Rich fossil fauna is preserved and almost 90% of the park area is forested. The predominant tree species include linden, oak and beech. The concentration of linden forests is highest in Europe. In time, linden became the dominant tree species, replacing formerly much larger and dominant oak forests, which are considered to be the autochthonous vegetation on Fruška Gora. Altogether, 1,500 plant species inhabits the park, of which 200 are protected. There are also 400 species of fungi. Pannonian plant endemites include Tatar dock ("Crambe tataria"), broadleaf wild leek and Hungarian leopard's-bane. There are some 30 species of orchids in the park.
