Desert elephants or desert-adapted elephants are not a distinct species of elephant but are African bush elephants (Loxodonta africana) that have made their homes in the Namib and Sahara deserts in Africa. Previously they were classified as a subspecies of the African bush elephant, but this is no longer the case. Desert-dwelling elephants were once more widespread in Africa than they are at present; they are currently found only in Namibia and Mali. They tend to migrate from one waterhole to another following traditional routes which depend on the seasonal availability of food and water. They face being threatened by poaching and from changes in land use by humans.
