No field trip will be held this year

Lunch will be provided from 12:00 – 1:00 Monday and Tuesday. In lieu of posters, students who have preliminary results are encouraged to submit abstracts for “flash talks” this year. These will be a great opportunity for practice speaking at a conference, even with limited results.

Talks will be shorter this year (20 minutes max with questions) and breaks will be prioritized. We want people to socialize and reestablish connections! As a reminder, please submit abstracts by August 15th to Corey Green.

Virginia Tech has mandated vaccines for all students and has strongly encouraged all faculty and staff to be vaccinated. For more information regarding Virginia Tech’s COVID policies and safety measures, please visit the Virginia Tech Ready site: We strongly encourage all attendees of SOMENS this year to take all safety measures to ensure we have a successful event.

In the event that COVID variants make an in-person gathering not possible, the meeting will be moved to an online environment. Registration fees will be reduced to $75.00. For those who have already registered, you will be refunded the difference.

2022 Western Region COFE Seminar

8:00 Introduction to WR.COFE & SeminarJohn Sessions, Chair, Western Regional COFE & OSU FERM Department

Company Perspectives on Forest Operations Challenges resulting from 2020 fires

8:15 Overview of Archie Creek Fire – Roseburg Forest Products

Panel Overview: Lone Rock is a timber management and logging company that manages approximately 150,000 acres of timberland in SW Oregon. During Oregon’s 2020 Labor Day fire storms Lone Rock lost 6,000 acres in the Archie Creek Fire (Douglas County) and 2000 acres in the South Obenchain Fire (Jackson County). Long before both fires were completely contained, Lone Rock began planning and implanting salvage harvest of the mature burned timber located within the fire scars.

Panel Discussion: The Lone Rock Timber/Logging Co. Salvage Harvesting Effort After the Archie Creek Fire

  1. Engineering/Survey – Methods and tools employed to re-establish pre-fire road construction layout and property lines obliterated by the fire.
  2. Timber Cutting – Differences between timber falling in the green vs. black; discussion on the importance of communication between cutting and logging crews.
  3. Road Construction – Emergency re-establishment and construction of road access; repairing heavily damaged road systems in the off-season.
  4. Logging – Post burn logging methods and safety difficulties encountered on exceptionally steep and difficult terrain.

9:45 Sponsor Update

9:55 Break (Refreshments Provided)

10:25 Sponsor Update

Overview of 2020 Fires on Weyerhaeuser Land

10:35 Panel Overview: In fall of 2020, Weyerhaeuser lost approximately 125,000 acres to 4 fires across Oregon. Weyerhaeuser’s targeted merch acres impacted by the fires was 45% of the overall burn acres. This was an extraordinary challenge for Weyerhaeuser to size up and reallocate resources to achieve their goals and was the largest salvage recovery effort since the Mount St. Helens eruption.

Panel discussion: Three topics of engineering, slope stability and harvesting will be covered by Weyerhaeuser supervisors and methods used to overcome these challenges during the Oregon salvage effort.

  1. Engineering: Processes and tools to permit, layout and meet state regulations on a tight timeframe with limited engineering capacity.
  2. Geology: High burn severity required increased focus of slope stability for both downstream public risk but also for worker protection.
  3. Logging: Post burn cutting and logging required increased capacity and expanded mechanization, including unique helicopter grapple logging opportunity to accomplish goal
