Long-Term Anasazi Land Use and Forest Reduction: A Case Study from Southwest Colorado

Species of wood used for fuel changed significantly through time at a large Anasazi village in southwestern Colorado occupied from about A.D. 750 to 900. Changes also occurred in other records of plant use from this site, in the fauna utilized, and in the proportional representation of hafted tools. These and corroborating data from nearby sites suggest that the Anasazi occupation of the Dolores River valley and vicinity resulted in significant local deforestation. Anasazi settlement and mobility practices were affected by climate, human impact on the environment, and regional population densities.
