Abstract
Filter strip standards currently applied to forest roads in the southern Appalachian Mountains may specify greater widths than are necessary with prevailing construction practices. Measurements of the distance that sediment traveled downslope below newly constructed roads were less than previously reported. Distances were notably less if natural obstructions existed on the forest floor, brush barriers constructed at the edge of the right-of-way, road fills grass-covered, and roads outsloped and drained by broad-based dips. Discussion of management considerations lead to proposed revised guidelines for minimum filter strip widths for the southern mountains.
