Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Butynski, T.M., De Jong, Y. & Bearder, S.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Listed as Least Concern as this species is widespread and fairly common (even abundant) and there are currently no major threats resulting in a significant population decline.

Geographic Range [top]

Range Description:This species is present in Ethiopia, Kenya and Somalia (may extend into north-eastern Uganda and possibly south-eastern Sudan, but no confirmed records as yet). It is distributed between the Webi Shebeli River valley in the north-east and the Tana River valley in the south-west, towards Lake Turkana (at least as west as South Horr) and the Ethiopian Rift Valley in the north-west. The species distribution limits in the Ogaden area are not certain. It has a known altitudinal range of 150 to 1,200 m asl (see Butynski and De Jong 2004). Narrowly sympatric with Galago senegalensis in Meru National Park, Kenya (Butynski and De Jong 2004).

Population [top]

Population:It is patchily distributed, but locally common, throughout its range. Over much of the range, the density is probably less than one animal per hectare, but densities are much higher at some sites (e.g., >4 animals per ha in Meru N.P.; Butynski and De Jong 2004).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a nocturnal, arboreal species living in drier, thornier habitat than any other galago, or indeed any other African primate. It may be found in all strata within Acacia-Commiphora deciduous bushland and thicket. It is absent from open woodland and bushland. It can be found in Acacia dominant bushland and thicket in severely degraded habitat. This species is either solitary or found in small groups. There is no information available on reproduction in this species, but it is likely that a single infant is born.

Threats [top]

Major Threat(s): A number of subpopulations in Somalia may be threatened by habitat loss or degradation. However, this species has been recorded in severely degraded habitat (through overgrazing; Butynski and De Jong 2004).

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of CITES. It has been recorded from the Meru and Shaba National Parks and Arawale National Reserve, Kenya (Butynski and De Jong 2004). Further studies into the geographic distribution, taxonomy and ecology of this species are needed.
