Dead wood is an essential factor in preserving biodiversity in forests. A vast number of mushrooms, insects (such as beetles, flies and midges, wild bees, ichneumon wasps and butterflies), woodpeckers, bats and many plants and other animals depend on dead wood. Because each species places its own demands on the habitat, only dead wood in its many varieties can secure the survival of them all: various degrees of decomposition, upright - fallen, sunny - shaded, moist - dry, various dimensions, tree types, heights and cavities. Upright dead wood in sunny locations and with large dimensions is especially important. Due to the smaller amounts of dead wood currently found in commercial forests, the existence of many dead wood inhabitants is threa - tened and in some regions they have become extinct. The aim of this brochure is to encourage forest owners, foresters and forestry workers to leave more dead wood in the forest, to create islands of dead wood and to select trees that will not be put to use even after they are dead. This actions are strictly limited to a good phytosanitaric situation on these forest sites. In high-altitude areas, dead wood also plays an important role in the regeneration of forest sites. This brochure also looks at the importance of dead wood in residential areas, such as gardens, parks and sparse orchards. It gives numerous tips for encouraging dead wood in commercial forests and in residential areas, points out sources of danger associated with it and how to minimize them.
