Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2008
Assessor/s:	Dunnum, J., Vargas, J., Bernal, N., Pardinas, U., Patterson, B. & Teta, P.
Reviewer/s:	Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Contributor/s:
Justification: Listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, has a tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population [top]

Population:	It is often common (Emmons and Feer, 1997).
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	This mouse is arboreal, solitary and has nocturnal activity. It is found in mature and secondary rainforest, dry forest, savanna, scrub, gardens and plantations. It feeds on fruit and green seeds and uses all levels of the forest, including occasionally the ground. It is most numerous in dense viny vegetation. It nests in tree holes, in dense masses of vines or epiphytes, and among palm leaves. It often invades houses in the forest and seems particularly fond of thatched roofs (Emmons and Feer, 1997).
Systems:	Terrestrial
