The Jaci Paraná Extractive Reserve is an Extractive reserve in the state of Rondônia, Brazil. The traditional population is engaged in sustainable use of natural forest resources. It has been subject to illegal invasions by loggers and farmers. In 2014 an attempt was made to revoke the reserve.
The reserve is in an area of rubber concessions, generically called the Jaci Paraná concessions, that had been used for more than a century. It is federally owned land. The traditional residents mainly collect native fruits sich as cupuaçu, tucumã, açaí and bacuri, collect Brazil nuts and extract rubber. Most of the people practice hunting and fishing to some extent, and some agriculture. The Jaci-Paraná Rubber Tappers Association represents the residents in managing the reserve. The reserve has suffered from invasion by loggers and squatters, and large amounts of timber have been illegally harvested. According to Imazon between 2002 and 2007 the rate of deforestation in the reserve was 3.74%, second only to the Bom Futuro National Forest at 4.34%. By July 2007, or 20% of the total area, had been deforested.
By 2014 there were about 200 illegal cattle ranches in the reserve, with over 44,000 cattle. On 16 January 2014 owners of cattle in the reserve were given 40 days notice to remove their cattle. In response, state legislative decree 506 of 11 February 2014 revoked decree 7.335 that had created the reserve. The decree to revoke the reserve, and decrees that also revoked the Rio Madeira Environmental Protection Area, Rio Madeira B State Forest and Rio Vermelho State Forest, were opposed by the traditional populations but supported by loggers, ranchers and farmers. Defending the decree, Deputy Ribamar Araújo said that the only development model that worked for Rondônia was for forest to give way to agriculture and livestock. The decree was supported by 15 of the 16 deputies who attended the session. The Amazon Working Group, with more than 600 organizations representing farmers, rubber tappers, Indians, maroons, environmental organizations and human rights groups, published an open letter denouncing the state legislative decree. An injunction of 14 April 2014 by the state prosecutor suspended the decree. The state prosecutor noted that the constitution of Brazil gave government and society the duty to protect an ecologically balanced environment. It seemed that the area was being rapidly degraded, which justified fast and efficient measures. The case was tried by the court of Rondônia, which upheld the decision of the state prosecutor on 2 May 2016. The judgement also upheld revocation of decrees that had revoked the Rio Madeira Environmental Protection Area and the Rio Madeira B and Rio Vermelho state forests.
