Geographic Range [top]

Range Description:	Plains Zebra range from southern Sudan and southern Ethiopia, east of the Nile River, to southern Angola and northern Namibia and northern South Africa (formerly ranging south of the Orange and Vaal Rivers to the Cape) (Hack et al. 2002; Klingel in press). They are now extinct in two countries in which they formerly occurred: Burundi and Lesotho. There is no information on their status in Angola, where they may also be extinct. The six morphologically defined subspecies are distributed as follows (following Groves and Bell 2004, and Klingel in press): E. q. crawshaii(Crawshay’s Zebra) occurs in Zambia, east of the Luangwa River, Malawi, south-eastern Tanzania from Lake Rukwa east to Mahungoi, and Mozambique as far south as the Gorongoza district; E. q. borensis ranges in north-west Kenya, from Guas ngishu and Lake Baringo, to the Karamoja district of Uganda and south-east Sudan, east of the Nile River to the northern limit of the species at 32°N; E. q. boehmi (Grant’s Zebra or Boehm's Zebra) is found in Zambia, west of the Luangwa River, west to Kariba, Shaba Province of DR Congo north to Kibanzao Plateau; Tanzania north from Nyangaui and Kibwezi into south-west Uganda, south-west Kenya as far as Sotik, and east Kenya, east of the Rift Valley, into southern Ethiopia and perhaps to the Juba River in Somalia. E. q. chapmani (Chapman's Zebra) ranges from north-east South Africa, from about 24°S, 31°E, north to Zimbabwe, west into Botswana at about 19°S, 24°E, the Caprivi Strip in Namibia, and southern Angola; E. q. burchellii (Burchell's Zebra) formerly occurred north of the Vaal/Orange Rivers, extending north-west via southern Botswana to Etosha National Park and the Kaokoveld, south-east to KwaZulu-Natal and Swaziland. It is now extinct in the middle of its range. E.b. antiquorum is now included in this subspecies; E. q. quagga (Quagga) occurred in the former Cape Province, south of the Orange and Vaal Rivers and west of the Drakensberg. Now extinct.

Population [top]

Population:	Plains Zebra are locally common throughout their range both in and also outside protected areas (especially in Kenya and Tanzania). Total numbers were estimated at ~660,000 in 2002 (Hack et al. 2002). Over 75% of the world’s Plains Zebra are of the Grant’s subspecies (E. q. boehmi), with some 200,000 in the greater Serengeti/Mara ecosystem; Serengeti National Park supports the world’s single largest Plains Zebra population (151,000) (East 1997; Hack et al. 2002). Current information on total population size is limited. Aerial survey data from Tanzania indicate that there may have been a population decline of approximately 20% from the late 1990s to the mid-2000’s (Hack et al. 2002; TAWIRI/TWCM pers comm. 2008). The True Quagga subspecies (E. q. quagga) has been extinct since the end of the 19th century (ca. 1883). Recorded densities of Plains Zebra include 0.9/km² in Kruger National Park (Smuts 1976) and 22/km² in Ngorongoro (ground count) (Klingel 1967).
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	Plains Zebra live in all habitats in Africa from sea level to 4,300 m on Mount Kenya, with the exception of rain forests, deserts, dune forests, and Cape Sclerophyllous vegetation (Duncan 1992; Klingel in press). Plains Zebra are selective grazers, and in the Serengeti Grogan’s (1973) research indicated that Pennisetum mezianum was a preferred species. He compared proportions ingested to their availability in the sward and found that there was significant selection and rejection of grass species. In several areas, their movements are directly correlated with the availability of water, moving to grazing areas during the rains and concentrating near permanent rivers or pools during the dry season. The Serengeti migratory subpopulation concentrates during the rains from November to May in the Serengeti plains. At the beginning of the dry season in June it migrates to the western and northern parts of the Serengeti National Park and adjacent areas, and into the Mara National Reserve in Kenya (Klingel in press).

Threats [top]

Major Threat(s):	No major threats appear to be resulting in range-wide population declines, but habitat loss and overhunting are resulting in localized declines in some areas. Although no country within this species’ range is free of either problem, loss of habitat appears to be more of a concern in the southern half of the range, while poaching appears to be more significant in the northern half. Nonetheless, the Plains Zebra is a relatively resilient species that has demonstrated a remarkable ability to recover from population declines when provided with suitable habitat and protection from overhunting (Hack et al. 2002). The Quagga was driven to extinction in the late 19th century by overhunting and competition with livestock.

Conservation Actions [top]

Conservation Actions:	Plains Zebra occur in numerous protected areas across their range, including the Serengeti National Park (Tanzania), Tsavo and Masaai Mara (Kenya), Hwange National Park (Zimbabwe), Etosha National Park (Namibia), and Kruger National Park (South Africa). Hack et al. (2002) proposed the following conservation actions for the species: 1) Improve coverage and frequency of monitoring; 2) Improve risk assessment; 3) Quantify and manage genetic diversity both globally and locally; 4) Increase the understanding of the species' basic biology'; and 5) Investigare the economics of alternative utilization stategies.
