Guidelines for the Selection of biological SSSIs

Part 2: Detailed guidelines for habitats and species groups

The statutory nature conservation agencies have a duty under the Wildlife and Countryside Act 1981, as amended, to notify any area of land which in their opinion is 'of special interest by reason of any of its flora, fauna, or geological or physiographical features'. Such areas are known as Sites of Special Scientific Interest (SSSIs).

This Chapter covers mammal species, excluding seals. Site selection for species and assemblages should be based on stable populations, however, as many threatened species are experiencing severe declines this approach should be used as a guideline only and there may be justification for the selection of species and assemblages in unfavourable condition.

Note that the section on seals has not yet been revised, and is available as a separate document.
