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 selection for any eligible native fish species in Great Britain that inhabit freshwater systems for all or part of their life cycle, including migratory species that spend part of their life cycle at sea (i.e. diadromous species). Those species that use rivers, estuaries and marine environments must have free movement between them if they are to complete their life cycles. Linked and contiguous notifications for river and estuarine habitat, including the river’s saline transition zone, are therefore the best means of protecting the full range of characteristic fish assemblages. This guidance covers the same habitats as SSSI Selection Guidelines for Freshwater habitats and aligns with the guidance in that chapter.
