• Surveillance of annual status of marsh

2.
Manage the
vegetation by a controlled grazing programme by scheduling the
following projects
• Grazing programme and records - management
of stock and grazing levels to maintain the appropriate vegetation
structure.
Prescription 3. Provide shelter for egg-laying
adults Projects:
• Manage shelter belts and hedges -
establishment and maintenance of a system of shelter belts and
hedges around all field boundaries.
Objectives for
the marshy grassland and neutral grassland made no reference to
marsh fritillary, and there was, therefore, a very poor connection
in the plan between the species and the management of its
habitat.
