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 |
|---|---|---|---|---|
| Atoll Fruit-dove Ptilinopus coralensis | NT | resident (-) | 11 birds | A2 |
| Bristle-thighed Curlew Numenius tahitiensis | NT | non-breeding (2006) | 53 birds | A1 |
| Tuamotu Sandpiper Prosobonia parvirostris | EN | resident (-) | 15–70 birds | A1, A2, A4i |
| Tuamotu Reed-warbler Acrocephalus atyphus | LC | resident (-) | 55 unknown | A2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2006) is shown below.

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Invasive and other problematic species and genes | happening now | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | high |
| Agricultural expansion and intensification | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Climate change and severe weather | likely in short term (<4 years) | whole of population/area (>90%) | no or slight decline (<1% over 3 generations) | low |
