Other Site Characteristics

This site consists entirely of mixed forest, most of it is dominated by conifers. It is however a very patchy landscape according to moist and soils. Approximately one third of the site is flat-rock pine forest on outcrop of Precambrian bedrock and one third is bog woodland, with mixed forest of spruce, pine, alder and birch. The peat-layer is usually thin, and some of the wet forests have no peat at all. The rest is mixed forest on till, dominated by spruce, with a lot of aspen. Aspen also occurs frequently along borders of the many small patches of flat-rock pine forest.

4.2 Quality and importance

Much of the quality of this site consists of being a part of a local network of small mixed forests in near natural conditions, situated nearby each other. This site is more typical western taiga than neighbouring sites according to tree-species. There is very little of southern broad-leafed deciduous trees like oak, ash, lime and maple. This might be due to less cultural influence long time ago. Another possible explanation might be less lime-rich soils as the flora is more normal coniferous forest-type with few herbs. Important qualities of the site are the very few signs of human activity, trees of varying ages and species as well as a lot of dead lignum. The many natural glades of bedrock outcrop continuously support richness in aspen. In boreal forests aspen usually is dependent on long-term fire dynamics or clear-cutting. However, up to the 1980-ies aspen was usually removed when thinning in forests with normal intensive forestry. At that time forestry started to leave aspen when clear-cutting due to consideration on nature conservation interests. On aspen in this site there is an interesting flora of epiphytic lichens. The many glades probably also support a rich fauna of insects inhabiting dead lignum. Most of these species prefer light and warm habitats.
