Kenya's unique landscape supports abundant and varied wildlife of scientific, intrinsic and economic value and has considerable land area of wildlife habitat. The country has committed a total of 8 percent of its land mass (approximately 48 000 km2 for wildlife conservation in a total). This comprises 23 national parks, 28 national reserves, 6 marine national reserves, 4 marine parks and 4 national sanctuaries. In addition to the national parks and reserves, there are many private and community sanctuaries hosting big populations of wildlife. The privately-owned conservation areas are located mainly in the wildlife dispersal and migratory corridors and thus directly support the country's wildlife conservation efforts.
