Habitat Type

Habitat and conservation: Pristimantis altamazonicus lives in closed-canopy primary tropical forests, and is occasionally found in flooded or secondary forests.

Activity & Microhabitat

While individuals may be found in leaf litter during the day, they are more typically found perched on low vegetation in the forest at night, where they call.

Altitudinal Range

This species occurs at an altitudinal range of 74–1,462 m (243–4,797 ft) above sea level.

Conservation Threats

Although habitat loss can be a threat to local populations, the species Pristimantis altamazonicus as a whole does not face major threats.
