Modell för ett integrerat skärgårdsskogsbruk : en fallstudie på Kallsö

Abstract: The forests in the unique archipelago of the Baltic Sea is housing many and high values. For the resident population, which has a central role in sustaining a living archipelago, the forest can contribute to the outcome. The forest also contributes to turn the archipelago into one of Sweden's most attractive recreational areas. Furthermore, these forests exhibit very high environmental values, and they are an element in the traditional cultural landscape. This work suggests a silviculture in the archipelago where environmental-, cultural-, recreational-, and economical values are integrated. With Kallsö, in the archipelago of S:t Anna, as example, seven habitats were identified as particularly important to distinguish when managing forests in the archipelago of Östergötland. The forest in the archipelago can be divided accordingly to these habitats into the following management classes: Typical rocky grounds high up in the terrain Periodically, very dry sites with shallow soil where almost exclusively pine is growing. The stands contain a great share of impediment. Only cautious selective cuttings are recommended. Slopes and moraine grounds of medium heights The largest management class and thereby also the most important for forestry on Kallsö. However, the silviculture must be flexible since the terrain is varying. Leaving shelterwoods and seedtrees, and gap-cuttings can be carried out in combination. Valley bottoms and sediment grounds Fertile sites, which often has been used for agriculture. If the location is not too exposed clearcutting can be used. The stands should be managed to maximise the volume production. Yet, some parts should be set aside for environmental consideration. Forests along shores Larger sites with the character of shore-forest, which often have long continuity. The stands are often dense and dominated by broadleaves. Should be set aside for environmental consideration. Small islands Minor forested islands that are suitable to set aside for environmental- and recreational values, either for free development or tending with focus on conservation. Sites dominated with alder Larger sites with alder by the sea, or alder swamps further up on the islands. These should be set aside for their highly environmental values. Oak dominated sites with character of pastureland Very important sites for the environment in the archipelago, which also have an aesthetic value in the scenery. Should be tended and grazed to accomplish a continuous oak succession. The outcome of the suggested management has been compiled and indicates that there are potential for forestry in the archipelago. But it has to be carried out with great caution and consideration to other interests. The conclusion is that a small-scaled and well adapted forestry is most advisable in the archipelago, and that there are several advantages in choosing silviculture methods that implies that the land always is more or less forested.
