The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Yellow-eyed Penguin Megadyptes antipodes	EN	resident	-	present	A1
Stewart Island Shag Leucocarbo chalconotus	VU	breeding	1955-2011	435-1,100 individuals	A1, A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2014) may differ.

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 (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
1965	Pig Island	Scenic Reserve	-

Habitat1	Habitat detail	% of IBA
Introduced vegetation		major (>10)
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)
