The results of outdoor recreation consumer surplus studies for national parks, national forests, state parks and state forests in the United States from 1968 through 2003 are compared and analyzed across activity type, locational region, and park designation. The resulting data set includes 1,229 observations, spanning 36 years, 28 types of activities, and 106 locations. All consumer surplus data were converted to 2006 United States dollars per person per day for comparison purposes. It was discovered that activity and park type played a significant role in consumer surplus values. Activities such as mountain biking, windsurfing, and rock-climbing were among the highest valued activities while visiting environmental education centers was the lowest. When comparing park types, it was found that on average, activities at National Parks had higher values than national forests, state parks, or state forests. This meta-analysis is the most extensive literature review in the history of non-market consumer surplus values for outdoor recreation in the United States ever conducted and should prove beneficial to anyone seeking information on outdoor recreation studies as well as those wishing to conduct a benefit transfer analysis for their own land management area.
