4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

The reserve consists of 21 islands, ranging in size from 0.5 to 13 ha, and the surrounding waters. The reserve which is 25 km long runs west-east and is situated in Kalix's outer archipelago. Most of the islands consist of till materials, though shingle stone fields and exposed bedrock landscapes occur. The tree canopy is either sparse or lacking on all islands. However many of them have a rich vascular plant flora and many provide important bird habitat. Only two of the islands have buildings on them, one island has one summer cottage and another has two summer cottages. Innerstgrundet (2.3 ha) and Mittigrundet (2.1 ha) have scattered thickets of pine, birch and mountain ash. Terns and gulls nest on the islands. Västra Gräddmanhällan (1.7 ha) and ÖstraGräddmanhällorna (1 ha) which are slab bedrock islands are interesting from a geological perspective. The bedrock is made up of dolomitic limestone, which gives rise to a lush and interesting flora, which includes the most Sweden's most easterly population of Carex capitata. Another very interesting feature is the presence of stromatolites, fossilised algae. The islands Slätbådan (5 ha), Stenen (10 ha), Stengrund (2.8 ha) and Tjärugrundet (1.8 ha) are characterised by a band of the eye-catching Lythrum salicaria along the shore line. The island of Kusen, which is a former bird reserve, differs from the other islands in that it is built up of sand. The many years of protection has allowed a rich and varying bird fauna to develop. A rich flora has also developed, helped by the large amount of goose manure. The island Lutskkärsgrynnan (3 ha) which is in the middle of the reserve supports a rich bird fauna with among others the waders Arenaria interpres and Tringa totanus. Halsögrundet which is the largest island (13.1 ha), is a nesting island for skua, Stercorarius parastitcus. This bird is a real rarity in Norrbotten's archipelago.

4.2 Quality and importance

There is little human disturbance and the islands are an important refugium for the archipelago's flora and fauna. The vegetation is influenced by the brackish water environment and the ongoing land upheaval which results in a succession of different vegetation types. These land upheaval pioneer vegetation communities, which are also exposed to harsh (windy and dry) climate, are unique from an ecological perspective. Several of the islands support a rich avian fauna. The islands are also interesting from a geomorphologic perspective as there are many examples of how upheaval landforms are affected by wind and wave action.
