The biodiversity of oak forests is declining as a result of intensive human use. With the nature conservation interventions of the LIFE4OAK FORESTS project, our goal is to reverse this process. The project aims to promote the regeneration of the forests and to restore the diversity of forest structure, native tree species composition and micro habitats. As a results, the protected forest mammals, birds, insects, plants and fungi will be preserved and their populations will increase. The project is co-financed by the European Union’s LIFE program.
