The site includes pre-alpine mountain systems of extreme floristic and phytogeographic interest. In addition to the numerous endemisms there are the only Italian stations of Gentiana froelichii, Thlaspi minimum and Aurinia petraea. The plateau of Mount Canin presents important epigean and hypogean karst phenomena, with the presence of Eryngium alpinum and Campanula zoysii. The most widespread habitats are beech-woods, endemic black-pine pine forests, calciferous moors and mountain pines, calcareous alpine floors, and the vast system of alpine meadows on limestone, screes (both thermophilic and alpine) and cliffs. Tourist activities are relatively limited, especially on the southern hills where the morphology of the slopes is very harsh. Pre-Alpine area is of national ornithological importance, due to its relation to the typical biocenosis richness. The area is characterized by abundant populations of Horvath’s rock lizard (Iberolacerta horvathi), Horned viper (Vipera ammodytes), common European vipera, Asp, and Yellow-bellied (Bombina variegata). There are also discrete populations of Black salamander (Salamandra atra), Mediterranean water shrew (Neomys anomalus) and Dice snake (Natrix tessellata). Wild cat (Felis silvestris), Brown bear (Ursus arctos), European lynx (Lynx lynx) and Lepus timidus make frequent appearances in the area. In running waters there are populations of River crayfish (Austropotamobius pallipes), European bullhead (Cottus gobio) and Marble trout (Salmo [trutta] marmoratus). Among the protected insect species there are Lucanus cervus, Rosalia alpina, Cerambyx cerdo and Morimus funereus beetles. In Zamlin (Resia), Austropotamobius torrentium, Erebia calcari, Helix pomatia and Vertigo angustior have been reported.
