This kind of forest management has also changed the forest landscape profoundly. Natural forest dynamics produce key resources and processes important for the maintenance of native forest biodiversity, in particular a rich supply of dead wood and old trees, as well as a varied landscape pattern of such resources, critical for the long-term survival of many forest species. In addition to the dead wood and old trees resulting from natural forest dynamics, forest biodiversity will also benefit from productive forests with a rich supply of temperate broadleaved trees or aspens, willows and rowans, as well as special forest types like swamp forests, forests on calcareous soil, or recently burnt forests. Several forest properties of high importance for biodiversity are monitored in national forest inventories, e.g., tree species and age, dead wood, and site productivity.
