Data Zone
The site was identified as internationally important for bird conservation in 2016 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.
Populations meeting IBA criteria ('key species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Polynesian Storm-petrel Nesofregetta fuliginosa | EN | breeding (1989–1990) | 35–199 breeding pairs | A1, A4ii |
| Murphy's Petrel Pterodroma ultima | LC | breeding (1989–1990) | 10–99 breeding pairs | A1 |
| Rapa Shearwater Puffinus myrtae | CR | breeding (1974) | 265–380 breeding pairs | A1, A4ii |
| Blue Noddy Anous ceruleus | LC | breeding (1989–1990) | 250–700 breeding pairs | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2016) is shown below.
