Site details
Site description: Two pond complexes (769 ha and 179 ha) on the Szprotawa river catchment (a tributary of the Bóbr river), with scattered forest of ash Fraxinus and alder Alnus (75 ha). Shoreline reedbeds Phragmites cover 6% of the ponds' area. Dams are generally treeless. Extensive meadows, sedge-beds and willow Salix bushes adjoin this area.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas)
Additional biodiversity: More than 20,000 waterbirds occur regularly on autumn passage, mainly wildfowl and Fulica atra. Breeding species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (one pair), Crex crex (one pair).

Threats
Summary of threats to biodiversity at KBA: High production of organic debris in the ponds leads to a gradual shallowing, sometimes to the extent that the islets used by nesting birds become accessible to mammalian predators. Another problem is that the fish-ponds are rented nowadays, and thus the pressure to reduce bird predation on the fishery has increased. If the ponds are privatized, the presence of waterbirds will be tolerated even less.
