The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Brown Booby Sula leucogaster	LC	resident (1982–2006)	18,000 pairs	A4ii
Roseate Tern Sterna dougallii	LC	non-breeding (1998–2006)	20,000 birds	A4i

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low
Invasive and other problematic species and genes	likely in long term (>4 years)	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low

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