Geography comments: "in the lower Japurá River region... within the Amanã Sustainable Development Reserve"
Habitat: tropical/subtropical moist broadleaf forest
Protection: other protected area
Substrate: ground surface
Disturbance: agriculture, hunting
MAP: 2500.0
Habitat comments: "tropical and humid, with annual rainfall of about 2, 500 mm unevenly distributed over the year... with a dry season from July to December... The region remains little disturbed by human activities, although about 4, 000 persons live in 23 communities within the ASDR... They depend primarily on small-scale agriculture (e.g., cassava, banana, and corn) and fishig, but there is also some subsistence hunting and collection of nuts and fruits from forest trees"
