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 |
|---|---|---|---|---|
| Samoan Fruit-dove Ptilinopus fasciatus | LC | resident (1986) | min 2,000 birds | A2 |
| Tahiti Petrel Pseudobulweria rostrata | NT | breeding (2002) | 1,000-2,499 pairs | A1, A4ii |
| Blue-crowned Lorikeet Vini australis | LC | resident (1986) | min 5,200 birds | A2 |
| Polynesian Wattled Honeyeater Foulehaio carunculatus | LC | resident (1986) | min 47,500 birds | A2 |
| Fiji Shrikebill Clytorhynchus vitiensis | LC | resident (1986) | min 6,000 birds | A2 |
| Polynesian Starling Aplonis tabuensis | LC | resident (1986) | min 2,100 birds | A2 |
| Samoan Starling Aplonis atrifusca | LC | resident (1986) | min 10,000 birds | A2 |
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.

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | likely in long term (>4 years) | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | medium |
| Invasive and other problematic species and genes | happening now | whole of population/area (>90%) | no or slight decline (<1% over 3 generations) | low |
| Pollution | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Biological resource use | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |

| Designation | Planning | Action | Result |
| Most of area (50–90%) covered (including the most critical parts for important bird species) | A management plan exists, but it is out of date or not comprehensive | Very little or no conservation action taking place | low |
