Abstract
The Clearwater National Forest in Idaho accelerated its road removal (also referred to as road decommissioning or road obliteration) program following floods that impacted the Northwestern United States over the winter of 1995-96. In the wake of the floods, landslides originating on closed or abandoned roads were identified as a major cause of sediment delivery to streams. The primary objective of road obliteration on the Clearwater National Forest is to reduce watershed impacts by reclaiming roads no longer necessary for the Forest's transportation system. Roads are inventoried for stability needs. Redundant (i.e. those not needed for management) and unstable roads become obliteration candidates. Road obliteration is accomplished using heavy equipment to decompact road surfaces, remove drainage structures and fill material from streams and draws, and recontour through unstable areas. Various methods are used to control erosion from work sites and revegetate the obliterated template.
