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 IBA criteria.
Populations meeting IBA criteria ('key species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Barnacle Goose Branta leucopsis | LC | passage (2004–2013) | 3,000 individuals | B1i |
| Pink-footed Goose Anser brachyrhynchus | LC | passage (2004–2013) | max 1,500 individuals | B1i |
| Eurasian Curlew Numenius arquata | NT | breeding (2004–2013) | 25–75 breeding pairs | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2019) is shown below.
