Revered by anthropologists as the 'cradle of humanity', Kenya is also the heart of African safari country, known for the great variety of its wildlife and is especially famous for its big game animals associated with the African savannah. The major big game species include elephants, rhinoceroses, zebras, giraffes, and lions and other large cats. Although many of these species are protected in national parks and game reserves, hunters have severely reduced the number of large mammals in Kenya, particularly elephants and rhinoceroses.
