Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Emmons, L. & Helgen, K.
Reviewer(s): Duckworth, J.W. (Small Carnivore Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern in light of its large range in Amazonian forests, presumed large populations remaining in forested habitat and although it may be declining in portions of its range, not at a rate sufficient to be considered threatened. This species is a candidate for a Data Deficient listing, as almost nothing is known of its ecology, threats and distribution, however, it is suspected to occur over a large area of relatively intact habitat which suggests that it is not currently declining at a rate sufficient to qualify for listing. More research effort is needed to confirm it estimated distribution presence in protected areas and if it can tolerate human disturbance.
Previously published Red List assessments:
1996 Data Deficient (DD)
1994 Indeterminate (I)

Geographic Range [top]

Range Description: The species is distributed in the Amazon Basin in Brazil, Ecuador, Peru, southern Colombia and northern Bolivia. The limits of the range are poorly know as so few specimens have been described.

Population [top]

Population: Nothing is known of the populations of this species as it is seldom encountered even where it is known to occur.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: The Amazon weasel has been reported mainly from humid riparian forests (Izor and De la Torre, 1978).
Systems: Terrestrial

Threats [top]

Major Threat(s): Almost nothing is known of the threats to this species, although it could be inferred that habitat conversion of the Amazonian rain forests is a threat in some portions of its range.

Conservation Actions [top]

Conservation Actions: Schreiber et al. (1989) affirm that the tropical weasel may occur in several of the large national parks of Amazonia. It has been reported to occur in the Tambopata Reserve Zone (Emmons pers. comm), and unconfired reports exist from Cocha Cashu and Alto Purus (Emmons pers. comm).
