Krunnit Islands. 28/05/74; Oulu; 4,435 ha; 65°23'N 024°47'E. Natura 2000 SPA, SCI. Four disjunct island groups with several large forested islands and 15 small morainic islands forming a unique and virgin series of island land upheaval succession. The northern part of Ulkokrunni Island is crossed by a low esker formation with heath-like vegetation. The area includes about 20 small islands or islets which are either grassy, sandy or bare and rocky skerries. Because of strong land upheaval, the shores are in a continuous stage of succession. The sites host three listed vascular plants species: Hippuris tetraphylla, primrose Primula nutans, and water-plantain Alisma wahlenbergi. Amongst the threatened bird species are Little Tern, Caspian Tern, Temminck's Stint and Black-headed Gull. Breeding bird populations are the most valuable in the Bothnian Bay archipelago, and the site is one of the most important summer-molting areas of Greylag Goose and Goosanders. Runaways of fur-farmed Arctic Foxes cause occasional damage to the breeding of birds.The site, where landing is prohibited in the breeding season of birds, has been a private protected area since 1936 and an important education site for the University of Oulu. Ramsar site no. 7. Most recent RIS information: 2005.
