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) | 28–5,182 birds | A4i |
| Ruddy Shelduck Tadorna ferruginea | LC | winter (2007) | 90–6,010 birds | A4i |
| Common Crane Grus grus | LC | winter (2007) | 150–5,164 birds | A4i |
| Little Bustard Tetrax tetrax | NT | winter (2007) | 1–150 birds | A1 |
| A4iii Species group - waterbirds | n/a | winter (2007) | min 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.
