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 |
|---|---|---|---|---|
| Polynesian Ground Dove Pampusana erythroptera | CR | resident (-) | 10–12 birds | A1, A2 |
| Atoll Fruit-dove Ptilinopus coralensis | NT | resident (-) | common | A1, A2 |
| Bristle-thighed Curlew Numenius tahitiensis | NT | non-breeding (-) | min 100 birds | A1, A4i |
| Gygis alba | NR | breeding (-) | 1,000 pairs | A4i |
| Blue Lorikeet Vini peruviana | VU | resident (2006) | 1,249 birds | A1, A2 |
| Tuamotu Reed-warbler Acrocephalus atyphus | LC | resident (-) | rare | 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 (2012) is shown below.
