Jamanxim River Jamanxim River The Jamanxim River is a river of Pará state in north-central Brazil. Originating in the Serra do Cachimbo, it is a tributary of the Tapajós, into which it flows a few kilometers upstream from Itaituba. The river flows through the Tapajós-Xingu moist forests ecoregion. It flows through the Itaituba I National Forest, a sustainable use conservation area established in 1998. The river basin also contains part of the Rio Novo National Park, a conservation unit created in 2006. Its hydroelectric potential, along with that of the Tapajós, was assessed by Eletronorte (Centrais Elétricas do Norte do Brasil S.A.),
Xingu State Park on the basis of a referendum of the people of Santa Cruz do Xingu by technicians from the State Environmental Foundation (FEMA). The agricultural frontier was limited by the amount of protected land, some of which had to be released for expansion of food production. The consultative council was established on 28 September 2007. The objectives are to protect and conserve the various ecosystems and to prevent human actions that would jeopardise the future of the many indigenous groups found in the park. The conservation unit is supported by the Amazon Region Protected Areas Program. Xingu State Park Xingu State
