Data Zone
The site was identified as internationally important for bird conservation in 1994 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 |
|---|---|---|---|---|
| Grey Plover Pluvialis squatarola | VU | passage (1991) | 500 birds | B1i |
| Kentish Plover Charadrius alexandrinus | LC | passage (1991) | 1,500 birds | A4i, B1i |
| Kentish Plover Charadrius alexandrinus | LC | winter (1988–1992) | 330–731 birds | B1i |
| Charadrius mongolus | NR | passage (1991) | 2,000 birds | A4i, B1i |
| Charadrius mongolus | NR | winter (1988–1992) | 233–824 birds | B1i |
| Broad-billed Sandpiper Calidris falcinellus | VU | passage (1991) | 800 birds | A4i, B1i |
| Dunlin Calidris alpina | NT | winter (1988–1992) | 616–1,586 birds | B1i |
| Slender-billed Gull Larus genei | LC | passage (1991) | 3,000 birds | A4i, B1i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1994. The most recent assessment (2007) is shown below.
