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 |
|---|---|---|---|---|---|
| Atoll Fruit-dove Ptilinopus coralensis | NT | resident | 1984 | 10 breeding pairs | A1, A2 |
| Gygis alba | NR | resident | - | 3,000 individuals | A4i |
| Blue Lorikeet Vini peruviana | VU | resident | 1984 | 20 breeding pairs | A1, A2 |
| Tuamotu Reed-warbler Acrocephalus atyphus | LC | resident | 1984 | 150 breeding pairs | A2 |
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.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2012 | not assessed | high | negligible |
