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 |
|---|---|---|---|---|
| Red-breasted Goose Branta ruficollis | VU | passage (2004) | 102 birds | A1 |
| Greylag Goose Anser anser | LC | passage (1998) | 7,500 birds | A4i |
| Greater White-fronted Goose Anser albifrons | LC | passage (2004) | 12,000 birds | A4i |
| Lesser White-fronted Goose Anser erythropus | VU | passage (2004) | 36 birds | A1 |
| Little Gull Hydrocoloeus minutus | LC | breeding (1998) | 1,500 pairs | A4i |
| A4iii Species group - waterbirds | n/a | passage (2004) | 20,000-49,999 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 (2015) is shown below.
