Grévy's zebra populations are estimated at less than 2,000 mature individuals, but they are stable. Mountain zebras number near 35,000 individuals and their population appears to be increasing. Plains zebra are estimated to number 150,000–250,000 with a decreasing population trend. Human intervention has fragmented zebra ranges and populations.
They are shorter than in the mountain zebra and narrower than in Grévy's zebra. As with all wild equids, the plains zebra has an erect mane along the neck and a tuft of hair at the end of the tail. [ 15 ] [ 16 ] [ 17 ] The body hair of a zebra is 9.4 ± 4 mm (0.37 ± 0.16 in), [ 17 ] shorter than in other African ungulates.

In the Cape mountain zebra, the ground colour is effectively white, but the ground colour in Hartmann's zebra is slightly buff. [ 7 ] Adult mountain zebras have a head-and-body length of 2.1 to 2.6 m (6 ft 11 in to 8 ft 6 in) and a tail of 40 to 55 cm (16 to 22 in) long.
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. [4] 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 ...
As with all zebra species, Grévy's zebra's pelage has a black and white striping pattern. The stripes are narrow and close-set, broader on the neck, and extending to the hooves. [17] The belly and the area around the base of the tail lack stripes and are just white in color, which is unique to the Grévy's zebra.
