African Wild Ass Totally Explained

Everything about The African Wild Ass totally explained

The African Wild Ass (Equus africanus) is a wild member of the horse family, Equidae. This species is believed to be the ancestor of the domestic donkey which is usually placed within the same species. The species name for the African Wild Ass is sometimes designated as, asinus, from the domestic. They live in the deserts and other arid areas of northeastern Africa, in Eritrea, Ethiopia and Somalia; it formerly had a wider range north and west into Sudan, Egypt and Libya. About 570 individuals exist in the wild.

Description

The African Wild Ass is 2 m long and 1.25 - 1.45 m tall at the shoulders, with a tail 30-50 cm long. It weighs between 230-275 kg. The short, smooth coat is a light grey to fawn colour, fading quickly to white on the undersides and legs. There is a slender, dark dorsal stripe in all subspecies, while in the Nubian Wild Ass E. a. africanus, as well as the domestic donkey, there's a stripe across the shoulder. The legs of the Somali Wild Ass E. a. somalicus are horizontally striped with black, resembling those of a zebra. On the nape of the neck there's a stiff, upright mane, the hairs of which are tipped with black. The ears are large with black margins. The tail terminates with a black brush. The hooves are slender and approximately the diameter of the legs.

Habitat

African Wild Asses are well suited to life in a desert or semi-desert environment. They have tough digestive systems, which can break down desert vegetation and extract moisture from food efficiently. They can also go without water for a fairly long time. Their large ears give them an excellent sense of hearing and help in cooling. Because of the sparse vegetation in their environment wild asses live somewhat separated from each other (except for mothers and young), unlike the tightly grouped herds of wild horses. They have very loud voices, which can be heard for over 3 km (2 miles), which helps them to keep in contact with other asses over the wide spaces of the desert.

Behavior

The African Wild Ass is primarily active in the cooler hours between late afternoon and early morning, seeking shade and shelter amongst the rocky hills during the day. Swift and sure-footed in their rough, rocky habitat, the African Wild Ass has been clocked at 50 km/h (30 mph). Mature males defend large territories around 23 square kilometers in size, marking them with dung heaps - an essential marker in the flat, monotonous terrain. Due to the size of these ranges, the dominant male can't exclude other males. Rather, intruders are tolerated - recognized and treated as subordinates, and kept as far away as possible from any of the resident females. In the presence of estrous females the males bray loudly. These animals live in loose herds of up to fifty individuals.
Wild asses can run swiftly, almost as fast as a horse. However, unlike most hoofed mammals, their tendency is to not flee right away from a potentially dangerous situation, but to investigate first before deciding what to do. When they need to they can defend themselves with kicks from both their front and hind legs. Equids were used in ancient Sumer to pull wagons circa 2600 BC, and then chariots on the Standard of Ur, circa 2000 BC. These have been suggested to represent onagers, but are now thought to have been domestic asses. (Clutton-Brock)

Diet

The African Wild Asses' diet consists of grasses, bark, and leaves. Despite being primarily adapted for living in an arid climate, African Wild Asses are dependent on water, and when not receiving the needed moisture from vegetation they must drink at least once every three days. However, they can survive on a surprisingly small amount of liquid, and have been reported to drink salty or brackish water.

Conservation Status

Though the species itself is under no threat of extinction, due to abundant domestic stock (Donkey and Burros), the two extant wild subspecies are both listed as critically endangered. African wild asses have been captured for domestication for centuries and this, together with interbreeding between wild and domestic animals, has caused a distinct decline in population numbers. There are now only a few hundred individuals left in the wild. These animals are also hunted for food and for traditional medicine in both Ethiopia and Somalia, where recent civil unrest has led to an increased number of weapons in circulation. Competition with domestic livestock for grazing, and restricted access to water supplies caused by agricultural developments, pose further threats to the survival of this species. The African wild ass is legally protected in the countries within which it's currently found, although these measures often prove difficult to enforce. More effective protection measures need to be adopted if the status of this species is to improve. A protected population of the Somali wild ass exists in the Yotvata Hai-Bar Nature Reserve in Israel, to the north of Eilat. This reserve was established in 1968 with the view to bolster populations of endangered desert species. Populations of horses and asses are fairly resilient, and if the species is properly protected it may well recover from its current low.
