Current view: Data table and detailed info

IBA Justification

The site was identified as internationally important for bird conservation in 2006 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 List	Season (year[s] of estimate)	Size	IBA criteria
Brazilian Merganser Mergus octosetaceus	CR	resident (-)	< 50 birds	A1
Crowned Solitary Eagle Buteogallus coronatus	EN	resident (-)	present	A1
Sharp-tailed Tyrant Culicivora caudacuta	LC	resident (-)	30 birds	A1

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2022) is shown below.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2022	very poor	very high	very low
Whole site assessed?	State assessed by	Accuracy of information
yes	habitat	poor

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	moderate (70–90%)	very poor (<40%)	very poor
Savanna	very poor (<40%)	poor (40–69%)	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	whole of population/area (>90%)	rapid decline (>30% over 3 generations)	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	very low
