The River Moy Special Area of Conservation is a vital freshwater habitat in western Ireland, known for its rich biodiversity and outstanding angling opportunities.
The River Moy Special Area of Conservation (SAC) encompasses a significant stretch of the Moy River and its tributaries in County Mayo, western Ireland. This protected area is renowned for its ecological importance, providing habitat for several important aquatic and riparian species, including the Atlantic salmon (Salmo salar), otters (Lutra lutra), and freshwater pearl mussels (Margaritifera margaritifera). The river’s clean, fast-flowing waters and diverse substrates create ideal conditions for spawning salmon and other native fish species, which support a world-class fishing culture along its banks.
Geographically, the SAC stretches from the river’s source in the Ox Mountains, flowing approximately 110 km before entering the Atlantic Ocean at Killala Bay. The surrounding landscape consists of upland areas, farmland, and wetlands that contribute to the ecological connectivity of the area. Rich in both cultural heritage and natural beauty, the river has long been an economic and recreational resource for local communities.
Visitors are drawn to the River Moy SAC primarily for angling, particularly salmon and trout fishing, which has been practiced here for centuries. Additionally, the river and its environs offer opportunities for birdwatching, hiking along adjacent riverbank trails, and wildlife viewing. The area is part of Ireland’s Natura 2000 network, underscoring its conservation value and the collaborative efforts to maintain its pristine quality. Visitors appreciate the unspoiled rural character and the peaceful experience of Irish countryside recreation.
The SAC's careful management balances conservation needs with sustainable outdoor use, safeguarding critical habitats while supporting traditional activities like angling and low-impact tourism. Significantly, the region’s natural resources contribute not only to biodiversity preservation but also to the local economy through eco-tourism and cultural heritage linked to the Moy River’s legacy.
