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
Red-footed Booby Sula sula	LC	breeding	1992	6,000-10,000 individuals	A4ii
Black Noddy Anous minutus	LC	breeding	1979	20,000 individuals	A4i
Gygis alba	NR	breeding	1992	6,000-10,000 individuals	A4i
A4iii Species group - waterbirds	n/a	breeding	1979	23,050-25,100 individuals	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 (2018) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	slow but significant deterioration	high
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	slow but significant deterioration	medium
Human intrusions and disturbance	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
