Crayfish populations in Cavan and Monaghan are under increased threat from “crayfish plague”.
This week, the National Parks and Wildlife Services issued a “severe and increasing” threat to native species. The spread of the plague and introduction of non-native crayfish species has threatened the wipe-out of the endangered species.
Non-native, invasive crayfish have been banned in Ireland in an attempt to protect the native species. Last year, a number of dead crayfish were found in rivers across Cavan and Monaghan, with “crayfish plague” believed to be the cause.
