1029 Freshwater pearl mussel Margaritifera margaritifera
The Cladagh (Swanlinbar) River rises on Cuilcagh Mountain and flows through County Cavan in the Republic of Ireland before crossing the border into County Fermanagh in Northern Ireland, and eventually entering Upper Lough Erne. It is a moderately large river, being ultra-oligotrophic in its upland reaches within the Republic of Ireland, before gradually becoming oligotrophic and oligo-mesotrophic through its middle and lower reaches within Northern Ireland. The freshwater pearl mussel Margaritifera margaritifera population, which is estimated to have a minimum number of 10,000 individuals, is confined to 6 km of undisturbed river channel in the middle section of the river. It is one of the largest known populations surviving in Northern Ireland.
