Turkey Hunt Underway on Dunn Forest through 5/31/2019

Updated on: 05/13/2019 - 13:19

The Spring Turkey Hunt is currently underway on the Dunn Forest through May 31st.  Out of the 97 people who applied, 50 were randomly selected and received a letter in the mail allowing them to access the Dunn Forest for walk-in hunting.  Hunters may use a shotgun or bow (ODFW approved weapons), and may only hunt turkeys.  

You may or may not see hunters while you are out on the Dunn Forest over the next month.  Here are some tips from the USDA Forest Service on hunting safety for hunters and other visitors.   

Here is a map of the area where hunting is allowed, for your reference.

Peavy Arboretum to be Closed Morning of Monday 5/20/2019 for Select Herbicide Application

Peavy Arboretum will be closed from 5:00am-12:00pm on Monday, 5/20/2019 for herbicide application in select areas.  All road ditches and shoulders within the Arboretum will be sprayed to address weeds and unwanted grasses.  Only two trails – Red Cedar Run and Fir Hollow Trails – will be sprayed to control vegetation growing in the trail bed.  Spot spraying of invasive weeds will occur throughout the Arboretum to address individual plants.   

Signs posted on-site will list the date and time of application, chemical name, and re-entry interval.  They will be left in place for one week.   

Closure Violations and Vandalism Lead to Unsafe Conditions

Over the past couple of weeks, several people have chosen to go through the clearly marked closures on the 600 (Patterson) Road while the logging crews were actively working.  People who enter this closure area travel directly through/around high visibility barriers and signs on barricades placed in the roadway. 

While you may not hear harvest activities from the closure location, this does NOT mean that harvest operations are not occurring.  For example, the saw could be turned off temporarily during cutting, or the closure could be located some distance from the harvest area. Logging crews often work on weekends, evenings, and early mornings!  

We have also been having lots of problems with people removing closure information, signs and markings, which has led other people unknowingly entering closure areas on several occasions.  We replace these materials as soon as we catch them, but please be aware that this could occur, and review the closures online before heading out on your visit. On-line materials are kept up-to-date.  

Logging has been identified as the job with the highest fatality rate in the US.  Logging crews have extensive communications and safety protocols in place to operate as safely as they can.  People passing through an active harvest site without the benefit of those protocols are putting themselves - AND the harvest crews - in extreme danger.  

Here are the hazards associated with harvest areas:

  • Trees falling, sometimes across roads and trails
  • Large machinery moving around and transporting logs
  • Compromised ability to communicate hazards due to loud noises and distance
  • Danger to harvest crews while trying to respond to unpredictable hazards associated with untrained people passing through the area 

This weekend, Benton County Sheriff's Department will be on-site to cite people going through the closures.  

We recognize that the vast majority of people receiving this e-mail are entirely respectful of the closures on the Forest.  THANK YOU!!!  We could really use your help in passing this message along within your communities to try to reach the very few folks who are violating these closures.

Why are closures 24/7, and why are they so big? Check out these Frequently Asked Questions  

Please let us know if you have questions or ideas, and thank you for your help

Spring Herbicide Spray Completed on McDonald and Dunn Forests

Update (4/17): Herbicide application has now been completed on the McDonald and Dunn Forests. Signs remain on-site at each spray area with the date of application written on them, and will remain in place for one week. Any remaining flagging strung across roads and trails will be removed tomorrow, 48 hours after application.

Crews will be working from the south of the McDonald Forest (near Oak Creek) to the north, finishing up their work in the Dunn Forest. Updates will be posted here if plans change.

All treatment units on McDonald and Dunn Forests will be sprayed using backpack sprayers. No helicopters will be used. The spray targets vegetation in the units, and will not be applied to road surfaces.

During application, staff will be positioned at roads and official trails leading into spray areas to keep people away. Signs posted on-site will indicate the re-entry times associated the chemicals used. The date of application, name of the chemicals used, and the industrial re-entry interval will be written on signs posted at entry points into each treatment area, and will remain in place for one week.

This herbicide application intended to control growth of non-native plant species and competing vegetation in recently reforested areas. This herbicide application will be conducted in compliance with State and Federal regulations and under a supervision of a licensed pesticide applicator.

Recreation Study Results from McDonald and Dunn Forests (2018)

Updated on: 05/09/2019 - 15:08

Acting on its mission to provide quality recreation and learning opportunities, the OSU Research Forests funded researchers Chad Kooistra and Ian Munanura in a research study to survey recreation users of the McDonald and Dunn Forests in 2017. These data, and the recommendations made by the authors, are incredibly valuable to Forest Managers in making decisions for the Forests’ Recreation and Engagement Program.

Seasonal Restrictions in Effect 10/31-4/15

Updated on: 03/13/2019 - 11:09

Seasonal closures go into effect for bikes on the Intensive Management and Calloway Creek Trails starting this month.  Extendo Trail will remain open on a trial basis this winter, thanks to the hard work of our volunteers in preparing it for winter use!  

Also a reminder that the use of any trail is not allowed when travel will result in leaving a track in the mud, or when there is significant standing water on the trail.  This is especially important for natural surface trails such as Dave's, Vineyard Mountain, and Beautiful Trails.  


New Lewisburg Saddle Parking Area Open for Business!

Updated on: 03/13/2019 - 13:24

We are pleased to announce the new parking area at Lewisburg Saddle is open and available for use. As this is a new parking area, please take a little extra time to notice the entry and exit points to be sure and use the site according the the designed traffic "flow." You'll see that traffic is one-way only, and that parking is head-in. Please keep in touch if you experience any issues in using the new parking area.

At this time, the additional pullout located to the north of the new parking area (at the end of Sidesaddle Trail) is designated for trailer parking only. Please keep this area open for our equestrian friends who are unable to park at the parking areas at the top of the Saddle - even one passenger vehicle parked in the wrong spot can make it impossible for a trailer to use this area.

As a heads-up about next steps at the Saddle, we will be working with Benton County Public Works to install more of the delineators along the shoulder between the "old" and "new" parking areas. We are also continuing the analysis of the rest of the shoulder parking, which may result in some additional shoulder closures. Please stay tuned and we'll share results with you when we have them!

Special thanks to Oregon Parks and Recreation Department for the Recreation Trails Program grant that made this project possible. Thanks also to our partners at Benton County Public Works and staff members Stephen Pilkerton, Matt McPharlin and Ryan Brown, as well as all of the student workers and CORE volunteers who did much of the heavy lifting. Thanks also to all of YOU for your patience during this long construction phase!
