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 |
|---|---|---|---|---|
| Black Noddy Anous minutus | LC | breeding (2004) | 25,000 birds | A4i |
| A4iii Species group - waterbirds | n/a | breeding (2004–2005) | 32,500 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 (2018) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2018 | not assessed | high | medium |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | unset | good | |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Invasive and other problematic species and genes | happening now | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | high |
| Climate change and severe weather | likely in long term (>4 years) | whole of population/area (>90%) | moderate decline (10–30% over 3 generations) | high |
| Human intrusions and disturbance | past (and unlikely to return) and no longer limiting | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | low |
| Biological resource use | past (and unlikely to return) and no longer limiting | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | A management plan exists, but it is out of date or not comprehensive | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | medium |
