The forest is of great importance for the conservation of biodiversity in Switzerland. 134 lichen species are listed as forest target species (national priority species requiring action). 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.
Action Plan Sparse Forest
The action plan for sparse forest is a tool to preserve and promote the sparse forest and the diversity it harbours. More than 40 lichen species can benefit from this action plan. You can find more information about it on the website of InfoSpecies.
