Abstract: | Campsites were studied in subalpine forests in the Eagle Cap Wilderness in Oregon, and in the Mission Mountains Tribal Wilderness and the Rattlesnake Wilderness in Montana. Research objectives were to examine ecological changes on these sites and the extent to which these changes become more pronounced as use increases For most parameters measured, impact on campsites used for only a few nights per year exceeds threshold values beyond which further increases in use have little effect Loss of litter, tree root exposure, and site enlargement are the major types of alteration that are more pronounced on sites occupied more frequently than several nights per year In heavily used parts of backcountry areas, this suggests that ecological change can be minimized by limiting use to a small number of sites In the three areas studied, campsite occupancy rates would probably have to be no higher than a few nights per year before dispersal of use among a large number of sites would be an ecologically sound strategy |
