Wilderness Landscape & Natural Heritage
McDonald-Dunn Forest is a significant educational and research forest owned and managed by Oregon State University, located to the west of Corvallis, Oregon. Comprised of approximately 11,000 acres of primarily second-growth coniferous forest, it is home to Douglas-fir, western redcedar, and western hemlock species. The forest terrain features rolling hills, creeks, and small streams, providing diverse habitats for wildlife such as black-tailed deer, rough-skinned newts, various birds, and small mammals. Established in 1933 through the combination of two separate forest parcels named after major donors John S. McDonald and J.A. Dunn, the forest supports sustainable forestry practices, ecological research, and hands-on student learning. For outdoor enthusiasts, McDonald-Dunn Forest offers over 40 miles of multi-use trails suited for hiking, mountain biking, and trail running that wind through mature forest stands and along riparian zones, some with spectacular viewpoints over the Willamette Valley. The area is also popular for birdwatching and seasonal mushroom foraging. While the forest is not a developed public park, it welcomes visitors year-round for day-use activities but emphasizes conservation and education. Important landmarks include the Marys Peak Research Natural Area on its western boundary and various experimental forest plots. Its proximity to Corvallis makes it a favorite local destination for outdoor recreation and environmental study, providing a blend of natural beauty and practical forestry management.
