Oregon State University (OSU) has acquired more than 3,000 acres in the Tualatin Mountains, securing the last large block of undeveloped forest within 10 miles of Portland and transforming it into a publicly owned research forest and recreation destination.
The new Tualatin Mountain Forest will advance climate-smart forestry, expand equitable access to nature, and support Oregon’s outdoor recreation economy, which generates billions in revenue annually. Historically used for timber production and home to more than 40 miles of mountain bike trails requiring paid access, the land will now offer free public trails, providing new hiking, biking, and educational opportunities for millions of nearby residents.
In partnership with the Trust for Public Land, OSU will use the forest to research resilient forestry practices, restore habitat, and improve water quality across 20 miles of creeks and headwaters that feed into the Multnomah Channel and the Willamette River. The project was funded by the U.S. Forest Service, Metro’s Parks and Nature Bond Measure, and additional partners, including The Conservation Alliance. It marks the first major research forest acquisition for OSU in more than 60 years, representing a major win for collaborative conservation, outdoor access, and the long-term health of Oregon’s forests and communities.
