In the south-east part of the Panon plain, in Banat, the biggest continental sands are found. They occupy the area of almost 35.000 hectares. It has oval shape and it is oriented in the direction south-east – north-west. It appeared during the Ice Age, from the great alluvium of eloian silicate-carbon sand. In the contemporary period the wind Košava has shaped the extreme dune relief, which altitudes reach between 70 and 200 meters. Continental climate, the absence of surface watercourses and sandy ground made conditions for certain life communities, which are separated in a special vegetal-geographical group Deliblaticum.
In the unique ecosystem mosaic, there are typical species of flora and fauna, among which many are rare and significant according to international criteria. The rich flora with over 900 species, subspecies and varieties abounds with rarities, relicts, endemics and sub endemics, such as Banat Peony, Pančić Absinthe, Serpa, Almond, Dwarf Everlast and Juniper – the only indigenous conifer of Panon plain. As the last and the biggest oasis of sand-steppe, forest and swamp vegetation, which previously dominated the Panon Plain, the Special Reservation of “Deliblat sands” is one of the biggest centers of biodiversity in Serbia and Europe, as well as the most important steppe area in the surroundings. This is why the reservation represents a unique scientific range.
Among the rarities in fauna the species from steppe habitats which stand out: Desert Ant, Ant Lion, Banat Falcon, Imperial Eagle, Steppe Gerbil, Ground Squirrel, Mole Rat, Steppe Polecat, and others. For some of them, “Deliblat sands” is the only or one of the rare remaining habitats in Serbia. The specificity of the reservation is the permanent population of the wolf.
Within the protected natural resources there is also one part of the River Danube with its fens and islands. The waters rich with fish and hatcheries represent a significant meeting place and a mass wintering place for many birds of water habitats. Because of that “Deliblat sands” was pronounced the internationally significant bird habitat (IBA) in 1989. Many rare species nest here: Little Egret, Yellow Egret, Ibis and Sand-martin. Pygmy Cormorant – globally endangered species – has a safe nesting place here.
Educational center “Čardak” was established in 2010. The purpose of the center is to raise the consciousness of the users of this area about the necessity of the protection of nature and prevention of the decline in biological diversity through presentations and organized education on the principals of sustainable economy in households, supervision and management. In this way the center brings the Reservation closer to the standards of the European Union.
Typical villages found on the border of the protected natural resources keep the atmosphere of the past time and also make this picturesque scenery complete.
