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 |
|---|---|---|---|---|
| Grey-green Fruit-dove Ptilinopus purpuratus | LC | resident (-) | common | A2 |
| Polynesian Swiftlet Aerodramus leucophaeus | LC | resident (-) | min 100 birds | A1, A2 |
| Tahiti Kingfisher Todiramphus veneratus | NT | resident (-) | common | A2 |
| Tahiti Monarch Pomarea nigra | CR | resident (2006) | 30–40 birds | A1, 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 (2016) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2016 | very poor | very high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | population | good | |

|---|---|---|---|---|---|
| Species | Actual vs Reference (units) | % remaining | Result | ||
| Tahiti Monarch Pomarea nigra | 53 / 250 (birds) | 22 | very poor | ||
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Invasive and other problematic species and genes | happening now | whole of population/area (>90%) | moderate decline (10–30% over 3 generations) | very high |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Most of area (50–90%) covered (including the most critical parts for important bird species) | No management plan exists, but the management planning process has begun | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
