice on acidic sands, valley Ulmus procera woodland and
extensive areas of sycamore invasion.
Bedford Purlieus is clearly
the most important part of the group.
Structurally it is very limited, having been clear-felled in recent
decades and partly replanted. Its outstanding feature is its
assemblage of herbaceous species (over 450 species of vascular
plants have been recorded), which include Euphorbia lathyrus, a
species of national rarity, Melica nutans at the southern edge of
its range, and E. amygdaloides towards its northern limit. Within
this wood both calcicolous and calcifuge species occur together with
those found more commonly in northern and western woodlands,
including Galium odoratum, Melampyrum pratense, Platanthera
chlorantha, Allium ursinum, Conval-laria majalis, Aquilegia
vulgaris, Ophrys insectifera, Blechnum spicant, Paris quadrifolia,
Luzulasylvatica, Atropa belladonna and Serratula tinctoria. On the
grounds of this floristic richness, Bedford Purlieus has been
described as one of the most important woods in Britain.
The fauna is also rich,
and although it is still relatively unknown,
it is regarded as the richest locality in this part of the east
Midlands. Among the butterflies recorded are the white admiral,
pearl- bordered fritillary, the silver washed fritillary, the dark
green fritillary, high brown fritillary, chequered skipper, brown
hairstreak, and white-letter hairstreak. Numerous local moths have
been recorded here. It is an isolated east Midland locality for both
the palmate newt and the adder.
Coppicing has now stopped
entirely in the group. Part of Collyweston
Great Wood has become a plantation whilst the centre was cleared for
an RAF establishment. A large quarry occupies the centre of Easton
Hornstocks. Part of Wittering Coppice has been converted to a poplar
plantation. Substantial areas of Bedford Purlieus have been
replanted with oak, beech and a variety of conifers, and other
sections have been destroyed by quarrying and military needs in
wartime. Despite all this, substantial areas of semi-natural
woodland exist in all four component woods of the site.

The woodlands of Castor
Hanglands NNR straddle a zone of marked
geological variety in Jurassic rocks, ranging in north-south
sequence from limestone to clay, cornbrash, sand and then clay

loams to calcareous and neutral gleys. Most of the woodland was
formerly coppice-with-standards, most of which has been removed,
leaving a mixed ash-pedunculate oak woodland, with hazel, privet,
dogwood and spindle. On wetter soils, large ash stools occur with
hazel, willow and aspen. Part of Moore Wood, also in the reserve, is
high forest pedunculate oak. Corresponding with the soil variation,
a wide range of field layer types occur; Rubus fruticosus is locally
dominant, but Mercurialis perennis-Endymion non-scriptus is the most
widespread type, with Primula vulgaris, Anemone nemorosa, Lonicera
periclymenum and Euphorbia amygdaloides. Paris quadrifolia, Oxalis
acetosella and Allium ursinum occur on the wetter soils. The rides
and clearings are kept open and this encourages the rich
invertebrate fauna.
The woodlands are a good
example of oak-ash woodland, but their most
important feature is that they constitute part of a complex of

Newball and Hardy Gang
Woods were almost continuous until the

They both lie on clay with a covering of sand which varies from over
50 cm in depth to negligible. On the clay soils, most of which are
gleyed, there are extensive tracts of lime coppice, whilst on the
low- lying clays aspen, hazel and ash are abundant with no lime.
On the deep sands, birch scrub with bracken and Holcus mollis is
prevalent. Marginal to this, sessile oak and hazel dominate with the
birches. The soils of both woods are almost entirely strongly to
mildly acid, with small areas of heavy neutral soils notable for the
increase in abundance of calci-coles such as field maple and dog's
mercury. In Newball Wood there is a small patch of plateau alder
coppice on locally waterlogged sand, which constitutes an important
ecological line with the large fen-edge coppices near Woodhall Spa
and Tumby. Both woods appear to have been simple coppice with only
few oak standards, but the northern part of Newball has a number of
oak standards. In Hardy Gang there is a small area where pedunculate
oak is one of the main coppice species, with some large, ancient
stools. Records to date indicate that Newball Wood alone is
floristically the richest of the Lincolnshire limewoods, with Hardy
Gang only slightly less rich: their flora includes many of the local
woodland species. Furthermore, Newball is, on present evidence, the
richest limewood entomo-logically.
Both sites have been partly
felled and replanted with
conifers. The southern
part of Newball was the scene of a Forestry
Commission trial, and the small control plots of untouched coppice
are important remnants which indicate the nature of the coppice over
much of the land now under new plantations.
(c) Stain-field and Scotgrove
Woods TF 1273, TF I37°- 87 ha
Unlike other woodlands
in central Lincolnshire, the Stain-field
Woods occupy a shallow basin situation. The soils vary from sand
with a high water table to strongly gleyed and well-drained acid and
neutral clays. Much of the woodland is lime coppice but with a
variety of other species, notably the birches. The wide range of
ground flora communities extends to the Lonicera periclymenum,
Convallaria majalis, Rubus- Section Suberecti community on strongly
acidic, organic sand, and to Sphagnum where similar soils have the
water table permanently at or near the surface.
Within a short distance
of Stainfield Woods, but separated from it
by arable farmland, is Scotgrove Wood. This is a good example of
lime- oak coppice derived from oak over lime coppice-with-standards,
developed mainly on acid, poorly drained clays, which have an
appreciable sand fraction in surface horizons at the southern end.
The marginal diversity characteristic of coppice woods shows well at
Scotgrove, where wild service and wych elm are confined to the
woodland edge. A drainage line runs through the southern area, along
which mixed coppice of ash, maple, hazel occurs over a fen-like
ground flora including Carex acutiformis. The northern boundary is
marked by a massive dyke and bank, on which calcareous clay subsoil
is exposed, and a rich flora has developed, including calcareous
grassland, and mixed scrub and coppice.
Both woods have been partly
felled and replanted with conifers. The
most important areas for conservation are the western part of
Scotgrove and the sections of Stainfield known as Great South and
Demerose Woods. Of these the Stainfield part is more important for
its unusual edaphic conditions.
(d) Potterhanworth Wood ;
TF 0767. 35 ha
The western half has been
converted to conifers, but the eastern
half remains as coppice derived from coppice-with-standards, on a
site which is known to have been continuously wooded. The relatively
strong relief gives rise to both receiving sites and freely drained
slopes. Much of the wood lies on clay but a substantial tract lies
on sandy loam above the clay. Most soils are neutral, but the
textural and drainage variety is sufficient to enable a wide range
of ground flora communities to develop. Most of the coppice consists
of almost pure small-leaved lime but, towards the south, lime is
rare, ash, oak and birch being the most abundant. The particular
features of Potterhanworth are repeated to some extent in other
Lincolnshire limewoods, but in the presence of Frangula alnus,
Prunus avium and Campanula trachelium it has affinities with woods
further south and west. The Roman-built Car Dyke runs along its
eastern margin.
W-45(ii). BARDNEY
FOREST (LINCOLNSHIRE LIME-WOODS), LINCOLNSHIRE
Grade 2
(a) Great West-Cocklode-Spring
Woods TF 1076. 37 ha
Four contiguous woods occupy
a relatively low-lying area along
parish boundaries. Of these Little West, and substantial parts of
Cocklode and Great West, have been felled and replanted with
conifers. The remaining areas under lime woodland include one of the
best high forest stands (Great West); a herb-rich coppice (Spring)
in which Carex strigosa, Ophioglossum vulgatum and Myosotis
sylvatica occur; and an area of uniform coppice of high potential
research value (Cocklode), all on mainly neutral clay and sandy clay
soils. In Cocklode, outlying parts of the earthworks of Bullington
Priory extend into the wood and offer an opportunity to study the
development of the characteristic woodland. Recently some two-thirds
of Spring Wood was cleared for arable cultivation.
(b) Stainton-Fulnetby Woods'
TF 0778. 68 ha
Stainton, Fulnetby and
Rand Woods form contiguous stands, of which
Rand has been completely felled and replanted with conifers.
Stainton is typical high forest lime woodland in which lime is a
minority element through part of the wood. Fulnetby is the best
remaining stand of coppice-with-standards oak over lime, with
spindle locally common, but is floristically impoverished in
comparison with most other woods.
(c) Wickenby Wood TF 0882.
45 ha
Uniformly wet throughout,
this coppice has a variety of woodland
types, being partly dominated by lime, with areas of ash, maple and
hazel and local dominance of willow. Wickenby is one of the richer
woods floristically, and is markedly the most alkaline of all the
Lincolnshire lime-woods. As such there is a case for including it as
a grade I site, but most of its features can be found elsewhere in
grade i sites, even if they are less well-developed than at Wickenby.
W-46. BENACRE PARK, SUFFOLK
TM 5084.
135 ha
Grade 2
Benacre Park contains similar
areas of ancient oak with a rich
epiphytic flora as described for Sotterley Park, and must be
considered as an alternative to it though the two areas are close
together and complement each other. It too contains species of
lichen that are now extremely rare elsewhere in East Anglia.
W-47. FOXLEY WOOD,
NORFOLK
TG 0524. 65
ha
Grade 2
Three broad woodland types
occur in Foxley Wood. The most
widespread, on wet clay soils, is mixed deciduous in which
pedunculate oak and hazel are the most abundant, but ash, field
maple and birch are common and a number of other tree and shrub
species are present. The ground flora here is Filipendula ulmaria-
Geum rivale grading to Mercurialis perennis- Endymion non-scriptus
and Convallaria majalis on the drier areas. The 'sacred ground' near
the wood's centre is sandy, with oak high forest over a
discontinuous holly understorey and a ground flora dominated by
bracken and Holms lanatus. Thirdly, a flushed tract is occupied by
alder coppice, while alder also occurs as a constituent of coppice
on the lighter soils. Floristically, Foxley is one of the richest
woods in East Anglia: though no rare species are recorded, many are
very local, notably Myosotis sylvatica, Sedum telephium, Sorbus
torminalis, Primus padus and Carex strigosa.
Though Foxley has been
partly replanted with conifers, and the
remainder has been cleared of all worthwhile timber, the site is
nevertheless important. As an ancient coppice site, it is unusual in
possessing alder, and in some respects grades into fen woodland
(Carex lepidocarpa and Prunuspadus are present). Furthermore, this
ranges through to dry, acidophilous woodland. It is almost as
important as Swanton Novers, and in many respects is similar and is
graded as an alternative site.
W-48. WAYLAND
WOOD, NORFOLK
TL 9399.
35 ha
Grade 2
Lying on wet, calcareous
boulder clay, this is a coppice-with-
standards woodland. Pedunculate oak is the main standard which with
a few ash and birch forms a fairly open canopy. The coppice layer
contains a limited amount of ash and field maple, but is mainly a
hazel-bird-cherry mixture with dogwood, willow and groups of holly.
At a point on the margin, elm has encroached into the wood. The soil
is wet throughout, and the ground flora is mainly of the Filipendula
ulmaria type with no Mercurialis perennis. Said to be rich
floristically, this is the only site for Gagea lutea in Norfolk.
This is a good example
of a coppice-with-standards woodland still
managed as such. It is selected for this and the unusual combination
of coppice species otherwise unknown in lowland England.
W-49- SEXTON
WOOD, NORFOLK
TM 2991. 40
ha
Grade 2
Sexton Wood lies mostly
on neutral clay soils and comprises an
almost pure stand of hornbeam coppice with oak standards. Towards
the southern end the soil is almost calcareous, and here maple is
relatively abundant. Centrally there is a small, wet basin occupied
by ash and willow and a poor-fen flora. At the north end where the
soils are appreciably more sandy there is much more birch, and the
oak is dense enough to form high forest above hornbeam shrub layer.
Sexton Wood is selected
as a representative of hornbeam coppice near
its geographical limit which is still cut sporadically. Its value
for conservation is unfortunately much diminished by the state of
the rides, which are all concrete tracks. Brooke Wood, Norfolk, was
an excellent example, but it has been almost completely replanted
with conifers, and Sexton Wood may be the best remaining example.
However, the woods of south-east Norfolk are insufficiently known
and other, better examples may be found.
W-5O. FELBRIGG WOODS, NORFOLK
TG 1940.
155 ha
Grade 2
Felbrigg Great Wood and
Felbrigg Park lie on the gravels of the
Cromer End Moraine. The Great Wood is ancient beech forest, closed
over large areas, but opened locally to admit birch regeneration.
Mixed with beech are some oak and holly and these, together with the
pollarded beech, add to the similarities between this site and some
of the Wealden and New Forest woods. The ground flora is largely
composed of bryophytes, with Dicranum scoparium, Plagiothecium
undulatum, Polytrichum formosum and Leucobryum glaucum abundant.
There is a rich epiphytic flora, including Iso-thecium myosuroides
and Parmelia perlata, both rare in Norfolk.
Felbrigg Park is ancient,
open oak woodland with some old sweet
chestnut and sycamore. The pasture remains un-ploughed. The
epiphytic lichen flora is one of the richest in Norfolk, with many
old-forest species.
The site is selected primarily
as a representative of beech-woods at
the limit of their supposed native range. It is also worthy of
selection as an overmature woodland with an epiflora rich by the
standards of eastern England.
W-5i. KING'S AND BAKER'S
WOODS, BEDFORDSHIRE
SP 9229. 230
ha
Grade 2
King's Wood, together with
Baker's Wood, is the largest area of
woodland in Bedfordshire. It lies on boulder clay passing to Lower
Greensand. The sandy soils are covered by birch woodland with some
sessile oak and Scots pine over bracken and in open areas heather.
The clays on the other hand have pedunculate oak-ash woodlands in
which hornbeam is co-dominant over large areas, and some stands of
small-leaved lime. Here the ground flora is predominantly of Primula
vulgaris, Euphorbia amygdaloides, Mercurialis perennis, Galeobdolon
luteum and Lonicera peridymenum. The woods have a number of rare and
local plant species, including Convallaria majalts, Osmunda regalis,
Luzula sylvatica and Vicia sylvatica.
Although the site has been
partly damaged by development and
replanted with conifers, it remains a rich and diverse wood, and the
damage is not irreversible. Its flora and fauna are relatively well
known, and include national and regional rarities in the fungi and
Hemiptera.
W-52. HALES
WOOD, ESSEX
TL 5740.
8 ha
Grade 2
In east Cambridge, west
Suffolk and north Essex there is a series of
coppice-with-standards woodlands over an area dominated by Chalky
Boulder Clay. Hales Wood is a good example of such a woodland. The
canopy is dominated by pedunculate oak together with ash, field
maple, elm and hornbeam, the last forming an interesting link with
the concentrations of this species in the Home counties. There is a
wide range of shrub species present including hazel, hawthorn,
dogwood, blackthorn, rose, wayfaring tree and guelder rose.
The most characteristic
feature of the ground flora is an abundance
of the true oxlip. Other species dominant in the field layer include
Mercurialis perennis, Fragaria vesca, Sanicula europaea, Viola sp.
and, in the wetter patches, Filipendula ulmaria. The dewberry is
common in some parts of the wood whilst occasional small patches of
Paris quadri-folia may be found.
W.53- CANFIELD
HART WOOD, ESSEX
TL 5619.
30 ha
Grade 2
Canfield Hart Wood lies
close to Hatfield Forest on calcareous till.
It is transitional in character between the oak-ash coppice-with-
standards type widespread in eastern England, and the derived type
dominated by elm. The ground flora has abundant oxlip and where the
canopy is broken patches of grass occur. Many rare and local species
are present, including Iris foetidissima, and Campanula glomerata,
Anacamptis pyramidalis, Ophrys apifera, more characteristic of the
grassland.
The wood is selected mainly
as the southernmost population of oxlip.
This is a species on which much research has been carried out and
whose range-determining factors are not understood. This, coupled
with the wood's diversity, justifies inclusion as a grade 2.
W-54- HATFIELD
FOREST, ESSEX
TL 5320.
360 ha
Grade 2
This former Royal Forest
lies mainly on Chalky Boulder Clay with
patches of gravel exposed near low-lying ground. Large oak, hornbeam
and horse chestnut occur in the open parkland, but most of the
woodland is coppice-with-standards from which many of the standards
have been felled. Ash, hazel and field maple are now the most
abundant species, with hornbeam and field maple standards. Within
the Forest as a whole there are also ponds and streams. A wide
variety of plants occur in the area, with Epipactis purpurata and
Paris quadrifolia among the local species present.
The site is included as
an example of eastern coppices with a
composition somewhat intermediate between the hornbeam and the ash-
hazei-maple coppices. It has the additional advantage that a variety
of habitats occur in a single location.
W_55. EPPING FOREST,
ESSEX
TQ 4298.
1150 ha
Grade 2
Epping Forest stands on
London Clay overlain in places by gravel and
sands, giving rise to a mosaic of neutral and acid soils with
locally impeded drainage. Most of the woodland is ancient groves of
pollarded beech, some of coppice origin, with some pedunculate oak,
silver birch and holly. Hornbeam forms a separate woodland type with
some pedunculate oak, mainly on the lower-lying clays. Throughout
the Forest, birch and holly invade where there are gaps in the
canopy. Although the woodland is mostly overmature, all the dominant
species are regenerating sporadically, mainly on the margins of
mature woodland. The ground flora is poor, often absent completely
below beech and hornbeam, but along watercourses and beside ponds a
marsh flora has developed. Epiphytes are much reduced by air
pollution and shade.
This site represents both
beech and pedunculate oak-hornbeam
woodland but in view of pollution and public pressure the site is
not considered to merit grade i status.
W-56. OVERHALL
GROVE, CAMBRIDGESHIRE
TL 3363.
20 ha
Grade 2
This site lies on moderately
steep slopes. The soil throughout is
heavy clay, with calcareous boulder clay at high levels and neutral
or mildly acidic Kimmeridge Clay at low levels. Ulmus carpinifolia
is dominant throughout with some pedunculate oak, ash, field maple
and elder. It is probable that the wood originally had a fairly
conventional coppice-with-standards structure, with oak and elm over
ash and maple, but in recent centuries the elm has spread
vigorously. Some massive elm and oak standards remain, however, and
in its present state Overhall Grove approximates to high forest
closer than most woods in the east Midlands and western East Anglia.
The ground flora includes a vast population of oxlip and some other
woodland species, but is mostly dominated by Urtica dioica, Glechoma
hederacea, Galium aparine and Heracleum sphondylium.
Other areas of small-leaved
elm woodland are known in the area. This
one is selected partly because of its structural maturity and oxlip
population, but it also has a number of peculiar features. Within it
is an extensive field monument (the Hall of the name) and associated
earthworks which, with other information, indicates that the wood is
ancient, secondary woodland, with no primary woodland nucleus. Its
importance is increased by the selection of Hayley Wood (mainly
primary with a small, recent, secondary area) and Hardwick Wood
(primary and a succession of secondary, adjacent stands) on similar
soils and in the same area, for Overhall is a particularly fine
demonstration of the long-lasting effects of discontinuity of
woodland cover on the woodland flora.
W-57- HARDWICK
WOOD, CAMBRIDGESHIRE
TL 3557.
16 ha
Grade 2
This is an example of woodland
on Chalky Boulder Clay, in which the
ancient core is oak-ash woodland with a coppice layer of hazel, in
which oak is much more abundant than ash. Surrounding this ancient
core is secondary woodland arising at various dates from the
sixteenth century to about 1930, which includes a variety of types
with wych elm, ash and birch locally dominant. The ground flora
includes abundant oxlip and, on the wood margin, Melampyrum
cristatum and Lathyrus sylvestris. The bryophytes include the rare
Ptilidium pulcherrimum.
In a general sense, this
site is an alternative to Hayley Wood, but
it has its own features of scientific importance. Its management
history is exceptionally diverse and well documented: similar
secondary woodland series occur in other woods selected, but these
are comparatively recent(e.g. Hintlesham Woods, Suffolk). Unlike
other Cambridgeshire woods it has apparently never had a significant
tall coppice component of ash and field maple. There is a classic
primrose-oxlip hybrid situation, which can be related to the
development of the wood.
W.s8. KESTEVEN WOODS, LINCOLNSHIRE
Grade 2
The concentration of woods
in southern Lincolnshire and Rutland is
mainly dominated by pedunculate oak, ash and hazel over
predominantly calcareous clay soils. Most if not all have been
managed as coppice- with-standards. They mostly have a rich
assemblage of subordinate native tree and shrub species, including
wild service, field maple, midland hawthorn, wayfaring tree, gean
and aspen. The ground flora is usually dominated by mixtures
including dog's mercury, Sanicula europaea, primrose, bluebell, wood
anemone and bramble, but a number of local species are found,
including Milium effusum, Sedum telephium, Epi-pactis helleborine,
Carex strigosa and Dipsacus pilosus.
As a group they have both
similarities with and fundamental
differences from the Bardney Forest woods (W-45). They had a similar
development and their range of coppice types overlap to some extent,
but the Kesteven Woods have mainly calcareous soils and,
correspondingly, limewood is relatively rare and calcicolous species
such as Campanula trachelium are more abundant. Here, as in Bardney,
the full range of variation is represented in a number of small
woods, the differences between which yield information on the
effects of management. The Kesteven Woods are placed in grade 2, but
they are not regarded as a substitute as a group for the Bardney
Forest woods.
The Kesteven Woods have
not been surveyed in detail and the
selection within them is extremely tentative. Further survey may
reveal other sites which merit grade 2 status, either in addition to
those selected, or more likely as replacements for them. In
particular, Tortoiseshell Wood is a good example of calcareous
coppice with an excellent structure, with large numbers of well-
grown standard oaks and some magnificent standard wild service trees.
(a) Dole Wood
TF 0916.
5 ha
This is a small, coppice-with-standards
wood of oak, hazel and ash,
with abundant midland hawthorn, and small areas of lime and elm. The
ground flora ranges to mildly acid communities with Holcus mollis,
Teucrium scorodonia and Lonicera periclymenum.
(b) Dunsby Wood
TF 0826.
60 ha
Formerly this was coppice-with-standards,
but most of the oak
standards have been removed and the coppice has been allowed to grow
up. The canopy is now mainly ash and field maple, with birch, aspen,
gean and patches of invasive English elm. In the shrub layer, hazel,
midland hawthorn, crab apple, and wild service are locally abundant.
The ground flora includes Dipsacus pilosus and Carex strigosa.
(c) Kirton Wood
TF 9832.
30 ha
Kirton Wood still possesses
its coppice-with-standards structure,
but the coppice ash has now become rather overgrown. Small-leaved
lime is abundant in parts. The ground flora is predominantly
calcicole, with abundant Filipendula ulmaria, Geum rivale and
Valeriana officinalis.
(d) Sapperton-Pickworth
Woods
TF 0334.
25 ha
Although formerly one wood,
this has now been divided by partial
clearing into three separate stands. These retain a good quality oak-
ash coppice-with-standards structure with local blackthorn
thickets. Parts of the wood are invaded by English elm. The ground
flora includes Campanula trachelium.

The Low Peak of Derbyshire
contains one of the most important masses
of Carboniferous Limestone in Britain. In the river valleys or Dales
coming from this area are a series of ashwoods occurring on steep
hillsides over a thin rendzina soil or on scree. These woodlands
together with those of the Mendip Hills exhibit the best-known
development of ashwood. The areas are for the most part ungrazed and
have a rich shrub and field layer. A series of woodlands is listed
in order to cover the range of variation; these areas are also
associated with key grassland sites. Historical documentation
indicates that the bulk of the woodland in the Dales area has
originated since the middle of the seventeenth century.
(a) Lathkill Dale SK 1865.
70 ha
Lathkill Dale is orientated
east-west and lies just south of
Bakewell. Some woodland on the north and east end has been modified
by planting but the remainder of the area contains some fine
ashwood. Species found with the ash include wych elm, hazel, privet,
guelder rose, field maple, elder, hawthorn, dog rose, gooseberry and
rowan. The field layer is locally dominated by Mercurialis perennis
or Deschampsia cespitosa together with ferns but there is a wide
variety of forbs present including much Geum rivale, Galeobdolon
luteum, Campanula trachelium, Poa nemoralis, P. trivialis,
Brachypodium sylvaticum and Melica uniflora. A long list of
characteristic but less common species is to be found including
dogwood, Daphne mezereum, Convallaria majalis, Neottia nidus-avis,
Helleborus viridis, Gagea lutea, Litho-spermum officinale, Mycelis
muralis, Asperula odorata, Cirsium heterophyllum,Hypericumhirsutum,
Tamus communis, Euonymus europaeus, Milium effusum, Zerna ramosa and
Festuca gigantea. Occasional old lead workings add interest as the
spoil heaps support a rich flora with species such as Helianihemum
chamaecistus, Campanula glomerata, Orchis fuchsii, Minuartia verna
and Briza media. See also L. 124(1) and OW.44-
(b) Cressbrook Dale
SK 1773.

The Dale runs in a north-south
direction, is steep sided and
contains some good limestone crags. The tree canopy is of ash with a
little wych elm and a dense shrub layer of bird-cherry, field maple,
buckthorn, guelder rose and hazel. There are patches of aspen-
dominated scrub. The lower part of the Dale appears to have been
disturbed to some extent and here sycamore is more abundant. There
is some good cliff scrub with rowan, rock whitebeam, yew, small-
leaved lime and wych elm. The field layer is dominated by
Mercurialis perennis with patches of Allium ursinum and Convallaria
majalis. Melica nutans and Campanula latifolia are frequent. There
is an interesting juxtaposition of grassland and woodland in the
Dale as well as species-rich mine spoil heaps where Minuartia verna
is common. The Dale also contains the only known English locality
for the rare moss Thamnium angustifolium. It has been suggested that
the presence of small-leaved lime together with Convallaria majalis,
bird- cherry and dogwood indicates that at least a part of the area
may be primary woodland. See also L. 124(1).
(c) Dove Dale Ashwood SK
1453. 20 ha
The craggy valley of the
Dove runs north-south and has good woods on
both east and west aspects. Dovedale Wood itself is dominated by ash
with beech, holly (very local), field maple, sycamore and
pedunculate oak. It has been suggested that the wood can be regarded
as intermediate between pure ashwood and the oakwoods of western
Britain. There are areas of fine cliff woodland dominated by yew
together with Sorbus aucuparia, S. aria, S. rupicola, Prunus
spinosa, Ribes alpinum, Rosa pimpinellifolia and Crataegus monogyna.
The herbaceous flora is varied; areas near the river are dominated
by Filipendula ulmaria, Phalaris arundinacea, Veronica beccabunga
and Petasites hybridus whilst on many of the slopes Mercurialis
perennis, Geum urbanum, Brachypodium sylvaticum, Fragaria vesca and
Deschampsia cespitosa are dominant. Where the ground is broken by
outcrops and the canopy is more open a rich assemblage of forbs is
present, at times approaching a limestone grassland sward in
composition. See also L. 124(1).

Grade i
Halesend Wood lies largely
on a Silurian limestone ridge near the
northern end of the Malvern Hills. The woodland is coppice and
coppice-with-standards in which sessile oak, hazel and common lime
are the most abundant species but many other native tree and shrub
species are frequent throughout the northern half of the wood,
notably yew, wild service, field maple and ash. The southern end,
whilst retaining the mixed deciduous character to some extent, has a
high proportion of birch and ash. The ground flora is of the rich,
basiphilous type, dominated by dog's mercury, bramble, wood anemone
and bluebell, with local areas of Allium ursinum. Certain local
forbs are common, including Campanula trachelium, Platanthera
chlorantha, Lathraea squamaria and Narcissus pseudo-narcissus.
Although hybrid lime is
one of the more abundant species here, it is
intimately mixed with other tree and shrub species and occurs as
coppice and ancient pollards. This unusual condition, and a number
of old quarries, add to Halesend Wood's value as a representative of
the rich, calcicolous woodlands of the south-west Midlands.

PARK, HEREFORDSHIRE
SO 3442.
140 ha
Grade i
Moccas Park is an ancient
deer park lying on north-facing slopes of
Old Red Sandstone, with flat ground below. The lower areas are
occupied by open, ancient park woodland with pedunculate oak and
sweet chestnut growing from an old grassland sward. On the higher
slopes the woodland is less open and richer in species, including
small-leaved lime, large-leaved lime, wych elm, field maple, holly,
beech, yew and ash, with a number of ancient specimens of exotic
trees, notably horse chestnut, sweet chestnut, and sycamore. The
field layer, which is heavily grazed in places, has abundant bracken
and other species of dry, mildly acid soils, such as foxglove,
bluebell and bramble, and patches of dog's mercury. The bryophytes
and epiphytic lichens are extremely rich, over 100 species of the
latter having been recorded recently by F. Rose. The fauna has been
relatively well studied, and is outstanding for Coleoptera, three
species being known nowhere else in Britain, namely Pyrrhidium
sanguineum (Cerambycidae), Hypebaeus flavipes (Malachiidae) and
Ernoporus caucasicus (Scolytidae).
Existing information clearly
suggests that Moccas is the best
ancient park wood in the Midlands, but other sites have been so
little studied that some may be of equal merit. Furthermore, recent
ploughing and fertilising of the grassland may have damaged its
ecological value. Brampton Bryan Park (W.I24) is at least as rich in
its lichens and can be regarded in this respect as an alternative
site but its Coleoptera have not been properly studied.

Grade i
This is the steep-sided
valley of the Humber Brook, about 1.6 km
long, and cut through Old Red Sandstone. At its upper end the slopes
are boulder strewn. The sides are wooded and undisturbed and a
miniature alluvial plain bears ash-alder wood and willow carr. Ash
is the most abundant species on the valley sides but sessile oak and
elm are co-dominant in some areas. Birch, field maple and beech are
also present. Shrubs include hazel, hawthorn, elder and blackthorn.
The field layer illustrates the downwash of bases that has occurred;
and varies from a community dominated by Deschampsia cespitosa with
abundant primrose in upper, more open areas, through bluebell,
bramble or wood anemone to dog's mercury. Flushes with Chryso-
splenium oppositifolium and the rarer C. alternifolium are common.
Also of great interest are large patches of Helle-borus viridis.
Bryophytes carpet tufa springs, rock outcrops and rotting logs.
Flanking the woodland are more open areas of bracken and gorse.
This has been chosen to
represent a rich mixed deciduous woodland
type characteristic of the west Midlands. It also has a range of
wetland habitats within this small area and has the added advantage
of being undisturbed. (See Appendix.)

Wenlock Limestone occurs along the top of the ridge.
It is essentially a pedunculate
oak-lime (Tilia vulgaris, IT.
cordata, IT. platyphyllos) high forest with ash and some elm. The
site is not managed now though hazel has been coppiced in the past.
There is one area of pure cherry in all stages of development,
including some very old trees. Many other native species are present
in the canopy including field maple, silver birch, holly, crab
apple, wild service, rowan and yew, and there are shrubs such as
spindle, privet, blackthorn, dogwood and guelder rose.
The topmost part of the
site has extensive scrub woodland and here
the ground flora is extremely rich in herbs, with abundance of
Allium ursinum with Mercurialis perennis, Filipendula ulmaria, Geum
rivale and Paris quadrifolia. Orchids include Listera ovata, Orchis
mascula, Platanthera chlorantha and Epipactis helleborine. Over the
rest of the wood Oxalis acetosella, Veronica montana and Deschampsia
cespitosa are dominant but more local species such as Carex pendula,
C. strigosa, Euphorbia amygdaloides and Campanula trachelium also
occur.
Tick Wood differs both
pedologically and floristically from better
known limestone woodlands such as those of the Derbyshire Dales and
the Cotswolds. Its vegetation is typical of woods on the highly
calcareous shales of this region.

