Abstract

The survival of Austropotamobius pallipes in Britain is threatened by habitat modification, pollution, exotic crayfish species, and crayfish plague. The status of A. pallipes in the catchments of the relatively unpolluted Upper Wye and Upper Severn were surveyed in July~August 1988. Sixty-two sites were visited and A. paUipes was found at 48% of them. The Llynfi and Teme sub-catchments were particularly well populated A large number of environmental variables was measured at each site and multiple regression techniques used to determine which of the variables most influenced crayfish abundance. It was concluded that, provided the water chemistry ensured crayfish survival the size of the crayfish populations was determined principally by the steepness of the channel banks, the presence of riparian shrubs and trees, and the extension of their roots into the water. The channel margins seemed to be especially important as nursery areas for the young crayfish. It is essential where A. pallipes is to be protected or re-established, that these bankside features are retained, enhanced or restored.
