IBA Justification

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'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
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

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2022).