ITCHINGTON AND UFTON WOODS, WARWICKSHIRE
SP 3862.
80 ha
Grade i
These woods are situated
on a gentle north-east-facing slope, rising
to a plateau at 90-120 m, with soils which vary from medium clay to
loam. This is a fine example of oak-hazel coppice woodland that is
still managed as such. There are well grown standards of pedunculate
oak, open grown and up to 15 m in height; the coppice layer is
dominated by vigorous hazel which is coppiced in rotation, several
different age classes being present. Other shrubs are present
including hawthorn, roses, wayfaring tree and dogwood.
The ground flora may be
divided into two main types. The upper parts
of the slope and the edge of the plateau are dominated by species
such as Rubus fruticosus agg., Deschampsia cespitosa and Carex spp.
In the damper areas and along the ditches there is an abundance of
Geum rivale. On the lower slopes the soil is a rich loam and there
is a meso-philous field layer dominated by dog's mercury, bluebell
and primrose,
with occasional patches of Paris quadrifolia. There
are a number of orchids in the wood including Listera ovata,
Platanthera bifolia, Neottia nidus-avis and Epipactis helleborine.
W.I2I. WYRE FOREST,
WORCESTERSHIRE, SHROPSHIRE
so 7576. 495
ha
Grade i
Wyre Forest lies astride
the county boundary, west of the Severn, on
either side of Dowles Brook, on the varied formations of the Coal
Measures, which include sandstones, marls and conglomerates. The
soils are mainly freely drained and acidic, but local calcareous
pockets occur.
Sessile oakwood, mainly
of coppice origin, is the widespread type
but in the valleys, rich mixed deciduous woodland with wild service,
ash, elm, small-leaved lime and alder have developed. The field
layer is predominantly calci-fuge with Pteridium aquilinum,
Vaccinium myrtillus, Calluna vulgaris, Erica cinerea and Melampyrum
pratense. In the valleys, however, there is a wide variety of
habitats from moderately acidic, to basic soligenous mire with
Sphagnum spp., Molinia caerulea and Eriophorum latifolium, to
communities on drier, base-rich soils with Brachypodium sylvaticum,
Mercurialis perennis and Primula vulgaris. Within the woods many
rare and local species occur, including Cephalanthera longifolia,
Aquikgia vulgaris, Carex mantana, Convattaria majalis, Melica
nutans, Geranium sylvaticum and G. sanguineum. The whole area is
rich in bryophytes and epiphytic lichens (by comparison with the
Midlands generally), especially the Seckley Wood ravine and other
valleys. Over 320 species of fungi have been recorded here.
The forest fauna is one
of the richest in the Midlands. The mammals
include fallow deer, otter, dormouse and several species of bat, as
well as the commoner woodland species. A wide variety of woodland
and water-side birds breeds and the avifauna has been extensively
studied. Amongst the reptiles the adder is common. The insects are
outstanding for variety and number, and include some nationally rare
species. The Kentish glory and alder kitten moths are two notable
examples amongst the Lepidoptera. The rare cerambycid beetle
Strangalia nigra occurs in one of its most northerly stations, and
Wyre Forest is one of the few British localities for the terrestrial
caddis fly, Enoicylapusilla. Rare spiders and sawflies are also
recorded.
These woodlands constitute
an important meeting point of a number of
woodland features. The oaks, though mainly sessile, have characters
intermediate with pedunculate, yet the plateau woods are
structurally and floristically allied to the oak coppices of Wales.
The valley woods on the other hand have the small-leaved lime and
wild service characteristic of the southern Welsh borderlands. Local
developments of hazel, ash and dogwood over dog's mercury and
primrose on clays are reminiscent of East Anglian woods.
Floristically, too, the area is intermediate, with, for example,
Melica nutans and Geranium sylvaticum on the edge of their range.
The forest as a whole is outstanding for invertebrates and forms one
of the most important wildlife environments in the Midlands. The
most important parts are Seckley
Wood, Dowles Brook and
its tributary stream valleys, and the
coppices east of Park Brook.
W.I22. CANNOCK
CHASE, STAFFORDSHIRE
sj 9818.
880 ha
Grade 2
Most of the site is covered
by heather heathland, grading into
valley fen and bog, but the woods occupy a substantial part of the
area, particularly in the north. Four main woodland types can be
recognised:
1 Oak-birch woodland. Quercus
petraea and Betula verrucosa form a
closed canopy over much of Brocton Coppice, but large clearings
exist, and the margin of the wood grades into surrounding heathland.
The oaks are clearly much older than the birch, perhaps 150-200
years in most cases, with a few individuals of greater age.
2 Birch woodland. Betula
verrucosa woodland occurs in the vicinity
of Brocton Coppice and elsewhere in small clumps.
3 Alder coppice. The Sherbrook
valley has alder coppice along most
of its length.
4 Willow scrub. Contrasting
strongly with the Sherbrook valley, the
Oldacre valley has a discontinuous line of Salix cinerea in the
marsh of the valley bottom.
The open heath is invaded
by trees and shrubs and birch woodland is
the most widespread serai stage. Other species also occur, notably
sycamore in the Sycamore Hill area, Scots pine and beech in the
southern area, hawthorn in the vicinity of Brocton Field,
pedunculate oak particularly among the birch in the Oldacre valley
and gorse at various points on the heath.
Bracken is dominant over
some areas and apparently on the increase
in others. The heathland is a noted locality for hybrid Vaccinium
myrtillus and V. vitis-idaea (Vaccinium x intermedium). Empetrum
nigrum is also present.
There are several valley
bogs, reminiscent of those in the New
Forest. The best has a large expanse of Thelypteris palustris and
Equisetum sylvaticum, with a rich assemblage of bog plants including
Anagallis tenella, Carex pulicaris, C. dioica, C. hostiana, Drosera
rotundifolia, D. anglica, Eleocha-ris quinqueflora, Hydrocotyle
vulgaris, Orchis fuchsii, Par-nassia palustris, Pinguicula vulgaris,
Vaccinium oxycoccus and Valeriana dioica. Narthecium ossifragum
occurs in one of the valleys.
The insect fauna of the
whole area is extremely rich. Two of the
most notable Lepidoptera are Stilbia anomala and Enargia paleacea.
W.I23- HAMPS
AND MANIFOLD VALLEYS, STAFFORDSHIRE
SK 0955.
325 ha
Grade 2
The site follows the valley
of the River Manifold from Ecton
southwards towards Ham and incorporates part of the valley of the
River Hamps. The valleys contain woodland and scrub as well as
grassland. The woodlands are similar in many respects to the ash
woodlands of the Derbyshire Dales but exhibit some unusual features.
Thus old oak trees of Quercus robur and Q. petraea occur in several
places; and
holly is present, both as scrub and as a component of
established woodland. These features reflect some of the
characteristics of woodland under more oceanic conditions and
indicate a somewhat different climate on the extreme west of the
Peak District.
The woodlands of the Manifold
Valley show an extremely wide range of
variation in canopy structure and ground flora.
The grasslands included
within the site are on the whole damp and
well grazed. Agrostis spp. are generally dominant, but variations
occur according to slope and aspect. Potentilla tabernaemontani,
Carex pulicaris and Parnassia palustris are noteworthy amongst the
herbs.
Rare plant species present
include Polemonium caeruleum, Daphne
mezereum, Hordelymus europaeus, Festuca altissima, and Cardamine
impatiens. Daphne laureola, uncommon in the Peak District, is also
present.
The area is also of interest
for its karst topography. During
periods of dry weather the River Manifold disappears down a series
of swallets just below Wettonmill and the water resurges from
springs at Ham Hall about 11 km downstream. Thors Cave is an
impressive rock shelter perched on the side of the valley.
W.I24- BRAMPTON

Grade 2
Brampton Bryan Park lies
at the northern end of Renword-ine Hill on
steep east-, west- and north-facing slopes across a geological
transition between Old Red Sandstone and Silurian strata. The
woodland is ancient open oak parkland with sweet chestnut, beech,
ash and holly, with an area of wych elm woodland above a vestigial
dog's mercury field community. The ancient woodland is extremely
rich in epiphytic lichens.
The biological richness
of Brampton Bryan Park has been recognised
only recently. It is clearly very similar to Moccas Park and its
epiphyte flora is at least as rich but the invertebrate fauna has
not received a similar degree of study. (See Appendix.)

Grade 2
The ravine below Downton
Castle is wooded for a distance of over 2.4
km. The river has cut a deep gorge through Silurian rocks leaving
soils of an acid to weakly calcareous character. At higher levels
the woodland is mainly dominated by sessile oak, with a field layer
of Luzula sylvatica, but at lower levels a mixed deciduous woodland
occurs with ash and wych elm dominant. There is a wide range of age
classes, and one cliff has an old holly-ash-wych elm wood with a
vigorous colony of Festuca altissima. This is a sheltered site which
at lower levels is very rich in bryophytes, including Plagiopus
oederi, Pohlia cruda and many oceanic and submontane species. The
epiphytic lichen flora, though not inspected yet in detail, is
already known to be rich, with a fine colony of Lobaria pulmonaria,
Graphina anguina on holly and Peltigera horizontalis.
W.I26. BUSHY
HAZELS AND CWMMA MOORS, HEREFORDSHIRE

30 ha
Grade 2
This site lies c. 3 km
from the Radnor border on a level and damp
site, with loamy soils derived from Lower Old Red Sandstone rocks.
Ash is most abundant in the canopy though coppiced wych elm is often
co-dominant. Pedunculate oak and birch associate with them in
varying amounts though these are completely absent in some parts. A
stream divides off Bushy Hazels, a pure hazel coppice in the north-
eastern corner. The understorey and shrub layers are not well
developed throughout but the field layer is herb rich. Beneath the
hazel coppice are Deschampsia cespitosa and Endymion non-scriptus
with patches of Paris quadrifolia. In the ash-elm woodland, E. non-
scriptus, Anemone nemorosa, Mercurialis perennis and D. cespitosa
are predominant with Circaea lutetiana and Sanicula europaea. Wetter
patches contain Filipendula ulmaria, Chrysosplenium oppositifolium
and Carex pendula.
This site may be considered
alternative to Hill Hole Dingle, i.e. it
is an example of a mixed deciduous woodland on the Welsh borders. As
it has been heavily managed in the past, fewer native woody species
are present and the field layer is not as herb rich. The Dingle also
has more variety in its micro-habitats.
W.I27. LEIGHFIELD
FOREST, LEICESTERSHIRE
SK 7502. 170 ha
Grade 2
Leighfield Forest was recommended
for special status in Cmd 7122
(Ministry of Town and Country Planning, 1947) and relics of this
ancient woodland still remain. The site is composed of four woods
(Loddington Reddish, Tugby, Tilton and Skeffington woods) grouped in
the Eye Brook valley which runs through Jurassic ironstone and
clays. Deposits of boulder clays and gravels have resulted in rich
loamy and calcareous clay soils. The tree canopy is mainly standards
of oak plus wych elm, together with ash, often coppiced. The
understorey of hazel and field maple is often dense and there is a
mixed association of shrubs including dogwood, Midland hawthorn,
privet, sallow, elder and buckthorn.
Filipendula ulmaria and
Juncus spp. occur extensively in the rides
with Rubus fruticosus and Pteridium aquilinum locally abundant.
Beneath the coppice, Mercurialis perennis is dominant with clumps of
Deschampsia cespitosa and Dryopteris filix-mas. Myosotis sylvatica
is abundant and the presence of Vicia sylvatica, Campanula
trachelium and Dipsacus pilosus is of interest.
The more important Lepidoptera
of the Eye Brook valley include
Cymatophorina diluta, Nola confusalis, Ladoga Camilla, Nymphalis
polychloros, Quercusia quercus and Ochlodes venata which are rare or
not present elsewhere. The list of Coleoptera from these woods
includes a number of rare or localised species of which the
following are the most noteworthy: Platyrrhinus resinosus, Anthribus
fasciatus, Metoecusparadoxus, Lissodema quadripustulata, Hypophloeus
bicolor, Agapanthis villosoviridescens, Tetropium gabrieli, Pediacus
dermestoides and Nemosoma ekmgatum. The woods of this area are among
the most northerly known British localities for many species of
Coleoptera, including some of those listed above.
The earliest record of
these sites is 1235 and it is believed that
they have indeed been wooded since that time. The vegetation as a
whole is typical of that found on heavy boulder clay but this is
already represented in the grade I series by Monks Wood (W-42) and
Castor Hanglands (W-44), so Leighfield Forest is given grade 2
status.
W.I28. PIPEWELL

SP 8286.
80 ha
Grade 2
Monks Arbour and Pipewell
Woods lie on deep, calcareous clay soils
at the south-western extremity of Rockingham Forest and have a
coppice- with-standards structure. Pedunculate oak is the main
standard species, with ash, birch and a few planted beech. The
coppice layer is dominated by hazel, with ash, dogwood and field
maple locally abundant in Monks Arbour Wood. The field layer ranges
from Mercurialis perennis-Galeobdolon luteum on the drier soils, to
Filipendula ulmaria-Ranunculus repens in waterlogged patches, and
Pteridium aquilinum-Rubus fruticosus-Hokus lanatus on the more
acidic patches. The ground flora includes such local species as Iris
foetidissima and Campanula latifolia. At the southern end of
Pipewell Wood, English elm has invaded from the hedge to form a
nearly pure community.
This is one of the Ancient
Forest coppices. It is typical of such
woods and has the advantage that it is not damaged by ironstone
working or replanting with conifers, and indeed the coppicing
continues actively. Other woods in Rockingham Forest, however, were
once known to be richer faunally.
W.I29- WHITTLEWOOD
FOREST, NORTHAMPTONSHIRE
SP 7342. noha
Grade 2
Three relics of this ancient
woodland, in the south of the county,
still remain. They once formed a link in the chain of woodlands
which stretched across the clay belt from Oxfordshire to Huntingdon
and Peterborough. Lying on calcareous clays and boulder clays they
are typical examples of the woodlands on these soil types.
Buckingham Thick Copse is the largest area; it contains fairly
uniform oak-ash high forest. Understorey and shrub species are
confined to the rides and edges; these include field maple, dogwood,
Midland hawthorn and hazel. Sweet chestnut is also present. The
ground flora is dominated by Rubus fruticosus, Chamaenerion
angustifolium with Deschampsia cespitosa and Brachypodium
sylvaticum. Patches of Lusula multiflora and Carex pendula indicate
waterlogging. Say's and Smalladine Copses are similar but ash or
English elm outnumber the oak in parts. The shrub layer is better
developed here and is dominated by hazel. Cornus sanguined, Euonymus
euro-paeus and Viburnum opulus are common in the hedgerows.
Lichens that are absent
or rare elsewhere in the county are found
here; these include Lecanora confusa, Usnea certatina, Opegrapha
varia and Pertusaria lutescens.
East and West Ashall's
Copses consist of ash scrub and
mature ash woodland and
oak is only locally dominant. English elm
occurs on the edge and hazel, hawthorn, field maple and Midland
hawthorn are present in the understorey and shrub layers. The ground
flora here is dominated by bramble interspersed with areas of
Deschampsia cespitosa, Oxalis acetosella and Glechoma heeleracea.
Other plants include Sanicula europaea, Epipactis helleborine, E.
purpurata and Dactylorchis fuchsii.

FOREST, NOTTINGHAMSHIRE
SK 6368.
525 ha
Grade 2
The Birklands and, to a
lesser extent, the Bilhaugh are fine
remnants of Sherwood Forest.They lie on deep, freely drained acidic
soils developed from Bunter Sandstone. The woodlands are an actively
regenerating population of both oak species in more or less equal
numbers, with a wide size range from saplings to some of the largest
oaks in the country. Between these extremes are younger, but mature
generations of the oaks. Birch (mainly Betula pendula) is abundant,
forming groves between the oaks, but the canopy is still rather
open, enabling a dense bracken field layer to develop. The flora is
very poor, restricted to calcifuge species, and the epiphyte lichen
flora has been largely eliminated by pollution. The beetle fauna,
however, is very rich and contains some extremely rare species.
The oak population here
is exceptional but public pressure and
atmospheric pollution have damaged the area, hence it is accorded
grade 2 status.
Immediately to the north
lies Budby South Forest Heath (170 ha) on
soils derived from the Bunter Sandstone at an altitude of about 60
m. The heathland area is dry heath dominated by heather and
Deschampsia flexuosa. Much of it (c. 50%) is covered by scattered
birch or birch scrub. There is some gorse scrub but this habitat is
by no means abundant on the site. Bracken is only locally abundant.
The heath is at present
used as a military training area but there
is little apparent physical damage and the site has not been
extensively burnt in recent years. Its inclusion within the grade 2
site adds interest.
W.I3I. HABBERLEY VALLEY,
SHROPSHIRE

30 ha
Grade 2
This narrow, steep-sided
valley cuts through base-rich Ordovician
shales at its lower end and acidic pre-Cambrian conglomerates, which
give rise to two contrasting soil types, and strong associated
differences in the vegetation. The base-rich lower woodland is
dominated by wych elm, large-leaved lime, ash and yew with some
sessile oak: here the ground flora is a moderately rich assemblage
of mainly calcicolous species, with abundant Mercurialis perennis
and Polystichum setiferum, the rare Circaea intermedia and a range
of calcicole and calcifuge bryophytes. On the acidic rocks sessile
oak woodland grows over a ground flora of Vaccinium myrtillus,
Blechnum spicant and Leucobryum glaucum, with a number of Atlantic
bryophytes.
Several features have combined
to justify including this site. It
has good examples of two types of woodland whose distribution is
clearly determined by the nature of the under-and holly is present,
both as scrub and as a component of established woodland. These
features reflect some of the characteristics of woodland under more
oceanic conditions and indicate a somewhat different climate on the
extreme west of the Peak District.
The woodlands of the Manifold
Valley show an extremely wide range of
variation in canopy structure and ground flora.
The grasslands included
within the site are on the whole damp and
well grazed. Agrostis spp. are generally dominant, but variations
occur according to slope and aspect. Potentilla tabernaemontani,
Carex pulicaris and Parnassia palustris are noteworthy amongst the
herbs.
Rare plant species present
include Polemonium caeruleum, Daphne
mezereum, Hordelymus europaeus, Festuca altissima, and Cardamine
impatiens. Daphne laureola, uncommon in the Peak District, is also
present.
The area is also of interest
for its karst topography. During
periods of dry weather the River Manifold disappears down a series
of swallets just below Wettonmill and the water resurges from
springs at Ham Hall about 11 km downstream. Thors Cave is an
impressive rock shelter perched on the side of the valley.

very poor, restricted to calcifuge species, and the epiphyte lichen
flora has been largely eliminated by pollution. The beetle fauna,
however, is very rich and contains some extremely rare species.
The oak population here
is exceptional but public pressure and
atmospheric pollution have damaged the area, hence it is accorded
grade 2 status.
Immediately to the north
lies Budby South Forest Heath (170 ha) on
soils derived from the Bunter Sandstone at an altitude of about 60
m. The heathland area is dry heath dominated by heather and
Deschampsia flexuosa. Much of it (c. 50 %) is covered by scattered
birch or birch scrub. There is some gorse scrub but this habitat is
by no means abundant on the site. Bracken is only locally abundant.
The heath is at present
used as a military training area but there
is little apparent physical damage and the site has not been
extensively burnt in recent years. Its inclusion within the grade 2
site adds interest.
W.I3I. HABBERLEY VALLEY,
SHROPSHIRE
sj 4104.
30 ha
Grade 2
This narrow, steep-sided
valley cuts through base-rich Ordovician
shales at its lower end and acidic pre-Cambrian conglomerates, which
give rise to two contrasting soil types, and strong associated
differences in the vegetation. The base-rich lower woodland is
dominated by wych elm, large-leaved lime, ash and yew with some
sessile oak: here the ground flora is a moderately rich assemblage
of mainly calcicolous species, with abundant Mercurialis perennis
and Polystichum setiferum, the rare Circaea intermedia and a range
of calcicole and calcifuge bryophytes. On the acidic rocks sessile
oak woodland grows over a ground flora of Vaccinium myrtillus,
Blechnum spicant and Leucobryum glaucum, with a number of Atlantic
bryophytes.
Several features have combined
to justify including this site. It
has good examples of two types of woodland whose distribution is
clearly determined by the nature of the under-lying rocks. It is one
of the few sites where the native large-leaved lime occurs, and here
it is locally dominant, with many fine specimens. Furthermore, the
woodland is part of a complex of habitats which taken together
include a rich variety of plant species.
W.I32. CHADDESLEY-RANDAN
WOODS, WORCESTERSHIRE
so 9273.
170 ha
Grade 2
These woods lie on Keuper
Marl from which a poorly drained, rather
acidic, loamy clay soil develops, but the higher ground is capped by
glacial drift of a sandy and gravelly character on which freely or
excessively drained, light, strongly acidic soils have formed. The
woodland is almost entirely dominated by mature oak high forest in
which both native species are represented. There is a tendency for
most oaks on the light soil to be Quercus petraea and most on heavy
soils to be Q. robur, but this is not a particularly close
relationship and mixed populations are widespread. A coppice and
shrub layer is present throughout, although it is thin on the most
acid soils, and consists of a mixture of species, including hazel,
ash, alder and birch. A considerable number of native tree and shrub
species are present in small numbers. Along the deeply incised
stream lines, influenced by calcareous water, a rich alderwood has
developed.
A number of local plant
species are present, including Epipactis
purpurata and Carex strigosa, but no nationally rare species are
recorded. The fauna includes the rare terrestrial caddis fly
Enoicyla pusilla.
The scientific interest
is not confined to the woodland for a number
of small herb-rich meadows and green lanes occur within the woods.
One in particular, in the centre of Chaddesley Woods, occupies a
receiving site on heavy clay, and has developed as a meadow/marsh in
which Serratula tinctoria, Silaum silaus and various Dactylorchis
spp. are present.
Chaddesley-Randan Woods
are undoubtedly the most important to nature
conservation of the group of woods which were formerly within
Feckenham Forest. The others, centred on the parish of Himbledon,
are much more uniform where they survive as native woodland. The
richest woods in this group have recently been clear-felled, but it
is doubtful whether even they were richer than Chaddesley-Randan
Woods.
These woods have been included
in the Review primarily as an
extensive and rich example of the oak woodlands in the West
Midlands, and are more closely related to the Wealden oak woodlands
than the coppice-with-standards woods typical of much of the
Midlands. In so far as they possess significant stands of sessile
oak woodland on acidic, freely drained sandy soils, in association
with pedunculate oak-wood in an apparently natural distribution,
Chaddesley-Randan Woods are similar to Wyre Forest (W.i2i).

SP 9229. 230
ha
Grade 2
King's Wood, together with
Baker's Wood, is the largest area of
woodland in Bedfordshire. It lies on boulder clay passing to Lower
Greensand. The sandy soils are covered by birch woodland with some
sessile oak and Scots pine over bracken and in open areas heather.
The clays on the other hand have pedunculate oak-ash woodlands in
which hornbeam is co-dominant over large areas, and some stands of
small-leaved lime. Here the ground flora is predominantly of Primula
vulgaris, Euphorbia amygdaloides, Mercurialis perennis, Galeobdolon
luteum and Lonicera peridymenum. The woods have a number of rare and
local plant species, including Convallaria majalts, Osmunda regalis,
Luzula sylvatica and Vicia sylvatica.
Although the site has been
partly damaged by development and
replanted with conifers, it remains a rich and diverse wood, and the
damage is not irreversible. Its flora and fauna are relatively well
known, and include national and regional rarities in the fungi and
Hemiptera.

W.23- WINDSOR FOREST,
BERKSHIRE
su 9373.
710 ha
Grade i
An area of 3150 ha of Windsor
Forest is managed commercially by the
Crown Estate. Of this, approximately 1200 ha consists mainly of oak
woodland or mixed woodland in which the oak complement will be
progressively enhanced by thinning. At High Standing Hill 18 ha of
unmanaged woodland contain oak and overmature beech in the best
surviving piece of the original Forest. This extends farther west on
either side of a stream valley where remnants of old beech-oak
woodland predominate with an epiphytic lichen flora of 58 species,
including some old-forest relics. The ancient oaks of The Parks have
a number of other lichen species. Although the ground flora tends to
be poor on the Bagshot Sands such areas have proved outstanding for
oak regeneration.
Windsor Forest probably
ranks second only to the New Forest with
regard to the richness of its insect fauna. It is particularly noted
for many rare beetles associated with the old oaks and Donisthorpe
(1939) published an impressive list. With more recent additions the
total number of Coleoptera recorded from the forest must number
close on 2000
species. Some very rare beetles are known in this
country only from the Windsor and Sherwood Forests. With the
destruction of most of the latter, species such as Teredus
cylindricus and Cryptocephalus querceti may only be able to survive
in Windsor. Although individual entomologists would probably
nominate particular areas as outstanding from their particular
specialist point of view, it is the size of the Forest as a whole,
forming a nucleus within a much larger area of well-wooded
countryside, that is of paramount importance. The maintenance of the
high entomological importance of this area depends on sufficient oak
and beech trees being allowed to become overmature, die, and rot in
situ, as is the present management practice.

W.22. BRADENHAM
WOODS, BUCKINGHAMSHIRE
SU8397. 180 ha Grade
i The Bradenham Woods are examples of plateau
and dip slope Chiltern woodlands, comprised of the three almost
contiguous Naphill, Bradenham and Park Woods. As a group they are
believed to be the best example of this type in the Chilterns.
Naphill Common is an oak
(Quercus robur and Q. petraea)-beech
woodland with some birch. Holly and cherry also reach the canopy
though they are more frequently present in the understorey with
elder, willow, whitebeam, rowan and yew. Bramble with wood sorrel,
bracken and honeysuckle are abundant in the field layer and heather,
unusual in this area, is present in the rides. Apparently in the
18905 parts of this wood were open, with gorse and juniper 4.5-6 m
high.
Bradenham Wood is a well-grown
dip slope beechwood north of Naphill
Common with occasional sycamore, pedunculate oak and whitebeam. Both
beech and oak are regenerating. One area has been clear-felled
(1969) and young beech has been planted at 120 cm intervals. The
ground flora is predominantly bramble-wood sorrel though much of the
ground is litter covered. Many other calcifuge species are common,
including heather, foxglove and Potentilla erecta. A dew pond at the
summit and Sarsen pits add to the variety of habitat.
Park Wood lies north of
Bradenham and is separated from it by an RAF
housing estate. A small area of scrub grassland, managed by the
Berkshire, Buckinghamshire and Oxfordshire Naturalists' Trust, is at
the north-west corner. The beech woodland is richer in shrub and
herbaceous species than Bradenham and regeneration of both beech and
pedunculate oak is taking place. Other canopy species present are
sycamore, ash and yew, The trees, at 160 years, are some of the
oldest in the Chilterns. Shrub species include field maple,
clematis, hazel, holly, privet, gean, willow, wayfaring tree and
guelder rose. The field layer consists mainly of Galeobdolon luteum-
Geranium robertianum-Rubus fruti-cosusMercurialis perennis-Sanicula
europaea with sheets of ivy in places.

This woodland occupies
a low plateau intersected by shallow valleys,
on coarse gravelly sands derived from Reading Beds and areas of
superimposed plateau gravel. Structurally the woods are very diverse
with ancient pollards, closed stands of younger but mature woodland,
old coppice and scrub by open grassland. Beech is the most abundant
species, with pedunculate oak, birch and holly also locally
abundant. The field layer is sparse, with mainly calcifuge species
such as Deschampsia flexuosa, Luzula pilosa, bracken and in open
areas heather and other heathland species. Although it is so close
to London, it retains a moderately rich epiphytic lichen flora,
including Graphis elegans and Thelotrema lepadinum. The rare moss
Zygodon forsteri is also recorded. This wood has similarities to the
New Forest, but differs structurally and is inferior in extent,
diversity and floristics and so is not an alternative site.

Although it is clearly a separate site, it could be considered with
Bradenham Woods: taken together these include most of the range of

W-57- HARDWICK
WOOD, CAMBRIDGESHIRE
TL 3557.
16 ha
Grade 2
This is an example of woodland
on Chalky Boulder Clay, in which the
ancient core is oak-ash woodland with a coppice layer of hazel, in
which oak is much more abundant than ash. Surrounding this ancient
core is secondary woodland arising at various dates from the
sixteenth century to about 1930, which includes a variety of types
with wych elm, ash and birch locally dominant. The ground flora
includes abundant oxlip and, on the wood margin, Melampyrum
cristatum and Lathyrus sylvestris. The bryophytes include the rare
Ptilidium pulcherrimum.
In a general sense, this
site is an alternative to Hayley Wood, but
it has its own features of scientific importance. Its management
history is exceptionally diverse and well documented: similar
secondary woodland series occur in other woods selected, but these
are comparatively recent(e.g. Hintlesham Woods, Suffolk). Unlike
other Cambridgeshire woods it has apparently never had a significant
tall coppice component of ash and field maple. There is a classic
primrose-oxlip hybrid situation, which can be related to the
development of the wood.

W-4O. HAYLEY
WOOD, CAMBRIDGESHIRE
TL 2953.
50 ha
Grade i
Hayley Wood stands on the
Chalky Boulder Clay plateau on soil which
is heavy and waterlogged or flooded for much of the year.
Structurally it is coppice-with-standards, with both large coppice
of field maple and ash and small coppice of hazel and hawthorn below
a thin canopy of pedunculate oak standards. Small areas have been
invaded by Ulmus carpinifolia over the last 200 years. The ground
vegetation forms concentric zones from the wet middle and north,
dominated by oxlip and Filipendula ulmaria, to the drier eastern,
southern and western fringes dominated by dog's mercury. The
intermediate zones have the richest plant communities, with tracts
of bluebell and Galeobdolon luteum. The coppice plots in the wetter
area have luxuriant vegetation resembling fen communities, with
Cirsium palustre, Ranunculus flammula and Galium palustre. A number
of rare and local species occur, including Melam-pyrum cristatum,
Serratula tinctoria, Sedum telephium, Ophioglossum vulgatum and
Centaurium pulchellum. About 250 species of vascular plant have been
recorded, including 29 native tree and shrub species.
Hayley is one of the largest
of the boulder clay woods. It has
perhaps the largest single population of oxlip, and this in a site
lacking primrose. It has a rich bryophyte flora for eastern England,
notable for the inclusion of Nowellia curvifolia. It is almost
wholly an ancient wood, with a recorded history of over 700 years,
embodying the typical features of other ancient coppice woods in the
vicinity. Furthermore, it has been used for research and teaching
for many years. It is one of a number of boulder clay coppice woods
selected, which cover a range of soil types from very light (Swanton
Novers Woods), light (Hintlesham Woods) to heavy (Hayley Wood) and
transitional to fen carr (Fel-shamhall and Monks Park Woods, where
there is a range of conditions, including light soils).

W-56. OVERHALL
GROVE, CAMBRIDGESHIRE
TL 3363.
20 ha
Grade 2
This site lies on moderately
steep slopes. The soil throughout is
heavy clay, with calcareous boulder clay at high levels and neutral
or mildly acidic Kimmeridge Clay at low levels. Ulmus carpinifolia
is dominant throughout with some pedunculate oak, ash, field maple
and elder. It is probable that the wood originally had a fairly
conventional coppice-with-standards structure, with oak and elm over
ash and maple, but in recent centuries the elm has spread
vigorously. Some massive elm and oak standards remain, however, and
in its present state Overhall Grove approximates to high forest
closer than most woods in the east Midlands and western East Anglia.
The ground flora includes a vast population of oxlip and some other
woodland species, but is mostly dominated by Urtica dioica, Glechoma
hederacea, Galium aparine and Heracleum sphondylium.
Other areas of small-leaved
elm woodland are known in the area. This
one is selected partly because of its structural maturity and oxlip
population, but it also has a number of peculiar features. Within it
is an extensive field monument (the Hall of the name) and associated
earthworks which, with other information, indicates that the wood is
ancient, secondary woodland, with no primary woodland nucleus. Its
importance is increased by the selection of Hayley Wood (mainly
primary with a small, recent, secondary area) and Hardwick Wood
(primary and a succession of secondary, adjacent stands) on similar
soils and in the same area, for Overhall is a particularly fine
demonstration of the long-lasting effects of discontinuity of
woodland cover on the woodland flora.

