Data Zone
The site was identified as internationally important for bird conservation in 2007 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 |
|---|---|---|---|---|
| Greylag Goose Anser anser | LC | winter (2007) | 323–12,868 birds | A4i |
| Lesser White-fronted Goose Anser erythropus | VU | winter (2007) | 7–18 birds | A1 |
| Ruddy Shelduck Tadorna ferruginea | LC | winter (2007) | 528–2,986 birds | A4i |
| Demoiselle Crane Anthropoides virgo | LC | passage (2007) | 28–1,004 birds | A4i |
| Common Crane Grus grus | LC | passage (2007) | 18–1,103 birds | A4i |
| Great Cormorant Phalacrocorax carbo | LC | winter (2007) | 108–4,640 birds | A4i |
| A4iii Species group - waterbirds | n/a | winter (2007) | 3,091–20,825 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.
