Dead wood comes alive (for insects) Characteristic feature of a natural forest is the existing deadwood. Basically, one understands among these dead trees or only parts of the tree that have died. They decompose more or less quickly.
The more forms of dead wood occur in the forest, the greater the diversity of species found there. As the dead wood decays, the bark begins to dissolve and provides habitat for many species of insects such as flies, mosquitoes, beetles, spiders, wood wasps or snails. After the bark has been decomposed, fungi also penetrate the internal wood body and make the core particularly interesting for many insect species.
The deadwood not only provides shelter, but also cover, a wintering place and a place to sleep for a variety of animals that are not involved in the mining itself. These include, for example, the forest ant, wild bees, grave wasps, toads, frogs, salamanders, newts, birds and various mammals.
For example, the wild bees and digger wasps house their brood in the decayed trunks. In their development, around a quarter of all beetle species in Germany depend on deadwood. The dead wood is an important basis for the great wealth of plants and animals in the forest.
