Data Zone
The site was identified as important in 2008 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 |
|---|---|---|---|---|---|
| Lesser Frigatebird Fregata ariel | LC | breeding | 1977 | 7,000 individuals | A4ii |
| Great Frigatebird Fregata minor | LC | breeding | 1977 | 3,000 individuals | A4ii |
| Red-footed Booby Sula sula | LC | breeding | 1977 | 5,000 individuals | A4ii |
| Masked Booby Sula dactylatra | LC | breeding | 1977 | 3,000 individuals | A4ii |
| A4iii Species group - seabirds | n/a | breeding | 1977 | 20,000 individuals | A4iii |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2008) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2012) is shown below.
