The information in
this section has been taken from 'A Nature Conservation
Review' a 2-volume work by Derek Ratcliff,
published by Cambridge University Press in 1977. It set out to
identify the most important places for nature conservation in Great
Britain. It is often known by the acronym NCR, and sites listed in
it are termed "NCR sites".
Volume 1 set out the
rationale and methods used, and gave descriptions of the major
habitat types.
Volume 2 consisted
entirely of a site inventory. Sites were grouped into six major
habitat types:
-
Coastal sites - 135
sites
-
Woodlands - 234
sites
-
Lowland grasslands, heaths and scrub -
159 sites
-
Open waters - 99
sites
-
Peatlands - 116
sites
-
Upland grasslands and heaths - 101
sites
