Pakistan has 29 protected areas known as national parks. As of 2012, 22 of these are under supervision of respective provincial governments and remaining are in private care. Only some of these are under the conservation scope of IUCN. Protection and conservation of the environment of Pakistan was included in the concurrent constitution of 1973. As a result, Environment Protection Ordinance was enacted in 1983, which was mainly regulated by the Environment and Urban Affairs Division. Later, a new system of 'Modern Protected Areas' legislation began at the provincial level which assigned the protected areas with designations such as national parks, wildlife sanctuaries and game reserves.
