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 |
|---|---|---|---|---|
| Common Eider Somateria mollissima | NT | winter (2000–2006) | 15,000 birds | B1i, C3 |
| Caspian Tern Hydroprogne caspia | LC | breeding (2000–2006) | 190 pairs | A4i, B1i, B2, C2, C6 |
| Black Guillemot Cepphus grylle | LC | breeding (2000–2006) | 150 pairs | B2 |
| Razorbill Alca torda | LC | breeding (2000–2006) | 1,167 pairs | B1ii, B3, C3 |
| Common Murre Uria aalge | LC | breeding (2000–2006) | 1,046 pairs | B1ii, C3 |
| A4iii Species group - waterbirds | n/a | winter (2000–2006) | 20,000-49,999 birds | A4iii, C4 |
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.

| Human intrusions and disturbance | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Natural system modifications | happening now | few individuals/small area (<10%) | moderate decline (10–30% over 3 generations) | low |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Most of area (50–90%) covered (including the most critical parts for important bird species) | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | medium |
