Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-06-10
Assessor(s): Lavrenchenko, L. & Schlitter, D.
Reviewer(s): Amori, G.
Listed as Least Concern in view of its wide distribution, the fact that it appears to have a tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population [top]

Population:Only 34 specimens are known, and it appears to be a very rare species. During extensive collecting from 1968 to 1998, Yalden found no specimens in samples totalling over 6,300 rodents. Muller trapped a few in houses in Simien, but it was not recorded in more recent trapping there. Very extensive trapping in the Bale Mountains has failed to record it. Duane Schlitter (pers. comm.) has only ever trapped one in highly grazed grasslands north of Addis Ababa.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is typically found in upland grasslands, however, it has also been reported as commensal in Simien. It is presumed to be a nocturnal, granivorous species. However, if the species is insectivorous, it may explain the lack of trap records. The dentition of this species indicates that they may dig their own burrows.
Generation Length (years):1-2

Threats [top]

Major Threat(s): The quality of the habitat may have been affected by conversion to agricultural use (the area is heavily populated and used by farmers), and it is suggested that this species may have declined as a result (it is thought to have become less common in the last 50 years).

Conservation Actions [top]

Conservation Actions: This species is present within the area of the Simien Mountains National Park and Arsi Mountains National Park, Ethiopia.
