Data Zone
The site was identified as internationally important for bird conservation in 2008 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 |
|---|---|---|---|---|
| Tundra Swan Cygnus columbianus | LC | breeding (1995) | 2,500 birds | A4i |
| Brent Goose Branta bernicla | LC | passage (1974) | 6,112 birds | A4i |
| Snow Goose Anser caerulescens | LC | passage (1975) | 323,000 birds | A4i |
| Greater White-fronted Goose Anser albifrons | LC | passage (1974) | 23,700 birds | A4i |
| A4iii Species group - waterbirds | n/a | passage (-) | 20,000-49,999 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2013) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2013 | not assessed | high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | unset | unknown | |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Transportation and service corridors | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Energy production and mining | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Pollution | likely in long term (>4 years) | few individuals/small area (<10%) | rapid decline (>30% over 3 generations) | low |
