-----------------------------------------------
Starting today, the McDonald-Dunn is CLOSED to the public for roadside herbicide application.
The OSU Research Forests are conducting roadside herbicide applications across the McDonald, Dunn, and Cameron Forests. This work includes treatment along all roads, roadside ditches, and cut-banks.
To ensure public safety, the forests are closed to the public June 22 through 26, 2026.
As work locations vary throughout the closure, we will reopen completed segments of the forest to the public as soon as it is safe to do so. Please keep an eye on these Forest Updates via email, or on our Forest Update webpage for re-opening updates: https://f.mtr.cool/aaeadrtrqt
