Jeff is a Research Biologist at the Eastern Ecological Science Center at Blacksburg, VA.
Jeff Marion grew up exploring the woods, streams, and caves of Kentucky, developing strong interests in nature study and high adventure outdoor activities. One of four Eagle Scouts in his family, he served for five summers at Philmont Scout Ranch in New Mexico, teaching backpacking and climbing skills. Coursework in biology, ecology, and geology at Wittenberg University led to a B.S. in Biology (1979), and M.S. and Ph.D. degrees in Recreation Resources Management from the University of Minnesota (1982/84). Graduate studies focused on recreation ecology research, combining strong personal interests in the ecological sciences with his continuing passion for outdoor recreational pursuits, particularly backpacking, climbing, caving, and canoeing. His doctoral research measured camping-associated environmental impacts in the Boundary Waters Canoe Area Wilderness to investigate relationships between biophysical impacts, amount ofuse, and plant community, soil, and ecological classifications.
Following a year teaching park management at the University of Wisconsin, River Falls campus (1984-85), Dr. Marion was employed as a Research Biologist with the National Park Service, Mid-Atlantic Region, duty-stationed at Delaware Water Gap National Recreation Area. Initial studies focused on visitor impact and carrying capacity research for rivers within three of the Region’s parks. In 1989, his duty station moved to Blacksburg, Virginia, where he established a Cooperative Park Studies Unit in the College of Natural Resources, Virginia Tech. Initial research focused on studies of campsite impacts and monitoring protocols at Shenandoah, Great Smoky Mountains, and Big Bend National Parks. In 1994, he was moved to the National Biological Survey and in 1997, to the U.S. Geological Survey, though he remained at Virginia Tech as Unit Leader of a Patuxent Wildlife Research Center Field Station.
At Virginia Tech, he is an Adjunct Professor in the Forest Resources and Environmental Conservation Department, where he works with graduate students in conducting his program of recreation ecology research. Studies have expanded to include a current focus on formal and informal trails, visitor impacts to cliffs, and the efficacy of management actions designed to avoid or minimize visitor impacts. Most studies are funded by the National Park Service but studies have also been conducted on National Forests, Fish and Wildlife Refuges, and in Central and South American protected natural areas that serve as ecotourism destinations.
A founding member of the Board of Directors of Leave No Trace and Chair of the LNT Educational Review Committee for ten years, he helped develop Leave No Trace principles, practices, educational materials, and courses. He is the author of the national Leave No Trace program's offical book: "Leave No Trace in the Outdoors," endorsed by the federal land management agencies His active involvement with this work continues and was extended to

Sustainable Management of Campsites: Research on the Appalachian and Pacific Crest National Scenic Trails
Current and increasing visitation to protected natural areas has the potential to negatively impact natural resources and threaten the quality of visitors’ experiences. In backcountry and wilderness settings land managers have often allowed visitors to select and create their own campsites, which surveys reveal are often close to water, formal trails, and other campsites. This research is focused...Sustainably Designed Trails: Recent Recreation Ecology Findings on Design Factors Affecting Soil Loss
An estimated 146 million Americans participated in more than 10.9 billion outdoor recreation activities in 2017. Virtually all protected natural areas have recreational trails as an essential infrastructure component to accommodate these outdoor recreation activities and visitor access, supporting a diverse array of opportunities and experiences that include nature study, hiking, camping, mountain...Research and Management of Informal (Visitor-Created) Trails in Protected Areas
Protected area managers provide formal trail systems to accommodate recreational visitation on resistant “hardened” treads, while protecting off-trail vegetation, soils, and wildlife. When formal trail networks fail to provide visitors the access and experiences they require, visitors frequently venture “off-trail” to fish, hunt, explore, climb, or engage in other off-trail activities. Even...Assessing Recreational Impact to Cliff Habitats and Rare Plants
Protected natural areas, including parks, forests, wilderness, and wildlife refuges, have a dual mandate to protect natural resources and accommodate recreational visitation. Recreational activities that occur on trails (hiking, mountain biking, horseback riding) and on recreation sites (picnicking, camping) can benefit from the development of a sustainable infrastructure of facilities that... - Multimedia
