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
Masatierra Petrel Pterodroma defilippiana	VU	breeding	-	10,000-19,999 individuals	A1, A4
Masatierra Petrel Pterodroma defilippiana	VU	breeding	2015-2021	min 1,500 individuals	A1, 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 (2014) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	happening now	whole area/population (>90%)	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

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