W.62. DIZZARD-MILLOOK
CLIFFS, CORNWALL
sw 1799.
60 ha
Grade I
The cliff woodlands on
this site have a north to northeasterly
aspect and an altitude range from sea-level to approximately 150 m
at the highest point. The area of cliff over which the woodland has
developed is subject to landslips. This, combined with a friable
rock type, has given the steeply sloping cliffs a varied topography.
The tree layer is exposed to strong winds from the sea and this has
resulted in a tight wind-pruned canopy. As a direct consequence of
the varied topography and wind-pruning the canopy height varies
between i and 8 m, and is composed mainly of sessile oak together
with some birch and rowan. Of interest is the occurrence in the
canopy of wild service, a species rare in the south-west. The shrub
layer is represented by hazel, hawthorn, holly, privet, gorse and
spindle. The edges of the woodland both on the seaward side and near
the cliff top have a scrub margin in which blackthorn is well
represented. Scrubby patches are also found where recent land-slips
have caused disturbance. The ground flora of the area is extremely
varied for this part of the country and includes both basiphilous
and acidophilous areas of vegetation. Areas on the base-rich soils
support Allium ursinum, Arum maculatum, Filipendula ulmaria,
Fragaria vesca, Sanicula europaea, Primula vulgaris and
Mercurialisperennis, whilst in contrast to these may be found a
ground flora dominated by Vaccinium myrtillus, Calluna vulgaris,
Deschampsia cespitosa and Melampyrum pratense. Dryopteris aemula is
also present within the woodland. This contrast of vegetation types
is also reflected in the shrub layer. The epiphyte flora is well
developed: Lobaria pulmonaria is to be seen throughout the wood and
Sticta limbata has also been found.

generally acidophilous with much Luzula sylvatica, Vaccinium
myrtillus and Blechnum spicant but on the better soils bracken and
bramble occur with species such as Sanicula europaea on the best

This woodland is notable
mainly for its bryophyte communities and
there are some rare species. The filmy fern Hymenophyllum

60 ha
Grade i
This site is a complex
of saltings, salt marshes, carr and woodland
situated in the valleys and around the confluence of the rivers Fal
and Ruan. Its particular interest lies in the transition from salt
marsh through an invasive stage to tidal woodland which is rare in
Britain. The history of the site is known and studies on the
stratigraphy and the plant and animal communities in relation to
tidal submergence have been carried out. The tidal area of woodland
is dominated by Alnus glutinosa together with Salix cinereavar
atrocinerea, the willow in places forming a scrubby boundary to the
more mature woodland and extending out into the surrounding
marsh. Passing up the river
valley the tidal woodland grades into a
birch-oak wood. On the sides of the valley and, in many places
sharply defined from the marsh by a boundary ditch or bank, is a
drier acidophilous oakwood. Here sessile oak has been coppiced and
some hazel, hawthorn, rowan, willow and gorse are present. The
ground flora includes species such as Calluna vulgaris, Vaccinium
myrtillus, Blechnum spicant, Rubus sp., Lonicera periclymenum and
Holcus mollis together with bryophytes including Thuidium
tamariscinum, Dicranum majus and Hypnum cupressiforme.
In contrast to this the
alder tidal area contains Angelica
sylvestris, Oenanthe crocata, Galium palustre, Juncus sp., Caltha
palustris and Carex spp. as well as occasional occurrences of salt
marsh species.

found. Beech and holly are present in the canopy. In the lower parts
of the wood the trees overhang a bank and then estuarine mud in
which are patches of Spartina marsh. In the lower parts of the wood,
rowan, alder buckthorn and gorse are to be found.
The ground flora in the
upper parts and hazel coppice region is
dominated by bluebell together with wood anemone, bramble, Blechnum
spicant and Lonicera peri-clymenum. Near the river, bracken is
frequent as are bilberry, Luzula pilosa, heather and Teucrium
scorodonia illustrating a more acidophilous facies. A large active
badger sett is present within this area of woodland.

Borrowdale probably contains
a greater extent of native woodland
than any other of the Lakeland valleys, and from the road it can
appear that almost the whole dale is forest clad on its lower slopes
- an impressive effect. Most of the woods are of the hanging type,
on steep slopes ranging from c. 75 to 370 m, and covering all
aspects, but The Ings and Castle Head Wood lie on the floor of the
valley: the latter on a small hill. The parent rock is almost
entirely the Borrowdale Volcanic Series, which generally gives
acidic soils, but contains calcite bearing beds (and fault shatter
belts) in many places, as at Lodore and in Seatoller Wood. The
slopes within most woods are variably covered with block scree.
These are composed of rocks of all sizes. Many woods have outcrops
which vary in size from small faces to high cliffs around Lodore.
These woods lie within a very sharp rainfall gradient ranging from
about 178 cm annually at Castle Head Wood to about 318 cm at
Seathwaite.
There are fine stands of
high forest sessile oakwood in Great Wood,
Johnny's Wood and Seatoller Wood, and smaller coppice in Troutdale.
A shrub layer is generally absent and there are merely scattered
individuals of birch, holly and rowan. Ash-hazel wood occurs in all
sites except The Ings, but forms a large part of Seatoller Wood and
its juxtaposition here with sessile oakwood illustrates the same
kind of edaphic separation of woodland types as that found in the
lowland situation with slate and limestone in Roudsea Wood. The
ashwood contains a good deal of wych elm, and there is usually an
understorey of hazel, plus a greater variety of shrubs such as
Primus padus, P. spinosa, Crataegus monogyna and Rubus fruticosus.
The respective field communities are of Deschampsia flexuosa-
Anthoxanthum odora-tum, with sparse bilberry and much bracken on
leached brown earths under oak, and Brachypodium syhaticum-Geranium
robertianum with numerous other basiphilous herbs on base-rich loams
under ash-hazel. Rare herbs include Festuca altissima at Lodore and
Great Wood, Impatiens noli-tangere in Great Wood and Circaea alpina
in several localities; the last two species have their British
headquarters in Lakeland.
Castle Head Wood differs
from the others in a number of respects. It
is well-developed sessile oak over hazel woodland surrounded by
farmland and not open to the upland fell. This has reduced grazing
pressure, which in turn has enabled some natural regeneration to
take place and accounts for the relatively strong development of
field and shrub layers.
By the shore of Derwentwater
near Lodore, a fringe of alder, willow,
reed and sedge completes the ecological zona-tion of the catena from
the top of the hanging oakwoods to the lake shore. Alder woodland
near the lake is an important feature of Great Wood and is
exceptionally well-developed in The Ings. This site, although small,
is ungrazed, and the good field layer varies according to the
mineral/humus component of the substratum which may depend on
variations in silting from the inflowing stream.
Fern communities are well
developed, especially on block scree and
include Dryopteris filix-mas, D. dilatata, Athyrium filix-femina,
Thelypteris oreopteris, T. phegopteris, T. dryopteris and Blechnum
spicant. The rare Asplenium septentrionale grows on rocks in one
place. There is a general carpet of bryophytes composed of the
common species appropriate to oak and ash-hazel woods, but the most
important feature is the strong representation of the Atlantic
element. These woods, including the famous cascade ravine of Lodore
Falls, together constitute the most important locality in England
for Atlantic bryophytes and in richness they rival those of north
Wales and the western Highlands. The Hymenophyllum wilsonii-Scapania
gracilis-Plagiochila spinulosa community on blocks is well
developed, and there is local abundance of mosses such as Hylocomium
umbratum, Hypnum callichroum, Bartramia halleriana and the northern
Ptilium crista-castrensis, and Sematophyllum novae-caesareae. The
notable hepatics include Radula valuta, R. aquilegia, Jubula
hutchinsiae, Colura calyptrifolia, Plagiochila tridenticulata,
Frullania germana, F. microphylla, Marchesinia mackaii, Adelanthus
decipiens, Sphenolobus helleranus and Jamesoniella autumnalis.
Borrowdale appears to be especially rich in moisture-loving species
not only because of its western position and heavy rainfall, but
also because of the apparent historical continuity of woodland cover
in places. Seatoller Wood faces south-east and it is difficult to
account for the abundance of moisture-loving bryophytes, including
several species with very limited powers of spread, except in terms
of continuous Post-glacial woody cover.
The Borrowdale Woods are
equally important for oceanic lichens; the
main interest lies in the presence of a corticolous association,
characterised by the co-dominant Parmelia laevigata and P.
taylorensis. A total of 111 species have been recorded from
Seatoller Wood, which include species such as Bacidia affinis, B.
isidiacea, Lecides berengeriana, Lopadium pezizoideum, Micarea
violacea and P. plumbea which are all very rare in Britain.
Great Wood is one of the
best localities in England for arboreal
lichens, including large foliose species such as Lobaria pulmonaria,
L. laete-virens, Sticta sylvatica and S. limbata.
The woods nearer the dale
head were once, and perhaps still are, the
haunt of the pine marten, and they have the red squirrel, now
reduced and local. The more notable breeding birds include common
buzzard, pied flycatcher, wood warbler and grey wagtail.
These Borrowdale Woods
are a key station in the internationally
important series of western hill woodlands with rich Atlantic
floras, and as a group they are clearly in the first echelon of
grade i sites.

W.I48. GOWBARROW
PARK, CUMBERLAND
NY 4120.
85 ha
Grade 2
The southern edge of Gowbarrow
Park around Yew Crag consists of a
mixture of woodland, grassland and heath on steep slopes and bottom
lands overlooking the northern shore of Ullswater, at 150-275 m. Two
distinct kinds of woodland occur. On the low-lying ground at the
foot of the slopes the woodland is dominated by alder with a few
ash. In Dobbins Wood and higher up the valley of the Collierhag
Beck, much of the alder is open - in Dobbins Wood it was coppiced
within the last decade and has been kept open by grazing - but in
the area south and west of Yew Crag it mostly forms a closed canopy.
The soil here is a flushed silty material with boulders at the base
of the slopes, mildly acid or neutral in reaction and slightly
gleyed. The ground flora is extremely rich with numerous marshland
species especially in the open alder areas.
On the steep south- and
east-facing slopes most watercourses and
rocky bluffs are occupied by open irregular woodland in which wych
elm, ash and hazel are abundant. Many other species occur there
including bird cherry, yew and sessile oak. This kind of woodland is
best developed on Yew Crag, whence it grades westwards into a
distinct variant, resembling in some respects the woodland of
calcareous soils south of the Lake District. This lies on the steep
south-facing slopes immediately above the oak, and is characterised
by the presence of pedunculate oak, small-leaved lime and spindle
and the absence of sessile oak in the mixture which includes wych
elm, ash and hazel. The soil on the craggy slope varies considerably
in depth, stability,
base-status and wetness,
but seems mostly to be mildly acid or
neutral. The rock outcrops belong to the Borrowdale Volcanic Series
and vary from strongly acidic to markedly calcareous.
The alder woods thin out
below Collier Hagg to open, acidic, flushed
grassland and bracken on drier areas. Between the patches of crag
woodland and on the hillside above are heathland communities ranging
from bracken to a mixture of Vaccinium myrtillus, Calluna vulgaris,
Erica cinerea and Nardus stricta.
The lichen flora is rich,
both in the lower alderwoods and on the
steeper wooded slopes and cliff's. Gowbarrow supports a fine
assemblage of relic forest lichen species within which Lobaria spp.
are particularly well developed.

W.I34. KESKADALE
AND BIRKRIGG OAKS, CUMBERLAND
NY 208195, NY 215205 and
NY 220205. 9 ha
Grade i
These two small areas of
woodland are situated on the southern
slopes of two adjacent mountain ridges. The Birkrigg area extends
from 350 to 430 m and the Keskadale Oaks from 300 to 460 m. A
shallow acidic soil is formed by the weathering of the shaly rock of
the Skiddaw Slate Group.
These woods are almost
completely of sessile oak with a few
scattered rowans. The oak in both areas is low and springs from
multiple stems and at least in the Keskadale Wood coppicing has
probably taken place. However, coppicing is not the sole reason for
the growth form, as factors such as fire, grazing, disease and
bruising of the tree base all contribute. The woods apparently
differ in that there is much more active scree in and near the
Birkrigg Oaks whilst the Keskadale Oaks have a more stable as well
as more grazed appearance. Both woodlands are wind-pruned, with
stature of the trees decreasing to that of scrub at the upper edges,
especially in the Keskadale wood.
The field layers in both
woods are similar and open as the thin fine
soil layer tends to get broken and eroded. Bilberry is dominant
together with bracken and heather, the heather becoming dominant
where the canopy is open. Other species common in the field layer
include Blechnum spicant, Des-champsia flexuosa, Potentilla erecta,
Agrostis canina, Galium saxatile, and Oxalis acetosella. Bryophytes
are abundant and Dicranum scoparium, Hypnum cupressiforme and
Pleurozium schreberi occur frequently. Epiphytic bryophytes and
lichens clothe most of the trunks, with Ulota sp. common on the
upper twigs.
These woodlands represent
relict fragments of high-level sessile
oakwood and may be near the altitudinal limit for oak woodland in
western Britain.

W.I47- LYNE WOODS,
CUMBERLAND
NY 4569.
115 ha
Grade 2
These consist of a series
of ungrazed lowland gorge woodlands along
the course of the River Lyne. The lowest section, near Kirklinton,
has only thin fringes of ash-oak-wych elm-hazel wood, and is
interesting mainly for its crags of New Red Sandstone, which is here
moderately calcareous in places and supports species such as
Myosotis sylvatica, Carex pendula, Phyllitis scolopendrium,
Polystichum lobatum and Equisetum hyemale. There is a rich bryophyte
flora. The section above Waingatehead is cut mainly through acidic
beds of Carboniferous sandstone; it has more oakwood and is notable
for the abundance of Atlantic bryophytes. There is an isolated small
colony of Hymenophyllum tunbrigense. The basic soils have a field
layer with Mercurialis perennis, Primula vulgaris, Sanicula
europaea, Stellaria nemorum and Carex sylvatica on drier ground, and
Ranunculus repens, Chrysosplenium oppositifolium, Filipendula
ulmaria and Carex remota where it is wet. The acidic brown earths
have an abundance of Luzula sylvatica, Vaccinium myrtillus, Oxalis
acetosella, Dryopteris austriaca and D. filix-mas.
The upper section, below
Kinkry Hill, is cut through Carboniferous
sandstones and shales, and has a mixture of the acidic and basic
woodland types described above. Another distinctive type on a wet
river terrace here is an ungrazed alderwood, with wet mull soils
carrying Carex acutiformis, C. paniculata, Equisetum telmateia,
Paris quadrifolia and Phalaris arundinacea. Through all sections,
the high flood level of the river produces a zone of enrichment
which supports numerous basiphilous vascular plants and bryophytes,
and these include Trollius europaeus and Geranium sylvaticum in the
upper section, which is closer to the source of the river on the
Bewcastle Fells of north Cumberland.

W.I35- ORTON
MOSS, CUMBERLAND
NY 3454.
50 ha
Grade i
These very mixed woods
are developed partly on a former peat moss,
possibly of the raised mire type but probably grading into valley
mire. Areas of Scots pine are periodically cut and replanted, but
this tree regenerates very freely naturally. Pinewood has a typical
bilberry-moss community, but Dryopteris dilatata is locally
abundant. The pine stand felled around 1958 had a good colony of
Goody era repens, but this has not been found in other areas of
pine. A good deal of sessile oak is scattered through the woods,
usually mixed with Scots pine and birch, and birch also forms pure
stands of different ages with some trees reaching a large size.
There is also much rowan, hazel and holly, and more locally, alder
buckthorn. In one place, old peat diggings in the original
ombrotrophic peat carry an acidophilous mire vegetation with a
Sphagnum carpet and Myrica gale, Andromeda polifolia, Oxycoccus
palustris, Carex curta and Osmunda regalis.
Heathery clearings on dried
out peat have gradually developed a
subspontaneous growth of Scots pine and birch during recent years.
The former valley mire which floods during winter has a poor-fen
with a great deal of Carex rostrata, Calamagrostis epigejos and
Dryopteris spinulosa. In this part of the woods there is a much
mixed willow (mainly Salix «'»eraz)-alder-birch swamp woodland with
a Sphagnum recurvum-S. auriculatum floor. Pyrola minor is frequent
in these damper areas. While the soils are mostly acidic, a few
areas of more basic loam occur on which grow herbs such as Geum
rivale, Circaea lutetiana, and Sanicula europaea. Ivy and polypody
commonly occur as members of the field community on dry acidic soils.
Orton Moss is especially
interesting for the old hay meadows which
occur around the edges, especially on the south and west sides.
These unploughed and herb-rich meadows grade into the woodland, and,
because of the abundance of Succisa pratensis, the larval food
plant, are celebrated as the haunt of the marsh fritillary
Euphydryas aurinia. The whole area is extremely rich entomologically
and rates highly on this account. Ornithologically, it is important
as the breeding haunt of at least three pairs of sparrowhawks, and
it also contains a good range of other woodland bird species.

W.I46. SCALES
WOOD, CUMBERLAND
NY 1616.
30 ha
Grade 2
Scales Wood lies between
100 m and 250 m on a fairly steep slope of
Ennerdale Granophyre facing north-east. From its position on the
lower slopes of the High Stile range in the high fells of western
Lakeland, the wood receives a heavy rainfall of about 203 cm
annually, and the shaded aspect enhances atmospheric humidity. The
parent rock gives mainly acidic soils and the lower part of the wood
is a well-grown stand of high forest sessile oak with few
undershrubs since there is sheep-grazing throughout, though
scattered birches fulfil this role in places. The upper part of the
wood consists of fairly pure birchwood, though this is probably
serai as it lies well within the altitudinal range of oak. The
ground is generally block littered and there is a luxuriant fern and
bryophyte flora, with abundance of Atlantic species such as
Hymenophyllum wilsonii, Plagiochila spinulosa, Scapania gracilis,
Hylocomium um-bratum and the rare moss Sematophyllum novae-
caesareae, unknown elsewhere in England outside Borrowdale. At the
upper edge of the wood the grassy field layer grades into bilberry
heath with a high cover of Sphagnum capillaceum and S.
quinquefarium. There is an old record of Festuca altissima, probably
referring to the ravine of Far Ruddy Beck, where calcareous rocks
bear a more varied flora.
This site could be regarded
as an alternative to Johnny's Wood
(W.i33(e)), but is too small and limited in range of habitat,
vegetation and flora to take the place of the Borrowdale Woods as a
whole.

W.II5- DERBYSHIRE
DALES WOODLANDS,
DERBYSHIRE/STAFFORDSHIRE Grade
I*
The Low Peak of Derbyshire
contains one of the most important masses
of Carboniferous Limestone in Britain. In the river valleys or Dales
coming from this area are a series of ashwoods occurring on steep
hillsides over a thin rendzina soil or on scree. These woodlands
together with those of the Mendip Hills exhibit the best-known
development of ashwood. The areas are for the most part ungrazed and
have a rich shrub and field layer. A series of woodlands is listed
in order to cover the range of variation; these areas are also
associated with key grassland sites. Historical documentation
indicates that the bulk of the woodland in the Dales area has
originated since the middle of the seventeenth century.
(a) Lathkill Dale SK 1865.
70 ha
Lathkill Dale is orientated
east-west and lies just south of
Bakewell. Some woodland on the north and east end has been modified
by planting but the remainder of the area contains some fine
ashwood. Species found with the ash include wych elm, hazel, privet,
guelder rose, field maple, elder, hawthorn, dog rose, gooseberry and
rowan. The field layer is locally dominated by Mercurialis perennis
or Deschampsia cespitosa together with ferns but there is a wide
variety of forbs present including much Geum rivale, Galeobdolon
luteum, Campanula trachelium, Poa nemoralis, P. trivialis,
Brachypodium sylvaticum and Melica uniflora. A long list of
characteristic but less common species is to be found including
dogwood, Daphne mezereum, Convallaria majalis, Neottia nidus-avis,
Helleborus viridis, Gagea lutea, Litho-spermum officinale, Mycelis
muralis, Asperula odorata, Cirsium heterophyllum,Hypericumhirsutum,
Tamus communis, Euonymus europaeus, Milium effusum, Zerna ramosa and
Festuca gigantea. Occasional old lead workings add interest as the
spoil heaps support a rich flora with species such as Helianihemum
chamaecistus, Campanula glomerata, Orchis fuchsii, Minuartia verna
and Briza media. See also L. 124(1) and OW.44-
(b) Cressbrook Dale
SK 1773.
25 ha
The Dale runs in a north-south
direction, is steep sided and
contains some good limestone crags. The tree canopy is of ash with a
little wych elm and a dense shrub layer of bird-cherry, field maple,
buckthorn, guelder rose and hazel. There are patches of aspen-
dominated scrub. The lower part of the Dale appears to have been
disturbed to some extent and here sycamore is more abundant. There
is some good cliff scrub with rowan, rock whitebeam, yew, small-
leaved lime and wych elm. The field layer is dominated by
Mercurialis perennis with patches of Allium ursinum and Convallaria
majalis. Melica nutans and Campanula latifolia are frequent. There
is an interesting juxtaposition of grassland and woodland in the
Dale as well as species-rich mine spoil heaps where Minuartia verna
is common. The Dale also contains the only known English locality
for the rare moss Thamnium angustifolium. It has been suggested that
the presence of small-leaved lime together with Convallaria majalis,
bird- cherry and dogwood indicates that at least a part of the
area may be primary woodland. See also L. 124(1).
(c) Dove Dale Ashwood SK
1453. 20 ha
The craggy valley of the
Dove runs north-south and has good woods on
both east and west aspects. Dovedale Wood itself is dominated by ash
with beech, holly (very local), field maple, sycamore and
pedunculate oak. It has been suggested that the wood can be regarded
as intermediate between pure ashwood and the oakwoods of western
Britain. There are areas of fine cliff woodland dominated by yew
together with Sorbus aucuparia, S. aria, S. rupicola, Prunus
spinosa, Ribes alpinum, Rosa pimpinellifolia and Crataegus monogyna.
The herbaceous flora is varied; areas near the river are dominated
by Filipendula ulmaria, Phalaris arundinacea, Veronica beccabunga
and Petasites hybridus whilst on many of the slopes Mercurialis
perennis, Geum urbanum, Brachypodium sylvaticum, Fragaria vesca and
Deschampsia cespitosa are dominant. Where the ground is broken by
outcrops and the canopy is more open a rich assemblage of forbs is
present, at times approaching a limestone grassland sward in
composition. See also L. 124(1).

W.&7. AXMOUTH-LYME
REGIS UNDERCLIFFS, DEVON
SY 255898-333914. 320 ha
Grade i
This site, on the south
Devon coast on Lyme Bay, extends from west
of Lyme Regis to the mouth of the River Axe.
The area is of stratigraphic
importance and includes outcrops of
Triassic, Rhaetic and basal Lower Lias exposures of the sub-
Cretaceous unconformity, the most westerly exposure of the Gault
Clay as a distinct lithology, examples of penecontemporaneous
erosion in the Cenomanian Limestone and the most satisfactory
exposure of the planus Zone of the Upper Chalk in Devon. Much of the
interest of the area has arisen from a massive landslip in the mid
nineteenth century when a large field became detached from the main
cliff and moved seawards. This cliff area, now called Goat Island,
and the chasm left when it moved, have largely become covered with
woodland and scrub. A continuing series of minor slips has given an
area of varied topography as well as exposing fresh areas for
colonisation. The climate is typically western Atlantic and the
frequent damp mists encourage a profuse, vigorous growth of ferns
and climbers.
The woodland here is varied:
photographic records establish that
much of it has developed since 1905, and all ages of tree from that
date are present. Some areas have regenerated naturally, such as the
chasm between Goat Island and the mainland where ashwood has
developed, whilst others have been planted. The main species in the
planted areas include beech, ash, holm oak and Turkey oak, silver
fir and pines. Extensive areas of the reserve are covered by a
mixture of ash and field maple with a thick understorey of hazel,
dogwood, spindle, blackthorn and other scrub species. The whole area
is a mosaic of developing woodland and scrub together with abundant
climbers, traveller's joy and ivy featuring prominently.
The ground flora varies
in luxuriance depending on tree cover,
ranging from areas dominated by ivy with abundant clumps of PhylKtis
scolopendrium to almost open grassland where scrub is just
developing. Species present in some abundance include Mercurialis
perennis, Circaea lutetiana, Geranium robertianum, Carex pendula,
Rubus fruticosus agg., Dryopteris filix-mas, D. dilatata and
Polystichum setiferum together with the usual mesophilous herbs. A
feature of some areas is a low scrub with much Rubus fruticosus
agg., Ligustrum vulgare and Rubia peregrina. In proximity to this
vegetation Lithospermum purpurocaeruleum is found.

6 ha
Grade i
Black Tor Copse is on the
northern edge of Dartmoor but having
similarities to the Wistman's Wood situation in that the area has
developed over a granite clitter on the northwest-facing slope of
the valley of the West Okement River. Pedunculate oak is again the
dominant species but the trees are taller and it is possible to walk
beneath much of the canopy. A rich and luxuriant epiphyte flora is
present containing several species such as Antitrichia curtipendula
and Douinia ovata which are of local, northern or western
distribution. The ground flora contains acidophilous species such as
bilberry together with grasses and ferns growing in crevices and on
patches of soil. The majority of the granite blocks are covered with
a carpet of bryophyte species such as Rhytidiadelphus loreus,
Thuidium tamariscinum and Plagiothecium undulatum. See also L-92,

W.63- BOVEY
VALLEY AND YARNER WOODS, DEVON
sx 7778.
385 ha
Grade i
This woodland complex is
one of the richest and most varied
remaining in the Dartmoor National Park. The many different
conditions of slope, aspect, and soil, together with the Atlantic
climate, support a very rich and varied flora and fauna.
The woods lie in the valleys
of the River Bovey and some of its
tributary streams on the eastern fringe of Dartmoor. Included are
Rudge Wood, parts of Houndtor and Hisley Woods, Water Cleave,
Woodash, Wanford Cleave, Lust-leigh Cleave and Neadon Cleave, all in
the main Bovey Valley, and the lower slopes of the valley of the
Becka Brook, together with Yarner Wood to the south and the smaller
detached block of Higher Knowle Wood to the east. Considerable parts
of the site are already managed as the NNRs of Yarner Wood and Bovey
Valley Woodlands.
Yarner Wood includes the
valleys of the Yarner and Woodcock Streams,
together with the intervening spur of land, giving an altitudinal
range of 240 m. The tree canopy is composed mainly of sessile oak,
with birch locally on the sites of old fields. There are also
plantations of Scots pine and other conifers, and much planting of
oak and other hardwoods has been done since the Reserve was declared
in 1951. The wood is similar in character to some of the Welsh
woodlands, but is generally drier, and some of the oaks are much
larger than those typical of western British woods nowadays. Holly
and rowan form an understorey, which is locally dense, and the
ground flora of the drier slopes is dominated by bilberry, bracken,
heather and Melampyrum pratense. The rare Lobelia wens is associated
with some of the old field sites.
In the valleys, on better
soils, ash and alder are frequent, with
hazel below, over a mesophilous ground flora including such species
as Primula vulgaris and Sanicula europaea. Osmunda regalis and
Chrysosplenium oppositifolium occur locally, together with good
epiphyte and bryophyte floras including such sensitive species as
Hookeria lucens.
The main block in the Bovey
Valley carries a variety of woodland
types, including those already described. Whereas Yarner Wood is
entirely on Culm rocks, however, much of this area is on granite,
giving relatively base-rich soils often littered with granite
boulders. On the lower slopes, bluebell and Holcus may dominate the
field layer, with a mixture of ferns and Oxalis acetosella on
flushed areas. Pedunculate oak replaces sessile oak, and ash, alder,
birch and beech are all frequent over a relatively calcicolous field
layer. The granite boulders in and near the river and the Becka
Brook carry a very rich bryophyte flora.
Higher Knowle Wood, to
the east of the main block, lies on an
unusual conglomerate rock which is probably related to the nearby
Bovey Beds (Oligocene). Pedunculate oak is the main tree, but beech,
ash and many others also occur.
The fauna of the whole
complex is characteristically western, with
such birds as the dipper, grey wagtail and pied flycatcher.

Grade 2
The site occupies the two
arms and junction of a Y-shaped valley
system on the south-west edge of Dartmoor. Sessile oak woodland is
present over much of the site but on the east and south-west beech
has been planted. The beech is gradually becoming dominant and a
successional series is exhibited. The ground flora is for a large
part a grassy sward containing species such as Holcus mollis, H.
lanatus, Anthoxanthum odoratum, Potentilla reptans, Endymion non-
scriptus and Pteridium aquilinum. There is a good epiphyte and
bryophyte flora, the latter being particularly rich in the vicinity
of the streams.

165 ha
Grade 2
Heddon Valley is an unspoilt,
steep-sided, straight valley leading
down to the sea. The valley runs north-south and the woodland is at
the landward (south) end. Included in the site is open, grassy
moorland, damp meadowland on the valley floor and scree slopes at
the seaward end of the valley. The woodland is dominated by sessile
oak with some patches of ash. A wide range of tree and shrub species
are present including alder, birch, beech, hazel, hawthorn, holly,
traveller's joy and gorse. The field layer is varied and includes
both basiphilous and acidophilous communities. There are areas
containing dog's mercury, primrose,
Fragaria vesca, Euphorbia
amygdaloides and Sanicula europaea which
may be contrasted with areas supporting communities which include
bilberry, heather, foxglove and bracken. Yet another facies
represented is the damp, fern-rich woodland type with Dryopteris
spp. abundant.

W.83- HOBBY
WOODS, DEVON
ss 3323.
90 ha
Grade 2
The Hobby is an area of
steep, wooded sea cliffs facing in a north-
easterly direction over Barnstaple Bay on the north Devon coast. The
tree dominant is sessile oak although within the woodland beech, ash
and some planted conifers are present. These other species occur on
the upper parts of the slopes, pure oak woodland being present on
the steeper slopes close to the sea. Shrub species are represented
by hazel, hawthorn, holly, blackthorn and gorse; some rhododendron
is present. Large areas of the ground flora are dominated by a sward
of Luzula sylvatica, other areas supporting a flora which includes
Ajuga reptans, Geranium robertianum, Fragaria vesca, Sanicula
europaea and Asperula odorata. A rich fern flora is present
including Dryopteris borreri, D. filix-mas, D. dilatata and D.
aemula. Epiphytes are well represented on the boles and branches of
the trees, their presence emphasising the moist conditions found
within this type of woodland.

W.64- HOLNE
CHASE, DEVON
3x7271.
290 ha
Grade i*
This is an extensive valley
system of the rivers Dart and Webburn on
the southern fringe of Dartmoor. Steep-sided valleys of nearly all
aspects are present with altitude ranging from 75 to 230 m. There is
a series of oakwoods, and sessile oak predominates in the area
particularly on the valley alluvial soils. The oak occurs with other
species such as ash, beech, small-leaved lime, hornbeam, aspen, wych
elm, holly, hazel and willow. Planted larch and Douglas fir are also
present. On the richer soils a mesophilous ground flora is to be
found containing species such as dog's mercury, primrose and
Sanicula europaea. The hillsides and more acidic soils support more
pure stands of sessile oak under which a field layer dominated by
bilberry, bramble, Luzula sylvatica and Lonicera periclymenum is
present. Throughout the area, flushes are to be found containing
much Chrysosplenium oppositifolium under an ash and alder canopy; at
their edges these merge gradually into the surrounding oak woodland.
At the uppermost edges of the valleys the epiphyte flora resembles
that of the woodlands higher on the Moor although the flora is less
varied. A point of particular note is the presence of a rich
bryophyte flora, both in the woodland and in the rivers themselves;
the very rare Fissidens poly-phyllus and F. serrulatus can be found
in some quantity near Holne Bridge.

