The site was identified as important in 2008 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
Horned Curassow Pauxi unicornis	CR	resident	2007	250-999 individuals	A1, A2, A3

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 (2014) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Transportation and service corridors	likely in short term (within 4 years)	majority/most of area/population (50-90%)	very rapid to severe deterioration	high

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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	medium

Year	Protected Area	Designation	% overlap with IBA
1965	Isiboro Securé	Parque Nacional y Territorio Indigena	100
1990	Isiboro Securé	Indigenous Territory	100

Habitat1	Habitat detail	% of IBA
Forest	Montane broadleaf evergreen forest, Tropical lowland evergreen forest	major (>10)
Wetlands (inland)	Rivers, Streams	-

1. IUCN Habitat classification.

Land use	% of IBA
nature conservation and research	major (>10)
agriculture	minor (<10)
