Committed for many years to the preservation of the natural heritage in Auvergne, CEN Auvergne is currently strengthening its network of old forests through the acquisition of old forest parcels that will be left in free evolution. The constitution and preservation of these islands is part of the project "Sylvae: network of old forests in Auvergne”. At the same time, CEN Auvergne also continues to preserve peatlands with the acquisition of new plots in the department of Puy-de-Dôme and Cantal.
