Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2016
Date Assessed: 2016-08-12

Listed as Data Deficient in view of the little information about its distribution, abundance, or habitat preferences The habitat between the two areas is thought to be continuous and potentially favourable. The species is not abundant when trapping, but evidence of the species is found in owl pellets. It may be that the species is more common than thought and it is just the trapping techniques used that are unsuitable for catching this species.
Previously published Red List assessments:

Geographic Range [top]

Range Description:Published records for this species are from southwestern Kenya, northern Tanzania and Rwanda. The Rwanda records are from owl pellets (six to seven specimens). It has been recorded at 1,020 and 1,090 m asl (Stanley et al. 2007).
Countries occurrence:
Kenya; Rwanda; Tanzania, United Republic of

Population [top]

Population:It is known from very few specimens, and from the low trapping success, it appears to be uncommon to rare, however, this may be an artefact of the methodology used.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is found in moist savanna. It has been recorded in wooded grassland (Stanley et al. 2007). This does not appear to be a commensal species.

Threats [top]

Major Threat(s): The habitat is being fragmented, but not enough to consider this a major threat. Likewise, fire is part of the natural cycle and not a major threat (one of the areas where this species was recorded was burnt, completely transforming the habitat and the fauna).

Conservation Actions [top]

Conservation Actions: The species has been recorded in Tarangire National Park in Tanzania (Stanley et al. 2007).
