The site was identified as important in 2010 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
Chilean Pigeon Patagioenas araucana	LC	resident	2009	abundant	A2, A3
Magellanic Woodpecker Campephilus magellanicus	LC	resident	2009	present	A3
Austral Parakeet Enicognathus ferrugineus	LC	breeding	2009	present	A3
Black-throated Huet-huet Pteroptochos tarnii	LC	resident	2009	present	A2, A3

White-throated Treerunner Pygarrhichas albogularis	LC	resident	2009	present	A3
Thorn-tailed Rayadito Aphrastura spinicauda	LC	resident	2009	present	A3
Des Murs's Wiretail Sylviorthorhynchus desmurii	LC	resident	2009	present	A3
Patagonian Tyrant Colorhamphus parvirostris	LC	resident	2009	present	A3
Fire-eyed Diucon Xolmis pyrope	LC	resident	2009	present	A3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2010).
