Data Zone
The site was identified as internationally important for bird conservation in 2000 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 |
|---|---|---|---|---|
| Common Eider Somateria mollissima | NT | winter (1989) | 32,900 birds | A4i, B1i, C3 |
| Common Scoter Melanitta nigra | LC | winter (1989) | 48,920 birds | A4i, B1i, C3 |
| Velvet Scoter Melanitta fusca | VU | winter (1989) | 7,450 birds | A4i, B1i, C3 |
| A4iii Species group - waterbirds | n/a | unknown (1989) | 50,000-99,999 birds | A4iii, C4 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.
