The reasons for proclamation of Kornati National Park were numerous. Numerous bigger or smaller islands, scattered about the sea, leave an impression of a sea labyrinth on the land or a land labyrinth in the sea. Dominating species are great sage, feather grass and false brome grass. On some particular islands there are degraded holm-oak tree forest. Few rare pine trees only intensify the atmosphere of bareness.
Local inhabitants use few small karst fields to cultivate olives, figs, grapes, cherries, etc.
Every bed, fault or fold leaves a deep trace in the memory of every visitor. Thin patches of res soil, made up by gradual wearing of surrounding carbonate rocks, can be found only in the few small karst fields. Numerous holes, clefts, vaults, caves and submarine meadows offer shelter to such a variety of sea organisms. The land area of the park is rather poor in animal species. Beside some species of butterflies, centipedes, spiders, scorpions and snails, we can also find frogs, lizards, snakes, pond-terrapins, bats, rats, mice, hares and voles.
