The Site is a large mire complex dominated by flat fens, which also includes pools, ponds and parts of the Atnsjøen lake. A characteristic of the Site is its nutrient-poor vegetation, though willow and birch forests are common along the watercourses and mire edges. The mixture of different wetland types makes the Site a valuable breeding area for ducks such as tufted duck (Aythya fuligula) and common goldeneye (Bucephala clangula) and waders such as common sandpiper (Actitis hypoleucos) and common greenshank (Tringa nebularia). The Site also host nationally threatened species, such as the greater scaup (Aythya marila), the black-headed gull (Chroicocephalus ridibundus), black-tailed godwit (Limosa limosa), velvet scoter (Melanitta fusca), horned grebe (Podiceps auritus), and northern lapwing (Vanellus vanellus). Some threatened plant species can be found, such as the ghost orchid (Epipogium aphyllum) and the cotton grass (Eriophorum brachyantherum). The mires are important water reservoirs and offer flood protection during periods of snow melt and heavy precipitation. The Site is used for hunting, sports fishing, berry picking and sheep grazing. Restoration of the Site is planned: trenches dug for agriculture and peat harvesting will be filled, and dams will be built to increase water retention.
