Broadleaved and coniferous woodlands are extensive, with relatively unspoilt alpine grasslands and rocky areas. The main land-uses are cattle-rearing, forestry and tourism.

Key biodiversity

Pressure/threats to key biodiversity
The main threats are abandonment of land management, extraction industry (quarries), and tourism, the last one especially linked to disturbance of grouse. There is research on the population density of Tetrao tetrix in the Regional Nature Park.
