Habitat and Ecology [top]

Habitat and Ecology: This species has been captured in grassy paramo, in shrubby paramo/forest ecotone or in grassy glades surrounded by forest, and in deep inside Subalpine Rain Forest. Most recorded captures were on the ground, on special rabbit trails or runways through dense grass or low herbs, and along the wet margins of small streams. Other muroid species that were trapped syntopically (in the same habitats) with T. ucucha include Akodon latebricola, Akodon mollis, Anotomys leander, Chilomys instans, Microryzomys altissimus, M. minutus, Neusticomys monticolus, T. aureus, T. baeops, T. cinnameus, T. erro, and T. paramorum (Voss, 2003).
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threats are deforestation, fragmentation, and agriculture.
