Data Zone
The site was identified as important 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Whooper Swan Cygnus cygnus | LC | passage | 1996 | 1,000 individuals | A4i, B1i, C2 |
| Greylag Goose Anser anser | LC | passage | 1996 | 290 individuals | B1i, C3 |
| Bean Goose Anser fabalis | LC | passage | 1996 | 1,500 individuals | B1i, C3 |
| Common Crane Grus grus | LC | passage | 1996 | 2,800 individuals | A4i, B1i, C2 |
| Little Gull Hydrocoloeus minutus | LC | breeding | 1996 | 40 breeding pairs | B2 |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.
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.
