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 |
|---|---|---|---|---|
| Polynesian Storm-petrel Nesofregetta fuliginosa | EN | resident (1990) | 2 birds | A1 |
| Herald Petrel Pterodroma heraldica | LC | resident (1975) | 800–1,200 pairs | A4ii |
| Phoenix Petrel Pterodroma alba | VU | breeding (1989) | 32–62 pairs | A1, A4ii |
| Tropical Shearwater Puffinus bailloni | LC | breeding (1998) | 1,000–2,000 pairs | A4ii |
| Sooty Tern Onychoprion fuscatus | LC | breeding (-) | 1,000,000–1,500,000 birds | 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.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2012 | good | medium | very low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | poor | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Neritic | good (>90%) | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Pollution | happening now | most of population/area (50–90%) | no or slight decline (<1% over 3 generations) | low |
| 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 |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Some of area covered (10–49%) | No management planning has taken place | Very little or no conservation action taking place | very low |
| Habitat | % of IBA | Habitat detail |
