Description
Floristic richness, the presence of rare species (Forcella Paschè-Colle Ombert area) and important vegetation and landscape aspects - e.g. the sheer cliffs of Mearins - amply justify the designation of the site.
The site is of relevant national and/or provincial interest for the presence and reproduction of endangered animal species, important glacial relicts, exclusive and/or typical of the Alps.
Habitats of special interest not included in Annex I of Directive 92/43/EEC are present: large expanses of species-rich Festuca variae (Festucetum variae, Knautio-Trifolietum thalii) (30%).
