Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,iii,iv) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Tirira, D., Boada, C. & Weksler, M.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Endangered because its extent of occurrence is less than 5,000 km², all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat and extent of occurrence and a reduction in locations.

Population:This species is rare (Tirira, in prep.). The last record known was in 1980 (D. Tirira pers. comm.)
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is poorly known. It occurs in subtropical montane and cloud forest. It is terrestrial and apparently has some affinity with water.

Threats [top]

Major Threat(s): One of the known four localities has been completely converted to urban areas. Approximately 40% of its habitat may have been destroyed (Tirira pers. comm.). Because this species has not been recorded in recent times (since 1980) there is a likelihood other populations have also been severely diminished. Survey work is urgently needed to assess the status of the species.

Conservation Actions [top]

Conservation Actions: This species is not known from any protected areas (D. Tirira pers. comm.). There is a general need to protect the habitat of this species.
