Animalia Chordata Mammalia Rodentia Cricetidae

Scientific Name: Oligoryzomys destructor
Species Authority: (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: 2008
Date Assessed: 2008-06-30
Assessor(s): Weksler, M., Tirira, D., Zeballos, H., Bernal, N., Vargas, J., Vivar, E. & Jayat, J.P.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
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.
Previously published Red List assessments:
2000 Data Deficient (DD)
1996 Lower Risk/least concern (LR/lc)
1996 Data Deficient (DD)
