 The protected areas network of Madagascar is managed by the Madagascar National Parks Association (PNM-ANGAP).
 The network includes three types of protected areas: Strict Nature Reserves (IUCN category Ia), National Parks (IUCN category II) and Wildlife Reserves (IUCN category IV).
 At the 2003 IUCN World Parks Congress in Durban, the Malagasy President, Marc Ravalomanana, announced an initiative to more than triple the area under protection from approximately 4200791 acre to over 14826322 acre (from 3% to 10% of Madagascar's area).
 This "Durban Vision", as it has been dubbed, involved broadening the definition of protected areas in the country and legislation has been passed to allow the creation of four new categories of protected area: Natural Parks (IUCN category II), Natural Monuments (IUCN category III), Protected Landscapes (IUCN category V), and Natural Resource Reserves (IUCN category VI).
 As well as allowing these new objectives for protected areas management, the new legislation also provided for entities other than PNM-ANGAP to manage protected areas, such as government ministries, community associations, NGOs and other civil society organizations, and the private sector.
