Forest roads have been identified as the major contributor to sediment production from forested lands, accountingfor perhaps as much as 90% of all sediment produced. In recent years, increased concern and societal pressure has focusedon the impacts of forest roads and the effectiveness of erosion control measures. In addition, the reintroduction of nativespecies for erosion control has become a priority on many forestlands. This study evaluates the effectiveness of a woodexcelsior erosion mat, native species vegetation, and exotic species vegetation treatments in erosion control from forest roadsideslopes in the Talladega National Forest in Alabama over a 4year period. In comparison to bare soil control plots,treatments significantly reduced sediment and runoff yield from the road sideslopes. Mean sediment yield from the nativespecies vegetation, exotic species vegetation, and erosion mat treatments were 1.1, 0.45, and 0.80 g m 2 mm 1 , respectively.The native species vegetation was as effective as the exotic species vegetation and erosion mat in reducing sediment yieldfrom the forest road sideslopes.
