The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Magnificent Frigatebird Fregata magnificens	LC	breeding (-)	3,000 pairs	A4i
Brown Booby Sula leucogaster	LC	breeding (-)	1,500 pairs	A4i

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 (<4 years)	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation (management category)	% coverage of IBA
