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
Eared Quetzal Euptilotis neoxenus	LC	resident	1995	present	A1
Thick-billed Parrot Rhynchopsitta pachyrhyncha	EN	resident	1995	present	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 (2023) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Biological resource use	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Natural system modifications	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	No management plan exists but the management planning process has begun	Very little or no conservation action taking place	low
