Assessment of the condition of the white-clawed crayfish Austropotamobius pallipes in the River Wye Special Area of Conservation (SAC) (2014).
In October and November 2014, parts of the River Wye Special Area of Conservation (SAC) on the Afon Edw, Nant yr Offeiriad and Sgithwen Brook were surveyed for white-clawed crayfish to assess the condition of both the crayfish populations and crayfish habitat. The work was undertaken to provide some of the data required to assess whether the white-clawed crayfish in the River Wye SAC was in favourable condition. Whilst further data will need to be collected before the full assessment can be made, the apparent lack of white-clawed crayfish in the Afon Edw, following a mortality in 2006, is worrying given that this has been a very important waterway for this species in the recent past. Whilst crayfish numbers were relatively robust in Nant yr Offeiriad and Sgithwen Brook, populations were mostly confined to the headwaters. It is important to complete survey work for white-clawed crayfish on the River Wye SAC in 2015 so that the 2014 results can be amalgamated into an overall assessment.
