The site was identified as internationally important for bird conservation in 2007 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
Brushland Tinamou Nothoprocta cinerascens	LC	resident (-)	present	A3
Quebracho Crested Tinamou Eudromia formosa	LC	resident (-)	present	A3
Chaco Chachalaca Ortalis canicollis	LC	resident (-)	present	A3
Chaco Owl Strix chacoensis	NT	resident (-)	present	A3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2011) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	poor (40–69%)	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	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Natural system modifications	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high

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	Very little or no conservation action taking place	very low

Habitat	% of IBA	Habitat detail
Forest	67	Tropical deciduous forest
Shrubland	6	Scrub
