Namibia has 26 parks and reserves that help to preserve and protect rare and endangered species. This has been very important for conservation since almost half of all species in Namibia are of some conservation concern. The Conservancies have helped to expand migration corridors and increase the perceived value of wildlife which has helped to mitigate human-wildlife conflict and increase economic development in ecotourism. Many wildlife populations are now on the rebound including black rhino, elephant, lion and cheetah.
