The African rhino is divided into two species, the black rhino and the white rhino. White rhinos mainly live in South Africa, but they have also been reintroduced to Botswana, Namibia, Swaziland, and Zimbabwe. Southern white rhinos have been introduced to Kenya, Zambia, and Cote d’Ivoire. The majority of the black rhino population—98%—is concentrated in four countries: South Africa, Namibia, Zimbabwe, and Kenya. South Africa houses 40% of the total black rhino population. There are some black rhinos in the region spread between Cameroon and Kenya.
