Amid ongoing and expanding interest in redwoods among landowners in western Oregon, OSU Forestry & Natural Resources (FNR) Extension convened Growing Redwoods in Oregon Science Meeting in October 2021.  Over 70 participants met virtually over two half-days, to discuss the potential of redwoods in Oregon.  Participants included researchers, public land managers, private landowners, geneticists, nursery specialists and other practitioners from Oregon and beyond.

Jim Johnson, familiar long-time leader of the Forestry & Natural Resources (FNR) Extension Program retired last winter.  Jim served 15 years with OSU, primarily as Associate Dean and Forestry Extension Program Leader but also led international programs and was interim Department Head for two departments in the College.  Jim did a lot to strengthen the FNR program in his time with us.  We wish him well in Virginia where he has moved to be close to a small flock of grandchildren.

Dr. Holly Ober has followed Jim as FNR Extension Program Leader.  She started here at OSU on June 1, taking the position of Associate Dean for Science Outreach and Program Leader for Forestry and Natural Resources Extension in the College of Forestry. 

Dr. Ober previously served as Associate Program Leader for the Natural Resources Extension Program in Florida.  She was also a Professor and Extension Specialist.  Her research there looked at the mechanisms that influence wildlife habitat selection and wildlife productivity in forests to better inform management strategies to balance multiple uses.  She is a recognized expert in bat ecology.  As an Extension Specialist, she taught landowners and land managers about sustainable management practices to provide habitat for wildlife while also meeting their other objectives.  A familiar topic here in Oregon. 

Holly is actually returning to Oregon, having received her PhD from OSU in Forest Science and Wildlife Biology in 2007.  Please welcome her when you get a chance.

The Oregon Master Woodland Manager (MWM) Program is one of the first and strongest forestry “peer to peer” learning and volunteer programs in the country. The MWM program had its start right here in Linn and Benton Counties in the early 1980s.

Don Carr, Mike Barsotti and Rick Fletcher were three new, young Foresters working for different agencies (The Natural Resources Conservation Service, the Oregon Department of Forestry and OSU Extension, respectively).  They were meeting regularly to find ways to cooperate and better serve landowners in the area.  Even working together, they recognized their limited capacity and reach as public foresters.  Seeing the effectiveness of the Master Gardener program, they imagined a similar “neighbor to neighbor” program with landowners helping other landowners find information and motivation.  This remains the heart of the MWM program to this day.

They launched a pilot training in 1984, with 10 participants.  The power of the program was immediately clear, and they went on to develop the statewide program which today has trained over 500 men and women all across Oregon.

The Master Woodland Manager Program is an OSU Extension learning and volunteer training program with roots in the mid-Willamette Valley.  Master Woodland Managers (MWMs) are experienced woodland owners who take an advanced training to improve their own skills and knowledge of woodland management.  In return for the training, each MWM commits to volunteer service to their community.  Their service covers a wide range of activities, including  landowner education,  supporting Extension program activities and Community Science projects. 

Over 35 years old and going strong, the MWM program has trained over 500 volunteers across the state.  MWMs collectively contribute thousands of hours of volunteer service each year (5,276 hours reported in 2019, before COVID).

The mid-Valley has one of the stronger MWM programs in the state.  The several dozen Linn,  Benton and Polk County Master Woodland Managers (MWMs) have been a great asset to the local woodland community over the years.  Their many contributions include hosting tours and demonstrations on their properties, making site visits to new landowners, writing news articles, supporting classes and other Extension educational programs, and providing core leadership for landowner organizations such as local chapters of the Oregon Small Woodlands Association. MWM also contribute to other natural resource organizations such as watershed councils and SWCDs as part of their volunteer service.

“Our favorite MWM volunteer activity has been one-on-one (visits) with other forest landowners. Our knowledge from the MWM training has helped us help our family, neighbors, friends and strangers with questions they have about their forests. If we don’t have an answer, we know others who can answer” say Hal & Elin, MWMs in Yamhill County.

Master Woodland Manager, like so many other Extension programs was significantly affected by COVID.  We cancelled or delayed several scheduled trainings around the state.  While many volunteers have remained active in leadership service, it halted many valuable and enjoyable services such as leading tours and making site visits.  We hope that changes soon.

Spring 2022 MWM training scheduled!

