The site was identified as internationally important for bird conservation in 2014 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
Campbell Teal Anas nesiotis	VU	resident (-)	50-249 birds	A1, A4i

Erect-crested Penguin Eudyptes sclateri	EN	non-breeding (1942–2012)	20–30 birds	A1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	past (and unlikely to return) and no longer limiting	whole of popul­ation/area (>90%)	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
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation (management category)	% coverage of IBA
