The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Banded Quail Philortyx fasciatus	LC	resident (1995)	common	A2
Beautiful Hummingbird Calothorax pulcher	LC	resident (1995)	present	A2
Dusky Hummingbird Phaeoptila sordida	LC	resident (1995)	common	A2
Balsas Screech-owl Megascops seductus	LC	resident (1995)	common	A1, A2
Grey-breasted Woodpecker Melanerpes hypopolius	LC	resident (1995)	abundant	A2
Pileated Flycatcher Xenotriccus mexicanus	LC	resident (1995)	uncommon	A1, A2
Black-chested Sparrow Peucaea humeralis	LC	resident (1995)	common	A2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2022) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Shrubland	good (>90%)	moderate (70–90%)	moderate
Forest	good (>90%)	moderate (70–90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Invasive and other problematic species and genes	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Climate change and severe weather	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Residential and commercial development	past (and unlikely to return) and no longer limiting	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Energy production and mining	past (and unlikely to return) and no longer limiting	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Transportation and service corridors	past (and unlikely to return) and no longer limiting	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being compre­hensively and effectively implemented	high
