Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2015
Date Assessed: 2015-06-25
Assessor(s): Carmignotto, A.P., Solari, S., de la Sancha, N. & Costa, L.
Reviewer(s): Martin, G.M.
This species is listed as Least Concern in because of its wide distribution, presumed large population, tolerance of some degree of habitat modification, occurrence in a number of protected areas and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Habitat and Ecology [top]

Habitat and Ecology:This species is nocturnal and arboreal, frequents the forest understory, where it uses slender branches and vines. It is found in evergreen and gallery forests (Emmons and Feer 1997). It is a characteristic inhabitant of the gallery forests of southern South America but has broad habitat tolerance. It has been caught under fallen trunks, in tree holes, and in moist woodland. It is reported to be an adept climber, and nests made of vegetation have been found 1.6 m off the ground. One such nest contained seven individuals. In eastern Paraguay it has usually been captured on vegetation but sometimes has been caught on the ground as well. This marsupial is found throughout the Brazilian cerrado, usually associated with mesic areas such as gallery forests. The species is reported to have up to twelve young, females lack a true pouch, and the teats remain hidden when the female is not lactating (Nitikman and Mares 1987).

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): There are no major threats. In some areas, especially along the Andean foothills, this species is declining due to deforestation.

Conservation Actions [top]

Conservation Actions: This species occurs in protected areas. Further research is needed on the distribution of this species and effects of possible threats.
