The site was identified as important in 2021 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
Red-legged Cormorant Poikilocarbo gaimardi	NT	resident	2016-2021	500-800 individuals	A4, B1a, B3a

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2021) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2021) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	happening now	small area/few individuals (<10%)	slow but significant 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
