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 a range of coastal habitat types, such as saltmarshes, sand dunes, machair, vegetated shingle, and maritime cliff and slopes. These guidelines provide the basis for selection of SSSIs for these coastal habitat features.
