OSU Research Forests

Covering about 11,250 acres in the hilly country north and west of Corvallis, McDonald-Dunn is the OSU College of
Forestry’s largest research, teaching, and demonstration forest, and is one of the principal assets of the
College. There are usually 40 to 80 active research projects under way on the Forest at any given time. More
than 40 university classes receive part of their instruction on the Forest each year. The Forest also receives at
least 175,000 visits from hikers, bicyclists, equestrians, public school students, and teachers each year. The
College accommodates these uses by devoting a portion of its College Forest budget to maintaining the
Forest’s recreational and educational features, including an extensive all weather road system. Timber
harvested from the Forest produces revenue to maintain and operate the Forest, including recreational use,
and to meet special College instructional and research needs.
