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
Atoll Fruit-dove Ptilinopus coralensis	NT	resident	-	frequent	A1, A2
Gygis alba	NR	breeding	2003	min 1,000 breeding pairs	A4i
Tuamotu Kingfisher Todiramphus gambieri	CR	resident	-	120-150 individuals	A1, A2
Tuamotu Reed-warbler Acrocephalus atyphus	LC	resident	-	frequent	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 (2012) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Gygis alba	1,000	1,000	breeding pairs	100	not assessed
Tuamotu Kingfisher Todiramphus gambieri	135	135	individuals	100	not assessed

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%)	slow but significant deterioration	high
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	whole area/population (>90%)	no or imperceptible deterioration	low

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%)	No management planning has taken place	Very little or no conservation action taking place	negligible

Habitat1	Habitat detail	% of IBA
Forest	Dry deciduous forest (tropical)	55
Artificial/Terrestrial	Coconut plantations	25
Shrubland		10
Marine Coastal/Supratidal		minor (<10)
Marine Intertidal		minor (<10)
Marine Neritic		minor (<10)
