Emily Burkhart, a natural resources student, loves being part of the Oregon State community. As a member of the National Society for Leadership and Success, the Natural Resources Club, an intern at Avery Nature House and student arboretum specialist technician at Peavy Arboretum, she’s always reaching out and getting involved.

During the summer of 2017, Burkhart worked in Starkey Experimental Forest. Research in the riparian forest focuses on small mammals, cow and deer in relation to one another and the ecosystems they inhabit.

“When people think of ecosystem management and habitat relations, a lot of people think of large mammals and carnivores, but what a lot of people don’t realize is that it starts at a smaller level,” Burkhart says.

Burkhart spent two weeks checking about 200 traps every day to collect data on animals to learn about population dynamics in areas near water.

Species analyzed ranged from flying squirrels to jumping mice. The small mammals in these locations eat butterflies and their larvae as a food source, so researchers wanted to know population numbers and the roles they play in the conservation of species.

“Overall I processed and collected data on around 1,054 animals,” Burkhart says. “Once an animal was in a trap, we would tag its ears and collect data on its sex, age, weight, previous captures and reproductive state.”

Burkhart says she learned a lot from the experience and had a great time.

“At Starkey, I got to meet 25-year-old elk, explore Eastern Oregon and understand the importance of small species,” Burkhart says. “My amazing team made it a really great experience.”

Burkhart says she is grateful for her College of Forestry experience and how it opened her eyes to the world around her.

During the summer of 2018, Burkhart took part in a faculty-led study abroad experience to Malaysian Borneo. Back home in Corvallis, she enjoys spending time in the forest.

“We are so lucky to have the College Research Forests only 12 minutes away from campus.

By working at the arboretum, I really learned how these managed forests operate, and how much it gives back to us in research, recreation and pure happiness,” Burkhart says. “People really need to go check out the arboretum at least once in their life because one visit can leave such a positive, everlasting impact.”

Renewable materials student Cody Knight is a recipient of three scholarships: the Lois & Dick Kearns Scholarship, John R. Snellstrom Scholarship and the Friends of Renewable Materials–Roseburg Forest Products Wood Science and Engineering Scholarship. Before coming to Oregon State, Knight served in the military.

The financial support he receives and his experience in the military inspired him to serve others through his work in the renewable materials program.

“My military experience left me asking a lot of questions about humanity, sustainability the western world and material possessions,” Knight says. “I want to create products from renewable materials that aid in sustainability.”

Knight, who grew up in northern Idaho, remembers spending summers at the lake, sleeping in log cabins.

“There, it was easy to appreciate the beauty of nature,” he says. “I want to preserve that beauty and those kinds of experiences for future generations.”

He’s working to reach his goals through hands-on learning activities outside the classroom. Knight has participated in undergraduate research with Arijit Sinha, associate professor of renewable materials at Oregon State. Knight is helping conduct testing on Freres Lumber’s new mass plywood panel product.

“I was also selected for the Research and Extension Experience for Undergraduates (REEU) program,” Knight says. “This is a three-month long mentored research program with students at Oregon State and from colleges across the United States.”

Knight says his research will evaluate the shear strength of plywood and oriented strand board (OSB) after it has experienced varying degrees of temperatures and cooling times to get a clear picture of the mechanical strength of both products in the event of fire and seismic activity.

“The importance of this is plywood and OSB are typically used in residential housing for the exterior sheathing, which provides lateral support and stability for the structure,” Knight says. “Little research has been done to test their behaviors under these conditions, and I’m excited to find some answers.”

To solve a large problem you often have to come at it from a different angle. It is an approach Ian Munanura, assistant professor of nature-based tourism and human well-being at Oregon State, took after starting his research in human wellness and forest landscapes.

“In my research, I explore aspects of human well-being constraints and how they influence the health of forest landscapes” Munanura says.

“I also ask questions about how forest landscapes benefit humans. For example, how can tourism on forest landscapes improve human wellness, strengthen the resilience of forest communities and reduce negative human impact on forest landscapes?”

To answer this question, Munanura conducts a series of surveys and interviews of forest adjacent communities in Oregon, Rwanda, Uganda and Indonesia. He also hopes to expand his research program to Tanzania and Malaysia. To broaden the experiential learning opportunities for College of Forestry students, Munanura will use his international research network to deliver summer study abroad classes in countries where he has active research programs.

During his research interviews, Munanura asks questions such as: What is the nature of adversity stressing the livelihoods of families in forest communities?

