Abstract
Biophysical measurements were taken on 96 paired campsites and controls in the Boundary Waters Canoe Area Wilderness of northeastern Minnesota. Multiple regression analysis was used to identify and evaluate factors affecting changes in bulk density, organic horizon thickness, and exposed soil associated with campsite use. The best predictors of change in bulk density were campsite age, Mineral soil organic content, organic horizon thickness, and offsite bulk density. Offsite organic horizon thickness and level of use were the best predictors of change in campsite organic horizon thickness. Level of use and campsite age were the best predictors of amount of exposed soil. Bulk density and exposed soil continued to increase with campsite age, even though all sites included in the study were 5 yr in age. Other studies have not found this relationship. This information can be used to assist managers in selecting recreation site locations and appropriate site management techniques.
