The Site is formed by freshwater tree-dominated wetlands, river branches, oxbow lakes, marshland, meadows and reedbeds, located on the active floodplain of the southernmost part of the River Danube, adjacent to Ramsar Sites in Serbia and Croatia. The river is characterized by its high biodiversity, providing shelter to threatened species of mammals, amphibians, reptiles and molluscs including the thick shelled river mussel, as well as many protected waterbird species such as the Eurasian bittern (Botaurus stellaris), black stork (Ciconia nigra) and corn crake (Crex crex). The Site also supports threatened breeding birds such as the little egret (Egretta garzetta) and the black-crowned night heron (Nycticorax nycticorax). The floodplain plays an important role in sediment trapping. The water level is artificially regulated by a sluice system, allowing fish to spawn in the retained flooded area. Human activities include fishing, forestry and hunting. There is a nature education centre in the area. Potential threats to the ecological character of the Site are colonization by invasive tree species such as maple ash, poplar and eastern black walnut, and overgrazing by wild animals such as red deer and wild boar. In the surrounding area, the deepening of the riverbed due to former river regulation has caused water levels to fall.
