The Rio Madeira Sustainable Development Reserve is divided between the municipalities of Manicoré (15.22%), Borba (46.1%) and Novo Aripuanã (38.68%) in the state of Amazonas.

[2] The vegetation of the Madeira-Purus interfluvial, in which the reserve is located, is of great importance for conserving biodiversity, with endemic species that are potentially vulnerable to anthropogenic threats, particularly birds.

[2] The Rio Madeira Sustainable Development Reserve was created by Amazonas state decree 26.009 of 3 July 2006 with the objectives of preserving nature, ensuring continuation and improvement of methods of extracting natural resources and quality of life of the traditional populations, and preserving and enhancing knowledge and techniques for managing the environment developed by the traditional population and others.

[4] On 12 November 2007 the Instituto Nacional de Colonização e Reforma Agrária (INCRA – National Institute for Colonisation and Agrarian Reform) recognised the reserve as meeting the needs of 388 small families, who would qualify for PRONAF support.

[4] The Bolsa Floresta program was extended to the residents in 2010, providing some income to families and community associations and other support in exchange for environmental stewardship.