How do families in forest communities function during adversity? What are the strengths (or vulnerabilities) of families in forest communities that could enable (or challenge) them to cope with adversity and maintain wellbeing?

How do the vulnerabilities of forest communities negatively affect forest landscapes?; and many others. Munanura thinks the answers to these questions will contribute to the understanding of important factors responsible for human-wildlife coexistence.

“Once we unpack the complexity of human health constraints and identify the aspects of those constraints that threaten our forest landscapes the most, we can adapt nature-based tourism programs to benefit communities, people and our forests,” Munanura says.

The inspiration for looking beyond the material aspects of human well-being came from Munanura’s own life experiences and growing up with limited access to material resources. Munanura says his family’s wellbeing recovered from destitution when his mother became spiritually active.

“Her mindset and emotions changed, and it enabled us to function better as a family despite limited access to material resources,” Munanura says. “In my work over the past 15 years, I have paid more attention to material wealth as a solution to improve the wellness of humans and forest landscapes. I strongly believed that degradation of forest landscapes was caused by lack of jobs and financial resources.”

However, Munanura says that attempts to address forest degradation by providing jobs and financial resources have shown little success. His research in Rwanda confirmed forest degradation is largely influenced by the most economically empowered residents in nearby communities.

“That challenged me to look at my own personal experiences. I realized there is more to improving human and forest wellbeing than money,” Munanura says. “Perhaps, there are non-fi nancial aspects of human well-being that have the potential to strengthen forest communities and forest landscapes.”

Munanura says his research is inspiring his students and helping them understand the limitations of the poverty driven narrative of forest landscape degradation.

“I encourage my students to think broadly and consider how human adversity, emotional, social and material resource constraints could impact the health of forest landscapes,” Munanura says. “Forest managers and other natural resources professionals are better served with a nuanced understanding of human constraints, how they impact the health of forest landscapes, and the potential solutions from nature-based tourism that can improve overall human and landscape well-being.”

Klamath County Forestry Extension Agent Daniel Leavell began his forestry and fire career in early 1973 at the Forest Fire Laboratory in Riverside, California, and continued later that year at the Oregon State campus. He earned a bachelor’s degree in 1977 from OSU, and has been working and continuing his education in both industries ever since.

Leavell, who also holds a master’s degree from OSU and a doctoral degree from the University of Montana, started his current extension position with the Oregon State College of Forestry in 2014 and hit the ground running in Klamath and Lake Counties.

“We’re all working together to reach a common goal,” Leavell says. “It’s been extremely satisfying for me to play a role in these efforts – especially to see results happening on the ground.”

Klamath Community College Partnership

In 2014, the main fire district in Klamath Falls and Klamath Community College (KCC) began talking about the possibility of developing a formal program and facility that could support the training and education of first responders in the fields of fire, emergency medical services, law enforcement and more.

“We all agreed it was a community need and wanted to pursue it, and I offered assistance,” Leavell says.

Leavell was involved in wildland firefighting from 1978 to 2012 and with volunteer structure fire departments from 2006 to 2016. This experience allowed him to bring together other partners including the Oregon Department of Forestry, U.S. Forest Service and the Oregon Air National Guard Fire Department at Kingsley Field in Klamath Falls.

Leavell says it is important for first responders to attain national, state and local certifications. Many in emergency services also desire academic credit, but these are not required to obtain certified skills needed for the job. However, academic credit and degrees provide a competitive edge for job searches. Skills and experience count.

“Many first responders want certifications and academic credit,” Leavell says. “So we set up an organization to do that.”

The Klamath Basin Public Safety Training Center began with the goal of offering participants a two-year degree with options in structure and wildland fire, emergency medical and law enforcement.

Oregon State and KCC signed an agreement to test the concept and designed a curriculum for a two-year program focused on the basic academies of medical and fire sufficient to obtain certificates and credits. As proof of the concept, the program organized, created and implemented a structure fire academy during winter and spring terms in 2015 and 2016. The 14-week program involved 30 future professional, structure firefighters.

“They went through live fire training, ladder training and other exercises,” Leavell says. “Practical skills, scientific education and leadership training were also implemented, and at the end of the program they earned 12 academic credits and state certificates for structural firefighting.”

Leavell says the next step is to formalize the transfer program between KCC and Oregon State.

“This was needed,” Leavell stresses. “It will really benefit small communities with busy fire stations.”

Managing landscapes

One reason Leavell came to work in Klamath County was because he knew there were forward thinking forest managers working in and near the Fremont-Winema National Forest.

“The community here really works together,” Leavell says. “And when I got here, a group of private landowners and public land managers had been meeting and agreed to start work on a very large but successful project.”

