This book on the Chilchos Valley in the northeastern slopes of the Andes in Peru attempts to understand how human activities have changed the landscape in the montane forests during the last 500 years. Settlements and terracesfrom the Chachapoya and Inca cultures in the Ceja de Selva (the high jungle) witness of an ample use in pre-Hispanic times.
