The site was identified as important in 2006 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
Magnificent Frigatebird Fregata magnificens	LC	breeding	-	3,000 breeding pairs	A4i
Brown Booby Sula leucogaster	LC	breeding	-	1,500 breeding pairs	A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2006) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2024) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in short term (within 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
