Ornithological information The IBA is important for both breeding and migratory wildfowl. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (breeding and wintering), Crex crex (breeding, no data). 206 species have been recorded either as having bred or as having occurred whilst on migration.
Site description A former marshland on the southern side of Lake Balaton, where only small fragments of original habitat remain following land reclamation. The IBA comprises hay meadows and arable land with scattered Alnus and Salix woodlands, wet meadows, reedbeds (Phragmites), an extensive ditch network and several fish-ponds. Human activities include arable farming, cattle-grazing, haymaking and reed-harvesting (`Other' land-use, below).

Management considerations Grasslands and reedbeds are threatened by uncontrolled burning, whilst the development of the M7 motorway will probably destroy the most valuable habitats. The designation of several smaller protected areas is in process.
