The well-documented decline of native white clawed crayfish (Austropotamobius pallipes) in mid-Wales has been well documented in the upper catchments of the Wye and Usk Rivers. Causes of the decline have been identified as plague, silt and synthetic pyrethroids and all now have control measures in place. Some populations seem to have begun to recover but concern over the plight of the species have stimulate wider surveys revealing previously unknown very viable populations.
