The races in south-central southern Africa are designated as plains zebra (E. quagga) and the rest through central and East Africa remain as Burchell’s zebra (E. burchelli). Most of the animals in the south have black stripes on a white background with “shadow stripes” on the white, with minimal striping on the lower legs and more white on the belly. Central and eastern populations usually lack the “shadow stripes”, have more extensive striping on the lower legs and on the belly. Ears shorter than in the other zebra species. populations in South Africa, Botswana, Namibia and Zambia. Huntable in all except Kenya. Distribution Race found in much of East Africa is Grant’s zebra, with Crawshay’s zebra in southern Tanzania and northern Mozambique. Chapman’s zebra is present in Mozambique and much of Zimbabwe, whereas populations in southern Angola and western Zambia are assigned to the so-called Upper Zambezi zebra. The Damara and Chapman’s races are restricted to southern Africa. Conservation standing By far the largest populations are in Tanzania and Kenya, with the greatest concentration being in the Serengeti/ Mara ecosystem, with other substantial Right front, 77 mm Right back, 83 mm Habitats Occur mainly in open grassed woodland and grassland savanna, avoiding any form of dense woodland. Behaviour They live in small family herds of an adult stallion, 2 – 5 mares and their young of one or two seasons. Much larger herds are commonly seen, especially during seasonal migrations, but the family units retain their integrity. Stallions vigorously defend or try to take over family herds, but stallions without breeding units join bachelor groups, or run alone. Some populations, as in the Serengeti/Mara system, are seasonal migrants, whereas others are largely sedentary. Those populations that do migrate are largely influenced by environmental conditions. Their barking “kwa-ha-ha” call is one of the distinctive calls of the African savanna. Food Predominantly grazers, but will browse during dry conditions. Shot placement Rifles and Ammunition Suggested Calibre: Flat-shooting cartridge from 7mm to .338. Bullet: Expanding bullet designed for penetration. Sights: Medium-range variable power scope. Hunting Conditions: Expect shots from 50 to 250 yards (46-230m). 9 Photo: G.&M. von Hasseln Plains Zebra Northern populations of plains zebra, here Grant’s from northern Tanzania, lack shadow stripes 8 Game Animals of the World
