Literature describing the effectiveness of best management practices (BMPs) applicable to forest roads is reviewed and synthesized. Effectiveness is considered from the perspective of protecting water quality and water resources. Both paved and unpaved forest roads are considered, but BMPs that involve substantial engineering are not considered. Some of the BMPs included are commonly used on roads; others are used less often. The synthesis focuses on quantitative BMP effectiveness and descriptions of processes or characteristics that influenced the effectiveness. Qualitative results and observations not supported by data are excluded. Most of the effectiveness results describe sediment losses and sediment delivery, but there is also some coverage of chemicals used as BMPs, such as dust palliatives and soil conditioners. Chapters and subheadings are based on how or where protection is provided, or type of BMP. The final chapter provides information on research needs and potential direction of BMP implementation in the future. Although there remains a great need to quantify BMP effectiveness more rigorously across more physiographic, topographic, climate, and soil conditions, the data provided in this synthesis give road and watershed managers and landowners a starting place for evaluating and selecting BMPs.
