The Hoanib is one of the 12 ephemeral seasonal rivers in the west of Namibia, where it used to be the border between northern Damaraland and Kaokoland. Its length is 270 km. With the low population density in the area, the oasis character of the river valley and the relatively high wildlife population of the Hoanib, like in the case of the Hoarusib, its valley is one of the last true wilderness areas in Namibia. One of the last settlements of desert elephants, it is characterised by strong wind and water eroded, weathered stone deposits. Inflows of Hoanib are Aap River, Otjitaimo River, Ombonde, Ganamub, Mudorib and Tsuxub.
Desert elephants or desert-adapted elephants are not a distinct species of elephant but are African bush elephants 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.
