[1] The reserve adjoins the Serra da Cutia National Park along its northwest border.

[2] 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.

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.

Its basic objectives are to protect the livelihoods and culture of these people and to ensure sustainable use of natural resources.
