Abstract

This article addresses questions of Holocene land use and anthropogenic environmental change in the upper Rio Paz Valley, El Salvador, before and after the arrival of the Spanish in the sixteenth century. A lacustrine sediment sequence from Chalchuapa records the impacts of prehistoric agriculturalists on a mid-elevation tropical watershed during the past 3700 years. The sediment core from Laguna Cuzcachapa contains unequivocal evidence for human manipulation of the landscape : high levels of maize and agricultural weed pollen, charcoal, magnetic susceptibility, and sediment flux
