Data Zone
The site was identified as internationally important for bird conservation in 2000 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Common Pochard Aythya ferina | VU | breeding (1997) | 146 pairs | B3 |
| Red-necked Grebe Podiceps grisegena | LC | breeding (1997) | 93 pairs | B1i, C3 |
| Spotted Crake Porzana porzana | LC | breeding (1997) | 26 pairs | B3, C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.
