Wilderness Landscape & Natural Heritage
Lough Derg SAC (Special Area of Conservation) encompasses the Irish portion of Lough Derg, a large and deep freshwater lake situated on the River Shannon, Ireland’s longest river. Spanning counties Clare, Tipperary, and Galway, this SAC designation protects the lake’s challenging aquatic ecosystem characterized by high water quality and diverse habitats. The site includes significant areas of submerged aquatic vegetation, which support rare and endangered species such as freshwater pearl mussel (Margaritifera margaritifera), otters (Lutra lutra), and various fish species including Atlantic salmon (Salmo salar). The surrounding shoreline also supports important wetland habitats, reedbeds, and some terrestrial woodland fragments that are critical for bird species such as the Greenland white-fronted goose and little grebe. Historically, Lough Derg has been important for local fisheries and recreation, including boating and angling, which continue today. Visitors can enjoy kayaking, bird watching, and walking routes along the lough’s shores and adjoining areas. The SAC’s outstanding natural heritage values make it a key conservation site in Ireland’s network of protected freshwater habitats. Its often tranquil waters and scenic vistas attract nature lovers and anglers alike, providing both biodiversity protection and opportunities for sustainable outdoor recreation. Conservation efforts focus on maintaining water quality, preventing invasive species spread, and protecting sensitive habitats from development and pollution pressures.
