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 |
|---|---|---|---|---|
| Red-tailed Tropicbird Phaethon rubricauda | LC | breeding (2006) | 500 pairs | A4ii |
| Lesser Frigatebird Fregata ariel | LC | breeding (2006) | 4,000 pairs | A4ii |
| Masked Booby Sula dactylatra | LC | breeding (2006) | 500 pairs | A4ii |
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 |
| Invasive and other problematic species and genes | happening now | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | high |

| Residential and commercial development | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |

| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
