The IBA is situated near to the industrial agglomeration of Ostrava, and contains a system of four large fish-ponds (totalling 480 ha) and extensive areas of reedbed (Phragmites) (totalling 100 ha). A network of canals and streams empty into the Odra river and its tributary, the OLse river. Oxbow lakes, sandpits and remnants of flood-plain forest adjoin the latter.
Nationally important populations of Botaurus stellaris, Ixobrychus minutus, Porzana porzana, Tringa totanus, Limosa limosa, Luscinia svecica cyanecula and Panurus biarmicus breed here. The fish-ponds are also important for up to 5,000 wintering and migrating wildfowl. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (2 wintering birds).
Pressure/threats to key biodiversity
This IBA is threatened by the construction of the D47 highway and, more importantly by the planned greenfield industrial zone in the floodplain of the Olza river, an only substantial feeding ground of the Marsh Harrier.
