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
Herald Petrel Pterodroma heraldica	LC	breeding	1975	800-1,200 breeding pairs	A4ii
Phoenix Petrel Pterodroma alba	VU	breeding	1989	10-99 breeding pairs	A1, A4ii
Tropical Shearwater Puffinus bailloni	LC	breeding	1971-1975	2,500-9,999 breeding pairs	A4ii
Sooty Tern Onychoprion fuscatus	LC	breeding	-	500,000 individuals	A4i
A4iii Species group - waterbirds	n/a	breeding	-	500,250 individuals	A4iii

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
Herald Petrel Pterodroma heraldica	1,000	1,000	breeding pairs	100	not assessed
Phoenix Petrel Pterodroma alba	55	55	breeding pairs	100	not assessed
Puffinus lherminieri	1,500	1,500	breeding pairs	100	not assessed
A4iii Species group - waterbirds	500,000	500,000	individuals	100	not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	no or imperceptible deterioration	low
Biological resource use	happening now	some of area/population (10-49%)	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
