|Scientific Name:||Phacochoerus aethiopicus|
|Species Authority:||(Pallas, 1766)|
|Taxonomic Notes:||There are two described subspecies, one (the nominate form) extinct since about 1871. P. a. delamerei survives in the northern part of the range in the Horn of Africa.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor/s:||d'Huart, J.P., Butynski, T.M. & De Jong, Y.|
|Reviewer/s:||Leus, K. & Hoffmann, M.|
Listed as Least Concern as the species is relatively widespread, abundant, and there are no major threats believed to be resulting in a significant population decline. In addition, it is suspected that this species may be more widespread than presently known.
|Range Description:||Presently known only from south-eastern Ethiopia, western Somalia, and in central and eastern Kenya (d'Huart and Grubb 2001). More recently, the range has been found to extend southwards to Tsavo West National Park, west of Athi River and south of the Galana River (Culverwell et al. 2008, de Jong et al. 2009), and northwards, towards Melka Mari National Park (Obanda et al. in press). Formerly occurred in South Africa, in the south-eastern parts of the former Cape Province and apparently adjacent parts of KwaZulu-Natal, but long since extinct there (d'Huart and Grubb 2001, Grubb and d'Huart 2010). Most records are from near sea level to ca 1,400 m asl (Central Kenya).|

|Population:||The Desert Warthog is generally reported as being locally abundant (Grubb and d'Huart 2010), mostly near small and remote villages or lodges where there is water (T. Butynski, Y. de Jong, J. Culverwell, and J. King pers. comm.). In Ethiopia, they are common in the whole Ogaden region and can be observed both in family sounders in bushy areas and in larger aggregations of up to 30 individuals around permanent wells and close to towns (Wilhelmi et al. 2004). Nevertheless, there are large areas within the geographic range from which the species is absent.|
|Habitat and Ecology:||The Desert Warthog inhabits open arid regions, in vegetation types ranging from xerophylous bush and open woodland to subdesert steppe. They prefer plains on predominantly sandy soils, and avoid hilly terrain. Desert Warthogs are dependent on occurrence of water and shade (Grubb and d'Huart 2010; T. Butynski, Y. de Jong and J. Culverwell pers. comm.).|
|Major Threat(s):||There are no major threats to the species. However, they may be subject to localized incidences of hunting for bushmeat trade (e.g. Wilhelmi et al. 2004). Habitat degradation due to over-grazing by domestic livestock and competition for water with humans and domestic livestock may be affecting populations of Desert Warthog in some regions, but this needs investigation (T. Butynski and Y. de Jong pers. comm.)|
The Desert Warthog occurs in a number of protected areas, including Tsavo West and Tsavo East National Parks (Kenya), Samburu, Buffalo Springs, Shaba, and Dodori National Reserves (Kenya), and likely in the Babile and Yabelo Wildlife Sanctuaries and associated Controlled Hunting Areas in Ethiopia and Meru and Kora National Parks in Kenya (d'Huart and Grubb 2001; Grubb and d'Huart 2010; T. Butynski and Y. de Jong pers. comm.).
This is a largely unstudied species for which further field surveys are needed to better determine geographic limits, area of occupancy, abundance and the impacts of various human/livestock-raising activities on distribution and abundance. Information on habitat preference and habitat limits are also needed, as is a good study of the basic ecology and behaviour of this species.
