Reducing Erosion Around Forest Roads Erosion in and around the dirt roads that are typically built in forests is a serious problem in mountainous terrain. If a portion of the road washes away, expen- sive repairs may be required; even when repair is not needed, the sediment from erosion reaches streams and harms fish. Forest managers need low-cost treat- ments that will prevent such erosion, and scientists from the Intermountain and Northeastern Stations have been provid- ing them. The scientists have shown first that no amount of treatment is a substitute for good design and construction. A little extra spent during construction may mean big savings in maintenance. Once a road is built, three treatments are likely to reduce erosion considerably: grass seeding, application of mulch, and windrowing of cut vegetation on fill slopes. A stand of grass is highly effec- tive in preventing erosion over the long term. Mulch is useful for short periods while vegetation is becoming established. The same is true for the windrows on fill slopes. Once vegetation is established on fill slopes, erosion is likely to be in- consequential. In the meantime, wind-. rows of construction slash offer cheap and effective protection. Use of these stabilized fill slope, treatments was found to eliminate 99 percent of the erosion from bare fill slopes. 3.
