Data Zone
The site was identified as internationally important for bird conservation in 2014 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 |
|---|---|---|---|---|
| Long-tailed Duck Clangula hyemalis | VU | passage (2004–2014) | 300–1,800 birds | A1 |
| Red-breasted Merganser Mergus serrator | LC | non-breeding (2004–2013) | 1,000–2,000 birds | B1i |
| Arctic Herring Gull Larus smithsonianus | LC | passage (2004–2013) | 15,000 birds | B1i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2017) is shown below.
