According to the scientists in this study, wildness is one of the central qualities of wilderness. To say that an area is wild in this sense, the scientists believed that it must have two qualities: (1) it must have the quality of naturalness, and (2) it must be free from the control of humans. In this study, the scientists wanted to find out whether their belief that wilderness is more natural and freer from human control than other lands is really true.
