 The home range of the Namib Desert Horse reaches north in the Namib Desert to the Koichab River, usually dry, and west to the Great Escarpment. Bands of horses range together, consisting of as few as two animals, although there are generally more. In observations between 1993 and 2003, between six and eleven bands were identified, including a mixture of bachelor herds, breeding groups and co-operating stallion groups (groups with more than one stallion that share breeding duties). The Namib Desert Horse travels extensively, searching for food, water and shelter from the climate and insects. A 1994 study found that they have an average home range of 13 square miles (34 km2), although not all of that is traversed each day. They must cover considerable distances, as much as 15 to 20 kilometres (9 to 12 mi) between the few existing water sources and the best grazing sources. This creates severe selection pressure and removes weak animals from the population.
