The Selous Game Reserve in the United Republic of Tanzania is one of the largest protected areas in Africa that remains relatively undisturbed by humans. A unique feature of Selous is the vast variety of habitats found in the region, including grasslands, riverine forests, swamps and Miombo woodlands. Experts call it a "valuable laboratory for ongoing ecological and biological processes."
Perhaps even more interesting, though, is the massive range of wildlife found in Selous, including crucial predator/prey relationships. You'll see cheetahs, giraffes, elephants, black rhinoceros, hippopotamus and crocodile, in addition to many more species.
The Selous Game Reserve faces many severe threats, including the exploration and extraction of minerals, oil and gas.
