Other Site Characteristics

The site consists mainly of the northern part of one of the bigger islands in southern Stockholm archipelago. It also includes some surrounding small islands and several thousand hectares of sea. Important marine habitats occur mainly along the eastern shore of the island, where vast shallow areas with sandy sediments and lots of small islands are situated. A minor part of this area is included in the site, whereas most of it is part of a military artillery range. The bedrock is varying with e.g. iron ore, Precambrian limestone and many rare minerals. Mining started probably already in the 12th century. The mining had its maximum in the 18th to 19th centuries. It ceased in late 19th century. During the most intense period of mining the forests of the island was nearly entirely clear-cut. Interesting terrestrial habitats is mainly occurring on outcrop of limestone bedrock, which occur patch-wise on the main island and on some of the islets.

4.2 Quality and importance

Precambrian limestone have scattered occurrences in southern part of Stockholm archipelago. Here there are more of non-forested bedrock outcrop than in inland occurrences. A special vascular plant-, bryophyte- and lichen-flora occurs in this habitat. It has much in common with some types of the alvar-vegetation common on the Baltic islands Öland, Gotland, Saaremaa, Hiumaa and along the Estonian north-west continental coast. There are also flora-elements from calcareous areas of the Scandian alpine vegetation. Also the invertebrate-fauna have many interesting components. Attention have especially been paid to land-snail- and butterfly-faunas of this habitat. From this site is known e. g. the bryophyte Tortella rigens and the land snail Vertigio angustior. Tortella rigens is, as far as known, restricted to calcareous rock around the Baltic coasts in Sweden and Estonia. The marine habitats are little known except for breeding birds. However, the last available inventory was made about twenty years ago and since then much might have changed. The part of the flad-system included in the site was rich in breeding marine birds, but mainly common species. More species-rich fauna with some, in the region, rare species was found in the artillery range. Characea-vegetation have been observed on shallow bottoms both inside and outside the site. Several red data list species have recently been found outside the site. No investigation on species-level have been carried out within the site. The figure after the species in the Sweden species-table indicates the category in the national red data list.
