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 Both unpublished data collected by the management agencies and data published in reports are included.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. -
"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

Chapter 5 Resource Preservation
CHAPTER 5 RESOURCE PRESERVATION INTRODUCTION The citizens of Roanoke County have a strong desire to preserve the quality of the county’s natural, scenic and historic resources. The county’s natural features - including mountains, forests, productive soil, streams, fresh air and wildlife - serve to distinguish the greater Roanoke Valley as a uniquely attractive urban center. Roanoke County citizens recognize that the beauty of the existing natural environment attracts not only businesses and residents to our community but also tourists and sports enthusiasts. County citizens believe that it is essential to maintain the high quality of Roanoke County’s environment while accommodating the pressures for future growth and development. OPEN SPACE During the past twenty-five years, Roanoke County has experienced steady growth. From a population of 53,800 in 1970 that reflects the results of several annexations, the population grew 54 percent to 83,100 in 1995. Future population projections indicate that by the year 2010 the County population will be approximately 87,400. This growth in population and the accompanying shift in demographics - such as an aging population - are changing the traditional rural landscape of the County. New residents require more housing, schools, shopping centers, office buildings, roads, water and sewer facilities and parks and recreational services. The rural landscape is gradually becoming urbanized as a result of this growth. What was once an orchard is now a residential subdivision or a shopping center. What was once a hardwood forest is now an office building or condominium. Between 1982 and 1992 the number of farms in Roanoke County decreased 11 percent from 306 to 272. -

The California’s Geomorphic Provinces rocks are mostly buried beneath soils and covered by vigorous redwood forests, which thrive in a climate famous for summer fog and powerful winter storms. The rocks only reveal themselves in steep stream banks, along road and trail cut banks, along the precipitous coastal cliffs and offshore in the form of towering rock monuments or sea stacks.

Few of California’s State parks display impressive monoliths adorned like a Patrick’s Point State Park displays a snapshot of geologic processes that have castle with towering spires and few permit rock climbing.
