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
Yellow-eyed Penguin Megadyptes antipodes	EN	resident (-)	present	A1
Stewart Island Shag Leucocarbo chalconotus	VU	breeding (1955–2011)	435–1,100 birds	A1, A4i

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2014) 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	likely in long term (>4 years)	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

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
1965	Pig Island	Scenic Reserve (III)	-

Habitat	% of IBA	Habitat detail
Introduced vegetation	major (>10)
Marine Coastal/Supratidal	major (>10)
