The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
White-capped Fruit-dove Ptilinopus dupetithouarsii	LC	resident	-	common	A2
Ultramarine Lorikeet Vini ultramarina	CR	resident	1997	51 individuals	A1, A2
Fatu Hiva Monarch Pomarea whitneyi	CR	resident	-	200-300 breeding pairs	A1, A2
Southern Marquesan Reed-warbler Acrocephalus mendanae	LC	resident	-	common	A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2018) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Fatu Hiva Monarch Pomarea whitneyi	300	30	mature individuals	10	very 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%)	very rapid to severe deterioration	very high
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Natural system modifications	likely in long term (beyond 4 years)	some of area/population (10-49%)	very rapid to severe 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10%)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low

Habitat1	Habitat detail	% of IBA
Marine Coastal/Supratidal		minor (<10)
Marine Intertidal		minor (<10)
Forest	Dry deciduous forest (tropical), Lower montane rain forest (tropical), Lowland evergreen rain forest (tropical)	-
Shrubland		-
