Hundreds of geoglyphs, geometrically formed man-made earth works, have only recently been found in southwestern Brazilian Amazonia and adjacent Bolivia. Geoglyphs occur in an area that partly overlaps with bamboo-dominated forests that are exceptional rain forests because they are dominated by a single species. The aim of the project is to find out if there is a causal relationship between bamboo forests and geoglyphs.
