Current Activities

Information about forest closures is located at key access points, and closures are clearly marked on-site. Harvest areas are extremely dangerous for visitors and harvest crews, with hazards from falling trees and large equipment. Thank you for your respect of these safety closures!

Updated 9/17/2018  Harvest Closure Lifted on Dunn 200 Road System Near Scout Trail

Harvest operations have been completed on the "Cuttlefish" Harvest on the 200 Road System near Scout Trail.  Visitors are free to use this area.  Please keep in mind that equipment will be piling slash within the unit for the next several weeks, and that road work associated with the harvest remains to be completed.  Thank you for your patience!

Posted 9/17/2018  Paving Occurring TODAY at Lewisburg Saddle - Expect Possible Closures

Benton County Public Works will be paving a thin strip between Sulphur Springs Road and the "new" parking area at Lewisburg Saddle today.  The paving will serve as a base for the installation of knock-down bollards which will separate vehicles on the road from the parking area.  One lane of travel on Sulphur Springs Road will be closed during this time, and the "old" parking area may be closed if needed for staging equipment.  This activity is expected to last one day if all goes according to plan.

Updated 9/5/2018  Fire Season STILL in Effect Despite Cooler Weather

As the days start to cool off, we wanted to remind folks that fire danger is still HIGH on the McDonald and Dunn Forests.  Despite cooler temperatures and a breeze, the forest remains bone dry as we await the fall rains. 

Here is a list of year-round fire prohibitions that apply to all roads, trails, parking areas and lands managed by the OSU Research Forests.  

  • No smoking or vaping (even in parking areas or parked cars)
  • No campfires or party fires
  • No fireworks
  • No use of spark producing devices such as chainsaws, mowers, weed eaters or vehicles (except administrative use)

If you see a fire while out on the forest, CALL 911 (with the location and road number)!  We rely on our wonderful visitors to serve as eyes and ears to help us identify and address problems immediately.  

We are currently at Industrial Fire Precaution Level II, which regulates how operations are conducted on forest lands protected by the Oregon Department of Forestry.  OSU Research Forests staff, researchers, and volunteers follow these regulations carefully to protect forest resources and neighboring properties.

Posted 8/31/2018 400 Gate Parking Closed Starting Tuesday, 9/4/2018

Beginning Tuesday, 9/4/2018 visitor parking will be closed at the 400 gate off Tampico Rd. on the Dunn Forest. This parking restriction is due to expected logging truck and lowboy traffic coming through the 400 gate in preparation for the Pacific Logging Congress' 8th Live In-Woods Show taking place September 13-15th. Anticipate additional upcoming parking closures at the 300 gate, and recreation restrictions on the 300, 340, 400, and 420 roads. Closures are expected to last through 9/21/2018 to accommodate traffic during and after the event.

Updated 8/29/2018 Herbicide Applications Complete Until Spring

UPDATE: The last of the summer herbicide sprays were completed the afternoon of Tues. 8/21/2018 on the McDonald and Dunn Forests.  The chemical has dried and public closures have been lifted.  Signs are being lifted and visitors are now welcome to access areas previously closed for herbicide treatment.  

Background: This herbicide application is intended to control the growth of non-native plant species and competing vegetation in reforestation areas.  This herbicide application was conducted in compliance with State and Federal regulations and under the supervision of a licensed pesticide applicator.   

If you have any questions regarding specific chemicals, please contact the National Pesticide Information Center 1-800-858-7378 npic@ace.orst.edu

Updated 8/17/2018  Harvest Operations Complete on the McDonald Forest; Visitors Welcome to Use Roads and Trails  

Harvest operations have been concluded on all units within the McDonald Forest, though some closures remain in effect on the Dunn Forest.  Please keep in mind that road workstill remains to be completed at a later date. 

You'll see that some of the forest looks a little different than last time you visited, as these forest stands have received either a thinning or clearcut prescription.  For a reminder of why clearcuts are sometimes used as a management tool on the OSU Research Forests, check out this newsletter article, pages 14-16

Posted 6/7/2018  Recreation Access Prohibited on Private Property to the Northwest of McDonald Forest

We wanted to let everyone know that the property owner sharing a portion of the northwest McDonald Forest boundary has decided to prohibit recreation use on their property, due to resource impacts from unauthorized trails.  You will see signs on-site, and closures will be enforced with support from the Benton County Sheriff’s Office.  The property is located north of the 760 and 720 Road systems, and is managed by Mason, Bruce and Girard.   Please contact Mason, Bruce, and Girard at 503-224-3445 with questions. 

Road Work

Intermittent road maintenence activities occur on the OSU Research Forests.  Please yield to the trucks.  Use extreme caution when approaching operating equipment and only pass when given the OK.
