The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Black Noddy Anous minutus	LC	breeding (1996)	5,000–10,000 birds	A4i

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	Actual vs Reference (units)	% remaining	Result
Black Noddy Anous minutus	7,500 / 6,000 (pairs)	100	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (>4 years)	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	medium
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Some limited conservation initiatives are in place	very low

The islet is privately owned and protected by the landowner.
