Site details
Site description: The pond was established in 1524 in a shallow valley of the Otava river. It is the largest pond of the Písek administrative region (104.5 ha) and it is situated about 10 km southwest of the city of Písek. It is a comparatively shallow fish-farming pond with a depth of about 1 m and extensive reedbeds and sedge stands. It is surrounded by an extensively managed agricultural landscape. East of the pond, behind an wind-deposited sand dam, there are pools (6.2 ha), which is what remained after the extraction of stucco-type sands in the area. Percolating water from the pond has created a unique mosaic of various environments in the pools.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: The IBA is important for both breeding and passage waterbirds.

Threats
Summary of threats to biodiversity at KBA: A serious threat is posed by excessive nutrient enrichment of the pond, caused by fish-farming, agricultural activities and a Larus ridibundus colony.
| Threat level 1 | Threat level 2 | Threat level 3 | Timing |
|---|---|---|---|
| Biological resource use | Hunting & collecting terrestrial animals | Unintentional effects (species being assessed is not the target) | Only in the future |
