Status
Conservation status
Ireland: Near Threatened
EU: Least Concern
There are historic records from sites through the Irish midlands and in the south and east, but it was lost from most of these before the mid 1980s. Due to evidence of decline in the east prior to 2000 and the poor current status and future prospects for turloughs, the species is evaluated as Near Threatened.
