Describes several types of geosynthetics; explains basic geosynthetic design and utilization concepts for trail construction in wet areas; and provides geosynthetic product information.

Ln this manual we have described the common techniques for building a wetland trail. We have also included information on some of the more unusual materials and tools.

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.
