The Tanganyika National Parks Ordinance CAP  of 1959 established the organization now known as Tanzania National Parks (TANAPA), and Serengeti became the first National Park. Conservation in Tanzania is governed by the Wildlife Conservation Act of 1974, which allows the Government to establish protected areas and outlines how these are to be organized and managed.
National Parks represent the highest level of resource protection that can be provided. By February 2008, Tanapa had grown to 15 national parks, with plans to add 1 more in the near future, as well as to expand existing parks. Conservation of eco-systems in all areas designated as national parks is the core business of the organisation.
