The site was identified as important in 2022 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
Macaroni Penguin Eudyptes chrysolophus	VU	breeding	2015-2021	min 150 individuals	A1
Macaroni Penguin Eudyptes chrysolophus	VU	breeding	2007	35,000 breeding pairs	A1
Southern Rockhopper Penguin Eudyptes chrysocome	VU	breeding	2015-2021	min 500 individuals	A1
Southern Rockhopper Penguin Eudyptes chrysocome	VU	breeding	2006-2007	134,000 breeding pairs	A1, A2, A4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2022) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. The most recent assessment (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	-	good (> 90%)	favourable
Grassland	-	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	past (and unlikely to return) and no longer limiting	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
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
