George Brown, Dean and Director Emeritus, OSU College of Forestry and Oregon Forest Research Laboratory; George Ice, Fellow, National Council for Air and Stream Improvement (NCASI). Paired watershed studies have long been used to accurately assess the impacts of forest management, especially timber-harvesting on runoff and erosion from forested watersheds. George Brown was one of the researchers on the original 1959-1973 Alsea Watershed Study and will offer invaluable historical context on the science of paired watershed research. George Ice is the Principal Investigator on the current "Alsea Revisited" Watershed Study and will offer national expertise on the science of forest practices and watershed effects.
