    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 Both unpublished data collected by the management agencies and data published in reports are included.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.

  • Dakota, Nakota, Lakota Life (Worksheets)
    Dakota, Nakota, Lakota Life South Dakota State Historical Society Education Kit Dakota, Nakota, Lakota Life (Worksheets) Background Information: About 8.3% of South Dakotans hold dual citizenship. Most of the 64,000 American Indians living in South Dakota are members of the Lakota, Nakota and Dakota Nation (also known as the 1 Great Sioux Nation) as well as Americans. Lakota histories are passed from generation to generation through storytelling. One story tells about the Lakota coming to the plains to live and becoming Oceti Sakowin, the Seven Council Fires. The story begins when the Lakota lived in a land by a large lake where they ate fish and were warm and happy. A man appeared, and told them to travel northward. The Lakota obeyed, and began the journey north. On their way they got cold, and the sun was too weak to cook their food. Two young men had a vision, and following its instructions, they gathered dry grasses and struck two flint stones together, creating a spark and making fire. There were seven groups of relatives traveling together. Each group took some of the fire, and used it to build their own fire, around which they would gather. 2 As a result, they became known as the Seven Council Fires, or Oceti Sakowin. During the mid-17th century, nearly all the Sioux people lived near Mille Lacs, Minnesota.3 Pressured by the Chippewas, they moved west out of northern Minnesota in clan groups by the early 18th century.4 The three tribes spoke the same general language, but each developed dialects or variations, which also became their known name.
