The site, located in the Group of Mount Coglians, plays a particularly important role in the Natura 2000 network of Friuli Venezia Giulia as it includes a very large portion of the main Carnic Chain with all the alpine habitats of both carbonate and acid substrates. It includes the best examples of screes and siliceous rocks, pastures of significant size and some small alpine lake systems. The site has, in addition to numerous rare species, some points of Eryngium alpinum, a species of community interest currently in strong rarefaction. The contribution to the network is represented by the presence of high-altitude mountain massifs (on a regional scale) which constitute one of the last reproductive sites for the white partridge (Lagopus mutus) and for the golden eagle (Aquila chrysaetos). The area also presents suitable environmental situations for vulturids and is rich in ungulates. This site actually represents an important element of connection within the Natura 2000 network of the Veneto Region and Austria.
