Assessing and Understanding Trail Degradation: Results from Big South Fork National River and Recreational Area Assessing and Understanding Trail Degradation: Results from Big South Fork National River and Recreational Area
This report describes results from a comprehensive assessment of resource conditions on a large (24%) sample of the trail system within Big South Fork National River and Recreational Area (BSF). Components include research to develop state-of-knowledge trail impact assessment and monitoring methods, application of survey methods to BSF trails, analysis and summary of results, and...

Assessing recreation impacts to cliffs in Shenandoah National Park: Integrating visitor observation with trail and recreation site measurements Assessing recreation impacts to cliffs in Shenandoah National Park: Integrating visitor observation with trail and recreation site measurements
The rock outcrops and cliffs of Shenandoah National Park provide habitat for several rare and endangered plant and animal species, including the federally endangered Shenandoah Salamander (Plethodon shenandoah; Ludwig et al., 1993). The location of the well-known park tour road, Skyline Drive, along the ridgeline provides exceptional access to many outcrops and cliffs throughout the park...

Recreation monitoring at Acadia National Park Recreation monitoring at Acadia National Park
Acadia National Park is one of the most intensively used national parks in the United States. While its annual visitation (2.2 million visits in 2004) does not rise to the levels of some of the “crown jewel” western national parks (Yellowstone National Park, for example, accommodated 2.9 million visits in 2004), visits to Acadia are concentrated on its comparatively small size of less...

Research for the development of best management practices for minimizing horse trail impacts on the Hoosier National Forest Research for the development of best management practices for minimizing horse trail impacts on the Hoosier National Forest
This research investigates horse trail impacts to gain an improved understanding of the relationship between various levels of horse use, horse trail management alternatives, and subsequent horse trail degradation. A survey of existing horse trails on the Hoosier National Forest was used to collect data on use-related, environmental and management factors to model horse trail impacts...

Communicating Leave No Trace ethics and practices: Efficacy of two-day trainer courses Communicating Leave No Trace ethics and practices: Efficacy of two-day trainer courses
Heavy recreational visitation within protected natural areas has resulted in many ecological impacts. Many of these impacts may be avoided or minimized through adoption of low-impact hiking and camping practices. Although ?No Trace? messages have been promoted in public lands since the 1970s, few studies have documented the reception and effectiveness of these messages. The U.S. Leave No...

A comparison of campfire impacts and policies in seven protected areas A comparison of campfire impacts and policies in seven protected areas
Using resource-monitoring data from seven protected areas, the effectiveness of three campfire policies—campfire ban, designated campfires, and unregulated campfires—were assessed based on the number of fire sites and the amount of tree damage. Results indicate that unregulated campfire policies permitted substantial numbers of fire sites and tree damage in campsites, although fire bans...
