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
