[citation needed] The Jaci Paraná Extractive Reserve is divided between the municipalities of Buritis (21.29%) Nova Mamoré (12.98%) and Porto Velho (65.73%) in the state of Rondônia.

[2] The reserve would be included in the proposed Western Amazon Ecological Corridor, connecting it to neighboring conservation units.

[3] The reserve has suffered from invasion by loggers and squatters, and large amounts of timber have been illegally harvested.

[3] The Jaci Paraná Extractive Reserve was created by state governor decree 7.335 of 17 January 1996 with an area of about 205,000 hectares (510,000 acres) as a territorial space for sustainable use and conservation of renewable natural resources.

The State Department of Environmental Development (SEDAM) was to work with the Rondônia Institute of Land and Colonization (ITERON) to implement and manage the reserve.

State law 633 changed the limits of the reserve to exclude the area occupied by the Serra dos Três Irmãos Ecological Station, Rio Madeira Environmental Protection Area and Rio Vermelho State Forest.

Defending the decree, Deputy Ribamar Araújo (PT) said that the only development model that worked for Rondônia was for forest to give way to agriculture and livestock.

The state prosecutor noted that the constitution of Brazil gave government and society the duty to protect an ecologically balanced environment.
