Data Zone
The site was identified as important 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 List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Great Frigatebird Fregata minor | LC | breeding | 1988 | 2,427 breeding pairs | A4ii |
| Red-footed Booby Sula sula | LC | breeding | 1988 | 2,221 breeding pairs | A4ii |
| Black Noddy Anous minutus | LC | breeding | 1988 | 8,392 breeding pairs | A4i |
| Gygis alba | NR | breeding | 1988 | 3,957 breeding pairs | A4i |

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2012) may differ.
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 | favourable | low | negligible |
| 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%) | favourable |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Pollution | happening now | some of area/population (10-49%) | no or imperceptible deterioration | low |
| Climate change and severe weather | likely in long term (beyond 4 years) | majority/most of area/population (50-90%) | no or imperceptible deterioration | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
