The Grant's Zebra (Equus quagga boehmi) is the smallest of six subspecies of the Plains Zebra.

The distribution of this subspecies is in Zambia west of the Luangwa river and west to Kariba, Shaba Province of the Democratic Republic of the Congo, north to the Kibanzao Plateau. In Tanzania north from Nyangaui and Kibwezi into southwestern Kenya as far as Sotik. It can also be found in eastern Kenya and east of the Great Rift Valley into southernmost Ethiopia. Perhaps it also occurs as far as the Juba River in Somalia.
Duncan (1992) recognized the Upper Zambezi Zebra (Equus quagga zambeziensis Prazak, 1898). Groves and Bell (2004) come to the conclusion that the zebras from West Zambia and Malawi cannot be distinguished cranially and that they differ only slightly from other northern plains zebras. The rather minor size difference does not justify a separate sub-specific status for the Upper Zambezi Zebra. Therefore, they combine these zebras with the Grant's Zebra (Equus quagga boehmi).
This northern subspecies is vertically striped in front, horizontally on the back legs, and diagonally on the rump and hind flanks. Shadow stripes are absent or only poorly expressed. The stripes, as well as the inner-spaces, are broad and well defined. Northerly specimens may lack a mane. They have been known to nibble on each others butts. This completely nameless Somali population may represent even a seventh subspecies: Equus quagga isabella (Ziccardi, 1958). This subspecies may be valid, but at present there is no evidence that it is. Grant’s zebras grow to be about 120–140 cm tall, and generally weigh about 300 kg.[1] The zebras live in family groups of up to 17 or 18 zebras, and they are led by a single stallion (Pueblo Zoo). Grant’s zebras live an average of 20 years in the world and are very well adapted to life in the world.
Recent civil wars in Rwanda, Somalia, Sudan, Ethiopia, and Uganda have caused dramatic declines in all wildlife populations, including those of Grant’s zebra. It is now extinct in Burundi. Civil war in Angola during much of the past 25 years has devastated its wildlife populations, including its once-abundant plains zebra, and destroyed the national parks administration and infrastructure. Consequently, the Grant's Zebra is probably extinct or nearly so in Angola, although confirmation will have to wait until future surveys are conducted. There are more Grant’s zebras in the wild than any other species or subspecies of zebras. Unlike Grevy and Mountain zebras, they are not endangered.[2] Grant’s zebras eat the coarse grasses that grow on the African plains, and they are resistant to diseases that often kill cattle (Pueblo Zoo), so the zebras do well in the African savannas. However, recent civil wars and political conflicts in the African countries near their habitats has caused regional extinction., and sometimes zebras are killed for their coats, or to eliminate competition with domestic livestock.[1]