W.79- PILES
COPSE, DEVON
sx 6361.

Grade 2
This is a valley woodland
on the southern edge of Dartmoor on the
west- facing slope above the River Erme. Although
strewn with boulders the
woodland floor does not exhibit such
extreme clitter formations as found in Wistman's Wood or Black Tor
Copse. The tree layer is again dominated by pedunculate oak but the
trees are less stunted and the appearance is of a more ordinary
woodland. The climate appears to be milder and more humid; there is
little or no Antitrichia or Douinia but Jamesoniella autumnalis,
Harp-anthus scutatus and Dicranum fiagellare occur, these not having
been recorded anywhere else in Devon.

4 ha
Grade i
This is a small area sited
on the west-facing side of the West Dart
river valley. The wood lies between 380 and 435 m on 'clitter', a
granite block scree. In contrast with many Dartmoor woodlands
pedunculate as opposed to sessile oak is dominant. The trees are
gnarled and twisted, many having their lower branches resting on the
granite blocks which form the woodland floor. There is some rowan, a
little hazel, holly and willow (Salix aurita). The epiphyte flora,
both bryophyte and vascular, is luxuriant and epiphytic lichens are
well represented. Antitrichia curtipendula is known to occur as are
many bryophytes with a western distribution such as Douinia ovata.
The ground flora consists of a bryophyte carpet covering the blocks,
and species such as bilberry, Luzula sylvatica, Holcus mollis and
bramble grow in soil-filled crevices. Ferns form an important part
of the ground flora.

A coastal woodland which
has a generally north-facing aspect. The
cliff slopes steeply and drops precipitously to the sea which forms
one boundary, whilst on the landward side the woodland is bordered
by moorland. The tree canopy is dominated by sessile oak, there
being a little rowan and birch. The rare Sorbus devoniensis and S.

yew, holly, sallow and rose mainly as understorey species.
The ground flora is for
the most part acidophilous with Vaccinium
myrtillus, Melampyrum pratense, Deschampsia flexuosa, Calluna
vulgaris and Erica cinerea being frequent. Some more base-rich areas
support Allium ursinum, Fragaria vesca, Sanicula europaea and

This ancient park is, for
its size, one of the richest sites for
epiphytic lichens known in Britain, due largely to its freedom from
air pollution and from disturbance. Interesting comparisons can be
made between the lichen flora of the south-western part, where
ancient trees of oak, alder, birch and willow are associated with
boggy ground in the valleys, and where there are also some ancient
ash and beech, and that of the northern part where many old elms and
other planted trees occur. Several of the lichens of the site are
not known to occur elsewhere in Britain.

Grade 2
This is the best remaining
example of the steep-sided wooded valleys
which run through boulder clay-covered Magnesian Limestone to the
coast in this region.
Two main types of Magnesian
Limestone of the Middle Series, Shell
Limestone Reef and Bedded Limestone, are exposed in cliffs up to 30
m high. The soils are derived from variable boulder clay and are
mainly alkaline but leaching of sandy soil produces acid conditions
locally.
Pedunculate oak and ash
occur together with some yew, elder,
hawthorn, hazel, rowan and rhododendron. The field layer is composed
mainly of Pteridium aquilinum, with Anemone nemorosa, Mercurialis
perennis, Deschampsia cespitosa, Holcus lanatus, Endymion non-
scriptus and Blech-num spicant. Festuca ovina occurs on the leached
sandy soils.
Beech has been planted
in some areas and sycamore has established
itself. There are also a number of mixed conifer plantations and
some plantations of hardwoods. Cypripedium calceolus and Ophrys
insectifera formerly occurred but are now thought to be extinct.
Other notable species still occurring are Pyrola rotundifolia and
Convallaria majalis.
The northern brown (Castle
Eden) argus butterfly Aricia artaxerxes
occurs here.

W.53- CANFIELD
HART WOOD, ESSEX
TL 5619.
30 ha
Grade 2
Canfield Hart Wood lies
close to Hatfield Forest on calcareous till.
It is transitional in character between the oak-ash coppice-with-
standards type widespread in eastern England, and the derived type
dominated by elm. The ground flora has abundant oxlip and where the
canopy is broken patches of grass occur. Many rare and local species
are present, including Iris foetidissima, and Campanula glomerata,
Anacamptis pyramidalis, Ophrys apifera, more characteristic of the
grassland.
The wood is selected mainly
as the southernmost population of oxlip.
This is a species on which much research has been carried out and
whose range-determining factors are not understood. This, coupled
with the wood's diversity, justifies inclusion as a grade 2.

W_55. EPPING FOREST,
ESSEX
TQ 4298.
1150 ha
Grade 2
Epping Forest stands on
London Clay overlain in places by gravel and
sands, giving rise to a mosaic of neutral and acid soils with
locally impeded drainage. Most of the woodland is ancient groves of
pollarded beech, some of coppice origin, with some pedunculate oak,
silver birch and holly. Hornbeam forms a separate woodland type with
some pedunculate oak, mainly on the lower-lying clays. Throughout
the Forest, birch and holly invade where there are gaps in the
canopy. Although the woodland is mostly overmature, all the dominant
species are regenerating sporadically, mainly on the margins of
mature woodland. The ground flora is poor, often absent completely
below beech and hornbeam, but along watercourses and beside ponds a
marsh flora has developed. Epiphytes are much reduced by air
pollution and shade.
This site represents both
beech and pedunculate oak-hornbeam
woodland but in view of pollution and public pressure the site is
not considered to merit grade i status.

W-52. HALES
WOOD, ESSEX
TL 5740.
8 ha
Grade 2
In east Cambridge, west
Suffolk and north Essex there is a series of
coppice-with-standards woodlands over an area dominated by Chalky
Boulder Clay. Hales Wood is a good example of such a woodland. The
canopy is dominated by pedunculate oak together with ash, field
maple, elm and hornbeam, the last forming an interesting link with
the concentrations of this species in the Home counties. There is a
wide range of shrub species present including hazel, hawthorn,
dogwood, blackthorn, rose, wayfaring tree and guelder rose.
The most characteristic
feature of the ground flora is an abundance
of the true oxlip. Other species dominant in the field layer include
Mercurialis perennis, Fragaria vesca, Sanicula europaea, Viola sp.
and, in the wetter patches, Filipendula ulmaria. The dewberry is
common in some parts of the wood whilst occasional small patches of
Paris quadri-folia may be found.

W-54- HATFIELD
FOREST, ESSEX
TL 5320.
360 ha
Grade 2
This former Royal Forest
lies mainly on Chalky Boulder Clay with
patches of gravel exposed near low-lying ground. Large oak, hornbeam
and horse chestnut occur in the open parkland, but most of the
woodland is coppice- with-standards from which many of the standards
have been felled. Ash, hazel and field maple are now the most
abundant species, with hornbeam and field maple standards. Within
the Forest as a whole there are also ponds and streams. A wide
variety of plants occur in the area, with Epipactis purpurata and
Paris quadrifolia among the local species present.
The site is included as
an example of eastern coppices with a
composition somewhat intermediate between the hornbeam and the ash-
hazei-maple coppices. It has the additional advantage that a variety
of habitats occur in a single location.

W-74- COLLINPARK
WOOD, GLOUCESTERSHIRE
so 7528. 65 ha
Grade i
Collinpark Wood lies on
clay soils sloping gently into the alluvial
plain of the River Leadon, and contains tributaries of this river.
It is an overgrown coppice woodland of up to about 40 years' growth,
dominated by sessile oak and small-leaved lime, with local
concentrations of silver birch and a few ash and poplar. Wild
service is also locally abundant and regenerating profusely. The
sparse shrub layer includes hazel, broom, crab apple and willows.
Soils are mostly heavy, neutral to acid. The ground flora has
abundant bluebell and dog's mercury and a range of species including
Galeobdolon luteum, Primula vulgaris, Pteridium aquilinum,
Deschampsia cespitosa, Carex pendula and Chrysosplenium
oppositifolium. Along the northern margin there is a massive
causeway embankment and associated moat. The latter is filled with
organic material with a fen-like flora, whilst the calcareous
subsoil brought to the surface on the embankment has enabled
calcicolous species such as wych elm, field maple and dog's mercury
to become established.
The wood is selected as
a representative of damp calcifuge lime
woodland in western Britain, complementary to the Lincolnshire lime
coppices, where, however, the oaks are almost entirely pedunculate.

W.J2. COTSWOLD
COMMONS AND BEECHWOODS, GLOUCESTERSHIRE
808913-9011.
740 ha
Grade i
Although there are many
fine stands of beechwoods in the Cotswolds,
the Birdlip-Painswick Woods are regarded as the finest example. The
high forest beech here varies in age from about 300 years downwards,
but the majority appear to be 150-160 years. The understorey of
holly and yew is sparse, and only locally forms a closed canopy.
Natural regeneration of beech, ash, holly and yew occurs, aided by
the recent thinning of some of the canopy. The field layer consists
mainly of Oxalis acetosella, Mercurialis perennis, Anemone nemorosa,
Sanicula europaea, Circaea lutetiana, Helleborus viridis and Daphne
laureola, but numerous other species have been recorded, including
Cephalanthera rubra, Monotropa hypophegea, Neottia nidus-avis,
Pyrola minor, Epipactis leptochila, E. vectensis, Convallaria
majalis and Aquilegia vulgaris. Common rights exist over the land
and this, coupled with the fact that the area carried beechwood in
the fourteenth century, suggests that the woodland here is primary.
The neighbouring woods
of Buckle, Witcombe, Cranham and Brockworth
are also dominated by beech with an admixture of ash. Some appear to
be of coppice origin. Holly forms the main understorey, but the
absence of old individuals suggests that it has invaded recently.
Within Cranham Wood is an open area, formerly grassland, now being
invaded by a considerable variety of trees and shrubs, including
beech, ash, yew, holly, hawthorn, whitebeam, hazel and oak. It
appears that this is developing towards 'mixed beechwood' and
constitutes an important variant of beech woodland.
The Sheepscombe Wood complex
is extensive and lies on both sides and
round the head of a valley above Sheepscombe. Although partly under
conifers, there are substantial areas of beech woodland containing
rare species. Together with Saltridge Hill Wood it is almost
contiguous with the Birdlip-Painswick Woods.
The Painswick Beacon area
is open grassland, scrub and small copses
surrounded by extensive beech woodland which is used intensively by
the public as an open space for recreation. The higher parts of the
Hill, particularly the flat plateau, are used as a golf course, on
which Erachy-podium pinnatum has been controlled by mowing. Many of
the grasslands accessible from the road are used as carparks.
The lower slopes of the
Hill are old quarry workings with typical
Cotswold grassland species, being well-known for the abundance of
musk orchids Herminum monorchis, pyramidal orchids Anacamptis
pyramidalis and fragrant orchids Gymnadenia conopsea. Colonisation
by subspon-taneous Scots pine has occurred in most of the old
quarries - in some places trees are 6-10 m tall. Seedlings are
widespread. Grassland is of the Brachypodium pinnatum-Bromus erectus
type with a little Festtica ovina, Koeleria gracilis and Briza
media. Cirsium acaulon is frequent, with good quantities of Lotus
corniculatus and Anthyllisvulneraria. Hieracium exotericum, which is
widespread on the open screes and quarry floors, is a feature of the
Cotswolds.
Juniper is uncommon, 12
bushes being found in 1968, most of them 30-
46 cm high, although three moribund 1.2-1.5 m examples were found in
mixed scrub under pine.

W-73. FOREST
OF DEAN, GLOUCESTERSHIRE
Grade I
The Forest of Dean, like
the New Forest, was a Royal Forest which
has survived as a large area of woodland. Although it has been
exploited, mainly for large timber, for centuries the woodlands have
been maintained by planting and careful management. In the past few
decades large areas of The Dean have been converted to conifers but
existing deciduous woodland still reflects differences in the
underlying rocks.
The central region lies
on Coal Measures from which a clay-loam soil
has developed and which carries oak (Quercus robur) woodland and a
poor, calcifuge ground flora. Surrounding this acid area are
limestone and Old Red Sandstone. These form more fertile soils which
bear a variety of woodland types over a richer ground flora. Oak
woodland, which is often pure but may contain birch and beech,
commonly grows over a bluebell, Holcus mollis and bracken field
layer. In the more acid areas this is replaced by bilberry, and in
the more base-rich areas by Sanicula europaea, Circaea lutetiana and
primrose. Woodlands on the limestone are often mixtures of oak,
beech, lime, ash and a variety of shrubs.
Conservation in the Forest
of Dean, like the New Forest, is best
effected by a broad agreement covering the whole of the Forest.
Among sites which together constitute a more or less complete range
of woodland types, the following are regarded as the most important.
See also W.g5.
(a) Nagshead Inclosure
so 6008. 28 ha
This area of mature, broad-leaved
woodland planted in 1814 lies on
the Pennant Sandstone (Coal Measures). The main species is
pedunculate oak with sweet chestnut, beech, birch and gean. The
western part, which has been closed to grazing since 1947-48, has a
developing and dense understorey of holly, rowan and other species
and some tree regeneration, but not of oak. The eastern part remains
open to grazing and has a sparse and scattered understorey of holly
and rowan.
The field layer is dominated
by Holcus mollis, Pteridium aquilinum
and bramble with Deschampsia flexuosa, Endymion non-scriptus and
Oxalis acetosella locally abundant.
This is a good example
of the older age class of Forest of Dean
oakwood on the Coal Measures. Since 1942 it has been the site of
important ornithological studies mainly in connection with a series
of nest boxes which totalled 238 in 1964. The four important species
breeding in the boxes are pied flycatcher, redstart, blue tit and
great tit. All these species nest here in some numbers and there are
no other nest box areas in Britain where so many pairs of pied
flycatcher and redstart breed. The study of the pied flycatcher is
the most prolonged ever made and only Wytham, near Oxford, has a
titmouse study of comparable size and duration. Recently a study of
the wood warbler has been started and almost the whole population of
adults and young have been ringed. There is nothing on a comparable
scale elsewhere in Britain.
(b) Dingle Wood so 5611.
9 ha
This woodland lies on Carboniferous
Limestone which has been
quarried in the past. The result is a series of deep pits and
gullies (or 'scowles') surrounded by irregular cliffs which have
been abandoned for long enough to allow woodland to develop
naturally. Part of the area has been planted.
The woodland consists of
a great variety of species with beech and
wych elm often dominant together with holly and yew in the shrub
layer. Other trees present include birch, sweet chestnut, ash, oak,
sycamore and rowan with a scattered shrub layer of holly and yew
together with field maple, dogwood, hazel, hawthorn, willows, elder,
roses and guelder rose.
The herb layer contains
a rich variety of calcicolous species with
Paris quadrifolia, Pyrola minor, Colchicum autumnale and Neottia
nidus-avis of particular note. A good calcicolous bryophyte flora
also occurs.
The woodland is particularly
notable for the richness of its tree,
shrub and herb layers and the scowles are floristically some of the
richest areas of the Dean Forest.
(c) Speech House so 6212.
18 ha
An area of open woodland
with very ancient oaks, beeches and
hollies. The soils are poorly drained acid loams and patches
ofjfuncus effusus occur. The ground flora is mostly a Pteridium-
Rubus carpet with large areas of Agrostis tennis grassland.
The combination of large
trees and open conditions has perpetuated
an outstandingly rich epiphytic flora and 53 epiphytic lichens and
15 epiphytic bryophytes have been recorded. The epiphytic flora is
one of the richest in central lowland England and is exceeded only
by that of some of the ancient parks, e.g. Moccas Park in
Herefordshire. Usnea spp. are now rare in the forests of lowland
central, north and east England but they are finely developed here.
Alectoria fuscescens is a species of northern (boreal) distribution
and the Parmelias, especially P. caperata, show a luxuriance not
otherwise seen in midland England. Per-tusaria hemisphaerica and
Thelotrema lepadinum are probably relic species of the old forests
as is P. flavida which is rare everywhere. Other relic species may
be Haematomma elatinum, once thought to be confined to south-west
Ireland and north-west Scotland, but now known in widely scattered
areas of Britain, and Normandina pulchella, formerly considered as
highly Atlantic.

W.75- HUDNALLS, GLOUCESTERSHIRE
so 5404, so 5303. 75 ha
Grade i
The wide range of semi-natural
coppice types in the lower Wye valley
area includes a series on the more acidic sandstone rocks in which
beech is the main constituent, even though other species are usually
mixed with it. Much of this woodland occurred on the Monmouthshire
side, where it has all, as far as is known, been allowed to develop
to high forest or, more commonly, has been replaced by a variety of
plantations. On the Gloucestershire side substantial tracts of these
calcifuge coppice types survived as coppice into the present
century, particularly to the north and south of the St Briavels
meander, and extending north to the Staunton area. Recently,
however, much has been cleared, notably at Lords Grove near
Monmouth, and north from Wyegate Hill, but one group, centred on
Hudnalls, remains virtually intact.
Hudnalls and adjacent woods
occupy steep, north- and west-facing
sandstone slopes. Much of the woodland is a mixture of beech and
sessile oak over a ground flora of Luzula sylvatica, Blechnum
spicant, Lonicera periclymenum and Melampyrum pratense. Part of this
is a mixture which retains the small-coppice structure, but other
parts on the steepest slopes are ancient beech high forest with very
few oaks and a negligible field layer. Along the stream sides and in
parts of the coppice, ash and small-leaved lime occur. All these are
on strongly acid soils, but where streams drain down the slope and
along flushed areas at the base of the slope a far richer coppice
type occurs in which wych elm, ash and hazel are more abundant and
the ground flora is extremely rich.
Hudnalls has a complex
management history. Part was common woodland,
but adjacent parts are coppice-with-68 Woodlands standards.
Structural differences coincide partly with walls within the wood
and are clearly a relict of use and management, but the composition
of the wood appears to be natural.

W.26. NEW FOREST,
HAMPSHIRE
su 20.
12 600 ha
Grade i*
This former Royal Forest
lies on Tertiary sands, gravels and clays
dissected by wide, shallow valleys. Its soil types encompass a
considerable range from relatively base-rich brown earths to
extremely acidic podsols, and from these to waterlogged clays,
alluvium and acidic peats in flushed and low-lying situations. Only
part of this area is wooded though the woods are extensive: within
the New Forest as a whole the tracts of grassland, heathland and
valley mire grade into woodland, forming a tremendous variety of
transitional habitats of scientific importance. The woodlands
themselves are partly unenclosed, these being known as the Ancient
and Ornamental Woodlands, and managed largely for amenity and nature
conservation, and partly within enclosures: the remainder, the
Statutory Inclosures, are mostly managed commercially, but include a
number of scientifically important sites.
The woodlands are of different
types. The most extensive are mature
and overmature stands of beech, pedunculate oak, sessile oak, and
any combination of these (though it is rare to find both oaks
together), with an understorey of holly and rarely other species
such as yew and hawthorn. Structurally these are diverse, with a
range of age classes from saplings to ancient, overmature trees,
many of which have been pollarded. Over some sites on base-rich
clays, ash and less commonly field maple are important constituents,
but hazel, formerly common, is now rare within the unenclosed
woodlands. The ground flora in the woodlands on acid soils is very
poor, often no more than patchy Leucobryum glaucum, but on the
deeper soils bramble and bracken may be abundant, and on base-rich
clays a fairly rich basiphilous flora may develop.
Less extensive woodland
types fall into four broad categories. In
valley bottoms with alkaline and neutral ground water, alder carrs
have developed, some with a rich, marsh flora including Impatiens
noli-tangere and the national rarity Lud-wigia palustris: many of
these have been coppiced until recently, but there are some with a
range of age classes, including very old trees. Scrub, dominated by
holly, but also including yew, whitebeam and hawthorn, has developed
on the better, reasonably well-drained soils, and is in many places
developing into a mixed woodland with pedunculate oak dominant. Self-
sown pinewoods occur on the more heathy areas and into areas of wet
heath. Birch woodlands, though not uncommon, are found mainly around
the margins of the larger stands of mature woodland.
The vascular flora of the
New Forest woodlands is, with few
exceptions, composed of widely occurring plants. Species of
biogeographical interest in addition to the two species mentioned
above include ferns such as Thelypteris phegopteris and T. palustris
which are local in southern England. It is the cryptogamic flora of
the New Forest that is extraordinarily rich. The bryophyte flora
includes some rare species, e.g. Zygodon forsteri. In recent surveys
over 180 species of epiphytic lichens have been recorded by F. Rose,
including numerous species characteristic of ancient woodland (e.g.
Lobaria pulmonaria), oceanic species reaching their eastern limit in
the New Forest (e.g. Sticta limbata), hyper-oceanic species formerly
thought to be confined to west Scotland, Wales or western Ireland
(e.g. Mycoporellum sparsellum), boreal species not otherwise found
south of north Wales, e.g. Alectoria subcana and
Pertusaria velata which
is now apparently extinct elsewhere in
Britain.
The New Forest woodlands
are of international importance. In the
lowland areas of north-west Europe, no area equals them in extent of
old woodlands, the number of overmature trees, the relative lack of
human interference over a long period, the invertebrate fauna and
the epiphytic lichen flora. The woods are also an important breeding
area for birds, with the honey buzzard and hobby as notable rare
species. The scientific importance of the New Forest lies mainly in
the unenclosed woodlands. The enclosed woodlands, with the exception
of two areas enclosed early and still retaining their ancient
woodland, are not so rich floristically although they have some
important features (e.g. Pulmonaria longifolia and Illecebrum
verticillatum in some rides). The Ancient and Ornamental Woodlands,
and to a lesser but still significant extent the Statutory
Inclosures, support a rich invertebrate fauna which is in many
respects unique in Britain. The groups particularly well represented
are the Heteroptera, Homoptera, Lepidoptera, Hymenoptera (Aculeata
and Symphyta), Diptera and Coleoptera. The fauna of dead and dying
wood is of especial importance. Although the greatest interest
naturally attaches to the insects associated with deciduous trees,
especially oak, the fauna of the conifers, particularly Scots pine,
is by no means negligible. This is a famous area for Lepidoptera and
contains the only British localities for the interesting insect
Cicadetta Montana.
The scientific value of
the unenclosed and ancient woods results in
part from their great extent and variety and therefore the selection
of areas of outstanding importance within the complex must be
carried out with caution. Present knowledge indicates that the
biologically richer sites within the complex include Vinney Ridge,
Mark Ash, Eyeworth Wood, Rufus Stone, Hollands Wood, Whitley Wood,
Denny Wood, Mallerd Wood, Linwood, Bramshaw Wood, and South Bentley
Inclosure.

W.27- SELBORNE
HANGER, HAMPSHIRE
su 7333. 95 ha
Grade i
Selborne Hanger lies on
the north-east-facing Chalk scarp
overlooking the western limits of the Weald. It consists of a pure
beechwood on a steep east-facing Chalk slope grading to Clay-with-
Flints on a plateau with a more mixed woodland. The beech is of
uniform age and 30 m tall, with a poorly developed shrub layer of
hazel and yew. The most abundant plants are dog's mercury, ivy and
bramble, with Sanicula europaea and Brachypodium sylvaticum locally
abundant. The plateau is wooded common land with oak and ash, hazel
and hawthorn over a field layer of Rubus fruticosus-Galeobdolon
luteum. (Selborne Hanger is associated with Gilbert White.)
Selborne Hanger should
be considered with Noar Hill (L-5o) and High
Wood Hangers. These are not contiguous with Selborne but lie on the
Chalk scarp about a kilometre to the south. Within this beechwood
there is almost a complete range of aspects. The beech is uneven
aged, but casts a dense shade which has allowed only local
development of an understorey. Here yew is common, but many species
are confined to the wood margin. Mercurialis perennis, Sanicula
europaea, Galium odoratum and Hedera helix are the most abundant
field layer species.
Noar Hill has the advantage
that it is adjacent to floristi-cally
rich chalk grassland, whereas Selborne has the additional plateau
woodland feature.

W.I24- BRAMPTON BRYAN
PARK, HEREFORDSHIRE

60 ha
Grade 2
Brampton Bryan Park lies
at the northern end of Renword-ine Hill on
steep east-, west- and north-facing slopes across a geological
transition between Old Red Sandstone and Silurian strata. The
woodland is ancient open oak parkland with sweet chestnut, beech,
ash and holly, with an area of wych elm woodland above a vestigial
dog's mercury field community. The ancient woodland is extremely
rich in epiphytic lichens.
The biological richness
of Brampton Bryan Park has been recognised
only recently. It is clearly very similar to Moccas Park and its
epiphyte flora is at least as rich but the invertebrate fauna has
not received a similar degree of study. (See Appendix.)

W.I26. BUSHY
HAZELS AND CWMMA MOORS, HEREFORDSHIRE
302851.
30 ha
Grade 2
This site lies c. 3 km
from the Radnor border on a level and damp
site, with loamy soils derived from Lower Old Red Sandstone rocks.
Ash is most abundant in the canopy though coppiced wych elm is often
co-dominant. Pedunculate oak and birch associate with them in
varying amounts though these are completely absent in some parts. A
stream divides off Bushy Hazels, a pure hazel coppice in the north-
eastern corner. The understorey and shrub layers are not well
developed throughout but the field layer is herb rich. Beneath the
hazel coppice are Deschampsia cespitosa and Endymion non-scriptus
with patches of Paris quadrifolia. In the ash-elm woodland, E. non-
scriptus, Anemone nemorosa, Mercurialis perennis and D. cespitosa
are predominant with Circaea lutetiana and Sanicula europaea. Wetter
patches contain Filipendula ulmaria, Chrysosplenium oppositifolium
and Carex pendula.
This site may be considered
alternative to Hill Hole Dingle, i.e. it
is an example of a mixed deciduous woodland on the Welsh borders. As
it has been heavily managed in the past, fewer native woody species
are present and the field layer is not as herb rich. The Dingle also
has more variety in its micro-habitats.

W.I25- DOWNTON
GORGE, HEREFORDSHIRE
so 4373. 55 ha
Grade 2
The ravine below Downton
Castle is wooded for a distance of over 2.4
km. The river has cut a deep gorge through Silurian rocks leaving
soils of an acid to weakly calcareous character. At higher levels
the woodland is mainly dominated by sessile oak, with a field layer
of Luzula sylvatica, but at lower levels a mixed deciduous woodland
occurs with ash and wych elm dominant. There is a wide range of age
classes, and one cliff has an old holly-ash-wych elm wood with a
vigorous colony of Festuca altissima. This is a sheltered site which
at lower levels is very rich in bryophytes, including Plagiopus
oederi, Pohlia cruda and many oceanic and submontane species. The
epiphytic lichen flora, though not inspected yet in detail, is
already known to be rich, with a fine colony of Lobaria pulmonaria,
Graphina anguina on holly and Peltigera horizontalis.

W.Il6. HALESEND
WOOD, HEREFORDSHIRE
so 7449.
55 ha
Grade i
Halesend Wood lies largely
on a Silurian limestone ridge near the
northern end of the Malvern Hills. The woodland is coppice and
coppice-with-standards in which sessile oak, hazel and common lime
are the most abundant species but many other native tree and shrub
species are frequent throughout the northern half of the wood,
notably yew, wild service, field maple and ash. The southern end,
whilst retaining the mixed deciduous character to some extent, has a
high proportion of birch and ash. The ground flora is of the rich,
basiphilous type, dominated by dog's mercury, bramble, wood anemone
and bluebell, with local areas of Allium ursinum. Certain local
forbs are common, including Campanula trachelium, Platanthera
chlorantha, Lathraea squamaria and Narcissus pseudo-narcissus.
Although hybrid lime is
one of the more abundant species here, it is
intimately mixed with other tree and shrub species and occurs as
coppice and ancient pollards. This unusual condition, and a number
of old quarries, add to Halesend Wood's value as a representative of
the rich, calcicolous woodlands of the south-west Midlands.

W.IlS. HILL
HOLE DINGLE, HEREFORDSHIRE
so 5354.
40 ha
Grade i
This is the steep-sided
valley of the Humber Brook, about 1.6 km
long, and cut through Old Red Sandstone. At its upper end the slopes
are boulder strewn. The sides are wooded and undisturbed and a
miniature alluvial plain bears ash-alder wood and willow carr. Ash
is the most abundant species on the valley sides but sessile oak and
elm are co-dominant in some areas. Birch, field maple and beech are
also present. Shrubs include hazel, hawthorn, elder and blackthorn.
The field layer illustrates the downwash of bases that has occurred;
and varies from a community dominated by Deschampsia cespitosa with
abundant primrose in upper, more open areas, through bluebell,
bramble or wood anemone to dog's mercury. Flushes with Chryso-
splenium oppositifolium and the rarer C. alternifolium are common.
Also of great interest are large patches of Helle-borus viridis.
Bryophytes carpet tufa springs, rock outcrops and rotting logs.
Flanking the woodland are more open areas of bracken and gorse.
This has been chosen to
represent a rich mixed deciduous woodland
type characteristic of the west Midlands. It also has a range of
wetland habitats within this small area and has the added advantage
of being undisturbed. (See Appendix.)

W.Iiy. MOCCAS
PARK, HEREFORDSHIRE
SO 3442.
140 ha
Grade i
Moccas Park is an ancient
deer park lying on north-facing slopes of
Old Red Sandstone, with flat ground below. The lower areas are
occupied by open, ancient park woodland with pedunculate oak and
sweet chestnut growing from an old grassland sward. On the higher
slopes the woodland is less open and richer in species, including
small-leaved lime, large-leaved lime, wych elm, field maple, holly,
beech, yew and ash, with a number of ancient specimens of exotic
trees, notably horse chestnut, sweet chestnut, and sycamore. The
field layer, which is heavily grazed in places, has abundant bracken
and other species of dry, mildly acid soils, such as foxglove,
bluebell and bramble, and patches of dog's mercury. The bryophytes
and epiphytic lichens are extremely rich, over 100 species of the
latter having been recorded recently by F. Rose. The fauna has been
relatively well studied, and is outstanding for Coleoptera, three
species being known nowhere else in Britain, namely Pyrrhidium
sanguineum (Cerambycidae), Hypebaeus flavipes (Malachiidae) and
Ernoporus caucasicus (Scolytidae).
Existing information clearly
suggests that Moccas is the best
ancient park wood in the Midlands, but other sites have been so
little studied that some may be of equal merit. Furthermore, recent
ploughing and fertilising of the grassland may have damaged its
ecological value. Brampton Bryan Park (W.I24) is at least as rich in
its lichens and can be regarded in this respect as an alternative
site but its Coleoptera have not been properly studied.

Wormley Wood and in the east Hoddesdon Park Wood. Much of the
intervening woodland has been recently felled and replanted with
conifers but broad-leaved trees and patches of broad- leaved
woodland still occur throughout. Part of the outstanding interest of
the area lies in its large extent, which provides for a greater
variety of woodland habitats and also for areas of scrub and rough
grassland.
Wormley Wood lies mainly
on the London Clay but there are also
gravel deposits. The varied geology and former land-use have
produced a mosaic of vegetation. Sessile oak is the principal
standard species over a coppice of almost pure hornbeam, but there
is a proportion of other tree species including ash, pedunculate oak
and birch. There are also some areas of high forest structure with
standards of both oak and hornbeam. The ground flora consists
largely of communities dominated by bramble, wood anemone, bluebell,
Luzula sylvatica and Lonicera periclymenum with bryophyte carpets of
Dicranum majus on fairly acid areas under standards. On more
calcareous areas the field layer is richer with Galium odoratum,
Galeobdolon luteum, Mercurialis perennis and Carex pendula: such
areas tend to have a high proportion of ash in the canopy. Within
the site there are areas of hawthorn and blackthorn scrub and
birchwood on old field sites. The wood is crossed by a small stream
along which alder has developed.
Hoddesdon Park Wood is
mainly high forest although there are areas
of coppice. The oak is well grown and there is a wide range of
sizes, including oak saplings and seedlings. Indeed the abundance of
oak regeneration throughout this woodland complex is one of its
interesting features. The more open canopy produces a ground flora
richer in species of both vascular plants and bryophytes than the
dense coppice areas. There is also a good variety of epiphytic
species including a community of Dicranum spp. (montanum, flagellare
and strictum) which occurs on the Continent.

