Environmental impacts associated with the degradation of off-highway vehicle (OHV) trails have become a serious concern in many regions. Where OHV trails indiscriminately cross alpine areas, wetlands, steep slopes, and other areas with sensitive soil conditions, trails can become rutted, mucky, and eroded. Such areas are referred to as degraded trail segments. Degraded trails develop when trail use exceeds the trail's natural carrying capacity. This document provides land managers and trail users with an introduction to OHV trail degradation and outlines a framework for management responses.
Property management of off-highway vehicle (OHV) trails is one of the most important tasks for trail managers today. Title 36 of the Code of Federal Regulation Part 212.1, the Forest Service defines an OHV as any motor vehicle designed for or capable of cross-country travel on or immediately over land, water, sand, snow, ice, or marsh, swamp, or other natural terrain. In this report, off-highway vehicles, OVH, include everything from dirt bikes to swamp buggies, off-road vehicles, off-highway motorcycles, all-terrain vehicles, utility-terrain vehicles, four-wheel drive vehicles, such as pickup trucks and sport utility vehicles, and tracked vehicles. This illustrated report takes into consideration trail guidelines, fundamentals, assessments, management objectives, and layouts to reinforce the management framework presented to help OHV managers develop sustainable trails and protect the environment of surrounding trails. This framework provides a step-by-step approach to OHV trail management, incorporating sustainable design and management concepts with traditional trail management expertise and modern technological tools. Forest service and land management personnel, including farmers and ranchers that may utilize and manage multiple off-highway vehicles may be interested in this report.

This Low-Volume Roads Engineering Best Management Practices Field Guide is intended to provide an overview of the key planning, location, design, construction, and maintenance aspects of roads that can cause adverse environmental impacts and to list key ways to prevent those impacts. Best Management Practices are general techniques or design practices that, when applied and adapted to fit site-specific conditions, will prevent or reduce pollution and maintain water quality. BMPs for roads have been developed by many agencies since roads often have a major adverse impact on water quality, and most of those impacts are preventable with good engineering and management practices. Roads that are not well planned or located, not properly designed or constructed, not well maintained, or not made with durable materials often have negative effects on water quality and the environment.
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
