This sporting area is environmentally protected, and although the natural environment has been drastically altered throughout history for the purposes of agriculture and forestry, plans for afforestation will make it one of the major forests of Metropolitan France and a reserve for species such as the southern tulip and black grouse, two symbols of the park, as well as the re-introduced griffon vulture and the alpine ibex. The differences in climate and altitude across the Vercors are reflected in the high level of diversity in the fauna and flora.
