User fees for federal Wilderness have been suggested as a way to reduce deficit spending on Wilderness recreation and supplement decreasing management budgets. This study examines the users of Linville Gorge Wilderness, a federal free area, and Grandfather Mountain Backcountry, a nearby private fee area, to determine if fees would exclude any socioeconomic or other user group who presently uses wilderness and determine if fees are acceptable to users. The study compares users' socioeconomic characteristics and travel cost demand functions and analyzes attitudes towards fees to determine the extent to which fees are likely to change use behavior. No difference is found in the socioeconomic characteristics of the users of the fee and the free area, suggesting fees excluding any for federal Wilderness are equitable, not excluding any socioeconomic group currently using Wilderness. The trip demand functions of the travel cost models for the two areas are statistically the same, suggesting users are making the same economic decision when visiting each area. Fees are found to be acceptable to users if Wilderness will deteriorate without fees and fee revenues are spent on Wilderness management. Users suggest about $25 for an annual Wilderness permit and about two dollars for a daily fee as reasonable amounts. Most users say the fee at Grandfather Mountain does not influence their decision to visit, suggesting fees will not greatly affect demand at federal Wilderness. The site demand function for Linville Gorge predicts a large decrease in demand, but this is common to most travel cost models and does not usually prove true. Further research of the travel cost model and the administrative feasibility of suggested fee levels is recommended. / M.S.
