South African cheetah The South African cheetah ("Acinonyx jubatus jubatus"), also known as the Namibian cheetah, is the most numerous and the nominate cheetah subspecies native to Southern Africa. Since 1986, it has been classified as Vulnerable by the IUCN. The South African cheetah live mainly in the lowland areas and deserts of the Kalahari, the savannahs of Okavango Delta and the grasslands of the Transvaal region in South Africa. In Namibia, cheetahs are mostly found in farmlands. The South African cheetah was first described by the German zoologist Johann Christian Daniel von Schreber under the trinomen "Felis jubatus jubatus" in the Dutch Cape Colony in 1775.
Plains zebra The plains zebra ("Equus quagga", formerly "Equus burchellii"), also known as the common zebra or Burchell's zebra, or locally as the "quagga" (not to be confused with the extinct subspecies), is the most common and geographically widespread species of zebra. It ranges from the south of Ethiopia through East Africa to as far south as Botswana and eastern South Africa. The plains zebra remains common in game reserves, but is threatened by human activities such as hunting for its meat and hide, as well as competition with livestock and encroachment by farming on much of its habitat.
