Pre-Colombian builders and Amazonian forests

A study of Amazonian rainforests in western Brazil, which contains more than 450 monumental pre-Columbian earthworks called geoglyphs, finds that the current bamboo forest has dominated the landscape for more than 6,000 years, and that pre-Columbian societies disturbed small areas in managed, palm-rich forests to construct the geoglyphs, providing insights into the exploitation of forest products for millennia prior to modern deforestation. - Read at PNAS.org
