Obliterate trailways by placing logs, branches, rocks & debris in the trailway. Place obliteration materials to a thickness and density sufficient to conceal the trailway below and so that raindrops cannot directly impact the soil surface. When there is an eroded channel, place logs of 6 inches minimum diameter longitudinally in the bottom of the eroded channel and in contact with the soil as practically attainable. Use materials from nearby, but do not cut live trees closer than 30 feet from the trailway.

Construct Native Log Waterbars or Rock Waterbars at intervals of approximately 50 feet on the abandoned trailway.

Check dams are not appropriate – water must be directed off the trailway.
