Site description The site consists of a fish-pond complex in an area of old marsh, fed by the Crisul Negru river and surrounded by the Corhana canal. Reedbeds (Phragmites) grow along the dykes and edges of the fish-ponds. The site also includes agricultural fields, grasslands and hay meadows and to the south the Rãdvani forest which is dominated by Quercus and Ulmus.

The site holds 20,000 or more waterbirds on passage on a regular basis (includes 7,000 Anser albifrons, 2,500 Anas crecca, 1,160 Anas platyrhynchos, 2,000 Calidris alpina). Rãdvani wood holds a heronry.