Together, Leavell and the other managers were able to create maps and make risk assessments for 30,000 acres of private forest and 110,000 acres of National Forest.

“Within a year of completing the mapping, we were awarded $4 million in grants to begin implementing the projects we found were necessary during the mapping process.”

Throughout the process, Leavell worked one-on-one with landowners to help them create and implement management plans and pick projects that would benefit each forest.

Leavell says public and private land managers were able to work together to conserve resources during thinning efforts.

“It’s a win-win situation for everyone,” he says. “If a landowner can get grant money it’s easier for everyone to get a project done, and our reward is better management for the health and safety of the forests, communities and those responding to disturbances.”

Leavell and his team hope to publish the results of the project so their strategies can be implemented statewide.

Making a difference

These projects and more make working for the Oregon State Forestry and Natural Resources Extension Service in Klamath and Lake Counties a fulfilling experience for Leavell. He hopes to see even more results in the future by bringing people together to make our forests and communities healthier.

“I love to sit down at the table and talk to people to see how we can overcome barriers, capitalize on our strengths, shore up our weaknesses and see how we can come together for a common goal that really gets results,” Leavell says. “Extension is in a unique position to facilitate, coordinate and bring partners together to fulfill our mission, which has no underlying agenda other than to benefit the community.”

Large wildfires can devastate the landscape, destroy structures and threaten communities. Once they’re extinguished and the direct threats are gone, the general public often moves on and breathes a little easier. However, Kevin Bladon, assistant professor of forest hydrology at Oregon State, says the effects of large wildfires on water quantity and quality can last for decades.

“Smaller, low severity fires can actually have positive outcomes for aquatic ecosystems,” Bladon says. “However, the larger fires, which we’ve seen more of in recent years, are the ones that cause us the most problems in terms of impacts on water,” Bladon says. “Fires used to be more frequent and less severe, but because of fire suppression and current forest management approaches, there are a lot more contiguous fuels in our forests. When combined with a warmer, drier climate this has increased the occurrence of large wildfires in many parts of the western U.S.”

Bladon says high-severity fire can increase annual streamflow, peak flows and shift the timing of snowmelt to streams to earlier in the year. Additionally, large fires can increase temperatures, sediment and nutrients in streams, which can negatively impact aquatic ecosystems and recreational value.

The sediment and nutrients in headwater streams can also travel downstream and into community drinking water sources.

“While our drinking water treatment plants can, and do, remove sediment, nutrients and other contaminants from our water after wildfires, the question is, ‘How much are we willing to pay for this?’ These are expensive costs that get passed to taxpayers for many years after a fire,” Bladon says.

So far, Bladon’s studies have been conducted in Oregon, California, Colorado, Tennessee and Canada. As large wildfires continue to occur in the West, he plans to keep his eyes and research on the west side of the Cascades.

“Historically, there haven’t been a lot of fires on the west side of the Cascades compared to east side forests,” he says. “But they are appearing more and more, and the potential impacts on our water supply is something researchers need to continue to investigate.”

Bladon says it’s an exciting time to be studying hydrology as it relates to wildfire because the scientific community and the public are striving to understand how large wildfires impact our water supplies.

“Oregonians tend to be very proud of our water, healthy rivers, recreational opportunities and our many breweries, to name a few things,” Bladon says. “Given that two-thirds of our water supply originates in forests, it’s critical to protect those things that make our state such a great place.”

Logging on steep slopes is the most hazardous environment for a forest worker according to John Sessions, University Distinguished Professor and Strachan Chair of Forest Operations Management at Oregon State.

Sessions is part of a team of investigators researching innovative technologies to improve logger safety on steep slopes. Other research team members include Woodam Chung, Ben Leshchinsky, Francisca Belart, Tamara Cushing, John Garland, Jeff Wimer and Brett Morrissette from the College of Forestry and Laurel Kincl from the College of Public Health and Human Sciences. The three-year project is funded by the National Institute for Occupational Safety and Health.

“Logging has consistently been one of the most hazardous industries in the U.S. It has a fatality rate 30 times higher than the national occupation average,” Sessions says. “Increasing mechanization of felling and skidding has removed workers from the forest floor in flat terrain, however, workers remain on the forest floor for felling and extraction in steeper terrain.”

The study examines strategies for replacing forest workers on forest slopes with tethered and non-tethered felling, forwarding equipment and combining mechanized felling with traditional cable yarding methods. The research would improve safety in the steep forest workplace.

