[4] The Mamirauá Sustainable Development Reserve is divided between the municipalities of Uarini (18.68%), Tonantins (1.24%), Maraã (26.74%), Japurá (1.33%) and Fonte Boa (52.01%) in the state of Amazonas.

At present, it is included in one of the ecological corridors to be implemented by the PPG-7 Program for the Protection of Brazilian Tropical Forests.

[8] In 2003 the property was expanded by the addition of the Anavilhanas National Park, Amanã Sustainable Development Reserve and Mamirauá Sustainable Development Reserve to form the Central Amazon Conservation Complex, a larger World Heritage Site.

Mamirauá has a human population estimated in 6,306 individuals, including amazonian caboclo, Ticuna, Cambeba and Cocama Amerindian groups.

The reserve also harbours other arboreal mammals species such as the brown-throated sloth, the South American coati, the northern Amazon red squirrel and the collared anteater.