The royal forest of Rockingham
once comprised an extensive tract of
semi-natural coppices, some of which were in large, continuous woods
many thousands of hectares in extent. These have now been fragmented
by clearance and opencast mining, and most of the surviving woods
have been converted to plantations. Of the remaining stands of semi-
natural woodland, only the former Purlieu Woods at the north-eastern
extremity of the forest are of outstanding importance. These formed
one continuous woodland until the mid nineteenth century when the
clearance of the western half of Thornhaw Woods cut the woods into
two main blocks, Bedford Purlieus to the east and Easton Hornstocks
to the west.
These woods lie mainly
on Jurassic limestone covered in places by
clay drift with patches of sand. Thus, although the soils tend to be
calcareous and poorly drained, there are appreciable areas of freely
drained soils of a variety of texture, and some tracts of acidic,
sandy soils. The coppice in consequence includes a wide range of
types including lime coppice on soils which are appreciably more
calcareous than most of its eastern locations, ash, hazel, wych elm,
maple coppice on calcareous clays, birch and poplar groves, sessile
oak-hazel coppice on acidic sands, valley Ulmus procera woodland and
extensive areas of sycamore invasion.
Bedford Purlieus is clearly
the most important part of the group.
Structurally it is very limited, having been clear-felled in recent
decades and partly replanted. Its outstanding feature is its
assemblage of herbaceous species (over 450 species of vascular
plants have been recorded), which include Euphorbia lathyrus, a
species of national rarity, Melica nutans at the southern edge of
its range, and E. amygdaloides towards its northern limit. Within
this wood both calcicolous and calcifuge species occur together with
those found more commonly in northern and western woodlands,
including Galium odoratum, Melampyrum pratense, Platanthera
chlorantha, Allium ursinum, Conval-laria majalis, Aquilegia
vulgaris, Ophrys insectifera, Blechnum spicant, Paris quadrifolia,
Luzulasylvatica, Atropa belladonna and Serratula tinctoria. On the
grounds of this floristic richness, Bedford Purlieus has been
described as one of the most important woods in Britain.
The fauna is also rich,
and although it is still relatively unknown,
it is regarded as the richest locality in this part of the east
Midlands. Among the butterflies recorded are the white admiral,
pearl- bordered fritillary, the silver washed fritillary, the
dark green fritillary, high brown fritillary, chequered skipper,
brown hairstreak, and white-letter hairstreak. Numerous local moths
have been recorded here. It is an isolated east Midland locality for
both the palmate newt and the adder.
Coppicing has now stopped
entirely in the group. Part of Collyweston
Great Wood has become a plantation whilst the centre was cleared for
an RAF establishment. A large quarry occupies the centre of Easton
Hornstocks. Part of Wittering Coppice has been converted to a poplar
plantation. Substantial areas of Bedford Purlieus have been
replanted with oak, beech and a variety of conifers, and other
sections have been destroyed by quarrying and military needs in
wartime. Despite all this, substantial areas of semi-natural
woodland exist in all four component woods of the site.

45 ha
Grade i
The woodlands of Castor
Hanglands NNR straddle a zone of marked
geological variety in Jurassic rocks, ranging in north-south
sequence from limestone to clay, cornbrash, sand and then clay
again. The soils reflect this sequence with a range from calcareous
loams to calcareous and neutral gleys. Most of the woodland was
formerly coppice-with-standards, most of which has been removed,
leaving a mixed ash-pedunculate oak woodland, with hazel, privet,
dogwood and spindle. On wetter soils, large ash stools occur with
hazel, willow and aspen. Part of Moore Wood, also in the reserve, is
high forest pedunculate oak. Corresponding with the soil variation,
a wide range of field layer types occur; Rubus fruticosus is locally
dominant, but Mercurialis perennis-Endymion non-scriptus is the most
widespread type, with Primula vulgaris, Anemone nemorosa, Lonicera
periclymenum and Euphorbia amygdaloides. Paris quadrifolia, Oxalis
acetosella and Allium ursinum occur on the wetter soils. The rides
and clearings are kept open and this encourages the rich
invertebrate fauna.
The woodlands are a good
example of oak-ash woodland, but their most
important feature is that they constitute part of a complex of
habitats on a range of soil types in a relatively small area.

260 ha
Grade i
The NNR of Holme Fen lies
partly on the site of the former
Whittlesey Mere. After drainage, part of the area was used for
agriculture and later abandoned. Since then, extensive birchwoods
(both species) have developed, which now constitute the finest
development of this type of woodland in lowland Britain. Other tree
species are present (oak, alder, willow and pine) in some areas, but
in general the birch woodland is remarkably pure. Another feature,
which is particularly valuable for experimental research, is the
fact that stands of different ages are present, covering almost the
entire life span of birch.
The area is additionally
interesting as a relict location of raised
mire species, including Sphagnum sp. and Calluna vulgaris. A recent
survey has shown that Holme Fen is exceptionally rich in fungus
species, including Naucoria langei which has been added to the
British list.
Excavations for a new pond
to supplement the existing duck decoy are
well advanced. When completed this will be an important feature of
the reserve and of the area generally.

W-42. MONKS
WOOD, HUNTINGDONSHIRE
TL 2080.
157 ha
Grade i
Centred on the Oxford Clay
dip slope on the edge of the Fens, Monks
Wood embodies the typical features of ancient woodlands of the
Huntingdon area. It is predominantly an ash-pedunculate oak wood
with local dominance of elm. It has been managed as coppice-with-
standards, but in recent decades the system fell into neglect and
the big timber was largely extracted and not replaced. A wide range
of tree and shrub species occurs, including maple, aspen, wild
service, birch
(both species), hawthorn (both species and hybrids),
many willows, hazel, guelder rose, wayfaring tree, spindle, privet,
blackthorn and dogwood. The ground flora is extremely rich, ranging
from dog's mercury on the well-drained sites to Filipendula ulmaria
on the waterlogged areas, and diversified by the presence of rides,
streams, ponds, overgrown old fields and small glades. Oxlip is
absent although primrose is common: Monks Wood is evidently just
outside the tolerance of oxlip. Recently, the management has
partially restored the coppicing cycle, and with it the herb
richness associated with the years following cutting. In addition to
its floristic richness, Monks Wood has long been famous
entomologically. Among the species for which it is noted is the
black hairstreak Strymonidia pruni, which was first collected here
in Britain, but the purple emperor has not been seen for some years.
In certain years there is a large breeding population of woodcock,
and the wood is still a good locality for the nightingale.

140 ha
Grade i
Lying on steep Chalk slopes,
these woods have soils 30-60 cm deep of
calcareous loam with few Chalk particles and a high siliceous
fraction. They consist of mixed coppice of ash and pedunculate oak
with some hornbeam, hazel and field maple, and only a few poorly
grown standards of pedunculate oak. Beech is rare and entirely
confined to the margins. The flora is very rich. Sladden Wood,
probably the best single site within the group, includes Orchis
purpurea, Ophrys insectifera, Cephalanthera damasonium, Neottia
nidus- avis, Platanthera chlorantha, Paris quadrifolia, Helle-
borus viridis, Mercurialis perennis, Sanicula europaea, Adoxa
moschatellina, Campanula trachelium, Ranunculus auricomus, Galium
odoratum, Pimpinella major, Angelica sylvestris, Deschampsia
cespitosa and Veronica montana.
The significance of these
sites is that almost everywhere else on
Chalk scarps the woodland is dominated by beech over a thin soil:
possibly the Alkham Valley Woods lie on a relict soil type.

W-5- ASHOLT
WOOD, KENT
TR 1738.
70 ha
Grade i
Asholt Wood lies on gently
undulating ground at the foot of the
Chalk escarpment. Springs rising at the base of the Chalk flow
through the wood. The soil, developed from Gault Clay and downwash
from the Chalk, is highly calcareous but poorly drained. Its texture
varies from heavy clay to clay loam, and small elevated areas appear
to be neutral or mildly acid in reaction. Structurally the wood is
mostly pedunculate oak standards over a range of coppice types, much
neglected for the most part, but in places recently coppiced after a
period of neglect. Much of the coppice is ash and hazel with some
maple, dogwood and willows, but on the apparently acidic knolls,
there is some hornbeam-ash coppice, and along the flood zones beside
the streams a mixed coppice of alder, ash, maple and hazel has
developed. The ground flora is rich, but no nationally rare species
have been recorded.
This site is selected as
a south-eastern counterpart of the chalky
boulder clay coppices of East Anglia and the Midlands. It differs
from them in having valley alder coppice, and lacking oxlip Primula
elatior and Geum rivale. Other examples of this type are known, and
one - Ryarsh Wood, Kent - has a richer flora, but Asholt is regarded
as the best example because it has a canopy largely free of aliens,
and is contiguous with a chalk grassland site (L.I5).

W.I. BLEAN
WOODS, KENT
TR 1060.
305 ha
Grade 1
The Blean forms the most
extensive area of nearly continuous
woodland on the London Clay in south-eastern England. Within this,
Blean Woods National Nature Reserve (NNR) forms a typical example.
The whole area has a long-standing
tradition of management as
coppice- with-standards with sessile oak as the dominant standard.
Sessile oak coppice, mixed in part with beech, occurs in a large
area on the western boundary, whilst the latter is dominant in a
very small central area of open high forest. Hornbeam coppice
dominates the northern parts and sweet chestnut coppice dominates
the south-central and south-eastern parts and much of Crawford's
Rough. Rowan is widespread whilst wild service and aspen are
becoming increasingly common in the newly coppiced areas. Alder and
guelder rose are also widespread. Along the southern parts of the
wood the London Clay is overlain by two patches of recent 'head
gravel', part of the terrace of an ancient valley floor of the Great
Stour River. This acidic gravelly drift supports dense chestnut
coppice with a honeysuckle, bluebell and Luzulapilosa field layer. A
small area of ash coppice with pedunculate oak and hazel has a
ground flora of Sani-cula europaea, Euphorbia amygdaloid.es and
Ajuga reptans. Also in the south-east part of the wood are acidic
areas with Calluna, Carex binervis, C. ovalis, C. demissa, Molinia
caerulea, Sieglingia decumbens and Dactylorchis maculata, all rare
in north-east Kent where heathlands are scarce. The areas of
recently coppiced oak-beech- hornbeam woodland have a rich ground
flora which includes Luzula sylvatica, Teucrium scorodonia, Milium
effusum, Melica uniflora, Lathy-rus montanus, Hypericum pulchrum,
Sarothamnus scoparius and Ruscus aculeatus. In the more dense old
hornbeam coppice Crataegus oxyacanthoides is an occasional associate.
The Blean has been a well-known
haunt for entomologists since the
latter part of the last century. It was originally scheduled to
preserve one of the few remaining colonies of heath fritillary
Melitaea athalia, the larvae of which feed on Melampyrum pratense.
This plant flourishes particularly in the light phase of coppicing
and along ride margins and is again plentiful in the Reserve. As a
result, for example during early July 1969, following coppicing,
this butterfly was a common sight in the open areas of the wood.
Recent studies in the Reserve have revealed a wealth of rare species
of a wide range of invertebrates. The wood ant Formica rufa is
abundant in parts of the wood and some 15 species of myrmicophilous
beetles have been found in its nests. A number of rare staphylinid
beetles have been found in the wood including Gyrophaena joyioides
(only known British locality), Borboropora kraatzi (first British
record for over 100 years) and Staphylinus fulvipes which is quite
common locally. Acritus homoepathicus (Coleoptera, Histeridae) is
abundant in fire sites in the coppiced areas. The millipede
Polyzonium germanicum, which has its British distribution almost
restricted to Kent, is common in the Reserve, as is Choneiulus
palmatus, another millipede more commonly recorded from greenhouses
and gardens. Among an impressive list of Heteroptera bugs is
included Charagochilus weberi (Miridae), a species new to Britain.
The large area of woodland of The Blean provides a stepping stone by
which many continental species enter the British Isles and become
established.

Grade i
This is part of an extensive
tract of woodland, scrub and grassland
on the Chalk scarp and plateau of the North Downs all of which is of
considerable scientific importance. Crookhorn Wood itself is a
mature beechwood with ash and field maple in the canopy, and an
understorey of yew. Structurally it is diverse, with a mixture of
age classes, including some very old trees, forming a closed canopy.
The humus lies deep over a shallow soil, and the ground flora,
though sparse, includes Cephalanthera damasonium, Neottia nidus-avis
and Daphne laureola. On the plateau over Clay-with-Flints the
woodland is mainly pedunculate oak with some coppice of hazel, ash
and sweet chestnut. Parts of the adjacent grassland have been
invaded by scrub in which ash is (unusually) rare and the most
abundant species are whitebeam, silver birch and dogwood, with
patches of yew. Within this scrub Helleborusfoetidus, Aceras
anthropophorum and a fine colony of Orchis purpurea are known.
The woodlands on Wouldham-Detling
Escarpment are similar but contain
serai ashwood as well as the range of types present in Crookhorn
Wood.

Grade 2
Ellenden Wood is part of
the ancient Blean Woods lying on London
Clay and spreads of gravel drift. Within the one block of woodland
are a number of woodland types. Coppice-with-standards of sessile
oak, with rowan, holly and wild service occurs over a field layer
dominated by Luzula sylvatica and Melampyrumpratense. Parts have
been planted with sweet chestnut, managed as coppice. A small
plateau area of clays has blackthorn, hornbeam and hazel with a
neutral ground flora. Hornbeam coppice with some oak standards (both
species) occurs on another area of clay with a predominantly
calcicolous ground flora. Valley sides have local woodland types,
including high forest of oak and beech, and of small-leaved elm, ash
and crab apple. Taken as a whole the flora is extremely rich, with a
wide ecological range, including heather and Galeobdolon luteum.
This site is close to and
comparable with Blean Wood. Botanically,
there is probably little to choose between the two, but Blean Wood
is better known zoologically and is therefore chosen as the grade I
site.

W.2. HAM
STREET WOODS, KENT
TR 0034.
210 ha
Grade i
These woodlands, parts
of which are NNR, lie on the plateau, slopes
and valley bottoms over Lower Weald Clay. Structurally they are
coppice-with-standards throughout, although there is a wide range of
coppice types. The standards are oak (mostly Quercus robur, but with
about 10% Q. petraea) with a proportion of birch (mostly Eetula
pubescent) which has entered as a weed species following the cutting
of the coppice. Wild service, gean and aspen also occur as 'weed'
standards.
Four types of coppice occur
on the plateau areas. These, defined by
their dominant species, are clearly the product of past management.
Hornbeam coppice is the most widespread, some of the stools being
massive indicators of the long history of such coppice on at least
part of the site. Hazel coppice occurs mainly on the valley slopes.
Chestnut coppice, still actively worked, occurs mainly in the
northern block. Oak coppice occurs in Carter's Wood, but has
evidently arisen from the felling of standard oaks. Other shrub
species occur within these types, including willows (Salix
atrocinerea and S. capred), both hawthorns and holly. The presence
of midland hawthorn as well as wild service is circumstantial
evidence that at least parts of Ham Street Woods are primary.
The woodland is diversified
by the presence of valleys and rides.
The former, which contain the richest areas floristic-ally, have ash
and alder woodland, worked as coppice, with midland hawthorn and
elder.
The ground flora develops
and changes cyclically as coppicing
proceeds, being least developed as the coppice becomes dense.
Although the proposed future management of large areas of the
woodland is of coppice-with-standards, much of the present wood is
old, neglected, hornbeam coppice in which the ground flora consists
of wood anemone, primrose, bluebell and honeysuckle. In the gills
dog's mercury is locally dominant. Where the canopy is more open
bracken and bramble are abundant. Rides in the north have heather,
gorse and Potentilla erecta, indicating acid conditions which
contrast with the base-rich nature of the valleys. The bryophyte
flora, which includes such noteworthy species as Eucalyx hyalinus,
Rhytidiadelphus loreus and Hylocomium brevirostre, supports the
conclusion that woodland has been continuous on this site.
Ham Street Woods have long
been famous entomologically.

This site lies on a plateau
of chert gravel derived from acidic
Hythe Beds giving rise to a podsolised soil, falling to a valley in
which first brown forest soils then calcareous soils derived from
Kent ragstone and base-rich peaty soils occur in an apparent catena.
Corresponding with this are four woodland types, respectively (i)
sessile oak high forest and coppice over Vactinium myrtillus-Calluna
vulgaris-Blechnum spicant, with Luzula sylvatica and Pyrola minor
locally; (2) sessile oak high forest with birch and holly with a
transitional ground flora of Endymion non-scriptus, Rubus fruti-
cosus, Pteridium aquilinum, Euphorbia amygdaloides, and Primula

field maple, ash, hazel and wych elm with a ground flora indicative
of base- rich conditions, including Mercurialis perennis, Sanicula
europaea, Galium odoratum, Helleborus viridis, Lathraea squamaria,
Listera ovata and Adoxa moschatellina; and (4) alder carr with
Chrysosplenium oppositifolium, C. alternifolium, Carex strigosa and
Equisetum telmateia.
With this exceptional range
of habitats, the vascular flora is very
rich. Both rowan and common whitebeam are present in the sessile
oakwood, together with the hybrid. Numerous bryophyte and lichen
species are recorded.

440 ha
Grade i
The woodlands on this south-west-facing
scarp slope of the North
Downs are extremely variable. They include almost the entire range
of types associated with the Chalk scarp and Clay-with-Flints
plateau sites. On the plateau, pedunculate oak woodland is prevalent
over coppice which is partly of sweet chestnut, but mostly a mixture
with hazel, ash and hawthorn. The field layer includes the range of
communities from Mercurialis perennis-Sanicula europaea, through
Endymion non-scriptus to Rubus fruticosus and Deschampsia cespitosa.
The thin rendzina soils on the slopes bear beech woodland in part,
and mixtures of ash, yew and hazel, over a discontinuous field
layer. At the south-eastern end on Boxley Warren, chalk scrub of
yew, hawthorn, dogwood and whitebeam is developing towards woodland.
The Escarpment contains
a wide range of woodland types which
individually may be better represented by examples elsewhere: e.g.
beechwoods at Crookhorn Wood; yew-woods at Kingley Vale; plateau
woods at Box Hill. Nevertheless the woodland complex taken as a
whole and in conjunction with the associated grassland and scrub
qualifies for grade i status (see also L.io).

The site is on a steep
slope at 15-140 m over rocks of the Bowland
Series, which consist of a mixture of sandstone, mudstone and
calcareous shales. The soils vary from shallow acid podsols through
brown earth types on ridges to deep sandy mulls (pH 6.5) on the
slopes of the two shaly ravines. The canopy, which appears to be
uneven-aged, is dominated by sessile oak and ash; also present are
birch, Scots pine, and gean. Wych elm and small-leaved lime are
locally abundant. The shrub layer is only developed to any extent in
the ravines and includes hazel, hawthorn, elder, rowan and guelder
rose.
On the podsolic areas the
ground flora is a Deschampsia flexuosa-
Vactinium myrtillus dominated community, whilst Mercurialis perennis
takes over on the neutral mull soils. Also present in the field
layer are Endymion non-scriptus, Lonicera periclymenum, Primula

Grade i
The most important feature
of this site is the massive central
exposure of Carboniferous Limestone pavement, which is probably the
finest example in Britain of this extremely local habitat. The
vegetation of the pavement is described under lowland grasslands
(L.I34). There is a patchy distribution on the pavement of a tall
scrub with yew, hazel, juniper and young ash, and this has
associated shrubs such as purging buckthorn, spindle, dogwood,
privet, holly, small-leaved lime and Sorbus lancastriensis. This
type of scrub grades into taller woodland on more broken and
dissected pavement around the edges of the central mass, and there
is a general increase in stature of species such as ash and hazel on
deeper soils, where pedunculate oak also appears. This rather low
and open type of woodland has a rich limestone flora, with species
such as Convallaria majalis, Epipactis atrorubens, Atropa
belladonna, Hypericum montanum, Rubus saxatilis, Carex digitata,
Polygonatum odoratum and Melica nutans.
The pavement woodland passes
into a broad peripheral zone of taller
forest, though this varies in height and structure according to past
differences in management. In general, there is a dense coppice of
hazel, with standards of pedunculate oak, ash and sycamore. There
are also thickets of silver birch, and hornbeam and beech occur
locally, though both were probably introduced. The drift-derived
soils in this part of the wood vary from basic to moderately acidic,
and there is a lesser abundance of markedly calci-colous species
than in the limestone woodland. Bramble is widespread throughout the
coppice, and the field layer characteristically has Mercurialis
perennis, Endymion non-scriptus, Brachypodium sylvaticum, Primula
vulgaris, Sani-cula europaea, Circaea lutetiana and Viola riviniana.

35 ha
Grade i
This has been chosen as
an example of a northern mixed deciduous
woodland, and lies mainly on the east side of a deep glen draining
the northern side of the Bowland Fells. It lies on Carboniferous
shales and sandstones which give a range of soils from highly acidic
to strongly basic, and it is ungrazed. The most acidic brown earths
have typical sessile oakwood with Vaccinium myrtillus, Luzula
sylvatica and heath mosses. This grades into a mixed oak-birch wood
on slightly less acidic soils, and the field layer here is of Holcus
mollis and Endymion non-scriptus, with Stettaria holostea, Athyrium
filix-femina and Pteridium aquilinum. On wetter ground this type
changes to alder-birch wood, with Deschampsia cespitosa, Carex
remota, C. laevigata, C. sylvatica, Dryopteris spinulosa, D.
austriaca and Ranunculus repens. On the most basic soils there is a
mixed ash-oak-wych elm-hazel wood, with grass-herb communities of
the Brachypodium sylvaticum-Deschampsia cespitosa and Mer-
curialis perennis-Allium
ursinum type. Species of particular
interest include Stellaria nemorum, Carex pendula, Festuca
altissima, Phyllitis scolopendrium, Polystichum setiferum and P.
lobatum.
Although this is a woodland
developed on the steep sides of a glen,
it extends over more level ground on top of the east bank, and
covers a larger area than many gorge woods.

This exceptionally diverse
woodland lies almost at sea-level (0-20
m) on the east side of the Leven Estuary at the head of Morecambe
Bay. It merges to the east into the northern end of an estuarine
raised mire complex (the Holker Mosses) and to the west and north
into salt marsh flanking the Leven Estuary. The wood itself covers
two ridges of contrasting
geology separated by a
shallow valley which contains a valley mire
and small tarn.
The east ridge is of Carboniferous
Limestone and carries an ash-oak
wood with some small-leaved lime, gean and birch. The oak is mainly
pedunculate but sessile and intermediate forms occur. Characteristic
limestone shrubs include purging buckthorn, spindle, blackthorn and
guelder rose, and there are also hazel, holly and hawthorn. The
field layer of this ash-oak wood is markedly calcicolous, with a
general predominance of Brachypodium sylvaticum and Mercurialis
perennis, local abundance of Convallaria majalis, and a wide variety
of species. The more local herbs include Allium scorodoprasum,
Aquilegia vulgaris, Anacamptis pyramidalis, Brachypodium pinnatum,
Campanula latifolia, Carex digitata, Hypericum montanum, Inula
conyza, Lathraea squamaria, Lithospermum officinale, Neottia nidus-
avis, Ophrys insectifera, Ornithogalum umbellatum, Rubus saxatilis
and Sesleria albicans.
The west ridge is composed
of greywackes of the Ban-nisdale Slate
Series, with small areas of slate, and carries a contrasting sessile
oakwood with birch and some rowan and hazel. The field layer is
acidophilous, with dominance of Deschampsia flexuosa and Pteridium
aquilinum, or Molinia caerulea where there is an overlying peaty
alluvium.
The valley mire between
the ridges has a fairly eutrophic fen
vegetation, with Phragmites communis, Carex paniculata, C.
vesicaria, C. diandra, C. disticha, C. pseudocyperus, Juncus
subnodulosus, Calamagrostris canescens, Thalictrum fiavum,
Thelypteris palustris, Lycopus europaeus, Lythrum salicaria and
Lysimachia vulgaris. The tarn has species such as Baldellia
ranunculoides and Alisma plantago- aquatica. There is a scattered
growth of birch and alder on this wet ground. The greatest rarity of
Roudsea Wood, Carex flava (here in its only known British station),
occurs on the transition from dry limestone soils to peat, and
flourishes along the rides in this habitat.
Where the limestone ridge
passes into the raised mire system, there
is a change to birchwood over peat, with rowan and some Scots pine.
Where the canopy is open, there is dominance of bracken, but with
deeper shade this is replaced by bilberry. Alder buckthorn is a
conspicuous shrub in this transitional woodland. There is then a
change to the open mire surface, somewhat dried by cutting, draining
and burning, but still with characteristic plants such as Andromeda
polifolia, Narthecium ossifragum and Drosera rotundifolia. The
larger area of the adjoining Deer Dike and Stribers Mosses are a
grade i peatland site (P.4y), and form with Roudsea Wood a single
composite grade i site.
On the western and northern
side there is a transition from oakwood
through alderwood to estuarine salt marsh, a sequence seen in few
other places, though the oak is on higher rocky bluffs and is not a
serai development from salt marsh. The brackish transition zone is
marked by the presence of such plants as Carex distans, C. extensa,
C. otrubae, Samolus valerandi, Oenanthe lachenalii, Centaurium
littorale and Scirpus maritimus.
This site contains an unusual
range of habitats, and the flora of
the Roudsea Wood site contains at least 340 vascular 90 Woodlands
species. The woodland and
the adjoining mosses are also very rich in
Lepidoptera, and this is a station for the rare white-marked moth
Cerastis leucographa.

W.I27. LEIGHFIELD
FOREST, LEICESTERSHIRE
SK 7502. 170 ha
Grade 2
Leighfield Forest was recommended
for special status in Cmd 7122
(Ministry of Town and Country Planning, 1947) and relics of this
ancient woodland still remain. The site is composed of four woods
(Loddington Reddish, Tugby, Tilton and Skeffington woods) grouped in
the Eye Brook valley which runs through Jurassic ironstone and
clays. Deposits of boulder clays and gravels have resulted in rich
loamy and calcareous clay soils. The tree canopy is mainly standards
of oak plus wych elm, together with ash, often coppiced. The
understorey of hazel and field maple is often dense and there is a
mixed association of shrubs including dogwood, Midland hawthorn,
privet, sallow, elder and buckthorn.
Filipendula ulmaria and
Juncus spp. occur extensively in the rides
with Rubus fruticosus and Pteridium aquilinum locally abundant.
Beneath the coppice, Mercurialis perennis is dominant with clumps of
Deschampsia cespitosa and Dryopteris filix-mas. Myosotis sylvatica
is abundant and the presence of Vicia sylvatica, Campanula
trachelium and Dipsacus pilosus is of interest.
The more important Lepidoptera
of the Eye Brook valley include
Cymatophorina diluta, Nola confusalis, Ladoga Camilla, Nymphalis
polychloros, Quercusia quercus and Ochlodes venata which are rare or
not present elsewhere. The list of Coleoptera from these woods
includes a number of rare or localised species of which the
following are the most noteworthy: Platyrrhinus resinosus, Anthribus
fasciatus, Metoecusparadoxus, Lissodema quadripustulata, Hypophloeus
bicolor, Agapanthis villosoviridescens, Tetropium gabrieli, Pediacus
dermestoides and Nemosoma ekmgatum. The woods of this area are among
the most northerly known British localities for many species of
Coleoptera, including some of those listed above.
The earliest record of
these sites is 1235 and it is believed that
they have indeed been wooded since that time. The vegetation as a
whole is typical of that found on heavy boulder clay but this is
already represented in the grade I series by Monks Wood (W-42) and
Castor Hanglands (W-44), so Leighfield Forest is given grade 2
status.

W-45(i). BARDNEY
FOREST (LINCOLNSHIRE LIMEWOODS), LINCOLNSHIRE
Grade I
(a) Hatton Wood TF 1674.
35 ha
The eastern (non-conifer)
part is high forest of lime and oak of
some 80-90 years' growth over a sparse shrub layer of hazel. The
ground flora includes Convallaria majalis, Luzula sylvatica and
Campanula latifolia. The eastern end is secondary oak-ash woodland,
as is the northern strip beside the stream. Adjacent to the high
forest is an overgrown pond with Salix fragilis and S. viminalis. A
small part of the main wood is well-developed oak standards over
hazel coppice.
Hatton Wood lies on heavy
clay, acid or neutral at the surface, with
variable quantities of sandy drift overlying this in patches.
Floristically, the wood is limited, but is selected as the limewood
which most closely corresponds with a high forest structure.
(b) Newball and Hardy Gang
Woods TF 0876, TF 0974. 88 ha
Newball and Hardy Gang
Woods were almost continuous until the
nineteenth century when the intervening Cold-stead Wood was cleared.
They both lie on clay with a covering of sand which varies from over
50 cm in depth to negligible. On the clay soils, most of which are
gleyed, there are extensive tracts of lime coppice, whilst on the
low- lying clays aspen, hazel and ash are abundant with no lime.
On the deep sands, birch scrub with bracken and Holcus mollis is
prevalent. Marginal to this, sessile oak and hazel dominate with the
birches. The soils of both woods are almost entirely strongly to
mildly acid, with small areas of heavy neutral soils notable for the
increase in abundance of calci-coles such as field maple and dog's
mercury. In Newball Wood there is a small patch of plateau alder
coppice on locally waterlogged sand, which constitutes an important
ecological line with the large fen-edge coppices near Woodhall Spa
and Tumby. Both woods appear to have been simple coppice with only
few oak standards, but the northern part of Newball has a number of
oak standards. In Hardy Gang there is a small area where pedunculate
oak is one of the main coppice species, with some large, ancient
stools. Records to date indicate that Newball Wood alone is
floristically the richest of the Lincolnshire limewoods, with Hardy
Gang only slightly less rich: their flora includes many of the local
woodland species. Furthermore, Newball is, on present evidence, the
richest limewood entomo-logically.
Both sites have been partly
felled and replanted with
conifers. The southern
part of Newball was the scene of a Forestry
Commission trial, and the small control plots of untouched coppice
are important remnants which indicate the nature of the coppice over
much of the land now under new plantations.
(c) Stain-field and Scotgrove
Woods TF 1273, TF I37°- 87 ha
Unlike other woodlands
in central Lincolnshire, the Stain-field
Woods occupy a shallow basin situation. The soils vary from sand
with a high water table to strongly gleyed and well-drained acid and
neutral clays. Much of the woodland is lime coppice but with a
variety of other species, notably the birches. The wide range of
ground flora communities extends to the Lonicera periclymenum,
Convallaria majalis, Rubus- Section Suberecti community on strongly
acidic, organic sand, and to Sphagnum where similar soils have the
water table permanently at or near the surface.
Within a short distance
of Stainfield Woods, but separated from it
by arable farmland, is Scotgrove Wood. This is a good example of
lime- oak coppice derived from oak over lime coppice-with-standards,
developed mainly on acid, poorly drained clays, which have an
appreciable sand fraction in surface horizons at the southern end.
The marginal diversity characteristic of coppice woods shows well at
Scotgrove, where wild service and wych elm are confined to the
woodland edge. A drainage line runs through the southern area, along
which mixed coppice of ash, maple, hazel occurs over a fen-like
ground flora including Carex acutiformis. The northern boundary is
marked by a massive dyke and bank, on which calcareous clay subsoil
is exposed, and a rich flora has developed, including calcareous
grassland, and mixed scrub and coppice.
Both woods have been partly
felled and replanted with conifers. The
most important areas for conservation are the western part of
Scotgrove and the sections of Stainfield known as Great South and
Demerose Woods. Of these the Stainfield part is more important for
its unusual edaphic conditions.
(d) Potterhanworth Wood ;
TF 0767. 35 ha
The western half has been
converted to conifers, but the eastern
half remains as coppice derived from coppice-with-standards, on a
site which is known to have been continuously wooded. The relatively
strong relief gives rise to both receiving sites and freely drained
slopes. Much of the wood lies on clay but a substantial tract lies
on sandy loam above the clay. Most soils are neutral, but the
textural and drainage variety is sufficient to enable a wide range
of ground flora communities to develop. Most of the coppice consists
of almost pure small-leaved lime but, towards the south, lime is
rare, ash, oak and birch being the most abundant. The particular
features of Potterhanworth are repeated to some extent in other
Lincolnshire limewoods, but in the presence of Frangula alnus,
Prunus avium and Campanula trachelium it has affinities with woods
further south and west. The Roman-built Car Dyke runs along its
eastern margin.
W-45(ii). BARDNEY
FOREST (LINCOLNSHIRE LIME-WOODS), LINCOLNSHIRE
Grade 2
(a) Great West-Cocklode-Spring
Woods TF 1076. 37 ha
Four contiguous woods occupy
a relatively low-lying area along
parish boundaries. Of these Little West, and substantial parts of
Cocklode and Great West, have been felled and replanted with
conifers. The remaining areas under lime woodland include one of the
best high forest stands (Great West); a herb-rich coppice (Spring)
in which Carex strigosa, Ophioglossum vulgatum and Myosotis
sylvatica occur; and an area of uniform coppice of high potential
research value (Cocklode), all on mainly neutral clay and sandy clay
soils. In Cocklode, outlying parts of the earthworks of Bullington
Priory extend into the wood and offer an opportunity to study the
development of the characteristic woodland. Recently some two-thirds
of Spring Wood was cleared for arable cultivation.
(b) Stainton-Fulnetby Woods'
TF 0778. 68 ha
Stainton, Fulnetby and
Rand Woods form contiguous stands, of which
Rand has been completely felled and replanted with conifers.
Stainton is typical high forest lime woodland in which lime is a
minority element through part of the wood. Fulnetby is the best
remaining stand of coppice-with-standards oak over lime, with
spindle locally common, but is floristically impoverished in
comparison with most other woods.
(c) Wickenby Wood TF 0882.
45 ha
Uniformly wet throughout,
this coppice has a variety of woodland
types, being partly dominated by lime, with areas of ash, maple and
hazel and local dominance of willow. Wickenby is one of the richer
woods floristically, and is markedly the most alkaline of all the
Lincolnshire lime-woods. As such there is a case for including it as
a grade I site, but most of its features can be found elsewhere in
grade i sites, even if they are less well-developed than at Wickenby.

