Site description An open expanse of agricultural land located near to the borders with Austria and Hungary. What was originally steppe has recently been converted to intensively managed arable farmland. The IBA includes dried-up meanders of the River Danube and a network of shelterbelts.

Key Biodiversity The IBA is important for steppic species and supports part of a transboundary population of Otis tarda (60-90 individuals) that moves between Slovakia, Austria and Hungary. The arable fields provide important winter roosting and feeding areas for geese, and hold 20,000 or more individuals of Anser fabalis, A. albifrons and A. anser on a regular basis. Breeding species of global conservation concern that do not meet IBA criteria: Crex crex.
