The site was identified as internationally important for bird conservation in 2020 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 Skimmer Rynchops niger	LC	non-breeding (2016–2020)	230–3,300 birds	A4
Elegant Tern Thalasseus elegans	NT	non-breeding (2016–2020)	178 birds	B1a

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2014) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Geological events	past (and unlikely to return) and no longer limiting	whole of popul­ation/area (>90%)	moderate decline (10–30% 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 plan exists, but the management planning process has begun	Very little or no conservation action taking place	very low

Habitat	% of IBA	Habitat detail
Marine Intertidal	major (>10)
Marine Neritic	major (>10)
