Definition of Favourable Conservation Status for White-clawed crayfish (RP2933)

This document sets out Natural England’s view on Favourable Conservation Status (FCS) for White-clawed crayfish Austropotamobius pallipes in England. FCS is defined in terms of three parameters: natural range and distribution; population; extent and quality of habitat necessary for long-term maintenance of populations.
This section provides the summary definition of FCS in England. Section 2 provides contextual information, section 3 the metrics to be used whilst section 4 describes the evidence considered when defining FCS for each of the three parameters. Section 5 sets out the conclusions on favourable values for each of the three parameters. Annex 1 lists the references.
This document does not include any action planning, or describe actions, to achieve or maintain FCS. These will be presented separately, for example within strategy documents.
