Species promotion in the forest

The forest is of great importance for the conservation of biodiversity in Switzerland. Intensive forest use has led to the loss of diverse structures and in many places to a shortage of old-growth and deadwood, the basis of life for a large number of endangered species in the forest. The FOEN's enforcement aid Biodiversity in Forests: Objectives and Measures (2015) aims to promote and maintain biodiversity in Swiss forests. 134 lichen species are listed as forest target species (national priority species requiring action).
