Data Zone
The site was identified as important 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Tahiti Petrel Pseudobulweria rostrata | NT | breeding | 1996 | 100 breeding pairs | A1, A4ii |
| Black Noddy Anous minutus | LC | breeding | 1996 | 50,000-100,000 breeding pairs | A4i |
| Fairy Tern Sternula nereis | VU | breeding | 2004 | 11 nests | A1 |
| Roseate Tern Sterna dougallii | LC | resident | 2007 | 1,500 breeding pairs | A4i |
| A4iii Species group - seabirds | n/a | breeding | 2007-2012 | 208,000 breeding pairs | A4iii |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2012) may differ.
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.

| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | likely in long term (beyond 4 years) | whole area/population (>90%) | slow but significant deterioration | medium |
| Human intrusions and disturbance | happening now | some of area/population (10-49%) | no or imperceptible deterioration | low |
| Invasive and other problematic species and genes | likely in short term (within 4 years) | majority/most of area/population (50-90%) | no or imperceptible deterioration | low |
| Biological resource use | happening now | some of area/population (10-49%) | no or imperceptible deterioration | low |
| Pollution | happening now | small area/few individuals (<10%) | no or imperceptible deterioration | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||

| Protected areas | Management plan | Other action | Result |
| Some of site covered (10-49%) | A management plan exists but it is out of date or not comprehensive | Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity | low |
