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-Tocantins-Araguaia moist forests its valuable trees, and many native fauna and flora have become locally extinct. Large-scale mining near Marabá and elsewhere have directly affected the environment, and demand large quantities of wood to run the smelters. During the period from 2004 to 2011 the ecoregion experienced an annual rate of habitat loss of 0.94%. Global warming will force tropical species to migrate uphill to find areas with suitable temperature and rainfall. Low, flat, deforested ecoregions such as the Xingu-Tocantins-Araguaia moist forests are extremely vulnerable. Conservation units include the Tapirapé Biological Reserve and Tapirapé-Aquiri National Forest. Xingu-Tocantins-Araguaia moist forests The Xingu-Tocantins-Araguaia moist forests
