Data Zone
The site was identified as internationally important for bird conservation in 2007 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 |
|---|---|---|---|---|
| Buff-breasted Sandpiper Calidris subruficollis | VU | passage (2001) | 250-999 birds | A1, A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2014) is shown below.

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Human intrusions and disturbance | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Pollution | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Residential and commercial development | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Invasive and other problematic species and genes | happening now | few individuals/small area (<10%) | slow decline (1–10% over 3 generations) | low |
| Natural system modifications | past (and unlikely to return) and no longer limiting | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | low |
