Abstract

soil erosion control in managed forests is undertaken, and best achieved, for two main reasons. The first relates to soil protection for the sustainable productivity of the forest resource. The second relates to the protection of valuable water resources located in forested catchments. The potential impacts of increased soil erosion and the subsequent delivery of this material off-site, include a general reduction in water quality, adverse health effects on aquatic species, and an increase in the delivery of nutrients and sorbed chemicals to watercourses. This article discusses soil erosion control in managed forests from this twofold perspective. It uses a conceptual framework that emphasizes the link between on-site erosion and the subsequent delivery of this material off-site to the stream channel. The importance of adopting erosion control practices that encourage the reduction of surface runoff, and thereby off-site sediment delivery, is emphasized. The role and effectiveness of selected best management practices used in the control of soil loss and sediment delivery in forestry environments is also discussed within this framework.
