The site was identified as important in 2022 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 Swift Cypseloides niger	VU	breeding	2021	36 individuals	A1
Rufous Hummingbird Selasphorus rufus	NT	winter	2018	46 individuals	B1a
Thick-billed Parrot Rhynchopsitta pachyrhyncha	EN	resident	2020	186 individuals	A1, A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2022) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. 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%)	good (> 90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	likely in short term (within 4 years)	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
Invasive and other problematic species and genes	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
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	No management plan exists but the management planning process has begun	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
2004	Ejido El Palmito	Zona de Preservación Ecológica de los Centros de Población	2
2008	Quebrada de Santa Bárbara	Area de Proteccion de Recursos Naturales	<1