W.s8. KESTEVEN WOODS, LINCOLNSHIRE
Grade 2
The concentration of woods
in southern Lincolnshire and Rutland is
mainly dominated by pedunculate oak, ash and hazel over
predominantly calcareous clay soils. Most if not all have been
managed as coppice- with-standards. They mostly have a rich
assemblage of subordinate native tree and shrub species, including
wild service, field maple, midland hawthorn, wayfaring tree, gean
and aspen. The ground flora is usually dominated by mixtures
including dog's mercury, Sanicula europaea, primrose, bluebell, wood
anemone and bramble, but a number of local species are found,
including Milium effusum, Sedum telephium, Epi-pactis helleborine,
Carex strigosa and Dipsacus pilosus.
As a group they have both
similarities with and fundamental
differences from the Bardney Forest woods (W-45). They had a similar
development and their range of coppice types overlap to some extent,
but the Kesteven Woods have mainly calcareous soils and,
correspondingly, limewood is relatively rare and calcicolous species
such as Campanula trachelium are more abundant. Here, as in Bardney,
the full range of variation is represented in a number of small
woods, the differences between which yield information on the
effects of management. The Kesteven Woods are placed in grade 2, but
they are not regarded as a substitute as a group for the Bardney
Forest woods.
The Kesteven Woods have
not been surveyed in detail and the
selection within them is extremely tentative. Further survey may
reveal other sites which merit grade 2 status, either in addition to
those selected, or more likely as replacements for them. In
particular, Tortoiseshell Wood is a good example of calcareous
coppice with an excellent structure, with large numbers of well-
grown standard oaks and some magnificent standard wild service trees.
(a) Dole Wood
TF 0916.
5 ha
This is a small, coppice-with-standards
wood of oak, hazel and ash,
with abundant midland hawthorn, and small areas of lime and elm. The
ground flora ranges to mildly acid communities with Holcus mollis,
Teucrium scorodonia and Lonicera periclymenum.
(b) Dunsby Wood
TF 0826.
60 ha
Formerly this was coppice-with-standards,
but most of the oak
standards have been removed and the coppice has been allowed to grow
up. The canopy is now mainly ash and field maple, with birch, aspen,
gean and patches of invasive English elm. In the shrub layer, hazel,
midland hawthorn, crab apple, and wild service are locally abundant.
The ground flora includes Dipsacus pilosus and Carex strigosa.
(c) Kirton Wood
TF 9832.
30 ha
Kirton Wood still possesses
its coppice-with-standards structure,
but the coppice ash has now become rather overgrown. Small-leaved
lime is abundant in parts. The ground flora is predominantly
calcicole, with abundant Filipendula ulmaria, Geum rivale and
Valeriana officinalis.
(d) Sapperton-Pickworth
Woods
TF 0334.
25 ha
Although formerly one wood,
this has now been divided by partial
clearing into three separate stands. These retain a good quality oak-
ash coppice-with-standards structure with local blackthorn
thickets. Parts of the wood are invaded by English elm. The ground
flora includes Campanula trachelium.

MARSHES, NORFOLK
TG 3316.
245 ha
Grade i
Alder occurs extensively
sometimes in association with ash,
pedunculate oak and birch, and the shrubs include buckthorn, alder
buckthorn, guelder rose and grey sallow.
Species of Ribes (R. nigrum,
R. silvestre and R. wva-crispa) occur
and are very characteristic of this woodland type as are the
climbers Calystegia sepium, Humulus lupulus and Solanum dulcamara.
The field layer contains Carex panicu-lata, Iris pseudacorus, Urtica
dioica and Thelypteris palustris. The alder woodland here is
probably the best example of its type in Britain, showing as it does
a complete range of successional stages from open marsh, together
with floristic richness. The site has also been given grade i*
status as a peatland (P.y).

W-5O. FELBRIGG WOODS, NORFOLK
TG 1940.
155 ha
Grade 2
Felbrigg Great Wood and
Felbrigg Park lie on the gravels of the
Cromer End Moraine. The Great Wood is ancient beech forest, closed
over large areas, but opened locally to admit birch regeneration.
Mixed with beech are some oak and holly and these, together with the
pollarded beech, add to the similarities between this site and some
of the Wealden and New Forest woods. The ground flora is largely
composed of bryophytes, with Dicranum scoparium, Plagiothecium
undulatum, Polytrichum formosum and Leucobryum glaucum abundant.
There is a rich epiphytic flora, including Iso-thecium myosuroides
and Parmelia perlata, both rare in Norfolk.
Felbrigg Park is ancient,
open oak woodland with some old sweet
chestnut and sycamore. The pasture remains un-ploughed. The
epiphytic lichen flora is one of the richest in Norfolk, with many
old-forest species.
The site is selected primarily
as a representative of beech-woods at
the limit of their supposed native range. It is also worthy of
selection as an overmature woodland with an epiflora rich by the
standards of eastern England.

W-47. FOXLEY WOOD,
NORFOLK
TG 0524. 65
ha
Grade 2
Three broad woodland types
occur in Foxley Wood. The most
widespread, on wet clay soils, is mixed deciduous in which
pedunculate oak and hazel are the most abundant, but ash, field
maple and birch are common and a number of other tree and shrub
species are present. The ground flora here is Filipendula ulmaria-
Geum rivale grading to Mercurialis perennis- Endymion non-scriptus
and Convallaria majalis on the drier areas. The 'sacred ground' near
the wood's centre is sandy, with oak high forest over a
discontinuous holly understorey and a ground flora dominated by
bracken and Holms lanatus. Thirdly, a flushed tract is occupied by
alder coppice, while alder also occurs as a constituent of coppice
on the lighter soils. Floristically, Foxley is one of the richest
woods in East Anglia: though no rare species are recorded, many are
very local, notably Myosotis sylvatica, Sedum telephium, Sorbus
torminalis, Primus padus and Carex strigosa.
Though Foxley has been
partly replanted with conifers, and the
remainder has been cleared of all worthwhile timber, the site is
nevertheless important. As an ancient coppice site, it is unusual in
possessing alder, and in some respects grades into fen woodland
(Carex lepidocarpa and Prunuspadus are present). Furthermore, this
ranges through to dry, acidophilous woodland. It is almost as
important as Swanton Novers, and in many respects is similar and is
graded as an alternative site.

W-49- SEXTON
WOOD, NORFOLK
TM 2991. 40
ha
Grade 2
Sexton Wood lies mostly
on neutral clay soils and comprises an
almost pure stand of hornbeam coppice with oak standards. Towards
the southern end the soil is almost calcareous, and here maple is
relatively abundant. Centrally there is a small, wet basin occupied
by ash and willow and a poor-fen flora. At the north end where the
soils are appreciably more sandy there is much more birch, and the
oak is dense enough to form high forest above hornbeam shrub layer.
Sexton Wood is selected
as a representative of hornbeam coppice near
its geographical limit which is still cut sporadically. Its value
for conservation is unfortunately much diminished by the state of
the rides, which are all concrete tracks. Brooke Wood, Norfolk, was
an excellent example, but it has been almost completely replanted
with conifers, and Sexton Wood may be the best remaining example.
However, the woods of south-east Norfolk are insufficiently known
and other, better examples may b

W-39- SWANTON
NOVERS WOODS, NORFOLK
TG 0131.
65 ha
Grade i*
This wood straddles a geological
boundary between glacial sands and
gravels to the north and calcareous boulder clay at the southern
end. Correlated with this is the boundary between two contrasting
woodland types. On the acid sands and gravels, coppice-with-
standards with both species of oak in intimate mixture forms a
closed canopy over Pteri-dium aquilinum, Lonicera periclymenum,
Convallaria majalis and Calluna vulgaris with Teucrium scorodonia
along the rides. Mixed deciduous woodland grows over the mildly acid
and neutral boulder clay: this is coppice-with-standards with both
oak species as standards over mixed coppice of small-leaved lime,
ash, maple and willow. The ground flora here comprises Filipendula
ulmaria, Geum rivale, Ranunculus repens on the damp areas, and Mer-
curialis perennts, Endymion non-scriptus on the drier transition to
the sands. In a very wet site on the western margin a third woodland
type with oak, alder and bird-cherry exists. Floristically the site
is exceptionally rich with at least 25 native tree and shrub
species, and a number of rare and local herbs, notably Maianthemum
bifolium in what is almost certainly a native location. Many
bryophytes and epiphytic lichens have been recorded, but most of the
species are common and widespread.
Swanton Novers is undoubtedly
an important site, containing three
woodland types, each of which on its own would have been enough to
justify selection. Furthermore, the mixed coppice is still actively
worked, but a small block has been felled and replanted with
conifers. It is almost certainly a primary woodland site and as such
constitutes an important contrast with the more widespread type of
oak-ash-maple-hazel primary woodl

W-48. WAYLAND
WOOD, NORFOLK
TL 9399.
35 ha
Grade 2
Lying on wet, calcareous
boulder clay, this is a coppice-with-
standards woodland. Pedunculate oak is the main standard which with
a few ash and birch forms a fairly open canopy. The coppice layer
contains a limited amount of ash and field maple, but is mainly a
hazel-bird-cherry mixture with dogwood, willow and groups of holly.
At a point on the margin, elm has encroached into the wood. The soil
is wet throughout, and the ground flora is mainly of the Filipendula
ulmaria type with no Mercurialis perennis. Said to be rich
floristically, this is the only site for Gagea lutea in Norfolk.
This is a good example
of a coppice-with-standards woodland still
managed as such. It is selected for this and the unusual combination
of coppice species otherwise unknown in lowland England.

W.I28. PIPEWELL
WOODS, NORTHAMPTONSHIRE
SP 8286.
80 ha
Grade 2
Monks Arbour and Pipewell
Woods lie on deep, calcareous clay soils
at the south-western extremity of Rockingham Forest and have a
coppice- with-standards structure. Pedunculate oak is the main
standard species, with ash, birch and a few planted beech. The
coppice layer is dominated by hazel, with ash, dogwood and field
maple locally abundant in Monks Arbour Wood. The field layer ranges
from Mercurialis perennis-Galeobdolon luteum on the drier soils, to
Filipendula ulmaria-Ranunculus repens in waterlogged patches, and
Pteridium aquilinum-Rubus fruticosus-Hokus lanatus on the more
acidic patches. The ground flora includes such local species as Iris
foetidissima and Campanula latifolia. At the southern end of
Pipewell Wood, English elm has invaded from the hedge to form a
nearly pure community.
This is one of the Ancient
Forest coppices. It is typical of such
woods and has the advantage that it is not damaged by ironstone
working or replanting with conifers, and indeed the coppicing
continues actively. Other woods in Rockingham Forest, however, were
once known to be richer faunally.

W.I29- WHITTLEWOOD
FOREST, NORTHAMPTONSHIRE
SP 7342. noha
Grade 2
Three relics of this ancient
woodland, in the south of the county,
still remain. They once formed a link in the chain of woodlands
which stretched across the clay belt from Oxfordshire to Huntingdon
and Peterborough. Lying on calcareous clays and boulder clays they
are typical examples of the woodlands on these soil types.
Buckingham Thick Copse is the largest area; it contains fairly
uniform oak-ash high forest. Understorey and shrub species are
confined to the rides and edges; these include field maple, dogwood,
Midland hawthorn and hazel. Sweet chestnut is also present. The
ground flora is dominated by Rubus fruticosus, Chamaenerion
angustifolium with Deschampsia cespitosa and Brachypodium
sylvaticum. Patches of Lusula multiflora and Carex pendula indicate
waterlogging. Say's and Smalladine Copses are similar but ash or
English elm outnumber the oak in parts. The shrub layer is better
developed here and is dominated by hazel. Cornus sanguined, Euonymus
euro-paeus and Viburnum opulus are common in the hedgerows.
Lichens that are absent
or rare elsewhere in the county are found
here; these include Lecanora confusa, Usnea certatina, Opegrapha
varia and Pertusaria lutescens.
East and West Ashall's
Copses consist of ash scrub and
mature ash woodland and
oak is only locally dominant. English elm
occurs on the edge and hazel, hawthorn, field maple and Midland
hawthorn are present in the understorey and shrub layers. The ground
flora here is dominated by bramble interspersed with areas of
Deschampsia cespitosa, Oxalis acetosella and Glechoma heeleracea.
Other plants include Sanicula europaea, Epipactis helleborine, E.
purpurata and Dactylorchis fuchsii.

PARK AND GRASSLEES WOOD, NORTHUMBERLAND
NY 9496.
175 ha
Grade 2
The site lies in a small
valley fed by branches of the Grass-lees
Burn. The woodland, mainly on shallow peat of gleyed alluvial soils,
occupies the bottom and lower slopes of the valley and extends up
the tributary glens. Alderwood occupies the area near the stream and
this is surrounded by oak-hazel or birchwood on the higher, better-
drained slopes. The alderwood is pure and contains a good spread of
age classes from old senescent trees to young regeneration stages.
The oak-hazel woodland contains many old hazel shrubs carrying good
epiphyte communities. The ground flora under the alder is dominated
by Juncus spp. including J. effusus, jf. articulatus and Agrostis
stolonifera; also present are Mentha aquatica, Carex pendula, C.
remota, C.paniculata and Sphagnum spp. A glade containing Myrica
gale, Eriophorum latifolium, Parnassia palustris, Angelica
sylvestris and Viola palustris is present. The bryophyte flora is
rich and
alkaline runnels contain species such as Fissidens
osmundoides, Bryum pallens, Cratoneuron commutatum, Ctenidium
molluscum and Mnium punctatum. The epiphyte flora of lichens and
bryophytes is varied, because of the high humidity, and the species
recorded include Antitrichia curtipendula, Pyrenola sp. and Arihonia
spp. The area is also of ornithological interest. See also U.z8..

ancient parkland woods and partly a ravine woodland which, like
Hareshaw Linn, is pedunculate oakwood over acid soils, grading to
wych elm woodland on calcareous soils. The parkland area of ancient

Parmeliop- sis hyperopta and Haematomma elatinum.
Hesleyside has marginally

WOODS, NORTHUMBERLAND
NT 9201, NT 9301, NT 9401.
30 ha
Grade 2
This site has four separate
units, three being composed principally
of sessile oak woodland and the fourth a mixture of habitats
including woodland and moorland in which juniper scrub is a
significant feature.
The small sessile oakwoods
occupy mainly the south-facing slope of a
glen draining from the Carboniferous gritstone moorlands of the
Harbottle Moors, south of the main Cheviot range. They are examples
of this woodland type in a much drier climate than that of Lakeland
or north Wales. They adjoin young conifer plantations and are now
less grazed by sheep than formerly. In Holystone Burn there is open
growth of medium-sized spreading oaks, some of which are large for a
hill wood. North Wood consists in the main of twisted, many stemmed
trees suggesting former coppicing. Underscrub is absent, and field
communities are of the type found in Lakeland sessile oakwoods on
acidic soils. There is an abundance of bracken in open places, and
the field dominants include Deschampsia flexuosa, Vaccinium
myrtillus, with much Galium saxatile, Potentilla erecta and
Melampyrum pratense. Heath mosses cover part of the ground but
Atlantic bryophytes are very few. The northern
herb Trientalis europaea
is abundant. The steep opposite bank has
birchwood with tall heather and a luxuriant carpet of heath mosses
and Sphagnum which is the habitat of Lister a cor data.

Grade 2
Monk Wood and its surroundings
are part of the ancient Whitfield
Park, lying in the sheltered valley of the River West Alien. The
parkland is open, old woodland of ash, wych elm and sycamore, with
the richest epiphytic lichen flora known in north-east England. The
main block of woodland, estimated at 250-300 years old, is an almost
pure stand of sessile oak with only occasional beech, birch and
rowan. The shrub layer is not well developed except towards the foot
of the slope where rhododendron is abundant and hazel and hawthorn
are locally common.
Where not shaded out by
rhododendron, Luzula sylvatica forms a
continuous carpet. While the variety of field layer species is not
great, the presence of Vicia sylvatica is noteworthy. There is a
luxuriant epiphytic lichen flora in which Lobaria pulmonaria is
locally abundant. Although the wood has not been thoroughly examined
it is already known to be an important site for epiphytic species.

SK 6368.
525 ha
Grade 2
The Birklands and, to a
lesser extent, the Bilhaugh are fine
remnants of Sherwood Forest.They lie on deep, freely drained acidic
soils developed from Bunter Sandstone. The woodlands are an actively
regenerating population of both oak species in more or less equal
numbers, with a wide size range from saplings to some of the largest
oaks in the country. Between these extremes are younger, but mature
generations of the oaks. Birch (mainly Betula pendula) is abundant,
forming groves between the oaks, but the canopy is still rather
open, enabling a dense bracken field layer to develop. The flora is
very poor, restricted to calcifuge species, and the epiphyte lichen
flora has been largely eliminated by pollution. The beetle fauna,
however, is very rich and contains some extremely rare species.
The oak population here
is exceptional but public pressure and
atmospheric pollution have damaged the area, hence it is accorded
grade 2 status.
Immediately to the north
lies Budby South Forest Heath (170 ha) on
soils derived from the Bunter Sandstone at an altitude of about 60
m. The heathland area is dry heath dominated by heather and
Deschampsia flexuosa. Much of it (c. 50%) is covered by scattered
birch or birch scrub. There is some gorse scrub but this habitat is
by no means abundant on the site. Bracken is only locally abundant.
The heath is at present
used as a military training area but there
is little apparent physical damage and the site has not been
extensively burnt in recent years. Its inclusion within the grade 2
site adds interest.

W.29- ASTON ROWANT
WOODS,
BUCKINGHAMSHIRE/OXFORDSHIRE
su 7598.
275 ha
Grade 2
Grove Wood is a scarp woodland
dominated by tall vigorous beech. It
appears to be even aged (123-169 years), and below gaps in the
canopy there is a field layer of dog's mercury. Ash, sycamore and
some beech regeneration occurs. Small groups of ash and one of
common elm are present, Salix capraea is abundant in some wet sites
and whitebeam is occasional in the canopy. Mature sycamore is absent
but regeneration of this species is profuse in places. The shrub
layer is not prominent and locally is lacking altogether. It
consists of characteristic chalkland species such as elder, broom,
buckthorn, hazel, box, field maple and whitebeam.
Upper Grove Wood lies on
the plateau and, though pedunculate oak is
the commonest species, the canopy contains frequent ash and beech
with coppiced small-leaved lime, gean, hornbeam and hawthorn.
Saplings of all these species, except oak, are present: Paris
quadrifolia grows here.
Aston Wood forms a curving
rectangular block facing north-west, to
the south of and above the A4O trunk road. It is contiguous with the
present NNR. Beech (90-150 years old) dominates the western two-
thirds, but a number of other species share the canopy. Oak,
whitebeam, sycamore and hornbeam are rare but ash and gean are
locally abundant, filling in gaps left by selective felling. In
addition to ash and gean, beech, sycamore and elder saplings are
present, and some of the young beech is now 20-25 years old. Holly,
hawthorn and elder form a sparse understorey
with rowan and hazel coppice
stools in a depression at the eastern
end. The eastern one-third of Aston Wood is dominated by ash, though
beech occurs frequently and oak is abundant. Mixed with these are a
few sycamore, gean, Norway spruce, elder, holly and large coppiced
rowans. The boundary between the two parts of Aston Wood is marked
by three large lime stools and a number of young trees.
On a narrow strip of sloping
ground between the A4O and the old sunk
way down the escarpment, lies a woodland of great ecological
diversity. Beech and numerous pole ash form the canopy with some
sycamore, and there is a thicket of blackthorn, a group of poorly
grown larch, a group of common elm and poplar. There is some sapling
horse chestnut, whitebeam and a stand of large field maple and
shrubs include dogwood, wayfaring tree, hawthorn and elder.
Kingston Wood, one the
largest woods in the area, extends down the
scarp slope from the plateau. Beech dominates the plateau woodland
but pedunculate oak is frequent and ash occasional. Regeneration of
beech, ash, bird cherry and willow is taking place in the gaps.
Sycamore invasion is at present being discouraged. In contrast, much
of the scarp woodland is pure beech, forming large areas of unbroken
canopy, therefore excluding both the shrub layer and regeneration.
Crowell Hill Wood is virtually a pure beech-wood and on the whole
not of outstanding interest though it contains a number of chalkland
herbs, notably Ophrys insectifera and Epipactis purpurata.
Crowell Wood is a large
block of woodland, most of which is situated
on a north-east-facing dip slope. Beech is dominant throughout but
occasional ash, oak and cherry share the canopy. Drastic thinning
occurred during the First World War and probably resulted in the
dense growth of bramble which covers the ground and may have
prevented immediate regeneration.
High Wood is another dip
slope woodland dominated by beech but,
unlike Crowell, bramble is rare in the ground flora and the canopy
is very dense. Ash is occasional and oak occurs on the upper areas.
Elder forms a sparse understorey.

W.25- WATERPERRY WOOD,
OXFORDSHIRE
SP 6009, SP 6008.
135 ha
Grade i
Waterperry Wood is part
of Bernwood Forest where extensive insect
records go back for 100 years or more. Bernwood Forest is famous for
its Lepidoptera, which include rarities such as the purple emperor
and black hairstreak butterflies. Waterperry is a deciduous high
forest lying on gently sloping land on an outcrop of Oxford Clay,
and is dominated by pedunculate oak with ash, elm, aspen and birch.
It is similar floristically to other clay woodlands such as Monks
Wood, but it is unlikely that Monks Wood can duplicate its
entomological value. Much of it has been planted with. conifers
although a final crop of oak is planned.

W.24- WYCHWOOD
FOREST, OXFORDSHIRE
SP 3316.
261 ha
Grade i
This large block of woodland
was formerly a Royal Forest,
disafforested as late as 1858. It is a complex area ecologically,
this complexity arising first from the variety of soil types derived
from the limestone, clays, marls, sands and siliceous drifts on
which it lies, and also from differences in management. Much, if not
all, of the woods were managed as coppice-with-standards but this
has now largely disappeared and the old coppice boundaries have been
obscured by more recent developments. Parts of the woodland are now
oak-wood with a proportion of ash, but large areas are dominated by
hawthorn (both species and hybrids). Many other types of scrub
occur, including blackthorn, willow, field maple and elder, the
existence of which appears to be a direct result of different forms
of management. Numerous exotic species of both soft and hard woods
have been introduced in recent decades. Floristically, Wychwood is
fairly rich, the variety of ground flora communities reflecting not
only the variety of soils and tree cover, but also the presence of
glades. It is an important site for the lichens of old woodland. The
small marl ponds within the forest are given grade 2 for their open
water interest (OW.n). (See Appendix.)

W.I3I. HABBERLEY VALLEY,
SHROPSHIRE
sj 4104.
30 ha
Grade 2
This narrow, steep-sided
valley cuts through base-rich Ordovician
shales at its lower end and acidic pre-Cambrian conglomerates, which
give rise to two contrasting soil types, and strong associated
differences in the vegetation. The base-rich lower woodland is
dominated by wych elm, large-leaved lime, ash and yew with some
sessile oak: here the ground flora is a moderately rich assemblage
of mainly calcicolous species, with abundant Mercurialis perennis
and Polystichum setiferum, the rare Circaea intermedia and a range
of calcicole and calcifuge bryophytes. On the acidic rocks sessile
oak woodland grows over a ground flora of Vaccinium myrtillus,
Blechnum spicant and Leucobryum glaucum, with a number of Atlantic
bryophytes.
Several features have combined
to justify including this site. It
has good examples of two types of woodland whose distribution is
clearly determined by the nature of the under-and holly is present,
both as scrub and as a component of established woodland. These
features reflect some of the characteristics of woodland under more
oceanic conditions and indicate a somewhat different climate on the
extreme west of the Peak District.
The woodlands of the Manifold
Valley show an extremely wide range of
variation in canopy structure and ground flora.
The grasslands included
within the site are on the whole damp and
well grazed. Agrostis spp. are generally dominant, but variations
occur according to slope and aspect. Potentilla tabernaemontani,
Carex pulicaris and Parnassia palustris are noteworthy amongst the
herbs.
Rare plant species present
include Polemonium caeruleum, Daphne
mezereum, Hordelymus europaeus, Festuca altissima, and Cardamine
impatiens. Daphne laureola, uncommon in the Peak District, is also
present.
The area is also of interest
for its karst topography. During
periods of dry weather the River Manifold disappears down a series
of swallets just below Wettonmill and the water resurges from
springs at Ham Hall about 11 km downstream. Thors Cave is an
impressive rock shelter perched on the side of the valley.

W.IIQ. TICK
WOOD, SHROPSHIRE
sj 6503.
55 ha
Grade i
This is a scarp woodland,
mostly north-facing, near the site of
Telford New Town and overlooking the Severn Valley. It overlies
Silurian rocks, predominantly calcareous shales, though a band of
Wenlock Limestone occurs along the top of the ridge.
It is essentially a pedunculate
oak-lime (Tilia vulgaris, IT.
cordata, IT. platyphyllos) high forest with ash and some elm. The
site is not managed now though hazel has been coppiced in the past.
There is one area of pure cherry in all stages of development,
including some very old trees. Many other native species are present
in the canopy including field maple, silver birch, holly, crab
apple, wild service, rowan and yew, and there are shrubs such as
spindle, privet, blackthorn, dogwood and guelder rose.
The topmost part of the
site has extensive scrub woodland and here
the ground flora is extremely rich in herbs, with abundance of
Allium ursinum with Mercurialis perennis, Filipendula ulmaria, Geum
rivale and Paris quadrifolia. Orchids include Listera ovata, Orchis
mascula, Platanthera chlorantha and Epipactis helleborine. Over the
rest of the wood Oxalis acetosella, Veronica montana and Deschampsia
cespitosa are dominant but more local species such as Carex pendula,
C. strigosa, Euphorbia amygdaloides and Campanula trachelium also
occur.
Tick Wood differs both
pedologically and floristically from better
known limestone woodlands such as those of the Derbyshire Dales and
the Cotswolds. Its vegetation is typical of woods on the highly
calcareous shales of this region.

W.I2I. WYRE FOREST,
WORCESTERSHIRE, SHROPSHIRE
so 7576. 495
ha
Grade i
Wyre Forest lies astride
the county boundary, west of the Severn, on
either side of Dowles Brook, on the varied formations of the Coal
Measures, which include sandstones, marls and conglomerates. The
soils are mainly freely drained and acidic, but local calcareous
pockets occur.
Sessile oakwood, mainly
of coppice origin, is the widespread type
but in the valleys, rich mixed deciduous woodland with wild service,
ash, elm, small-leaved lime and alder have developed. The field
layer is predominantly calci-fuge with Pteridium aquilinum,
Vaccinium myrtillus, Calluna vulgaris, Erica cinerea and Melampyrum
pratense. In the valleys, however, there is a wide variety of
habitats from moderately acidic, to basic soligenous mire with
Sphagnum spp., Molinia caerulea and Eriophorum latifolium, to
communities on drier, base-rich soils with Brachypodium sylvaticum,
Mercurialis perennis and Primula vulgaris. Within the woods many
rare and local species occur, including Cephalanthera longifolia,
Aquikgia vulgaris, Carex mantana, Convattaria majalis, Melica
nutans, Geranium sylvaticum and G. sanguineum. The whole area is
rich in bryophytes and epiphytic lichens (by comparison with the
Midlands generally), especially the Seckley Wood ravine and other
valleys. Over 320 species of fungi have been recorded here.
The forest fauna is one
of the richest in the Midlands. The mammals
include fallow deer, otter, dormouse and several species of bat, as
well as the commoner woodland species. A wide variety of woodland
and water-side birds breeds and the avifauna has been extensively
studied. Amongst the reptiles the adder is common. The insects are
outstanding for variety and number, and include some nationally rare
species. The Kentish glory and alder kitten moths are two notable
examples amongst the Lepidoptera. The rare cerambycid beetle
Strangalia nigra occurs in one of its most northerly stations, and
Wyre Forest is one of the few British localities for the terrestrial
caddis fly, Enoicylapusilla. Rare spiders and sawflies are also
recorded.
These woodlands constitute
an important meeting point of a number of
woodland features. The oaks, though mainly sessile, have characters
intermediate with pedunculate, yet the plateau woods are
structurally and floristically allied to the oak coppices of Wales.
The valley woods on the other hand have the small-leaved lime and
wild service characteristic of the southern Welsh borderlands. Local
developments of hazel, ash and dogwood over dog's mercury and
primrose on clays are reminiscent of East Anglian woods.
Floristically, too, the area is intermediate, with, for example,
Melica nutans and Geranium sylvaticum on the edge of their range.
The forest as a whole is outstanding for invertebrates and forms one
of the most important wildlife environments in the Midlands. The
most important parts are Seckley
Wood, Dowles Brook and
its tributary stream valleys, and the
coppices east of Park Brook.

