Chapman's zebra (Equus quagga chapmani), named after explorer James Chapman, is a subspecies of the plains zebra from southern Africa.
Chapman's zebra are native to savannas and similar habitats of north-east South Africa, north to Zimbabwe, west into Botswana, the Caprivi Strip in Namibia, and southern Angola. Like the other subspecies of plains zebra, it is a herbivore that exists largely on a diet of grasses, and undertakes a migration during the wet season to find fresh sources of food and to avoid lions, which are their primary predator. Chapman's zebras are distinguished from other subspecies by subtle variations in their stripes. When compared to other equids in the region Chapman's zebras are relatively abundant in number, however its population is now in decline largely because of human factors such as poaching and farming.
Studies and breeding programs have been undertaken with the hope of arresting this decline, with a focus on ensuring zebras bred in captivity are equipped for life in the wild, and that non-domesticated populations are able to freely migrate. A problem faced by some of these programs is that captive Chapman's zebra populations experience higher incidence of diagnosed diseases than non-domesticated populations due to the fact that they live longer, and so are less likely to die in the wild from predation or a lack of food or water.
Chapman's zebras are single-hoofed mammals that are a part of the odd-toed ungulate order. They differ from other zebras in that their stripes continue past their knees, and that they also have somewhat brown stripes in addition to the black and white stripes that are typically associated with zebras. The pastern is also not completely black on the lower half. Each zebra has its own unique stripe pattern that also includes shadow stripes. When foals are born, they have brown stripes, and in some cases, adults do not develop the black colouration on their hides and keep their brown stripes.
In the wild Chapman's zebra live on average to 25 years of age, however that can live to be up to 38 years of age in captivity. Males usually weigh 270–360 kg (600–800 lb) and stand at 120–130 cm (48–52 in) tall. Females weigh about 230–320 kg (500–700 lb) and stand as tall as the males. Foals weigh 25-50 kg (55-88 lb) at birth. Adult zebras can run at up to 56 kilometres per hour (35 miles per hour) and have strong eyesight and hearing which are essential evolutionary defence mechanisms.
Chapman's zebras have been observed to spend a large portion of their day feeding (approximately 50%), and primarily consume low-quality grasses found in savannas, grasslands, and shrublands, however they occasionally eat wild berries and other plants in order to increase protein intake. While they show a preference for short grasses, unlike some other grazing animals they also eat long grasses and so play an important role by consuming the upper portion of long grass that has grown in the wet season to then allow for other animals to feed. Young foals are reliant on their mothers for sustenance for approximately the first 12 months of their lives as their teeth are unable to properly breakdown the tough grasses that the adults eat until the enamel has sufficiently worn away.
