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 |
|---|---|---|---|---|
| Greylag Goose Anser anser | LC | passage (2007–2013) | 1,460–6,200 birds | B1i |
| Pink-footed Goose Anser brachyrhynchus | LC | passage (2010–2013) | 620–2,500 birds | B1i |
| Velvet Scoter Melanitta fusca | VU | passage (2005–2014) | 50–130 birds | 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 (2016) is shown below.
