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 |
|---|---|---|---|---|
| White-winged Petrel Pterodroma leucoptera | VU | breeding (2004–2007) | 5,000–18,000 pairs | A1, A4ii |
| Fairy Tern Sternula nereis | VU | breeding (2012) | 240 birds | A1, A4i |
| Roseate Tern Sterna dougallii | LC | breeding (2012) | 2,000 pairs | A4i |
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.

| Climate change and severe weather | likely in long term (>4 years) | whole of population/area (>90%) | no or slight decline (<1% over 3 generations) | low |
