The Site is a wetland system consisting of four subsites: Selvikvågen, Lomstjønna, Malesanden og Huse and Lyngholman. Habitat types include shallow bays, extensive tidal, mud and sandflats with seaweed zones, sand dune systems, mires, and freshwater and salt marshes. Large quantities of seaweed accumulate, creating rich feeding areas for large numbers of breeding, migrating and wintering bird species. The Site also offers habitat to the threatened otter Lutra lutra, harbour seal Phoca vitulina, and several nationally threatened plant species. The rocky shores are important for shoreline stabilization. Threats to the Site include changes in agricultural practices and related overgrowth of bird habitats. Human activities include nature conservation, fishing, livestock grazing, birdwatching and other recreational activities. There is a birdwatching tower and information booklets are available.
