SKID ROADS AND SKID TRAILS The primary difference between a skid road and a skid trail is the degree of preparation for use. Main skid roads should be flagged, cleared, and graded. Skid trails, which are used for transporting logs from stump to main skid road, are usually not graded and need only minimal clearing. In developing a skid road and trail system, pay special attention to proper drainage and soil stabilization. The following items should be considered: Source Unknown 1. Landings - Locate landings in relation to the main haul road. Then lay out the skid road and trail approaches on a low grade to the landings. 2. Grades - Keep grades as low as the topography will permit. Do not go straight up the slope; proceed across the slope as much as possible. Grades of 20% or more should be avoided. Where unavoidable, they should be kept to short distances and make use of waterbars. 3. Avoid Streams, Wetlands, Rocky Slopes, and Steep Grades. Skid trails and skid roads should be located at least 50 feet from stream channels and wetlands wherever possible. 4. Stream Crossings - Use temporary bridges or culverts and obtain all appropriate permits/authorizations. 5. Use Waterbars wherever it is not possible to avoid going straight up or down slopes. 6. NEVER SKID THROUGH OR ACROSS STREAM CHANNELS, WETLANDS, SPRINGS, OR SEEPS. 363-2134-008 / March 31, 2012 / Page 297
