The site was identified as important in 2007 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
Crowned Solitary Eagle Buteogallus coronatus	EN	resident	1998-2007	common	A1
Hyacinth Macaw Anodorhynchus hyacinthinus	VU	unknown	1998-2007	present	A1
Russet-mantled Foliage-gleaner Syndactyla dimidiata	LC	resident	1998-2007	rare	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2011) 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
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible

Year	Protected Area	Designation	% overlap with IBA
2007	Tagatiya-mi	Reserva Natural - Privado	3
2014	Guayacan I II III	Reserva Natural - Privado	4

Habitat1	Habitat detail	% of IBA

Savanna	Cerrado	8
