Deadwood in Nuuksio National Park

Deadwood is a rarity in Finnish forests. It is actually only found in the national park, as in industrially used forests the wood is almost completely removed from the forest and used when it is cleared for the paper and construction industries.In ecology and in particular in biotope and species protection, deadwood is used as a collective term for dead trees or parts thereof. A rough distinction is made between standing deadwood, i.e. dead trees or parts thereof that have not yet fallen over, and lying deadwood that is already lying on the ground.The term deadwood is used here in a broader sense; as biotope wood it also includes (small-scale) damaged, sick or dying trees, bushes and parts thereof: Standing deadwood is rarer, but usually offers a greater variety of site factors and is therefore more ecologically valuable than lying deadwood. Deadwood is used by a variety of organisms that have adapted to this habitat over the course of evolution. Depending on the type of wood and the degree of decomposition (stage of the decay process), around 600 species of large fungi and around 1350 species of beetles are involved in the complete remineralization of a wooden body. There are a wide variety of dependencies between fungi and insects. Insects transfer fungal spores to the wooden body, and the fungi can in turn be a source of food and partial habitat for insects.
