Data Zone
The site was identified as internationally important for bird conservation in 2012 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 |
|---|---|---|---|---|
| Sooty Tern Onychoprion fuscatus | LC | breeding (1974) | 400,000 birds | A4i |
| A4iii Species group - waterbirds | n/a | breeding (1974) | 404,050 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2012) is shown below.

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | likely in long term (>4 years) | whole of population/area (>90%) | moderate decline (10–30% over 3 generations) | high |
| Transportation and service corridors | likely in long term (>4 years) | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | medium |
| Biological resource use | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Invasive and other problematic species and genes | likely in long term (>4 years) | whole of population/area (>90%) | no or slight decline (<1% over 3 generations) | low |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
