The Rio Cautário State Extractive Reserve adjoins the reserve on the other side of the Cautári River.{{sfn|RESEX do Rio Cautário – ISA |loc=Informações gerais (mapa)}}

The reserve is in a region of crucial importance for conserving biodiversity and natural resources of the Amazon biome, and for supporting the traditional populations and indigenous communities.

It is in a strategic location in Rondônia, since the region has large areas used for livestock and for expansion of the agricultural frontier.{{sfn|Unidade de Conservação ... MMA}}

The Cautário River rises in the Uru-Eu-Wau-Wau Indigenous Territory and receives tributaries from the Serra Uopianes and the Serra Pacaás Novos.

It has clear waters fed by a region without major deforestation and silting of the river's margins.

It has rapids, but always with a drop of less than {{convert|2|m}}.

The most rugged stretch is between Redenção e Bom Destino.

It is navigable, even in the middle section around Bom Destino, but only in the rainy season.

It flows into the Guaporé/Mamoré river.{{sfn|Unidade de Conservação ... MMA}}

The brown-mantled tamarin (Saguinus fuscicollis) is widespread in the reserve.

The reserve holds a rich variety of bird species, but they have not been well studied.{{sfn|Unidade de Conservação ... MMA}}

Herpetofauna include a significant number of species that are known only in a few locations in Amazonia, and are therefore considered rare.

These include the lizards Enyalioides laticeps, Enyalius leechii, Leposoma osvaldoi and Tupinambis longilineus,

and the snakes Epictia diaplocia, Siagonodon septemstriatus, Drymobius rhombifer, Coluber mentovarius, Atractus insipidus, Erythrolamprus mimus, Ninia hudsoni, Oxyrhopus formosus, Oxyrhopus vanidicus, Siphlophis worontzowi, Micrurus mipartitus, Bothrocophias hyoprora and Bothrocophias microphthalmus.

Species that occur in Amazonia only in savanna enclaves include the lizards Hoplocercus spinosus, Micrablepharus maximiliani and species of Kentropyx and Ameiva, and the snakes Epicrates crassus, Chironius flavolineatus, Drymoluber brazili, Oxyrhopus rhombifer, Pseudoboa nigra, Xenodon merremii, Bothrops mattogrossensis and Crotalus durissus.{{sfn|Unidade de Conservação ...

The Rio Cautário Federal Extractive Reserve was created by federal decree on 7 August 2001.

It is administered by the Chico Mendes Institute for Biodiversity Conservation.{{sfn|Resex Rio Cautário – ICMBio}}

It is classed as IUCN protected area category VI (protected area with sustainable use of natural resources).

An extractive reserve is an area used by traditional extractive populations whose livelihood is based on extraction, subsistence agriculture and small-scale animal raising.

Its basic objectives are to protect the livelihoods and culture of these people and to ensure sustainable use of natural resources.{{sfn|Unidade de Conservação ... MMA}}

On 6 July 2005 the Instituto Nacional de Colonização e Reforma Agrária (INCRA: National Institute for Colonisation and Agrarian Reform) recognised the reserve as meeting the needs of 22 families of small rural producers, who would qualify for PRONAF support.

The deliberative council was created on 10 June 2009.

On 24 December 2010 ICMBio grant the right to use the reserve for 20 years to the Associação dos Seringueiros do Vale do Guaporécessão (Association of Rubber Tappers of the Guaporécessão Valley).

The management agreement was approved on 30 May 2014.{{sfn|RESEX do Rio Cautário – ISA |loc=Historico Juridico}}
