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 16 national parks, with plans to expand existing parks. Conservation of eco-systems in all areas designated as national parks is the core business of the organisation.
Nature-based or wildlife tourism is the main source of income that is ploughed back for management, regulation, and fulfilment of all organisational mandates in the national parks.
The primary role of Tanzania’ national parks is conservation. The 16 national parks, many of which form the core of a much larger protected ecosystem, have been set aside to preserve the country’s rich natural heritage, and to provide secure breeding grounds where its fauna and flora can thrive, safe from the conflicting interests of a growing human population.
The existing park system protects a number of internationally recognised bastions of biodiversity and World Heritage sites, thereby redressing the balance for those areas of the country affected by deforestation, agriculture and urbanisation. The gazetting of Saadani and Kitulo National Parks in 2002 expanded this network to include coastal and montane habitats formerly accorded a lower level of protection.
Tanzania National Parks (TANAPA) is also currently acquiring further land to expand certain parks, and to raise the status of traditional migration corridors connecting protected areas.
By choosing to visit Tanzania you are supporting a developing country’s extraordinary investment in the future. In spite of population pressures, Tanzania has dedicated more than 46,348.9 square kilometres to national parks. Including other reserves, conservation areas and marine parks, Tanzania has accorded some form of formal protection to more than one-third of its territory – a far higher proportion than most of the world’s wealthier nations.
