The area is characterized by a relatively gentle environment and scarce vegetation cover and houses the one and only known station of Euphorbia gibelliana, an endemic species of Piedmont with an extremely limited distribution range. It is a characteristic mountain perennial heliophilous species living in thin woodlands of lime tree, birch, and downy oak. The area is populated by the characteristic alpine wildlife represented by mammals, several rodents, and species belonging to the genus Microtus, as well as common hares, weasels, polecats, badgers, and foxes. The access is not allowed, except every year on 5th August for the celebration of Madonna della Neve, to which the homonymous chapel on Mt. Sap is dedicated. In the other periods, the access to the area is allowed only for scientific research reasons, with an authorization issued by the Park Authority.
