The Site includes a system of intertidal shallow waters including a sheltered bay (Mellandsvågen) and mussel and seaweed beds; extensive mudflats; salt marshes, wet meadows and mires; and rocky outcrops bordering a 1,000-hectare wildlife protection area. The Site’s location makes it important for migrating birds, in particular geese, ducks and waders that feed, rest, moult or winter there. From autumn until spring migrations the area is important for species such as red-breasted merganser (Mergus serrator), velvet scoter (Melanitta fusca), common eider (Somateria mollissima) and long-tailed duck (Clangula hyemalis), at times in high numbers. Species such as greylag goose (Anser anser), common redshank (Tringa tetanus), Eurasian oystercatcher (Haematopus ostralegus) and mew gull (Larus canus) appear to breed regularly within the Site. Human activities include recreational activities, birdwatching and fishing. Run-off from neighbouring farmland may affect the Site, while boat traffic could affect the bird life, especially during spring.
