Abstract: Multiproxy analysis of the 225-cm long sediment core Los Indios from the Yaque river valley in northwestern Dominican Republic (Hispaniola) shows environmental changes during the last 1150 cal yr BP. The observed changes show a period of little human distubance, followed by increasing human activity and a rapid intensification of these changes after Columbus’ arrival in AD 1492. The fastest changes on the landscape can be observed at 307 cal yr BP, when agricultural development in the Dominican Republic intensified.
