Data Zone
The site was identified as important 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 List1 | Season | Year(s) | 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 individuals | A1, A2 |
| Chattering Kingfisher Todiramphus tutus | NT | resident | - | common | A2 |
