Crayfish population in Cavan and Monaghan under “increased threat”

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.