After complications and delays, we have now scheduled an MWM training for this area in Spring 2022.  It will be shared by Extension agents Brad Withrow-Robinson and Glenn Ahrens, so it will serve their combined 5 county area of the Willamette Valley.  We are unlikely to have another training in this area for another 5 years or more.

The training will be eight Saturday sessions from April 2 to June 25, 2022. The field-oriented sessions will rotate around several counties, from Clackamas to Benton. 

If you are an experienced landowner, and the MWM program sounds like something you would like to be part of, please contact me and ask for more information about the schedule, expectations and prerequisites, and application process. Brad.w-r@oregonstate.edu

Are you ready for the wildfire season? Some great new sources of information, including a  webinar series and resource packet, are available online to share with family, friends and neighbors as we work to be more aware and more prepared for fire.

Last summer’s 2020 wildfire events affected most Oregonians and we learned that EVERYONE living in Oregon should be prepared for a wildfire emergency. And here we are in July, with 2021 becoming another historic fire year.  So it is important to keep focused even though every community is different, and it can be difficult to navigate all of the resources.

Oregon State University’s Forestry & Natural Resources Extension along with state and local agencies and community partners, is helping Oregonians prepare for the reality of wildfire through greater awareness and action. OSU Extension’s new Fire Program hit the ground running, providing post fire programming last fall, and also a series of fire preparedness webinars this spring.

The Fire Aware. Fire Prepared webinar series aired in spring 2021. Topics included:

Are you seeing foliage scorch or other damage (as described in earlier post) and want to help increase our understanding of the impacts of our recent heat wave?  If so, you can report those effects to help foresters and researchers studying the longer-term impacts of this event. 

A group of scientists and forest managers at OSU and the USFS is asking people who observed these effects to report their observations by responding to this survey (link is also below). You will be using a website created by the Oregon Department of Forestry to survey drought impacts on forests.

Since this webpage was originally set up to report drought impacts on trees, you need to clarify that you are reporting about the recent heat wave. 

You will be asked to upload a photo of the injury.  Below that you are asked to provide a description or caption for the image.  In that description please note there  that you are reporting ‘impacts of the June 2021 heat wave and also include the phrase foliage scorch so they can retrieve these observations later for mapping and analysis of this extreme event. For example:

Impacts of June 2021 heat wave. Foliage scorch. Douglas-fir at day use area, Cascadia OR.
Impacts of June 2021 heat wave. Foliage scorch. Western redcedar at day use area, Cascadia OR.

People driving in and out of the valley have been alarmed by the damage to trees caused by the recent heat wave and wondering what it means.  They are not alone.

I have been asking around to try to get a clearer sense of the severity and extent of the effects of the heat wave around western Oregon.  What I have heard from within forestry and Extension circles is that the effects seem wide spread, but variable around the Coast Range and Cascades.  Hotspots I’ve heard about include areas along Hwy 20 near Toledo, and also above Sweet Home.  Hwy 58 around Lowell and Oak Ridge looks rough.  Damage seems less evident in the Valley.

A common symptom seen is foliage scorch/sunscald of new growth, sometimes first or second year needles too, generally on southwest exposures, and the southwest side of the tree.  This can be quite dramatic along roads and other exposed areas, with scorched needles visible from base to crown, particularly in Douglas-fir and grand fir, whose needles turn bright red.   Western redcedar and western hemlock are also affected, although the symptoms may be less dramatic, since the color change is more muted.

Wildfire is an accelerating problem across Oregon, with many potential impacts. One impact – smoke – can have many detrimental effects on communities including our physical and mental health, damaging our forest and agricultural industries, and slowing local economies.

Harmful smoke from wildfire happens somewhere in Oregon every year, and in years like last year, spares no part of the state.

Western redcedar bark and fronds

From Oregon through western Canada, western redcedar (Thuja plicata, WRC) has been dying in areas where it should be thriving, such as along streams and within closed canopies. The cause for this sometimes sudden and expanding dieback is currently unknown. Insects and diseases of WRC are typically secondary, meaning that they are not direct tree killers but are opportunistic pests and can only attack dead and dying trees. Redcedar can even tolerate endemic levels of bark beetles and stem decay for many years. These known pests have not always been found in dieback pockets nor have novel pests been observed.

