Wilderness Landscape & Natural Heritage
Lough Mask Special Area of Conservation (SAC) is located in County Mayo, Ireland, encompassing the expansive freshwater Lough Mask and its immediate environs. Covering approximately 83 square kilometers, the area is renowned for its ecological importance, supporting a variety of habitats such as oligotrophic lakes, natural eutrophic lakes, and alluvial forests. The lake itself is one of the largest in Ireland and supports a diverse range of aquatic species including native brown trout, Arctic char, and freshwater pearl mussels, a critically endangered species. The surrounding landscape features limestone pavement and upland areas, which provide habitats for rare flora and fauna, making the SAC a vital refuge for biodiversity conservation in the west of Ireland. Historically, Lough Mask has been a hub for local communities and outdoor enthusiasts, with angling attracting visitors worldwide. Recreational opportunities include fishing, boating, birdwatching, and hiking along scenic shoreline trails. Notable landmarks include the ancient crannogs (lake dwellings) visible on the lake and the nearby charming lakeside villages such as Cong. The area's tranquil natural beauty, combined with cultural heritage, makes it a captivating destination for eco-tourism and outdoor recreation. Management of the SAC focuses on protecting water quality and habitats while promoting sustainable recreation.
