  • Wilderness Visitors and Recreation Impacts: Baseline Data Available for Twentieth Century Conditions
    United States Department of Agriculture Wilderness Visitors and Forest Service Recreation Impacts: Baseline Rocky Mountain Research Station Data Available for Twentieth General Technical Report RMRS-GTR-117 Century Conditions September 2003 David N. Cole Vita Wright Abstract __________________________________________ Cole, David N.; Wright, Vita. 2003. Wilderness visitors and recreation impacts: baseline data available for twentieth century conditions. Gen. Tech. Rep. RMRS-GTR-117. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 52 p. This report provides an assessment and compilation of recreation-related monitoring data sources across the National Wilderness Preservation System (NWPS). Telephone interviews with managers of all units of the NWPS and a literature search were conducted to locate studies that provide campsite impact data, trail impact data, and information about visitor characteristics. Of the 628 wildernesses that comprised the NWPS in January 2000, 51 percent had baseline campsite data, 9 percent had trail condition data and 24 percent had data on visitor characteristics. Wildernesses managed by the Forest Service and National Park Service were much more likely to have data than wildernesses managed by the Bureau of Land Management and Fish and Wildlife Service. Both unpublished data collected by the management agencies and data published in reports are included. Extensive appendices provide detailed information about available data for every study that we located. These have been organized by wilderness so that it is easy to locate all the information available for each wilderness in the NWPS. Keywords: campsite condition, monitoring, National Wilderness Preservation System, trail condition, visitor characteristics The Authors _______________________________________ David N.

  • Archeological Assessment of the Buffalo National River
    ARCHE0L0G1CAL ASSESSMENT of the BUFFALO NATIONAL RIVER by Daniel Wolfman Arkansas Archeological Survey Research Report No. 18 ARCHEOLOGICAL ASSESSMENT OF THE BUFFALO NATIONAL RIVER by Daniel WoIfman Arkansas Archeological Survey Research Report No. 18 MAY 1979 Report submitted to the National Park Service, Southwest Region by the Arkansas Archeological Survey under Contract No. CX 700030218 July, 1974 ABSTRACT The establishment of the Buffalo National River along one of the few remaining large, free-flowing streams in the state of Arkansas necessitates a comprehensive study of the archeology of the park area. This study, funded by the National Park Service, is the first step in the long process of preserving the park's archeological heritage, a significant portion of which is being lost due to surface collecting and digging by "treasure hunters" at the archeological sites. This report includes a review of published references relevant to the archeology of the Buffalo National River and a summary of reports prepared by amateur and professional archeologists on the 254 known sites within the boundaries of the Buffalo National River on file with the Arkansas Archeological Survey. Past archeological research is synthesized and recommendations are made including some ideas about how future archeological investigations may be approached to provide meaningful interpretations. i TABLE OF CONTENTS Preface and Acknowledgements 1 PART I.
