The site was identified as internationally important for bird conservation in 2009 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
Pied Oystercatcher Haematopus longirostris	LC	resident (1998–2006)	6–694 birds	A4i

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Transportation and service corridors	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Energy production and mining	likely in long term (>4 years)	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