Preston Green, a graduate research assistant on the project, focuses specifically on harvesting productivity, cost and environmental impacts of cable-assisted harvesting systems.

“I conduct detailed time studies of harvesting, forwarding and cable yarding equipment, with and without the use of cable-assistance, to quantify the differences in harvesting system productivity and environmental impacts,” Green says.

Green says he first became interested in cable-assisted harvesting as an undergraduate forest engineering student at Oregon State. Industry internships peaked his interest in the subject, and Green decided to attend graduate school to conduct additional research.

“My family has worked in the timber industry for four generations, and I’ve seen the long-term effects that logging injuries can have on families and communities,” Green says. “We’re striving to make improvements in the industry, not just improve statistics. We are dealing with real people that live and work in our communities.”

The project has 15 collaborating companies. The research team includes forest engineers, forest operations specialists, occupational health and safety specialists and a geotechnical engineer.

“Due to the steep slopes throughout Oregon’s forests, we believe the introduction of cable-assisted harvesting equipment can be a paradigm shift that will improve safety and economic competitiveness for the industry in Oregon and beyond. It will provide the ability to implement safe forest restoration practices across the difficult terrain in many public forests,” Sessions says. “Our research results and the widespread interest about the study from forest owners, logging contractors, equipment manufacturers, and state and federal agencies suggest we are on the right track. This technology and our research will likely save lives.”

The new George W. Peavy Forest Science Center will be unique, not just because of the atmosphere, but because the building will also be a living laboratory.

This living laboratory is one aspect of the SMART-CLT project, led by Mariapaola Riggio, assistant professor of wood design and architecture at Oregon State. The goal of the SMART-CLT project, which stands for “Structural Health Monitoring and Post-Occupancy Performance of Mass Timber Buildings,” is to analyze critical factors impacting the performance of cross-laminated timber during its service life, and develop protocols to monitor these factors in buildings. The SMARTCLT project will study cross-laminated timber on a small and large scale, and will be applied inside the Peavy Forest Science Center, soon to be the new home of the College of Forestry.

“Our project is looking at what is sometimes deemed as ‘serviceability of a structure,’ which includes everything from how the material vibrates, which can be a limiting factor in terms of design for long spans; deflections of the material and acoustics. We’re looking at a variety of factors,” says Evan Schmidt, outreach coordinator at the TallWood Design Institute (TDI).

Riggio says the study is multidisciplinary. The research team involves architects, engineers and industry professionals who will analyze the project from a variety of perspectives. The project is funded by TDI, a collaboration between Oregon State and the University of Oregon and the nation’s leading research collaborative focused on advancing structural wood products.

“It’s not just how the system and the building performs in terms of standard and code requirements, it’s also how it is accepted or how it contributes to the well-being and the comfort of the occupants. That’s why it’s important the project involve a number of partners,” Riggio says.

The living laboratory will provide information for many generations to come.

“Usually research is just a limited amount of time, but this project will last as long as the life of the building,” says Riggio.

The sensors used to monitor the building are a unique aspect of the project, an original idea which will help researchers see what is happening inside the materials of the building.

“We want to understand which approach can be the most effective when analyzing the overall performance while delivering meaningful and valuable information,” says Riggio.

Schmidt says the sensors outfitting the building will monitor the indoor environment, temperature of the mass timber elements, moisture content inside of the wood at various depths and locations, vibration, post-tension loss in the wall systems and more. There will be about 176 different sensor locations.

“We’re measuring a bunch of performance parameters relative to the environment,” Schmidt says. “It’s important to capture because wood is not an inert material. The way it interacts with the environment will impact the way it performs, long-term and short-term.”

While the project will last the life of the building, researchers will also monitor short-term insights during construction to understand the immediate effects.

Researchers believe this project will provide a better understanding of how best to promote the use of mass timber in construction in the U.S.

“We need flagship structures,” Schmidt says. “We need to conduct research during and after construction. The combination of the two will make the public aware and excited about the benefits of mass timber buildings.”

Junior Tourism, Recreation and Adventure Leadership student Chris Galbreath has a passion for the outdoors, but wasn’t sure what he wanted to do when he landed at Oregon State. When he learned about the recreation management field in an introductory course, he felt a spark.

“I could see myself in a position like that, and decide that’s what I wanted to do,” Galbreath said.

To further explore his potential field, during spring term 2017, Galbreath participated in the job shadow program, facilitated by the College of Forestry’s Office of Student Resources and Engagement. Job shadows are usually short, one-day experiences during which students follow professionals in their chosen field to learn more about what they do.

