Abstract
  • These are the proceedings of the third short course in the management of young Douglas-fir and western hemlock con­ducted by the School of Forestry, Oregon State University, June 15-18, 1970. The course included one day of lectures and discussion on the campus of Oregon State University, two all-day field trips to observe management, and one day of a "sound-off" session in which all participated. The 53 registrants came from Oregon, Washington, and California. The opportunities in young-growth management are great. European foresters have managed Douglas-fir successfully longer than foresters in the Pacific Northwest and, even though both the economics and ecological conditions in Europe differ from ours, foresters in the Pacific Northwest will profit from knowing about their experiences. Administration and operation of partial cuttings are more complicated than final harvest cuttings and the economics of the management program have not been determined com­pletely. The knowledge and experience, then, of foresters active in research and management of young forests are especially relevant. But young-growth management not only must be finan­cially sound but also ecologically safe and esthetically accept­able. For instance. red alder, a valuable species economically, is also valuable biologically because it fixes nitrogen in the soil. And it may play an important role in the control of Poria weirii, a serious root rot of Douglas-fir. Skillful management can maintain or improve esthetic qualities of the forest. This short course was oriented toward those goals.
