Data Zone
The site was identified as internationally important for bird conservation in 2010 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 |
|---|---|---|---|---|
| Rarotonga Fruit-dove Ptilinopus rarotongensis | NT | resident (2003) | 50–250 adults | A1, A2 |
| Atiu Swiftlet Aerodramus sawtelli | VU | resident (2007) | 350–400 birds | A1, A2 |
| Chattering Kingfisher Todiramphus tutus | NT | resident (-) | common | A2 |
| Rimatara Lorikeet Vini kuhlii | EN | resident (2010) | 107 birds | A1 |
| Rarotonga Monarch Pomarea dimidiata | VU | resident (2006) | 37 adults | A1, A2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2018) is shown below.
| IBA conservation assessment | |||

| Threat | Timing | Scope | Severity | Result |
| Invasive and other problematic species and genes | happening now | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | high |

| Designation | Planning | Action | Result |
| Little/none of area covered (<10%) | No management planning has taken place | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