W.85- ASHEN
COPSE, SOMERSET
ST 7942.
35 ha
Grade 2
This is a very fine example
of coppice-with-standards woodland with
pedunculate oak over hazel on Oxford Clay. Ash is common and other
associates are field maple and alder (along the ditches). In
addition to hazel the shrub layer contains hawthorn, blackthorn,
sallows, guelder rose and Rosa spp.
The oaks are particularly
well-grown here and, as the understorey
has not been cut extensively for many years, an interestingly varied
understorey is developing.
The field layer is characteristic
of clay woodlands with species
such as Anemone nemorosa, Rubus fruticosus agg., Endymion non-
scriptus, Viola spp., Brachypodium sylvaticum, Fragaria vesca,
Galeobdolon luteum, Mercurialis perennis, Ajuga reptans, Allium
ursinum, Carex pendula and C. sylvatica and Filipendula ulmaria.
Ashen Copse has features
resembling the eastern boulder clay
coppices and is thus, like Salisbury Wood, Monmouthshire, one of the
westernmost of this type. It is adjacent to Longleat Woods and Park,
additional remnants of the former Selwood Forest. These woods which
contrast with Ashen Copse include ancient oak-beech high forest,
mature but younger high forest and old, open park woodland, which
together have a very rich epiphytic lichen flora including numerous
old forest relic species.

W.yo. AVON
GORGE (LEIGH WOODS), GLOUCESTERSHIRE, SOMERSET
ST 5675.
105 ha
Grade i
Leigh Woods are situated
on the western side of the gorge of the
River Avon at Bristol. The area covers those woodlands on the
plateau and on the gorge side.
The plateau woodland occurs
on a shallow marl and a clay soil. A
mixture of sessile and pedunculate oak is present together with ash,
wych elm and small-leaved lime. Yew is found on some of the more
stony sites. Beech has been planted in the area and occasional
specimens of hornbeam are to be found. An important consideration in
this region is the number of rare endemic whitebeams (Sorbus spp.)
present in the woodland. S. wilmottiana and S. bristoliensis are
endemic to this area whilst S. eminent, S. porrigenti-formis and S.
anglica are all local limestone species. The ground flora contains
the common species such as Mer-curialis perennis, Endymion non-
scriptus, Euphorbia amygda-loides, Fragaria vesca, Viola sp.,
Anemone nemorosa and Rubus fruticosus agg., as well as those of more
particular note such as Aquilegia vulgaris, Carex digitata, Neottia
nidus-avis, Rubia peregrina, Orobanche hederae, Lathraea squamaria
and Helkboris viridis. Ferns include Thelypteris phegopteris and
Polystichum setiferum.
The bryophytes of this
area include Dicranum montanum, D. strictum
and Nowellia curvifolia.
The scrub woodland of the
gorge side, particularly near the quarry
areas, is of particular conservation value as it contains a mixture
of the usual calcareous scrub species, rare Sorbus spp. and in the
associated grassy areas rare plants including Veronica spicata ssp.
hybrida, Hornungia petraea, Carex humilis, Potentilla
tabernaemontani, Trinia glauca and Scilla autumnalis.
There is an interesting
list of Lepidoptera recorded. The scarce
hook- tip moth was formerly found in association with the small-
leaved lime.

W.86. GREAT
BREACH AND COPLEY WOODS, SOMERSET
ST 5031.
60 ha
Grade 2
Mainly an oak-ash woodland
on wet Lower Lias clays.
The woodland is extensive
and covers some 400 ha but felling and
replanting with beech and conifers have taken place.
The woodland varies from
almost pure oakwood in some areas, through
oak-ash woodland to some stands of almost pure hornbeam and of
English elm. There is a wide range of associated trees and shrubs
which include field maple, sycamore, alder, sweet chestnut, beech
and sallows. The shrubs include traveller's joy, dogwood, hazel,
hawthorn, spindle, privet, blackthorn, elder, gorse and wayfaring
tree. There are also many spruces, larches and pines.
The field layer is characteristic
of the more base-rich clays with
Mercurialis perennis, Carex pendula and Rubus fruticosus agg.
locally abundant, and a good variety of other species.
The area forms a good example
of a western oak-ash wood on clay with
a wide range of associated species.

W.84- HOLFORD
AND HODDER'S COMBES, SOMERSET
ST 1540.
325 ha
Grade 2
The Quantock Hills consist
of Devonian sandstone and grits. At the
northern end two steep-sided combes above Holford are clothed for
much of their lengths in sessile oak woodland of coppice origin.
Other species are present in small numbers, including birch, holly,
rowan and alder. Structurally the stands vary from dense, young
coppice to mature, but short, high forest. Growing only 3 km from
the coast at elevations up to 300 m, the more exposed portions are
severely wind-pruned. The ground flora is dominated by bilberry,
bracken, heather and other calcifuges, with only local development
of base-rich conditions with primrose and Chrysosplenium
oppositifolium.
The woodlands of the two
combes are not quite contiguous, but are
linked by heathland of Calluna vulgaris, Ulex gallii and Erica
cinerea. The site extends up the combes to Bircham Wood and the
Dowsborough respectively.

W.69- HOLNICOTE AND
HORNER WATER, SOMERSET
ss 8943. 405
ha
Grade i
This area, part of an extensive
complex of woodlands owned by the
National Trust, lies mainly on Lower Old Red Sandstone which
produces relatively poor soils. The valley bottoms contain high
forest of pedunculate oak together with ash, wych elm and birch. The
shrub layer in this valley woodland contains hazel and holly with
Rosa spp. The field layer is dominated by bramble but species such
as Geranium robertianum, Glechoma hederacea, Teucrium scorodonia,
Viola spp. and Oxalis acetosella also occur.
Higher up the slopes the
pedunculate oakwood gives way to sessile
oakwood which was formerly coppiced. The associated species here are
much more acidophilous and include birch and rowan in the shrub
layer and Blechnum spicant, Luzula pilosa, Holcus mollis, bracken
and bilberry in the field layer. The acidophilous oakwood gradually
merges into moorland on its upper edge with Calluna vulgaris, Erica
cinerea and Ulex sp. The upper edge of the woodland is particularly
exposed and the wind shapes the canopy here to near ground level.
The lichen flora is very
rich both in numbers of species (no) and in
the presence of many rarities, such as Usnea articulata, which are
now confined to south-western England because of air pollution
elsewhere. This assemblage of species is very characteristic of
ancient forest areas in northwestern Europe.
This is an extensive area
of characteristic Exmoor woodland which
shows the transition from moorland to valley woodland particularly
well. It is also an important wintering area for the Exmoor red deer
which form one of the three largest concentrations of red deer in
England.

W.yi. MENDIP WOODLANDS,
SOMERSETGrade i (
a) Rodney Stoke ST 4950.
35 ha
Although five facies of
ashwood and one each of oak, lime and elm
have been recognised the intermediate types are so extensive that
the area is best considered as a varied ash-wood. These woodland
types occur over Carboniferous Limestone with some areas of
Dolomitic conglomerate. Pedunculate oak is an important associate
and field maple, wych elm, small-leaved lime and whitebeam are of
lesser importance. Other species which occur are crab apple,
blackthorn, hawthorn, buckthorn, sallows, elder and wayfaring tree.
Holly and yew however are rare, as are specimens of the endemic
Sorbus anglica and of wild service.
Spurge laurel is unusually
common particularly on the rockier
slopes, and privet occurs extensively. Under more open conditions
spindle and dogwood occur. Ivy is abundant but honeysuckle is not
common and traveller's joy is rare.
The dominant species of
the ground flora are dog's mercury and ivy
and widespread associates include Ranunculus ficaria, Anemone
nemorosa, Endymion non-scriptus, Primula vulgaris, Galeobdolon
luteum, Euphorbia amygda-loides, Campanula trachelium, Lithospermum
purpuro-caeruleum, Geranium robertianum, Viola spp., Colchicum
autumnale and Phyllitis scolopendrium.
The fauna includes a characteristic
range of species with no
particular rarities.
The Mendip Woodlands are
an interesting and floristic-ally rich
variant of the ashwoods found throughout Britain
on Carboniferous Limestone.
Rodney Stoke is the best example of the
drier facies of this woodland type. The woodland interest is
enhanced by the limestone grassland and abandoned agricultural land
which also occur in the reserve.
(b) Asham Wood
ST 7045.
195 ha
This wood lies on a steep
limestone gorge with a cliff and alluvial
floor. The western area is a plateau woodland. The presence of a
stream is an unusual feature of these Mendip Woodlands.
Ash is dominant but there
is a very extreme variety of trees and
shrubs. Small-leaved lime is common and other tree associates are
wych elm, pedunculate oak, gean, birch species, alder, yew (rare),
and field maple. The shrubs include dogwood, hazel, hawthorn,
spindle (rare), holly (rare), crab apple, blackthorn, blackcurrant,
gooseberry, sallows, whitebeam, rowan, elder, wayfaring tree and
guelder rose.
The ground flora of Asham
Wood contains a great variety of limestone
species although it is unusual that Daphne laureola and Lithospermum
purpurocaeruleum are absent. Particularly notable plants here
include Polygonatum multi-florum, Convallaria majalis, Dipsacus
pilosus, Colchicum autumnale, swarms of the Geum hybrids (G. urbanum
x G. rivale), Vicia lutea and V. sylvatica.
In addition rare Diptera
have been recorded as well as the wood
white Leptidea sinapis butterfly and the rare mountain Bulin snail
Ena montana.
The importance of this
floristically outstanding Mendip ashwood has
long been recognised and it represents the wetter facies of this
woodland type (cf. Rodney Stoke).
(c) Ebbor Gorge
ST 5248.
45 ha.
The site is on the south-west-facing
slope of the Mendip hills and
consists of a steep-sided gorge in Carboniferous Limestone together
with an associated tributary valley. Added interest is given to the
site by caves of palaeonto-logical value. The canopy of the mature
woodland is dominated by ash and pedunculate oak. Other species
present are wych elm, beech and hornbeam (rare). The understorey,
together with the scrub that is a feature of the area, contains a
range of species and includes field maple, traveller's joy, dogwood,
hazel, spindle, ivy, holly, buckthorn, small-leaved lime, wayfaring
tree and guelder rose. The woodland has been managed in the past and
most has been coppiced to some extent.
The ground flora is indicative
of the basiphilous nature of the
site, dog's mercury, wood anemone, bluebell and Asperula odorata
being abundant together with primrose, Sanicula europaea, Ajuga
reptans, Circaea lutetiana, Galeobdolon luteum, and Viola sp. A more
mesophilous vegetation is represented by patches where bracken,
Lonicera periclymenum, bramble and grasses are present. In the
sheltered gorge a damp woodland facies is found; bryophytes are
abundant as is Phyllitis scolopendrium. Scree areas are present
within the woodland area in which scattered ash regeneration is to
be found together with plants of Geranium robertianum.

Grade 2
An attractive and varied
woodland, formerly coppiced, on
Carboniferous Limestone.
The tree layer is dominated
by pedunculate oak with small-leaved
lime and wych elm locally abundant. In addition there is field
maple, ash, gean, common lime and English elm. The Sorbus spp. are
particularly interesting; S. torminalis occurs, as does S. aria and
the hybrid between them. A Sorbus close to S. rupicola is also found
here.
The shrub layer has abundant
hazel with dogwood, hawthorn, spindle,
abundant holly, privet, crab apple, currant, Rosa spp., wayfaring
tree and guelder rose. The field layer is dominated by bramble,
Brachypodium sylvaticum and dog's mercury but a very wide range of
calcicolous species also occurs.
This is a fine example
of a mixed deciduous woodland with a rich
variety of plant species. The Sorbus spp. need further study.

W.I22. CANNOCK
CHASE, STAFFORDSHIRE
sj 9818.
880 ha
Grade 2
Most of the site is covered
by heather heathland, grading into
valley fen and bog, but the woods occupy a substantial part of the
area, particularly in the north. Four main woodland types can be
recognised:
1 Oak-birch woodland. Quercus
petraea and Betula verrucosa form a
closed canopy over much of Brocton Coppice, but large clearings
exist, and the margin of the wood grades into surrounding heathland.
The oaks are clearly much older than the birch, perhaps 150-200
years in most cases, with a few individuals of greater age.
2 Birch woodland. Betula
verrucosa woodland occurs in the vicinity
of Brocton Coppice and elsewhere in small clumps.
3 Alder coppice. The Sherbrook
valley has alder coppice along most
of its length.
4 Willow scrub. Contrasting
strongly with the Sherbrook valley, the
Oldacre valley has a discontinuous line of Salix cinerea in the
marsh of the valley bottom.
The open heath is invaded
by trees and shrubs and birch woodland is
the most widespread serai stage. Other species also occur, notably
sycamore in the Sycamore Hill area, Scots pine and beech in the
southern area, hawthorn in the vicinity of Brocton Field,
pedunculate oak particularly among the birch in the Oldacre valley
and gorse at various points on the heath.
Bracken is dominant over
some areas and apparently on the increase
in others. The heathland is a noted locality for hybrid Vaccinium
myrtillus and V. vitis-idaea (Vaccinium x intermedium). Empetrum
nigrum is also present.
There are several valley
bogs, reminiscent of those in the New
Forest. The best has a large expanse of Thelypteris palustris and
Equisetum sylvaticum, with a rich assemblage of bog plants including
Anagallis tenella, Carex pulicaris, C. dioica, C. hostiana, Drosera
rotundifolia, D. anglica, Eleocha-ris quinqueflora, Hydrocotyle
vulgaris, Orchis fuchsii, Par-nassia palustris, Pinguicula vulgaris,
Vaccinium oxycoccus and Valeriana dioica. Narthecium ossifragum
occurs in one of the valleys.
The insect fauna of the
whole area is extremely rich. Two of the
most notable Lepidoptera are Stilbia anomala and Enargia paleacea.

SK 0955.
325 ha
Grade 2
The site follows the valley
of the River Manifold from Ecton
southwards towards Ham and incorporates part of the valley of the
River Hamps. The valleys contain woodland and scrub as well as
grassland. The woodlands are similar in many respects to the ash
woodlands of the Derbyshire Dales but exhibit some unusual features.
Thus old oak trees of Quercus robur and Q. petraea occur in several
places; and
holly is present, both as scrub and as a component of
established woodland. These features reflect some of the
characteristics of woodland under more oceanic conditions and
indicate a somewhat different climate on the extreme west of the
Peak District.
The woodlands of the Manifold
Valley show an extremely wide range of
variation in canopy structure and ground flora.
The grasslands included
within the site are on the whole damp and
well grazed. Agrostis spp. are generally dominant, but variations
occur according to slope and aspect. Potentilla tabernaemontani,
Carex pulicaris and Parnassia palustris are noteworthy amongst the
herbs.
Rare plant species present
include Polemonium caeruleum, Daphne
mezereum, Hordelymus europaeus, Festuca altissima, and Cardamine
impatiens. Daphne laureola, uncommon in the Peak District, is also
present.
The area is also of interest
for its karst topography. During
periods of dry weather the River Manifold disappears down a series
of swallets just below Wettonmill and the water resurges from
springs at Ham Hall about 11 km downstream. Thors Cave is an
impressive rock shelter perched on the side of the valley.

TL 7573.
80 ha
Grade i
Woodland forms an important
component of the interesting habitat
complex of this Breckland site, and shows a range of types serai to
dry heath and to rich-fen. The dry parts of both heaths have a good
deal of birchwood (of both birch species), varying considerably in
stature and stocking density of the trees. There are dense thickets
and pole stands with little but litter beneath, but more open birch
growths have either bracken or heather with well-developed carpets
of the common acidophilous heath and woodland mosses. On Tuddenham
Heath, dense swards of Carex arenaria occur within the birchwoods in
places. There are scattered trees of Scots pine and oak, but though
oak seedlings are numerous on the heaths, few survive, perhaps as a
result of roe deer browsing or unfavourable soil conditions. Where
the ground becomes damper, there is a change
beneath the birch to a
field layer with Deschampsia cespitosa,
Molinia caerulea, Agrostis stolonifera and abundant Lonicera
periclymenum. There are ferns such as Dryopteris austriaca, D.
spinulosa, D. filix-mas and Athyrium filix-femina, and mosses here
include Eurhynchium praelongum, Mnium hornum, M. undulatum and
Aulacomnium androgynum. In still wetter places within the
birchwoods, there are transitions to fen communities with Phragmites
communis, Fili-pendula ulmaria, Lycopus europaeus, Mentha aquatica,
Eupatorium cannabinum, Iris pseudacorus, Urtica dioica, Equisetum
palustre and Carex acutiformis. Ash plantation probably has less ash
than formerly, as there are some large dead trees of this species,
but ash and alder are mixed with birch in the damper part of this
wood, which also has an abundance of Thelypteris palustris. Towards
the River Lark (OW.ig), the birchwoods give way to dense areas of
willow carr, mainly of Salix cinerea, which grade into open fen
communities.

W-35. FELSHAMHALL
AND MONKS PARK WOODS, SUFFOLK
TL9357- 7° ha
Grade i* Thes e two contiguous
woodlands are ancient primary
woodland which has been managed as coppice and coppice-with-
standards for many centuries, but unlike most other woods of similar
origins in East Anglia, these have been coppiced on a commercial
scale up to the present time and have thus suffered less floristic
deterioration than those sites in which the coppice cycle has been
discontinued. Felshamhall is almost certainly the demesne wood of
Bury St Edmunds Abbey and Monks Park is likewise a park given to the
Abbey in the early twelfth century.
Four main types of woodland
have been distinguished: (i) the typical
oak-ash-hazel-maple-type of the boulder clay woods; (2) a wet
variant of this, with alder and Salix alba (this feature is very
unusual); (3) an oak-birch woodland where the boulder clay gives way
to sand and sandy gravel; and (4) secondary woodland, occupying the
sites of former clearings which were the launds of the old mediaeval
park. Associated with these types are distinctive ground flora
communities and important transition types, including the Primula
elatior- Filipendula ulmaria-Mercurialis perennis association
widespread in these woods. In this site bluebell is unusually rare.
Bracken and Sarothamnm scoparius occur on the sand, and a totally
distinctive assemblage with Neottia nidus-avis marks the secondary
woodland. A total of over 280 species of vascular plants has so far
been recorded, including all the tree species of the primaeval mixed
oak forest.
Historical evidence of
woodland continuity is good. Coppicing was
practised at least as early as the thirteenth century. As in many
boulder clay woods, the oak standards were felled some time ago and
not replaced, but unusually a good natural crop of young oaks is
developing to restore the oak canopy.
The fauna is apparently
unknown, though among the birds there is an
obvious abundance of woodland warblers, but on botanical and
historical grounds alone this site is regarded as the most important
of the ancient boulder clay woods of East Anglia. Its vascular flora
is already known to be richer than almost every other wood in
eastern England. The record of its existence and management is
unusually detailed as far back as the twelfth century. As such it is
a site of both botanical and archaeological importance.

W-33- HINTLESHAM
WOODS, SUFFOLK
(a) Hintlesham and Ramsey
Woods TM 0743. 80 ha
(b) Wolves Wood TM
0544. 40 ha
Grade 1
These distinct woodlands
are separated by less than 0.5 km of arable
land and as they are complementary they have been considered as a
single aggregate site. The larger wood is a complex of two ancient
woods, Hintlesham and Ramsey, and secondary woodland of various
dates surrounding and linking the two ancient nuclei. Wolves Wood is
likewise mainly
ancient woodland with some secondary extensions,
which probably include the small Keeble's
Grove, continuous with
Wolves Wood.
These woods lie on boulder
clay of a lighter and less chalky type
than is found in the east Midlands and western parts of East Anglia.
The clay soil is mainly neutral or mildly acidic with only small
areas of a calcareous nature. Much of the woodland is the oak-hazel-
birch combination with much ash on the wetter sites, but the
heavier, neutral or slightly calcareous soils have relatively little
birch and some maple. Other calcifuge coppice types occur, notably
lime coppice in Hintlesham Wood and hornbeam coppice mainly in
Wolves Wood. Part of Wolves Wood occupies a basin situation in which
the water table is high and aspen and willows are abundant in the
coppice. In addition there is a series of secondary elm woodland in
the Hintlesham part, and a series of elm coppice types in the
ancient parts of Wolves Wood, some of which have apparently invaded
other coppice types whilst others are evidently non-invasive and of
local origin. There is a range of ground flora communities
corresponding with the wide range of edaphic conditions, which
includes a number of local woodland species such as Paris
quadrifolia and Helleborus viridis.
These woods have an unusually
complex system of earthworks and
apparently have a good historical record. Only Ramsey is a complete
ancient wood, but a substantial portion of the other ancient woods
have survived. All the existing woodland is semi-natural. Many
primary woods or parts thereof survive in east Suffolk, and a
proportion of them have been examined in detail recently, but none
has been found which surpasses these two as examples of the coppice
types on the lighter glacial deposits.

W-37. SOTTERLEY PARK, SUFFOLK
TM 4685.
205 ha
Grade i
This is one of the finest
examples of the deer park habitat
remaining in East Anglia. The park is at least of early mediaeval
origin and hence may have been formed by the enclosure of more or
less primary forest. The records indicate that it was even more
wooded in the seventeenth and eighteenth centuries than it is today
but it still contains numbers of ancient oaks and areas of old
woodland.
Four main habitat types
are recognised in the park:
(i) The ornamental landscaped
garden area around the gardens of the
Hall itself with both woodland and open parkland areas containing
native trees and some exotics such as walnut.
(ii) The open parkland
north-west of the Hall with avenues and
groups of elms and ash trees, many of which are of great age, and
also some sycamore.
(iii) The areas of very
old oak woodland, or oak in open canopy in
which are also old ash trees.
(iv) Areas of enclosed
woodland largely oak but with beech,
chestnut, hazel and other trees. Of these four habitats the first
three are most important. Many of the oaks are of huge size and
great age and the epiflora is very rich. The fourth type appears
less rich but needs further study.
The epiphyte flora of 89
species of lichens and 14 bryo-phytes is
the richest known in East Anglia today for an area of comparable
size. The most notable lichens are Anaptychia ciliaris, Calicium
dbietinum, Chaenotheca brunneola, Norman-dia pulchella, Opegrapha
sonedufera, and Ramalinafraxinea. Other species found in abundance
here include Opegrapha lyncea, Rinodina roborus and Hechancha
premnea.

W-34- STAVERTON PARK, SUFFOLK
TM 3550.
85 ha.
Grade i
This site lies on freely
drained, glacial sands wholly within the
boundary of a former mediaeval park. Documentary evidence suggests
that this is one of the few sites on the Suffolk Sandlings which
contains primary woodland. This is supported by the absence of a
podsol profile in an area where such soils are widespread following
woodland clearance, and by the presence'of a rich assemblage of
corticolous and lignicolous lichens.
The existing woods are
in two parts. The Park is occupied by open
woodland of ancient pollarded oaks (Quercus robur) and holly, with
local dominance of mature birch (both species) over a poor ground
flora dominated by bracken and Holcus mottis. The Thicks has
developed from this in the last 170 years, by an upsurge of holly,
which now forms an almost closed canopy with the oak, beneath which
ground flora is absent. Among these are some huge hollies, reaching
over 21 m in height and over 3 m in girth. Indeed, the site is
remarkable for the profusion of individuals of oak, holly birch,
rowan and hawthorn sharing the extreme forms adopted by these
species after long and vigorous growth. The only locally rare
vascular plant is Corydalis claviculata, but the epiphytic lichen
flora includes a number of rare and Atlantic species, such as
Haematomma elatinum, Lecanora cinnabarina, Thelotrema lepadinum,
Phaeographis ramificans, Stenocybe septata, Phlyctis agelaea and
Opegrapha lyncea.
In addition to the floristic
and historical interest, Staver-ton
Park and its immediate environment have a number of relatively rare
birds, such as sparrowhawk and stone curlew. The invertebrate fauna
is unknown in detail but on casual inspection appears to be rich.

W.20. COLTERS
HANGER, SURREY
TQ 0448.
35 ha
Grade 2
This wood occupies a south-facing
slope running down to the River
Tillingbourne. Like Scords Wood it has a range of woodland types
zoned on this slope to correspond with marked differences in soil
nutrient status and water content. The highest zone over dry, sandy
soil is oak woodland over a field layer dominated by bracken. The
intermediate zone is mixed deciduous woodland of oak standards and
hazel coppice with wych elm, ash and field maple over a basi-philous
ground flora including Mercurialis perennis, Adoxa moschatellina and
Campanula trachelium. On a springline below is alder woodland
containing Chrysosplenium oppositi-folium, C. alternifolium,
Equisetum telmateia and Cardamine amara.
This site is selected partly
to represent eutrophic alder carr in
the south-east, where it is particularly characteristic of
springlines and the floors of gills and valleys. It is, however,
preferred to other, more extensive alder carrs in the district (e.g.
at Iping) because of the diversity of woodland types present,
related to geological diversity in the escarpment at different
levels.

W.2i. GLOVER'S WOOD, SURREY
TQ 2240.
95 ha
Grade 2
This is a substantial wood
which lies on neutral and mildly acid
clays across the incised valley of the Welland Gill. Two main
woodland types may be distinguished. On the steep-sided gill there
is hornbeam coppice with a limited proportion of ash, wych elm,
maple, hazel and small-leaved lime, and a ground flora with
Galeobdolon luteum, Endymion non-scriptus, Rubus-Section Sylvatici
and patches of Mercurialis perennis. This woodland appears to be
primary, and can be distinguished from the plateau woodland which
has developed in the last century or more on abandoned fields. Much
of the plateau woodland is of birch, hazel and pedunculate oak, but
numerous other tree and shrub species are present, including
hornbeam, which is now invading from the former hedgerows. The
ground flora is mainly .Rates- Section Sylvatici, honeysuckle
and small patches of bracken.
This site is one of many
in the Weald with a mixture of primary and
secondary woodland, and relatively uniform coppices. It is selected
partly because of its large size and also because it has small
populations of lime and wych elm which are rare in the Weald.

W.I9- STAFFHURST
WOOD, SURREY
TQ 4148.
50 ha
Grade 2
Staffhurst is a former
common woodland lying on Weald Clay.
Structurally it is very irregular coppice-with-standards in which
cutting has been sporadic rather than systematic. The dominant
species, pedunculate oak, beech and hornbeam, all occur as
standards, but only the latter two have been coppiced. The shrub
layer, in addition to the coppice species, contains holly and yew.
Throughout the wood the ground flora is dominated by bramble,
bracken and bluebell. Two subsidiary woodland types also occur. On
the western side is a small area of open woodland of ancient oaks
and yew, with a number of epiphytic lichens. On low-lying base-rich
and partly flushed areas a mixed deciduous woodland with oak,
hornbeam, ash, field maple and wild service occurs over a ground
flora including Brachypodium sylva-ticum, Mercurialis perennis,
Primula vulgaris and Sanicuia ewopaea, with the local sedge Carex
strigosa. Marginal to the Staffhurst Common is Butcherswood Bank, a
small area of hazel and hornbeam coppice with oak and birch as
standards.
Taken as a whole, this
wood is important as one of the few woods
with a wide range of structural types and age classes, associated
with a range of field layer communities.

Grade 2
Ashburnham is a former
mediaeval deer park lying on Tunbridge Wells
Sandstone and Wadhurst Clay, much of which is now arable. The
woodland is of two types, (i) closed, high forest of oak, beech,
birch and holly with planted sweet chestnut, and (2) very old, open
oak-beech woodland. Both types are overmature and contain a rich
assemblage of epiphytic lichens, second only to those in Bridge
Park, including species characteristically on holly which are not so
well developed east of the New Forest. The ground flora is limited,
but includes Dryopteris aemula on sandstone. In its general
character and many other features this site is similar to the
ancient oak-beech- holly woods of the New Forest.

W.8. BIGNOR HILL,
SUSSEX
su 9713.
160 ha
Grade i
Bignor Hill is at the southern
end of extensive woodlands situated
on the north- and east-facing Chalk scarp slopes. These woods are
not quite continuous, and stretch in a broken chain from Duncton
Down in the north to Great Bottom on the dip slope in the south.
Beech is dominant, with ash as a more or less constant associate.
The stand has a limited range of age, but recent thinning has
facilitated some regeneration, mainly of ash. Birch and field maple
are also present in the canopy, while the shrub layer of yew,
whitebeam, dogwood and spindle is reasonably well developed. Ground
flora communities cover the usual range from Mercurialis perennis-
Sanicula europaea on dry, calcareous soil to Endymion non-scriptus-
Rubus fruticosus on the deeper plateau soils. Local variations occur
on Duncton Hanger where, in a valley along a springline, a wych elm
woodland has developed; at Bignor Hill, where an ashwood on scree
includes the only locality in the south-east for Thelypteris
robertiana; and at Great Bottom, where on the west side there are
some of the largest and possibly oldest pollarded beeches in the
south-east.
There are many other stands
of beechwood on the South Downs, but
those at Bignor Hill are regarded as the best developed, with a
number of local variations related to geological and edaphic
differences.

W.II. EBERNOE COMMON,
SUSSEX
su 9727.
110 ha
Grade i
Ebernoe Common and Willand
Wood together form a continuous block of
woodland with a wide range of structural, floristic and soil types
in the western Weald. The underlying strata range from heavy clay to
sandstone and limestone, giving rise to the three main soil types of
the area.
Ebernoe Common has three
main woodland types. The most extensive is
mature, closed beech woodland with some pedunculate oak and a dense
understorey of holly with some yew. Some beech have fallen recently
to produce gaps in which regeneration occurs sparingly. Along the
eastern side and over base-rich soils, younger mature woodland of
field maple, pedunculate oak and ash is found, with a few beech and
a sparse understorey of holly. At the northern end a third type
occurs, open ancient woodland of oak and beech with scattered
thickets of holly. Not all the Common is wooded: large areas remain
under grass and bramble, and other parts of former grassland are now
occupied by scrub of gorse, blackthorn and willow with thickets of
oak and birch saplings. The ground flora, virtually absent beneath
the closed beech canopy, varies considerably between the Mercurialis
perennis-Primula vulgaris-Sanicula europaea community of the base-
rich soils to Rubus fruticosus and Deschampsia cespitosa on the
clays. The local species include Narcissus pseudo-narcissus, Ruscus
aculeatus and Carex strigosa. The epiphyte flora is fairly rich, but
lacks a number of old forest indicators. In addition to the woods,
scrub and grassland, the Common contains large ponds and marsh areas.
Willand Wood consists of
coppice-with-standards typical of West
Sussex, with pedunculate oak standards over mixed coppice of
hornbeam, hazel and ash. The ground flora is dominated by wood
anemone, bluebell and primrose.

W.I4- FAIRLIGHT,
ECCLESBOURNE AND WARREN GLENS, SUSSEX
TQ 8511.
205 ha
Grade i
The Lower Cretaceous rocks
of the Weald are exposed along this
stretch of coast. Magnificent cliff sections include the Fairlight
Clays (type locality), Ashdown Sand and Wadhurst Clay. Considerable
slipping and erosion has occurred creating a distinct undercliff
zone which is heavily overgrown with scrub. Isolated boulders in
this zone support a number of interesting bryophytes including
Tortula cuneifolia, T. marginata, Desmatodon convolutus and
Lophocolea fragrans in its only station east of Dorset.
The three glens have been
cut down through the Wad-hurst Clay,
Ashdown Sand and in the case of Fairlight and Warren Glens through
the Fairlight Clays as well. The valleys produced have steep sides
covered in parts with mature woodland consisting of oak, beech, and
ash with yew, holly, field maple, birch and alder which grade into a
coastal scrub towards the cliff edge consisting of wind-pruned
thickets of privet and blackthorn. The ground flora varies from
bracken-dominated communities on the sands, to communities of
Mercurialis perennis with Carex pendula and Epipactis purpurata on
the clays. Flush communities with for example Chrysosplenium
oppositifolium and Allium ursinum occur with the alder.
Floristically, Fairlight
Glen is of considerable importance for the
presence of the rare hepatic Dumortiera hirsuta and the moss
Fissidens rivularis in their only stations east of Devon and a
number of lichen species characteristic of old forest, e.g.
Normandina pukhella, Dimerella lutea and Graphina anguina. Its
coastal situation is rare in lowland English woods.
The area known as the Fire
Hills was at one time covered with a low
growing heath community of Calluna vulgaris and Erica cinerea; this
has now been largely replaced by Ulex emopaeus.

