Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-08-19
Assessor(s): Granjon, L.
Reviewer(s): Amori, G.
Listed as Least Concern in view of its wide distribution, 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.

Geographic Range [top]

Range Description:

The species is mostly a sub-Saharan species although it occurs in the Arabian Peninsula, where it may have been introduced by man, and has been recorded across the Sahara, but it is mostly extinct there. This species is widespread in savannas in Africa, found from South Mauritania and Senegal across the Sahel to Sudan and Ethiopia, from here it ranges southwards to Uganda and central Kenya. Its presence in central Tanzania and Zambia is uncertain. The species is found along the Nile Valley where its distribution is restricted to a narrow strip of flooded plain. It has additionally been recorded from at least three isolated Saharan mountain ranges. In Ethiopia it is not found above 1,600 m asl.

Habitat and Ecology [top]

Habitat and Ecology:

This species favours grasslands, savanna, and shrublands. It is also a commensal species that is very common close to villages and other modified habitats.

They live less than one year in nature; litter size is 6 youngs and gestation time is 21-23 days.


Threats [top]

Major Threat(s): There are no major threats to this species.

Conservation Actions [top]

Conservation Actions:

There are no conservation measures in place; probably present in the majority of protected areas in the distribution zone - such as Zakouma National Park, Chad (Granjon et al. 2004). Further studies are needed into the taxonomy, distribution, abundance, reproduction and ecology of this species.
