The Site comprises three rich and productive sub-sites, Hammervatnet, Lundselvoset and Lyngås-Lysgård, featuring shallow freshwater areas, inland deltas and lakes. It is important habitat and feeding area for the European otter (Lutra lutra) and European eel (Anguilla Anguilla). During spring and autumn migrations several thousand pink-footed geese (Anser brachyrhynchus) stop at Lyngås-Lysgård and Lundselvoset. Leksdalsvatnet is a breeding site for the globally vulnerable horned grebe (Podiceps auratus). The main activities within the site are cattle grazing, fishing and birdwatching tourism. There is eutrophication of freshwater lakes caused by agricultural activities. Some restoration including the dredging of accumulated biomass has been undertaken. Mappings of the bird life were carried out in 2018, 2020 and 2022.
