Site description A section of the Danube flood-plain, situated at the entrance to Ðerdap gorge in the south-east Pannonian lowlands. Natural forests (willow Salix, poplar Populus, ash Fraxinus, oak Quercus), extensive Populus plantations, wet meadows and marsh, and dry grassland are present. There is heavy boat traffic on the Danube.

Key Biodiversity The site is important for breeding, wintering and passage waterbirds, regularly holding 60,000-100,000 individuals during winter and migration periods. This is also believed to be an important area for migrating storks˜during autumn migration in 1985, 2,000 Ciconia ciconia and 100 C. nigra were counted over five days from part of the site˜and also raptors, but further data on numbers are needed. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (resident) and Crex crex (5-10 breeding pairs).
