The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Lesser Frigatebird Fregata ariel	LC	breeding (2010)	5,058 birds	A4ii

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
Marine Coastal/Supratidal	-	moderate (70–90%)	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (>4 years)	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	medium
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	very low

Habitat	% of IBA	Habitat detail
Marine Coastal/Supratidal	major (>10)
