Klämmeshöjden, Naturreservat

The nature reserve was established to preserve biodiversity and valuable natural environments such as the area's species-rich natural forests with their ecosystems and biodiversity.

Most of the forest area consists of spruce in the lowlands and leaner pine forest, often with elements of rocks, on the heights. In the western part, there is hyperite in the bedrock, which has given a herb-rich flora and valuable soil fungal flora. The eastern part of the reserve consists of wetlands with very high values, especially high bird values.

Animals and plants

The area has great botanical value as it is home to a number of red-listed cryptogams (e.g. lichens, mosses and fungi) whose habitat requirements are found in natural forests with large amounts of dead wood. For example, there are great values associated with the limestone coniferous forest at and near Klämmeshöjden, where the endangered fungus bomb marble grows. Species such as the four-lobed earth star, wood bustard, green shield moss, violet-grey thorn lichen, brown-powdered needle lichen, hull lichen and dwarf beak lichen are other examples of red-listed species found in the area, several of which are linked to different types of dead wood.

Klämmeshöjden also has great zoological value due to the special conditions of the old-growth forest as a habitat for bird fauna and wood-living insects. The red-listed three-toed woodpecker and the wood grouse capercaillie and wolverine are found here. In addition to these red-listed species, there are a large number of 'signal species', i.e. species whose presence indicates high forest natural values. Some of these signal species are the wood-boring beetle, the vascular plants spiderwort and eyebright, the fungi flesh tick and tickmussel, the lichens spruce bark lichen and shade lichen, and the mosses stump moss and edge moss.
