The Site in the county of Nordland consists of the southernmost area of Verøy Island. The western part of the Site is a steep area rising from the sea up to a mountain plateau at an altitude of 400 metres; it is covered by rich vegetation due to the nutrients brought by the large colonies of seabirds. The Site also contains a characteristic system of sand dunes with unique botanical values. It is one of the large bird mountains along the Norwegian coast and has a high value as a breeding site for several bird species. The bird cliffs are important breeding sites for the vulnerable Atlantic puffin (Fratercula arctica) and the black-legged kittiwake (Rissa tridactyla). The harbour seal (Phoca vitulina) and European otter (Lutra lutra) occasionally visit. Collection of eggs and down from some species is permitted within the protected landscape area comprising the eastern part of the Site but forbidden within the nature reserve in the western part. Bird cliffs are important in the nutrient flow between the ocean and land, as the birds foraging in the ocean spread guano across the cliffs and surrounding area. The Site is also important for tourism. Reductions in the stocks of some fish species because of natural fluctuations, overfishing and climate change have had an impact on the breeding success of the seabirds. Petrol pollution poses a threat to the feeding of bird species in the Site.
