This Site is an exceptional area of lowland blanket bog, which includes a rich diversity of habitats and landscape features including mountains, exposed rock and scree, blanket bogs, dry, wet and alpine heath, upland grassland, wet grassland, rivers, lakes, scrub and woodland. Its rivers and lakes connect the site to the Gweebarra River and Gweebarra Bay. These habitats support breeding golden plover (Pluvialis apricaria) and red grouse (Lagopus lagopus scotica), and foraging merlin (Falco columbarius), peregrine falcon (Falco peregrinus) and golden eagle (Aquila chrysaetos). Otters are present and are likely to use the lakes, river and streams for foraging. The Site is used for recreation and supports nutrient cycling, soil formation and pollination. Rhododendron ponticum is present within the National Park in which the Site is found, which threatens adjacent blanket bog and woodland as it can seed into and spread within these habitats.
