SSSI Guidelines - Chapter 6 - Freshwater Habitats 2018


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 freshwater habitats, from springs, seepages and upland torrents to sluggish slow-flowing rivers, and from cold deep lakes to temporary pools. They support a rich array of biological assemblages, which contain many rare or threatened fish, invertebrates, plants and other species. These guidelines provide the basis for selection of SSSIs for these freshwater habitat features.
