Geography comments: "Camera trap sites were set around the periphery of Isla Alta"

Environment
Habitat: tropical/subtropical dry broadleaf forest

Protection: unprotected

Substrate: ground surface

Disturbance: grazing, hunting, selective logging

Habitat comments: "The natural vegetation of the study area is typical of the transition zone between UPAF and the humid Chaco ecosystem to the west... The UPAF in this area is a dense, semideciduous, subtropical forest intermixed with patches of natural grassland... All camera trap sites were under complete forest cover and set to monitor a cattle, wildlife, or human trail on the private property of a community member of Isla Alta... Most of the private forested properties around Isla Alta are used to range a small amount of cattle throughout the year. Many residents also selectively harvest native trees for lumber, firewood, or charcoal production according to personal or financial need. Frequent hunting/ trapping occurs around Isla Alta"