The predominant theory for sudden mortality is that trees may be impacted by a changing climate, including increasing average temperatures and drought stress in the form of reduced and inconsistent precipitation. Even shaded sites along streams are at risk due to higher than usual average temperatures and reduced stream flow. Western redcedar is a species more sensitive to slight changes in abiotic conditions and may be crossing the lower limits of where they can thrive in some areas.

Looking for the cause

A team including Oregon Department of Forestry (ODF), Washington Department of Natural Resources (WADNR), the U.S. Forest Service (USFS), various university researchers and natural resource agencies are collaborating to collect locations to determine the distribution and possible cause(s) of dieback. We are mapping locations of dieback and monitoring some of these sites over the long-term.

We are now asking for your help in identifying sites of where dieback and tree decline is occurring. We are looking for pockets of dieback containing at least two mature trees with any of the following symptoms:

Do not report sites where the cause of dieback is known (e.g., mechanical damage, single sun-exposed trees, decadent old growth candelabra crowns or symptomatic trees in known root disease pockets) or trees with normal, seasonal dieback of older needles rather than whole-branch mortality.

Lastly, western redcedar may be confused with the other two species that we call “cedar”: incense cedar and Port Orford cedar (none are true cedar, which do not occur naturally in the PNW).The easiest way to identify western redcedar is by looking at the cones.

Western redcedar produces cones that look like woody roses, incense cedar has larger cones that split open like duck bills, and Port Orford cedar has cones that resemble soccer balls. Assist us in this effort to understand what is happening with this majestic staple of Pacific Northwest forests and urban areas.

Are you seeing these symptoms on western redcedar in your area? We need your help locating and reporting dying and symptomatic WRC across the species distribution!

It is shaping up to be another dry year.  Writing this in mid-month, we have seen unusually dry air and winds, creating fire conditions not usually seen until early summer.  We will likely see temperatures in the 80s and are under red-flag warnings last weekend.  In mid-April!   We could luck out, and get some serious precipitation in the next few weeks, but don’t count on it. 

We know “you can’t change the weather”.  But there are a few things under our control.  Here are some things to do in the face of a dry year.

Fire Prevention

ODF reports an unusually high number of fire starts this month.  The main cause has been back yard debris burns. 

Hold burnpiles until a safter time

A thing to do:  Do not set any debris fires this season (unless we get a significant weather change).  Instead, plan to cover piles and wait burn this fall after the rains start. 

Another thing to do:  Tell your neighbors about your choice to not burn now, and encourage them to do the same.  After all, an escaped burn next door is a very threatening fire.

Yet another thing to do:  Start taking fire season precautions now when working in the woods.  Carry your fire tools while working in the woods, doing storm clean up.  “Better late than never” not a good strategy here.

Fire Preparedness

The Labor Day fires created an awareness among residents of western Oregon about the potential of major fires.  The Extension Fire Program has created Fire Aware.  Fire Prepared., a 7-part series to help individuals and communities begin the work of being better prepared for wildfire.

A thing to do:  Watch the webinar series.  It is underway, and all previous sessions are available by recording at the Fire Program’s Online webinar guide.  https://extension.oregonstate.edu/fire-program/online-webinar-guide .

Another Thing to do: Take the preparedness actions presented in a to do list at the end of each session.  These include actions to harden your home against fire, as well as beginning to coordinate with neighbors.

Yet another thing to do:  That thing about coordinating with neighbors.  Encourage your neighbors to watch the Fire Aware. Fire Prepared. webinar series and begin a neighborhood planning process.


This is likely to be rough year for new plantings. Effective weed control will likely be more important than ever.  There may still time to touch up your weed control around your seedlings. Some weed control resources are here.   

Keep an eye on weed competion. It sneaks up on you!

A thing to do:  Check the weed situation in young plantings if you have them.  Treat if needed.  Be careful if using herbicides, as seedlings become more sensitive to spray when they come out of dormancy, as described in this post

Fire wood

As you do your winter storm clean up and piling remember that this is an excellent time to make firewood.  Firewood is best dried quickly, so early summer is great.  Unlike those precious boards you mill up for a “future project” which should be gently dried, firewood benefits from harsh drying conditions.

A thing to do: Cut wood early in the season and stack it loosely to catch the dry summer breeze.  This timely effort will help it dry quickly and burn cleaner in the winter.

A supply of dry wood can give satisfaction in many ways
