The Site is a complex of eight separate areas along the north-western coast of Norway, comprising numerous skerries and islets and a larger island, with shallow marine waters, rocky shores, and some sandy beaches. Its wet meadows, dunes and dune slacks, as well as brackish marshes, are typical of the biogeographic region. The Site is a breeding area for a number of seabird species, the white-tailed eagle Haliaeetus albicilla (with 10-15 pairs recorded), and the harbour porpoise Phoca vitulina. It is also a wintering area for the great northern diver Gavia immer and the yellow-billed loon Gavia adamsii. The Site is used for recreational activities, fishing and sheep grazing. Traditionally the breeding population of common eiders were exploited for down and egg collection, which contributed to a high population of species as they benefited from predator protection and erection of breeding-houses. The abandonment of some such traditional practices threatens the ecological character of the Site, but there are plans to revive them. Heather and juniper burning as well as grazing are practised to prevent overgrowing. The Site was extended in 2012.
