A newly completed study, "Assessing and Understanding Trail Degradation: Results from Big South Fork National River and Recreation Area," by Dr. Jeffrey L. Marion of Virginia Tech University adds fresh information to help trail enthusiasts understand and manage trail impacts.
The complete study, published earlier this year, is available online. The research was conducted at Big South Fork National River and Recreation Area, located in Kentucky and Tennessee. Park officials commissioned the research to provide information and tools for their Road and Trails Management Plan.
Dr. Marion investigated a large sample (78 miles) of shared-use and single-use trails, measuring impacts across a variety of matrices. His research quantifies the trail impacts of different user groups and offers objective guidance on sustainable trail design, construction, maintenance and management. The study also provides state-of-the-art trail assessment and monitoring procedures.
In its summary discussion, the study states, "trail position, trail alignment, grade, water drainage, and type of use are all significantly influential variables" in trail sustainability (p36).
IMBA has long worked to develop and share trail management techniques that minimize resource impacts and provide high quality visitor experiences. IMBA Trailbuilding Schools, held weekly for bike clubs, land managers and volunteers, highlight the principals of sustainable trail management. IMBA also offers state-of-the-art trail design and construction services through its professional trail consulting program Trail Solutions.
The study cites more than 70 sources, providing an up-to-date catalog of recreation ecology references. It also includes Trail Solutions: IMBA's Guide to Building Sweet Singletrack in a listing of "the best available trail maintenance references" (p39).
Dr. Marion is an Adjunct Professor of Natural Resource Recreation at Virginia Tech University and a recognized expert on recreation ecology and visitor impacts. He has conducted numerous studies on National Park Service trails throughout the country and serves on the Educational Review Committee for Leave No Trace, Inc.
