Current Research 2004 Oregon State University's Forest Research Laboratory is the forestry research arm of the State of Oregon. It was established by the Oregon legislature in 1941. The mission of the Oregon Forest Research Laboratory is to conduct well-coordinated, problem-solving research that enables management and use of Oregon's forests for multiple values and products that meet society's needs, with special attention to social and economic benefits. The Laboratory's research provides information to improve the forest-related decisions of those who use, own, operate, or are otherwise affected by management of the forests of the Northwest and the products and services these forests provide. The Laboratory's research results are used by many—private landowners, state and federal land-managing agencies, interests, and others. Thus, Laboratory research affects virtually all Oregonians because of the importance of forests to them and to their state's economic health. This directory is designed to help users of the Laboratory's research identify the scientists and their current research projects. It is organized by the Laboratory's five research program areas: Forest Regeneration; Forest Ecology, Culture, and Productivity; Protecting Forests and Watersheds; Evaluating Forest Uses and Practices; and Wood Processing and Products Performance. Several special or integrated research programs and facilities are also described at the end of the research listings. Following each scientist's name is a departmental code, and, in some cases, one or more program acronyms, to help you contact the scientist for information about his or her work or opportunities for cooperation.
College Forests The College of Forestry has access to two major forest properties dedicated to research and education. The College Forests comprise the McDonald-Dunn, Spaulding, Marchel, and Blodgett forest properties, totaling about 14,000 acres. Gifts to the College of Forestry, they are managed by the College for enhancement of education and research. The 16,000-acre H.J. Andrews Experimental Forest on the Willamette National Forest is administered by the USDA Forest Service, and research is jointly managed by OSU and the Pacific Northwest Research Station under a National Science Foundation-sponsored long-term agreement.
