Site description A poorly-drained flood-plain situated between alluvial fans, and overlain by meadow and saline soils. The site is made up of four subsites: Nagy-Kerek-tiszta at Püspökladány, Gatály at Szerep, ásvány at Bihardancsháza, and the largest site, which lies between Váncsod and Csökmõ. The area is dominated by saline grasslands, which form a mosaic with extensive arable lands. Human activities include cattle- and sheep-grazing, goose and arable farming.

Key Biodiversity An important area for birds of lowland dry grassland. The site is part of a wider network of grassland fragments and includes areas that hold important local populations of Otis tarda. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (8 wintering birds), Aquila heliaca (1-5 birds on passage).
