The U.S. Forest Service has decided to close 39 miles of off-road vehicle trails that brought off-road enthusiasts to the Cherokee County area, North Carolina. Numerous off-road trails had become severely eroded, having eroded down to bedrock. All of the eroded soil washed into waterways and interrupted the health of fisheries. The district reports that of 2100 sediment traps installed, roughly one third had failed. Trailbuilders should take note of this, improve their designs, and better select the soil separation and reinforcement materials for the specific use and environmental conditions.
