The forests occupy nearly a third of the territory of the Auvergne Volcanoes Regional Nature Park. The varieties of trees depend on the altitude (from 1,312 to 6,184 ft / 400 to 1,885 m), the nature of the rock (volcanic or granite), the climatic influences, and the silvicultural management. The area is, therefore, home to oak groves, pine forests, spontaneous birch woodlands, fir beech groves, and non-native softwood plantations of Douglas-fir or spruces. Recreational spaces and reservoirs of biodiversity, these regular, irregular, or free-changing forests are also intended for producing wood for heating, timber, or industry.
