Numerous mammals are found in the Bushveld including lions, African leopards, South African cheetahs, southern white rhinos, blue wildebeest, kudus, impalas, hyenas, hippopotamuses and South African giraffes. A significant extent of the Bushveld exists in the north-east including Kruger National Park and the Sabi Sand Game Reserve, as well as in the far north in the Waterberg Biosphere. South Africa houses many endemic species, among them the critically endangered riverine rabbit (''Bunolagus monticullaris'') in the Karoo.
