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 |
---|---|---|---|---|
Whooper Swan Cygnus cygnus | LC | passage (1996) | 1,000 birds | A4i, B1i, C2 |
Greylag Goose Anser anser | LC | passage (1996) | 290 birds | B1i, C3 |
Bean Goose Anser fabalis | LC | passage (1996) | 1,500 birds | B1i, C3 |
Common Crane Grus grus | LC | passage (1996) | 2,800 birds | A4i, B1i, C2 |
Little Gull Hydrocoloeus minutus | LC | breeding (1996) | 40 pairs | B2 |
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.
