Notes on the vegetation of Amazonia I. A preliminary note on the origin of the open white sand campinas of the lower Rio Negro

The origin of the open areas of white sand campinas of the lower Rio Negro is discussed. Campinas are compared with the denser campina forests or caatingas of the upper Rio Negro. It is concluded that the campinas are areas of white sand forest cleared by Indians. Evidences from pottery shards and r...

Evidences from pottery shards and radiocarbon dating of charcoal deposited in the soil demonstrate that the campinas were occupied by Indians of the Guarita subculture around 800 A.D.
