Komosse is one of the most valuable peat bog complexes in north-western Europe. It contains large and representative examples of natural boreal wetlands: raised bogs, open peatland, bog woodland, wet meadows and fens. The boundaries of the Site have been adjusted to match those of the Nature Reserves, leading to an increase of around 200 hectares. Unusually for this part of the country, a large pool system is located in the bog complex. The Site has been largely unaffected by human activities, which contributes to the maintenance of water quality downstream. Komosse is important for plant species dependent on open areas of nutrient-poor bog landscapes, as well as for migrating and nesting birds including the nationally endangered ruff Philomachus pugnax. The wetland is one of the most researched peat bogs in Sweden. The main threats affecting the ecological character of the Site relate to drainage, and habitat shifting and alteration. As part of the EU LIFE “Life to ad(d)mire” project, measures have been taken to restore 40 hectares of land affected by ditches for forestry purposes and to regenerate wet meadows and bog woodland in the south-eastern part of the Site. The project also entailed the clearance of about 40 hectares of raised bog which had been invaded by Pinus shrubs, in order to increase suitable nesting ground for wading birds.
