The site was identified as important in 2009 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	resident	1980-2002	700-1,660 nests	A4ii
Brown Booby Sula leucogaster	LC	resident	1980-2002	3,700-16,000 nests	A4ii
Masked Booby Sula dactylatra	LC	resident	1980-2002	700-2,500 nests	A4ii
Brown Noddy Anous stolidus	LC	resident	1980-2002	50,000 individuals	A4i
Black Noddy Anous minutus	LC	resident	1980-2002	50,000 individuals	A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high
Other	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high

Year	Protected Area	Designation	% overlap with IBA
