An archipelago, about 20 km from the mainland. The largest island, Heimøya, is 1 km long. Two of the islands are connected with a mole. The largest islands are covered with heathland Empetrum/Calluna, mixed with bushes Rubus/Cornus. Fishermen lived on Sklinna up to the first half of this century, but now the only settlement is the lighthouse (manned year-round) on Heimøy.
The breeding colony of Phalacrocorax aristotelis is one of the largest in Norway.
Pressure/threats to key biodiversity
The breeding seabirds at Sklinna are monitored annually by the Norwegian Institute for Nature Research as part of the National Monitoring Program for Seabirds, and the area is a proposed Nature Reserve. American mink Mustela vison, has not been able to reach the archipelago because it is situated so far from the mainland, which is an advantage for the breeding seabirds.
