The river flows through the Tapajós-Xingu moist forests ecoregion. The river rises in the Nascentes da Serra do Cachimbo Biological Reserve, a strictly protected conservation unit established in 2005. It is one of the headwaters of the Xingu River. The upper part and the lower part of the Curuá River are divided by two waterfalls, only apart. The first waterfall is tall and the second is tall. As a consequence, the fauna

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
