The site was identified as internationally important for bird conservation in 2007 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
Nuku Hiva Imperial Pigeon Ducula galeata	EN	resident (2006)	35 birds	A1, A2
White-capped Fruit-dove Ptilinopus dupetithouarsii	LC	resident (-)	common	A2
Polynesian Swiftlet Aerodramus leucophaeus	LC	resident (-)	common	A2
Ultramarine Lorikeet Vini ultramarina	CR	resident (-)	2,300 birds	A1, A2
Iphis Monarch Pomarea iphis	CR	resident (1998)	500–1,250 pairs	A1, A2
Northern Marquesan Reed-warbler Acrocephalus percernis	LC	resident (-)	common	A2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2006) 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	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
