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
Lesser Frigatebird Fregata ariel	LC	resident (1982)	2,000–5,700 pairs	A4ii
Brown Booby Sula leucogaster	LC	resident (1972–1993)	1,500–8,500 pairs	A4ii
Red-necked Stint Calidris ruficollis	NT	non-breeding (2004)	4,107 birds	A4i
Grey-tailed Tattler Tringa brevipes	LC	non-breeding (2004)	5,489 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
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

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