Robust Tuco-tuco

Assessment Information [top]

Red List Category & Criteria:

Data Deficient ver 3.1

Year Assessed:

2008

Assessor/s:

Bidau, C., Lessa, E. & Ojeda, R.

Reviewer/s:

Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)

Justification:
Listed as Data Deficient due to continuing uncertainty on the species distribution, threats and conservation measures. This species is suspected to be threatened, however, there is still very little information on its extent of occurrence, status and ecological requirement; thus it is not possible to assess the species against criteria for threat. Further taxonomic information may change species status in the future.

History:

1996
