Most of these arguments on forestry-water resources management center around either natural and social/economic sciences. For instance, occurrence of overland flow and soil surface erosion in monoculture Japanese cypress (Hinoki, Chamecyparis obtusa) forests has been noted and is believed to be a serious problem (e.g., sediment transport). Many of the existing Japanese cypress plantations were established in the 1960’s during a period of rapid economic expansion with high demands for timber and pulpwood. Thereafter, as the Japanese forest industry declined due to international competition and purchase of cheap timber from developing nations in Asia, overstocked stands of Japanese cypress were abandoned. Dense understory vegetation failed to develop because of low light conditions under the dense monoculture canopies. Therefore, variable amounts of mineral soil are typically exposed. Under such soil surface conditions, splash erosion and soil surface sealing or crusting may occur, thus reducing the infiltration capacity of the soil. This symposium will promote dimensions of discussions of both science and management related to forested watersheds, particularly focusing on water resources and flood mitigation. Various aspects of runoff generation with respect to forest stand conditions, ground cover, and forest management will be presented and discussed. Forest management guidelines, policy making, and land management practices related to forestry and water rescores management will also be discussed in the symposium. Invited speakers Session 1: Runoff Generation and Sediment Transport Jim Buttle (Trent University, Ontario, Canada) Professor Buttle has a long history of research on hydrological response and water chemistry. He has many experiences in forest and watershed management in Canada and throughout the world.
