Data Zone
The site was identified as internationally important for bird conservation in 2009 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 |
|---|---|---|---|---|
| Little Penguin Eudyptula minor | LC | resident (2007) | 26,000 birds | A4ii |
| Short-tailed Shearwater Ardenna tenuirostris | LC | resident (2007) | 450,000 nests | A4ii |
| Hooded Plover Thinornis cucullatus | VU | resident (2000–2007) | 21–42 birds | A1 |
| Pacific Gull Larus pacificus | LC | non-breeding (2001–2007) | 52–490 birds | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.
