The site was identified as important in 2012 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
Collared Petrel Pterodroma brevipes	VU	breeding	1984	165 individuals	A1, A4ii
Fiji Petrel Pseudobulweria macgillivrayi	CR	breeding	2005	< 50 individuals	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2012) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2012) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Neritic	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Climate change and severe weather	likely in long term (beyond 4 years)	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
Whole area of site (>90%) covered by appropriate conservation designation	No management planning has taken place	Very little or no conservation action taking place	low

Year	Protected Area	Designation	% overlap with IBA
