Scientific Name: Oligoryzomys destructor (Tschudi, 1844)
Common Name(s):
English Destructive Pygmy Rice Rat
Oryzomys spodiurus (Tschudi, 1844)
Taxonomic Notes: Musser and Carleton (2005) state that distributional limits, validity of included synonyms, and relationships to other Andean species all require detailed investigation. In Argentina further taxonomical research is needed.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-08-20
Assessor(s): Weksler, M., Tirira, D., Zeballos, H., Bernal, N., Vargas, J., Vivar, E. & Jayat, J.P.
Reviewer(s): Amori, G.
This species is listed as Least Concern in view of its wide distribution, presumed large population, it occurs 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.

Population [top]

Population:It is locally common to uncommon.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in tropical, subtropical and montane forest; also it occurs close to paramo (Barnet, 1999). Most of the Bolivian records are from the Yungas Forest (Anderson 1997; Musser and Carleton, 2005).
Generation Length (years):1-2

Threats [top]

Major Threat(s): Deforestation and habitat lost are affecting the species although they are not a major threat (M. Weksler and D. Tirira pers. comm.).

Conservation Actions [top]

Conservation Actions: This species occurs in a number of protected areas throughout its range.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
