The site was identified as important in 2021 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:

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2021) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2022) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	poor (40-69%)	poor (40-69%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Climate change and severe weather	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Agricultural expansion and intensification	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	past (and unlikely to return) and no longer limiting	whole area/population (>90%)	very rapid to severe deterioration	low
Residential and commercial development	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible 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
2001	Ing. Gerardo Cruickshank García	Parque Estatal	5

Habitat1	Habitat detail	% of IBA
Wetlands (inland)	Water-fringe vegetation	33

1. IUCN Habitat classification.

Land use	% of IBA
urban/industrial/transport	15
agriculture	9
