Data Zone
The site was identified as important in 2004 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Tundra Swan Cygnus columbianus | LC | winter | 2003 | present | A4i |
| Bean Goose Anser fabalis | LC | passage | 2003 | present | A4i |
| Greater White-fronted Goose Anser albifrons | LC | passage | 2003 | present | A4i |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.
| IBA conservation assessment | |||

| Year of assessment | State | Pressure | Response |
| 2015 | near favourable | high | negligible |
