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 (2019) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Residential and commercial development	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low

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 planning has taken place	Very little or no conservation action taking place	negligible

Year	Protected Area	Designation	% overlap with IBA
1983	Bañados del Río Dulce y Laguna Mar Chiquita	Provincial Multiple Use Reserve	100
1994	Bañados del Río Dulce y Laguna de Mar Chiquita	Reserva Provincial de Uso Múltiple	67
2002	Bañados del Río Dulce y Laguna de Mar Chiquita	Ramsar Site, Wetland of International Importance	75
