A pond complex with adjacent wet meadows, riverine forests and arable land, situated between the Wisznia river (the San tributary) and the Bucowski Canal near to the Polish-Ukrainian border. Most of the pond area is overgrown with submerged pondweed Potamogeton, floating water-lilies Nymphaea and fringing belts of reed Phragmites. The ponds are intensively used for fish-farming.

Species of global conservation concern that do not meet IBA criteria: Aythya nyroca (3-4 pairs), Haliaeetus albicilla (one non-breeding bird), Crex crex.
