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 (2003) | 500–50,000 birds | A4i |
| Smew Mergellus albellus | LC | winter (2003) | 100–3,000 birds | A4i |
| Goosander Mergus merganser | LC | winter (2003) | 50–2,000 birds | A4i |
| Tufted Duck Aythya fuligula | LC | winter (2003) | 1,000–20,000 birds | A4i |
| Mallard Anas platyrhynchos | LC | winter (2003) | 1,000–50,000 birds | A4i |
| Common Teal Anas crecca | LC | winter (2003) | 1,000–30,000 birds | A4i |
| Dalmatian Pelican Pelecanus crispus | NT | winter (2003) | 50–1,000 birds | A1, A4i |
| Pygmy Cormorant Microcarbo pygmaeus | LC | winter (2003–2004) | 20–500 birds | A4i |
| A4iii Species group - waterbirds | n/a | winter (2003) | 20,000 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 (2018) is shown below.
