IBA Justification

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'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Nukuhiva Imperial-pigeon Ducula galeata EN resident 2006 35 individuals 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 individuals A1, A2
Iphis Monarch Pomarea iphis CR resident 1998 500-1,250 breeding pairs A1, A2
Northern Marquesan Reed-warbler Acrocephalus percernis LC resident - common A2

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2007).
