Protected flora grows in the rocky crevices of the Trnovo Forest Plateau, which is 75.5 percent forest, and covered mostly by mixed beech and fir.
Protected flora grows in the rocky crevices, including the Carniolan primrose (Primula carniolica). The share of forest is 75.5%, but this is increasing because of the afforestation of abandoned farmland. The Trnovo Forest Plateau is covered by mixed beech and fir forest (Abieti-fagetum dinaricum).
