The site was identified as internationally important for bird conservation in 2010 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
Chilean Woodstar Eulidia yarrellii	CR	resident (2008)	present	A1, A2, A3
Slender-billed Finch Xenospingus concolor	NT	resident (2008)	present	A1, A2, A3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	-	poor (40–69%)	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	high
Pollution	past (and unlikely to return) and no longer limiting	whole of popul­ation/area (>90%)	slow decline (1–10% 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	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	low

Habitat	% of IBA	Habitat detail
