The site was identified as important in 2008 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
Straight-billed Reedhaunter Limnoctites rectirostris	NT	resident	1992-2006	90 individuals	A1, A2
Black-and-white Monjita Xolmis dominicanus	VU	resident	1992-2006	90 individuals	A1
Saffron-cowled Blackbird Xanthopsar flavus	EN	resident	1986	90 individuals	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2008) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2013) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Energy production and mining	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high

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 plan exists but the management planning process has begun	Unknown	negligible

Year	Protected Area	Designation	% overlap with IBA
1986	Quebrada de los Cuervos	Protected Natural Area	<1
1986	Quebrada de los Cuervos	Municipal Reserve	<1
2008	Quebrada de los Cuervos	Paisaje Protegido	4

Habitat1	Habitat detail	% of IBA
Forest		major (>10)
