The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Masatierra Petrel Pterodroma defilippiana	VU	breeding (-)	10,000-19,999 birds	A1, A4
Masatierra Petrel Pterodroma defilippiana	VU	breeding (2015–2021)	min 1,500 birds	A1, A4

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. The most recent assessment (2014) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	very low

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