Assessment Information

Red List Category & Criteria: DD    ver 3.1 (2001)
Year Assessed: 2004
Assessor/s: Waldemarin, H.F.
Evaluator/s: Hussain, S.A. & Reuther, C. (Otter Red List Authority)
Justification: The species has an apparent wide distribution along the original range, but there are no systematic studies to evaluate the size of populations and there is no standardised information about changes in the extent of occurrence or area of occupancy. So there is no information about population size (Criteria A), number of mature animals (Criteria C and D) or quantitative analysis (Criteria E). Current geographic range appears to be similar to the historic range.
