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
Black-capped Vireo Vireo atricapilla	NT	breeding	1989	28 breeding pairs	A1
Cassin's Finch Haemorhous cassinii	LC	winter	1995	uncommon	A1
Colima Warbler Leiothlypis crissalis	LC	breeding	1995	uncommon	A1, A2

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 (2023) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Natural system modifications	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Energy production and mining	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Invasive and other problematic species and genes	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	No management plan exists but the management planning process has begun	The conservation measures needed for the site are being comprehensively and effectively implemented	medium

Year	Protected Area	Designation	% overlap with IBA
2002	Cuenca Alimentadora del Distrito Nacional de Riego 004 Don Martín	Área de Protección de los Recursos Naturales	82

Habitat1	Habitat detail	% of IBA
Forest	Pine-oak, Pine, Tropical coniferous	68
Shrubland	Second-growth & disturbed scrub, Scrub, Arid montane scrub	21
Savanna		9
Other		minor (<10)

1. IUCN Habitat classification.

Tenencia de la tierra: Privada.
