The Perfect Place to Spend a Day in The Woods
Tucked away in the Chehalam Mountains of the Willamette Valley, Magness Memorial Tree Farm and Heater Grove is the perfect place to explore and learn about our internationally recognized demonstration forest and outdoor education site.
Land for this educational project was donated to the non-profit World Forestry Center in 1977 by generous local residents Howard and Panzy Magness.
The Heater Grove was donated in 1997 by the Robert Heater Family as a mature growth cedar grove. The grove has historically been used as the final resting place for members of the family.We are honored to be caretaker of their memorial and neighbor to the family farm.
Located approximately four miles south of Old Town Sherwood and 10 minutes west of 1-5 Wilsonville exit 283, Magness Memorial Tree Farm is an internationally recognized demonstration forest and outdoor education site only 45 minutes from downtown Portland.
Originally developed as a demonstration site for woodland owners to showcase forest management and silviculture, we are open to the general public, dawn to dusk, year round; barring private events and other special closures. With 2.5 miles of hiking trails (some with self guiding interpretive signs), sheltered picnic areas, meadows, streams and forests it is the perfect place to spend the day in the woods!
Leashed dogs are welcome at the property.
We wouldn’t be who we are without you!
