The site was identified as important in 2024 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
Greater Rhea Rhea americana	NT	resident	2015	min 30 males	B1a
Mottled Piculet Picumnus nebulosus	NT	resident	2017	min 30 individuals	B1a

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2024) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2024. The most recent assessment (2024) 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
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Habitat1	Habitat detail	% of IBA
Wetlands (inland)		major (>10)
Forest		minor (<10)
