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
Fiordland Penguin Eudyptes pachyrhynchus	NT	breeding	1995-2014	76-126 nests	A1, A4ii

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	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low

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
1978	Fiordland National Park	National Park	18
1987	Pyke Forest	Stewardship Area	56
1990	Te Wahipounamu – South West New Zealand	World Heritage Site (natural or mixed)	9

Habitat1	Habitat detail	% of IBA
Forest		major (>10)
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)
Shrubland		major (>10)
Wetlands (inland)		minor (<10)