W.IO. KINGLEY
VALE, SUSSEX
su 8211.
160 ha
Grade I*
Within the general area
of Kingley Vale only part of the land is
occupied by woodland. This lies on the south-facing Chalk slopes and
on clay in the valley bottom. Two broad woodland types occur, yew
woodland on Chalk and oak on the clay, of which the former is much
the more extensive. The yew woodland is almost pure in parts, but
with a range of age classes. Elsewhere within the yew-wood, ash is
common, and whitebeam, holly and blackthorn occur sparingly. Juniper
formerly occurred there abundantly but successional changes have
greatly reduced its extent. The field layer is absent, or
represented by sparse development of, for example, Fragaria vesca
and Brachypodium sylvaticum. The woodland on clay is dominated by
pedunculate oak and ash, with an understorey of yew, holly and
hawthorn.
The Kingley Vale woodland
is selected as a representative of yew-
dominated stands on calcareous soils. As such it is regarded as the
most important site in Britain and is reputed to be the best yew-
wood in Europe. Though yew woodland occurs elsewhere, e.g. Old
Winchester Hill, Blackcliff, Box Hill, the stands are either less
extensive or are mixed with other, taller species such as beech. A
further important feature of Kingley Vale is the presence of all
stages in the development from scrub
on grassland to mature yew
woodland. See also L.Q.

W.l8. PARHAM
PARK, SUSSEX
TQ 0514.
280 ha
Grade 2
Parham Park lies on Folkestone
Sands at the foot of the South Downs.
It is a mediaeval deer park which still contains deer. Parts of the
woodland comprise open forest of huge, ancient oaks, probably the
best remaining stand of overmature oaks in south-east England. North
Park Wood is closed canopy high forest of beech and oak with an
under -storey of holly. Despite the presence of sheltered valleys,
the vascular flora is very limited, but the epiflora is richer than
all other sites in the south-east except Bridge Park and Ashburnham
Park. Among the 103 lichen species are Thelopsis rubella and
Ophegrapha rufescens, known nowhere else east of the New Forest.

W-9- SAXONBURY
HILL/ERIDGE PARK, SUSSEX
TQ 5734.
600 ha
Grade i*
This site comprises an
ancient deer park, a more recent park now
used for deer, and adjacent woodlands on Saxonbury Hill, situated in
the High Weald. The parks, particularly the northern half of the Old
Park, have an open woodland of
ancient oaks, maple, ash
and beech beneath which the ground
vegetation is a mosaic of bracken, Molinia caerulea and heather
heath, and in the lower parts on Wadhurst Clay a relatively rich
woodland ground flora has developed. Small, low-lying areas are
occupied by alder carrs, small areas of calcareous fen and some
acidic flushes. Saxonbury Hill includes a mixture of woodland types.
Mature, closed oak-beech forest occurs on plateau areas where yew
and holly are also frequent. In the valley, alder occurs beside the
stream, and on flushed parts of the slopes near the valley bottom.
On the drier slopes woodland of oak and birch occurs locally.
Taken as a whole the site
has one of the richest epiphytic lichen
floras of any single park in Britain. So far 167 species have been
recorded. It is the only site in south-east England where a well-
developed Lobarion association occurs. Numerous species
characteristic of old forests have been recorded, including Lobaria
pulmonaria, L. laetevirens, Nephroma laevigatum, Parmeliella
plumbea, Leptogium lichenoides, L. minutissimum, Buellia schaereri,
Parmelia crinita, Xylographa vitiligo and Dimerella lutea. Bryophyte
epiphytes include Frullania fragilifolia and Orthotrichum
stramineum, which are otherwise unknown in south-east England. In
Saxonbury Hill woods there is a small sandrock outcrop with
Dryopteris aemula and Hymenophyllum tun-brigense, and a number of
western bryophytes such as Scapania gracilis and Bazzania trilobata.
Although much of the central
area of the Old Park has been reseeded,
this site is undoubtedly one of the most important of all the
ancient parklands selected, because the woodlands are diverse and
the epiphyte flora is unsurpassed.

W.I2. WAKEHURST
AND CHIDDINGLY WOODS,
SUSSEX
TQ 3331, TQ 3432.
150 ha
Grade i
These woods occupy the
steep slopes and bottoms where the Ardingly
and Cob Brooks have cut deeply incised valleys and exposed large
areas of Tunbridge Wells Sandstone. At Chiddingly, the woodland on
the plateau has been largely modified, consisting now in parts of
scrub, coppice and planted pine with a number of exotic tree
species. However, on the rocky slopes below the sandrock outcrops, a
dry oak (mainly pedunculate) wood with birch, yew, holly and some
beech, shades ground covered in large boulders. At points in the
ravine where the soil is deep alluvium there is a local development
of ash and alder woodland, grading to ash-oak on drier ground.
Within this woodland there are a number of mature trees, some
planted exotics and a local spread of rhododendron. The sandrock
outcrops, which are the most extensive, sheltered exposures of the
formation, have the richest development of the associated
communities of
Hymenophyllum tunbrigense and suboceanic bryophytes,
Dicranum scottianum, Orthodontium gracile, Tetraphis browniana,
Bazzania trilobata, Scapaniagracilis, Pallavicinia lyellii,
Harpanthus scutatus, Blepharostoma trichophyllum, Scapania umbrosa,
Odontoschisma denudatum, Tritomaria exsectiformis and Lepidozia
sylvatica.
Wakehurst Woods are part
of one of the most extensive stands of High
Weald gill woodland with one of the largest sandrock outcrops. Much
of the woodland is oak or oak-beech mixture, mature but with few
really ancient trees, but along springlines alder and ash woodland
occurs. Woodland types occurring in small quantity are open woodland
of birch and oak, and areas of coppice, principally of sweet
chestnut and hazel on lower slopes. At the higher levels bracken,
bilberry, Deschampsia flexuosa and Lonicera peri-clymenum dominate
the ground flora; whilst at lower levels on the clays, bramble,
primrose, bluebell and wood anemone are prevalent, and flush
communities with Carex laevigata and Chrysosplenium oppositifolium
occur with the alder. The epiphytic lichen flora is moderately rich,
but includes no exceptional occurrences. The ground flora includes
Dryop-teris aemula and Wahlenbergia hederacea. The most important
feature is the community of the sandrock outcrop, second only to
those in Chiddingly Wood, which includes Hymenophyllum tunbrigense
and a number of rare bryophytes and saxicolous lichens.
At their nearest point
these two woods are no more than 200 m apart.
Collectively they form easily the richest of the sandrock
communities. The two sites complement each other in that some of the
characteristic species absent in Chiddingly are present in
Wakehurst, and vice versa. In neither case are the tree and shrub
strata of particular importance, except that the continuity of a
substantial tract of high forest with few large clearings is
essential for the continued existence of the sandrock communities.

W.I3- THE MENS AND
THE CUT AND BEDHAM ESCARPMENT, SUSSEX
TQ 0223. I9° na
Grade i
This extensive common woodland
lies along the parish boundaries of
Kirdford and Fittleworth from Idehurst Hurst to the Bedham
Escarpment. For the most part it is on flat, low-lying ground
drained by the headwaters of the River Arun, but at the south- west
end it rises to a small hill. This is where the sandy Hythe Beds
outcrop above Ather-field Clay, and give rise to acidic, sandy soils
which are nevertheless imperfectly drained. Most of the site lies on
Lower Weald Clay, but through Hammonds Wood there are numerous
sandstone bands, and Paludina Limestone outcrops in a narrow band
across The Cut.
The woodland is mostly
high forest of sessile and pedunculate oaks,
beech and locally ash, wild service and the birches. There is a
tendency for beech to be dominant over a holly or yew understorey on
the lighter soils, and for oaks and ash to be dominant over a mixed
shrub layer on the heavy soils. A few ancient oaks are present, but
most of the trees are probably less than 100 years old. Even so, the
structure of the wood is one of its important features, for all
stages of the regeneration cycle are well represented. The ground
vegetation is limited for a site of this size, but many
characteristic woodland species are present, including Carex
pendula, C. strigosa and Milium effusum. There is a moderately rich
bryophyte flora which includes, at the Bedham end, a number of local
species on small boulders, Campylostelium saxicola, Brachydontium
trichoides, Mar-supella emarginata and M. ustulata. The epiphytic
lichen flora is not fully known, but is certainly among the richest
for woodland in the south- east. Recent detailed examination of the
fungal flora has revealed that, in this respect, The Mens and The
Cut is one of the richest woods in Britain, and may even be the
richest: included in the list are three Russula spp. not known
elsewhere in Britain, and another two known only from one or two
other sites. Entomologic-ally, this site is regarded as extremely
rich, especially in the Crimbourne Wood area, with many extremely
rare beetles on record and thriving populations of most of the
woodland butterflies.

ITCHINGTON AND UFTON WOODS, WARWICKSHIRE
SP 3862.
80 ha
Grade i
These woods are situated
on a gentle north-east-facing slope, rising
to a plateau at 90-120 m, with soils which vary from medium clay to
loam. This is a fine example of oak-hazel coppice woodland that is
still managed as such. There are well grown standards of pedunculate
oak, open grown and up to 15 m in height; the coppice layer is
dominated by vigorous hazel which is coppiced in rotation, several
different age classes being present. Other shrubs are present
including hawthorn, roses, wayfaring tree and dogwood.
The ground flora may be
divided into two main types. The upper parts
of the slope and the edge of the plateau are dominated by species
such as Rubus fruticosus agg., Deschampsia cespitosa and Carex spp.
In the damper areas and along the ditches there is an abundance of
Geum rivale. On the lower slopes the soil is a rich loam and there
is a meso-philous field layer dominated by dog's mercury, bluebell
and primrose,
with occasional patches of Paris quadrifolia. There
are a number of orchids in the wood including Listera ovata,
Platanthera bifolia, Neottia nidus-avis and Epipactis helleborine.

Wiltshire-Dorset county boundary. Within this the Rushmore Park
Estate comprises a large wooded plateau area and slopes leading down
to chalk grassland in the valley. The woodland includes what may be
the largest remaining area of worked hazel coppice, with pedunculate
oak and some ash and maple standards. On the plateau Clay-with-
Flints soil there is high forest of pedunculate oak and some beech.
In the valley, grading into open grassland, is closed woodland of
ash and field maple with some pedunculate oak, beech, yew and holly
and some coppiced hazel. The ground flora throughout is rich with
abundant Mercurialisperennis, Sanicula europaea and Galium odoratum.
The ash- maple woodland is notable for epiphytes, with abundant
Viscum album and the local cryptogams Leptodon smithii, Lobaria
pulmonaria and Sticta limbata.

FOREST, WILTSHIRE

930 ha
Grade 2
Savernake was one of the
ancient Royal Forests, and is largely
managed commercially. Most of the area lies on Clay-with-Flints. The
woodland is open pedunculate oak, with numerous huge and ancient
trees, which has recently been interplanted with oak. As in most
ancient parkland woods the ground flora is limited, but the
epiphytic lichen flora is outstandingly rich, over 100 species
having been recorded recently by F. Rose. It includes species of a
more continental distribution than are found in the more coastal New
Forest, e.g. Caloplaca herbidella. Amongst the bryo-phytes are the
local species Pterogonium gracile and Dicranum montanum.
Though this site is of
less importance than the New Forest, the
average age of its oaks is considerably greater and the epiphytes
are less oceanic.

W.I32. CHADDESLEY-RANDAN
WOODS, WORCESTERSHIRE
so 9273.
170 ha
Grade 2
These woods lie on Keuper
Marl from which a poorly drained, rather
acidic, loamy clay soil develops, but the higher ground is capped by
glacial drift of a sandy and gravelly character on which freely or
excessively drained, light, strongly acidic soils have formed. The
woodland is almost entirely dominated by mature oak high forest in
which both native species are represented. There is a tendency for
most oaks on the light soil to be Quercus petraea and most on heavy
soils to be Q. robur, but this is not a particularly close
relationship and mixed populations are widespread. A coppice and
shrub layer is present throughout, although it is thin on the most
acid soils, and consists of a mixture of species, including hazel,
ash, alder and birch. A considerable number of native tree and shrub
species are present in small numbers. Along the deeply incised
stream lines, influenced by calcareous water, a rich alderwood has
developed.
A number of local plant
species are present, including Epipactis
purpurata and Carex strigosa, but no nationally rare species are
recorded. The fauna includes the rare terrestrial caddis fly
Enoicyla pusilla.
The scientific interest
is not confined to the woodland for a number
of small herb-rich meadows and green lanes occur within the woods.
One in particular, in the centre of Chaddesley Woods, occupies a
receiving site on heavy clay, and has developed as a meadow/marsh in
which Serratula tinctoria, Silaum silaus and various Dactylorchis
spp. are present.
Chaddesley-Randan Woods
are undoubtedly the most important to nature
conservation of the group of woods which were formerly within
Feckenham Forest. The others, centred on the parish of Himbledon,
are much more uniform where they survive as native woodland. The
richest woods in this group have recently been clear-felled, but it
is doubtful whether even they were richer than Chaddesley-Randan
Woods.
These woods have been included
in the Review primarily as an
extensive and rich example of the oak woodlands in the West
Midlands, and are more closely related to the Wealden oak woodlands
than the coppice-with-standards woods typical of much of the
Midlands. In so far as they possess significant stands of sessile
oak woodland on acidic, freely drained sandy soils, in association
with pedunculate oak-wood in an apparently natural distribution,
Chaddesley-Randan Woods are similar to Wyre Forest (W.i2i).

W.I37- BIRK
FELL, WESTMORLAND
NY 4018.
ioo ha
Grade i
This is the most extensive
continuous stand of juniper in Lakeland,
and equals or exceeds that of Upper Teesdale in size. Unlike juniper
scrub considered under the lowland calcareous habitats it grows on
leached skeletal brown earths over Borrowdale Volcanic rocks and has
few basi-philous associates, though there are some patches of richer
soil locally. The relationship with woodland is fairly close and
this juniper scrub passes below into a stand of birch-wood which
occupies the base of the slope. Towards the edges of the wood, the
junipers are smaller, probably as a result of grazing by sheep and
red deer. The individual trees of the Tynron Juniper Wood have a
generally greater stature, but Tynron Wood covers a much smaller
area than the Birk Fell juniper wood. In the Highlands juniper
scrubs mostly occur as the shrub layer of pine and birch woods, and
stands on open moorland tend to occupy damp hollows rather than dry
slopes as in Lakeland.
The birchwood may be a
serai derivative of sessile oak-wood, for it
occupies the habitat held by the latter elsewhere in the Ullswater
valley. The field layer of this wood is virtually identical with
that of the other Lakeland oakwoods on acidic soils, and the
bryophyte communities are also typical, but with poor representation
of Atlantic species. The filmy fern Hymenophyllum wilsonii occurs
sparingly.

W.I38. HELBECK
AND SWINDALE WOODS, WESTMORLAND

135 ha
Grade i*
This is the northernmost
of the internationally important series of
ashwoods on the Carboniferous Limestone and lies on the Eden valley
scarp slope of the Westmorland Pennines, above Brough. Helbeck Wood
is on the frontal slope which rises in ridges and tiers of limestone
scar towards Little Fell at the southern end of the Cross Fell
range, while Swindale is the adjoining deep and cliff-lined valley
cutting this slope at the eastern end. The ashwood is fairly pure in
places, but there is locally a good deal of wych elm, and towards
the edges more open birchwood with hawthorn takes over. Oak is
scattered and there are varying amounts of hazel, aspen, rowan,
holly, gean and bird-cherry. Southern species of tall shrubs are
represented: Crataegus oxyacanthoides occurs sparingly here, its
northern limit; buckthorn is recorded; and there is a small amount
of spindle. The northern willow Salix phylicifolia occurs alongside
Swindale Beck. Non-native species such as larch, sycamore and beech
are present, but in rather small quantity, and they thus add to the
diversity of the woods rather than detract from their quality.
Parts of the woods are
ungrazed or lightly grazed, and there is a
rich development of herbaceous communities, with the usual Allium
ursinum-Mercurialis perennis types conspicuous, but also a variety
of others associated with more open conditions, especially on screes
and outcrops. The more local herbs include Myosotis sylvatica, Cepha-
lanthera longifolia, Convallaria majalis, Vicia sylvatica, Paris
quadrifolia, Aquilegia vulgaris, Campanula latifolia, Epipactis
helleborine, Rubus saxatilis, Geranium lucidum, Cirsium
heterophyllum and Polygonatum officinale. On steep rocks are
Hippocrepis comosa and Car ex ornithopoda. The two rare horsetails
Equisetum pratense and E. hyemale grow within the site.
Other field communities
include the grassy type, dominated by
Brachypodium sylvaticum and there are also transitions to the
Sesleria albicans and Festuca grasslands of the open hillside. In
places there is dominance of bluebell with bracken, especially
around the lower edges of Swindale. Within Helbeck Wood is a small
tarn, with fringing calcareous marsh of sedges and 'brown mosses',
with an abundance of Primula farinosa and Valeriana dioica.
Altogether, the diversity of habitat and floristics, and the
gradation into other important upland communities, make this a most
important site. It is contiguous with the Appleby Fells grade i
upland site (U.22).

no ha
Grade 2
Naddle Low Forest is situated
at 200-400 m on the slope overlooking
the lower end of Haweswater and on both sides of a re-entrant valley
joining the main river just below the foot of the lake. The aspect
is mainly north-west, but on the spur between the two main sections
varies through north to east. The parent rock belongs to the
Borrowdale Volcanic Series, and contains calcite in places, so that
the soils vary from acidic to basic brown earths, while the slopes
are generally steep and locally precipitous. The poor soils of steep
ground have sessile oakwood, but birch locally replaces oak,
evidently through selective extraction of the latter. Ash-hazel wood
is well developed on the richer soils, and where the slope flattens
to the river, beyond the dam, there is a good mixed deciduous wood,
and alder-Care* swamp in places. The slopes are thickly strewn with
blocks and here there is a profusion of ferns and bryophytes.
Lightly grazed sections of the wood have herbs such as Geranium
sylvaticum and in open places there are soligenous mires with Juncus
acutifiorus and Primula farinosa.
Naddle Low Forest shows
much the same range of habitat and
vegetational variation as the Borrowdale Woods, but is regarded as a
second choice for the following reasons.
(i) There is a much lesser
representation of good oak and a
correspondingly greater amount of probably serai birch.
(ii) There is a smaller
extent of ash-hazel wood. .
(iii) There is a lesser
range of aspect.
(iv) Though luxuriant and
rich, the bryophyte flora is much poorer
in Atlantic species, probably because of the eastern position of
Naddle Low Forest.
Naddle Low Forest has the
advantage of being in two almost
continuous blocks and probably contains a few herbs not present in
the Borrowdale Woods.

W.I36. WHITBARROW
AND WITHERSLACK WOODS, WESTMORLAND
so 4487.
160 ha
Grade i
The area contains two main
blocks of woodland. On the west side in a
slight valley, below the west-facing Carboniferous Limestone scarp
of Whitbarrow Scar (see L.I36), is a large stand of high forest,
grading into scrub as the slope steepens. On the eastern, dip slope
of Whitbarrow Scar, is a much more heterogeneous woodland with a
mosaic of coppice, scrub and planted conifers on discontinuous
limestone pavement.
The high forest, extending
from Pool Bank to Wither-slack Hall,
consists of a mixed sessile oak-ash wood, becoming purer oakwood
near the road, where the rock changes to Silurian slate. This wood
is important for its relatively large area of tall, well-grown oak,
a relatively rare feature in this district where so much of the
woodland has been coppiced. Although the wood is ungrazed, the field
layer is not species rich, and the influence of the limestone is not
particularly obvious until the slope of the Scar is reached. Rubus
fruticosus is dominant locally, though R. saxatilis is also abundant
near the road. There is local abundance of Mercurialis perennis and
Brachypodium sylvaticum but the herb flora is not large. Thelypteris
phegopteris is locally luxuriant. Birch is quite abundant, there are
patches of hazel thicket, and dense ash regeneration occurs in
places. Wych elm is frequent and small-leaved lime occurs here in
one of its northernmost localities.
On the slope falling from
Whitbarrow Scar there is a belt of pure
yew- wood and above this a lower growth of oak, ash and hazel,
passing on the scarp to scrub with juniper, yew, hazel, birch,
buckthorn and Sorbus lancastriensis. There are old records of Daphne
mezereum.
To the west of the road
there is a change to ashwood on and beneath
a second, smaller, and east-facing limestone scarp. The flora here
is richer than that of the oakwood, with most of the typical ashwood
species, and more local plants such as Ophrys insectifera, and the
shady rocks have an abundance of calcicolous bryophytes.
The native woodland on
the dip slope is mainly a scrubby ash-hazel
growth, grading into sessile oak locally, and the field layer
contains much Brachypodium sylvaticum and Sesleria caerulea, with
Carex ornithopoda and Melica nutans quite plentiful. The grikes have
Phyllitis and Dryopteris villarii, and Epipactis atrorubens occurs
in more open places, while interesting bryophytes include the
northern Rhytidium rugosum and the southern Atlantic Marchesinia
mackaii. There was formerly a native colony of Allium schoenoprasum
near Rus Mickle. Basiphilous woodland herbs are well represented and
there are all transitions to open pavement with its characteristic
flora (see under Lowland Grasslands, Heaths and Scrub). Despite
conifer planting, which clearly causes surface acidification and
impoverishment of this interesting flora, it is apparent that there
will always be a patchy occurrence of native scrub and associated
field/ ground communities on the rockier, unplantable ground, and
this eastern area is included in this important grade i site for its
great botanical interest.

Grade 2
These form part of an extensive
group of woodlands at 90-150 m on
the steep sides of upper Rye Dale near Rievaulx, one of the deep
glens draining the south-western part of the North York Moors.
The woods lie on the west
slope of this valley and on both aspects
of the ridge bounding the east side. Soil conditions range from
acidic to strongly calcareous, and from dry to permanently water-
logged. On the acidic soils oak and birch dominate over a field
layer of Rubus fruticosus, Pteridium aquilinum, Vaccinium myrtillus,
Lonicera peridymenum and Luzula sylvatica. On calcareous soils,
mixed deciduous woodland of ash, field maple, wych elm, hazel and
small- leaved lime grows over Brachypodium sylvaticum, Des-champsia
cespitosa and a rich variety of herbs including Actaea spicata and
Ophrys insectifera. The lower 15 m of the valley are occupied by
fragments of alderwood and more extensive Juncus-Carex calcareous
marsh and wet grassland, with an unusual number of rare and local
species, notably Primula farinosa, Trollius europaeus, Epipactis
palustris, Schoenus nigricans and Carex aquatilis. Adjacent to the
mixed deciduous woodland is limestone grassland with numerous herb
species (e.g. Cirsium eriophorum) showing invasion by hawthorn. The
whole forms an important woodland-grassland-mire complex of great
floristic interest.

W.I43- CONISTONE
OLD PASTURE AND BASTOW WOOD, YORKSHIRE
SD 9867.
380 ha
Grade i
The site occupies part
of the Carboniferous Limestone escarpment on
the eastern side of upper Wharfedale. Great Scar limestone, divided
into two main blocks by a narrow gorge, outcrops as pavement, scar
and associated scree. Much of the soil is thin humus-carbonate
occurring in patches on the exposed limestone, but on the valley
sides and in depressions a deeper clay has developed, and in some
places acid, sandy loam. The more southerly of the blocks is wooded;
closed woodland mainly of ash, wych elm, and hazel with calcicolous
shrubs such as privet, buckthorn, and whitebeam, considerably
invaded by sycamore, characterises Grass Wood, while in the
contiguous Bastow Wood birch is predominant over much of the area
and forms an open canopy. This difference is probably related to
site history, in addition to somewhat greater elevation, for Bastow
Wood overlies a Celtic field system, and the contrast is now being
accentuated by re- forestation of Grass Wood, mostly on a shelter
wood system, but locally by clear felling and replanting with
conifers. Dib Scar, descending steeply into the gorge drained by Dib
Beck, forms the northern limit of this block, beyond which rises the
complementary limestone grassland and pavement of Conistone Old
Pasture, characterised by typical close-cropped species- rich swards
and a grike flora. Ecologically this site belongs partly with the
lowland calcareous grasslands, and gives an interesting comparison
with the more distinctly montane limestone communities in Cowside
valley and the higher slopes of Malham-Arncliffe (U.24).
The main feature of interest
is the herbaceous flora which is
outstandingly rich. The woods of the area are known as a locality
for the very rare Cypripedium calceolus, which has been reduced
almost to extinction by plant collectors. Herbs still present
include Polemonium caeruleum, Thalictmm minus, Geranium sanguineum,
Polygonatum odoratum, Paris quadrifolia, and Origanum vulgare. More
open ground in the area has Draba incana, Arabis hirsuta, Polygala
amara, Saxifraga hypnoides, and Sedum telephium, while flushes and
damper pastures have an abundance of Primula farinosa and Parnassia
palustris. The afforestation programme may ultimately reduce the
variety to some extent, but most species and the general richness of
the habitat are expected to survive.

dominants. Other abundant species include Primula vulgaris, Fragaria
vesca, Potentilla sterilis, Viola riviniana, Prunella vulgaris,
Circaea lutetiana and, more locally, Paris quadrifolia and
Convattaria majalis. This wood is evidently only lightly grazed, and
is probably the best remaining limestone wood of the Wharfedale
area, the rest having been ecologically degraded in recent years by
felling or sheep-grazing.

12 ha
Grade 2
These woods are on Carboniferous
Limestone of the Yore-dale Series
in steep gorges associated with the west-east-flowing River Swale
and its small north-south-flowing tributary, East Gill, near Keld.
While forming an ecological unit, they are physically separated by a
field in the angle of the junction of the rivers. The altitude is
270-350 m, so that the woods have a submontane character.
The woods are dominated
by ash, particularly fine specimens
occurring on the south side of the Swale. Birch is important as a
constituent of the canopy toward the upper woodland edges whilst
wych elm is locally abundant near the rivers and alder follows some
small side streams on the south side of the Swale. Hawthorn, bird-
cherry, blackthorn, and rowan are present as understorey or shrubs;
hazel occurs, and is particularly well developed on some relatively
open and more level ground south of the Swale. Though variable, the
average height of the tree canopy is about 8 m.
The ground flora varies
according to the substrata which range from
limestone to acidic sandstone and, alongside East Gill, to base-rich
alluvium, but in general reflects only moderately base-rich
conditions. A disused lead mine tip with Minuartia verna forms a
scree, cutting through the wood on the north side of the Swale. The
range of forbs includes such species as Brachypodium sylvaticum, Mer-
curialis perennis, Allium ursinum, Primula vulgaris, Sanicula
europaea, Filipendula ulmaria and Viola spp. In East Gill, Campanula
latifolia and Cirsium heterophyllum also occur at lower levels and
the woodland ground flora gives way to a small piece of attractive,
wet, calcicolous meadow flora between wood and river. Ferns, notably
Athyrium filix-femina, are prominent on the south side of the Swale
among the bigger trees. A range of bryophyte communities is also
represented.

These sites are regarded
as fragments of a once more extensive
subalpine ashwood covering much of the lower slopes of the Craven
Pennines and have survived by virtue of physical features; a
limestone pavement in the case of Colt Park and a steep-sided ravine
at Ling Gill, both of which afford protection from grazing. Both
woods are on Carboniferous Limestone; Colt Park is developed over a
pavement of limestone at about 340 m whilst Ling Gill is cut into
the upper part of the Great Scar limestone, at a similar elevation,
3 km to the north-east.
The tree layer in both
woodlands is composed mainly of rather open
and somewhat stunted ash. In Ling Gill the ash tends to be more
abundant on the crags and gill sides. In both woodlands a shrub
layer is present and contains hazel, hawthorn, bird-cherry and
rowan. Wych elm, birch and (in Ling Gill) aspen are also to be found
scattered throughout the canopy in places. Both areas have a rich
flora as a result of the calcareous substratum and lack of grazing.
Tall-herb communities are well developed and contain Trollius
europaeus, Geranium sylvaticum, Cirsium heterophyllum, Actaea
spicata, Crepis paludosa, C. mollis, Geum rivale, Angelica
sylvestris, Campanula latifolia and Paris quadrifolia. Gagea lutea
is less frequent. Submontane plants include Potentilla crantzii,
Galium boreale and Asplenium viride. In Ling Gill podsolic soils
above the rocky ravine slopes have an acidiphilous field layer with
Pteridium aquilinum, Molinia caerulea, Potentilla erecta and Galium
hercynicum.
The moist atmosphere and
shade of Ling Gill ravine and the grikes at
Colt Park have led to the occurrence of a rich bryophyte flora on
the limestone.

These woods occupy the
rocky gorge of the River Tees cut through the
Carboniferous Series, 6.4 km above Barnard Castle. The lower parts
of the wood are high forest of wych elm, ash, pedunculate oak and
alder, with yew, hazel, holly, rowan and bird- cherry locally. There
is a wide range of age classes, but some of the elm has been
coppiced or pollarded. At the southern end where the wood was once
cut-over, birch, hawthorn and willow dominate. These woods are on
limestone, but the upper levels over acidic rocks are dominated by
oak and birch. The ground flora of the lower levels is particularly
rich with abundant Myosotis sylvatica, Geranium sylvaticum, Geum
rivale, Paris quadrifolia, Chrysosplenium spp., Allium ursinum,
Luzula sylvatica and numerous ferns. The bryophyte flora is quite
rich, both in calcicolous elements on the damp boulders lower down,
and in calcifuge species on the acid loamy soil and rocks higher up.
The wood is, however, outstanding for its flora of epiphytic
lichens, which includes the relict forest species Lobaria
pulmonaria, L. laetevirens and Baccidia affinis: this is the first
definite British record of the last-named lichen.

the field layer is very rich. A wide range of mesophilous and
calcicolous species is represented and includes Actaea spicata,
Paris quadrifolia, Sesleria caerulea, Cirsium heterophyllum and

Grade 2
These two valleys north
of Ingleton lie at 120-200 m on strongly
contrasting rock types, namely Carboniferous Limestone which is
confined to the western glen, and Silurian slate in the eastern and
part of the western glen. The limestone woodland has pedunculate
oak, wych elm, ash mixtures with a range of age classes, but over
the slates sessile oak is dominant, with rowan, birch and, beside
the stream, small-leaved lime. Though the vascular flora reflects
the strong contrast in underlying lithology and is rich in
aggregate, the site is more important for its outstanding bryophyte
and lichen floras. The bryophytes include many species of calcareous
habitats, but also a number of moisture-loving oceanic species
surviving in an area of relatively low rainfall and calcareous
rocks. After the Lodore Falls in the Borrowdale Woods (W.I33), this
is probably the best locality in northern England for Atlantic
liverworts characteristic of damp, waterfall glens at low
elevations. Some of these species are unknown elsewhere in the
Pennines, for they avoid limestone. The site owes this bryological
richness, unusual also in an area of relatively low rainfall, to its
western position, the presence of relatively acidic rocks and the
