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 |
---|---|---|---|---|
Tahiti Petrel Pseudobulweria rostrata | NT | breeding (1996) | 100 pairs | A1, A4ii |
Black Noddy Anous minutus | LC | breeding (1996) | 50,000–100,000 pairs | A4i |
Fairy Tern Sternula nereis | VU | breeding (2004) | 11 nests | A1 |
Roseate Tern Sterna dougallii | LC | resident (2007) | 1,500 pairs | A4i |
A4iii Species group - seabirds | n/a | breeding (2007–2012) | 208,000 pairs | A4iii |
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 |
Climate change and severe weather | likely in long term (>4 years) | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | medium |
Human intrusions and disturbance | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
Biological resource use | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
Pollution | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
Invasive and other problematic species and genes | likely in short term (<4 years) | most of population/area (50–90%) | no or slight decline (<1% over 3 generations) | low |
