Based on ethnohistoric research, Harold Hickerson argued that deer were more abundant in the buffer zone between the territories of two warring tribes (Sioux and Chippewa) in the Upper Midwest than in either tribe’s home territory. Hunters were wary of entering the buffer zone (but did not completely avoid them) because of the risk of running into their enemies. Once conflict between the two tribes ended, deer hunting resumed in the buffer zone, leading to a decrease in deer populations.

A more recent series of articles debated whether the buffer zone concept applied to Native Americans and animal populations in the western United States encountered by Lewis and Clark in the early 1800s. Click on the links for pdfs of these articles.
