The Gornje Podunavlje is positioned in the alluvial zone of the Danube (1367-1433 river km), in the upper course in Vojvodina Province at the far northwestern parts of Serbia. It comprises the alluvial plane of the left riverbank of the Danube along the length of 64 km and it represents the largest marsh/wetland complex on the Danube course in Serbia. This lowland area is characterised by flat or slightly undulating relief with meanders, chanells, old river courses, islets and rigdes. Beside smaller parts covered with wet meadows, reedsbeds, swamps and Kolut and Svilojevo carp fish-ponds this area mainly consists of oak, poplar, willow forest communities. Along the IBA borders there are seven settlements divided into Apatin and Sombor municipalities.
