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 |
|---|---|---|---|---|---|
| Brown Booby Sula leucogaster | LC | breeding | 2004 | 851 breeding pairs | A4ii |
| Blue Noddy Anous ceruleus | LC | breeding | 2004 | 260 breeding pairs | A4i |
| A4iii Species group - waterbirds | n/a | breeding | 2004 | 9,661 breeding pairs | A4iii |
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.