“The office helped me explore what kind of job shadow opportunities were available, and I decide to job shadow an interpreter at the Yaquina Head Interpretive Center.”

From there, Galbreath communicated with the professionals there, who invited him out for a day to learn more about their positions and the work done at the lighthouse’s protected area.

“The day I went, there was a school group coming in, so I got to see how they deal with those as opposed to the general public,” Galbreath says.

He also explored tide pools and hiking trails.

“Before I went to do the job shadow, I didn’t have an idea of what they do, but while I was there I got to see how they manage people and how they run the business. It gives you a good insight into what this particular section of the job world looks like, and then you can reflect on that,” Galbreath says.

Galbreath enjoyed the field of interpretation so much that he spent the summer interning with the Oregon Department of Forestry as interpreter at the Tillamook Forest Center.

“My job there was to learn material about the forest and pass that on to the public so they understand it and can go have a great time out in the forest as well,” he says.

Galbreath was the first student to participate in the job shadow program, and there are many opportunities available.

Brooke Harrington in the Office of Student Resources and Engagement says the job shadow program is a great way to explore future employment opportunities.

“These opportunities are a way to start exploring different career paths, make important industry connections and see how classroom work can create success in the work place,” Harrington says. “The goal of this program is to connect students with short-term opportunities that can help them make important career and academic decisions.”

During stints in the military and his 20-year career as an emergency room nurse, forest management student Christian Vedder spent all of his free time in the woods climbing mountains or rolling over trails on his mountain bike. When the stress began to get to him, his wife suggested he look for a career that would allow him to work outside.

The Portland native began to look into the idea of studying Forestry at Oregon State.

“I was always fascinated by the subject of forestry,” says Vedder. “I attended logging sports competitions as a spectator when I was a kid, and my book shelves are filled with books about Northwest logging history.”

He reached out to Professor John Sessions, who invited him to Corvallis to visit the College of Forestry and learn more about the program. After that, he was hooked and decided to take a leap of faith, quit his stressful job in the ER and pursue his new dream.

Once enrolled at Oregon State, Vedder jumped into opportunities like the Forestry Club and Student Logging Training Program, which provides an opportunity for students to experience real-world logging applications on the McDonald-Dunn College Forest. Through the process, the student crew becomes proficient at using modern technology and equipment to aid the logging process.

Vedder knew it was important to get involved and connected even though he was learning and working side by side with people half his age.

“I was intimidated at first,” Vedder admits. “And I think other students maybe felt uncomfortable with me, but now that we’ve taken some classes together, we get along and they joking call me ‘the old man.’”

Vedder doesn’t feel old. He works part-time as an arborist and enjoys the physical aspects of working in the forest.

“When you’re logging, you have to be very safety conscious,” Vedder says. “You have to have your head up all the time and use common sense and be aware of your surroundings. I love to be hyper focused, and I think a lot of loggers thrive on that aspect of the job.”

Vedder says the hands-on learning of the Student Logging Program combined with strong theoretical learning in the classroom is a perfect combination.

“When you’re in a classroom learning about forestry, you don’t always understand all the variables at play,” he says. “In the field, you have to decide which trees to utilize and which are easiest to extract. It’s not always cut and dry.”

This summer, Vedder stayed in Corvallis to attend class, but he still found time to get outside recreationally.

“There will always be mountains to climb,” he says.

Vedder plans to begin studying for his master’s degree in forest management soon. In the future, he is interested in consulting with property owners on land management issues and helping to shape management policy, and he wants to encourage others to chase their dreams and persue their career goals.

“These days, we all get caught in ruts in our lives, and we get too complacent,” Vedder says. “People stay in jobs they hate because they have bills to pay and mouths to feed and it’s difficult to break out of their routine, but I’ve learned that money is never going to buy you any kind of fulfillment. You need to love what you’re doing, and the money doesn’t matter.”

Scott Leavengood, director of the Oregon Wood Innovation Center, began his career at Oregon State twenty three years ago as a Klamath County extension agent. Back then, he answered many phone calls from county residents asking what they could do with their western juniper trees.

The wood is strong and durable, and extremely common in Eastern Oregon.

Due to changes in land management practices, wildfire suppression in particular, western juniper acreage in the western United States has increased dramatically in the past 100 years. Thinning juniper stands helps restore rangelands and habitats for animals like the sage grouse, but until recently, there’s been no practical application for the use of this resilient and durable wood species.

“A lot of people were interested in using western juniper in building projects, but for use in structural applications, engineering design values have to be published,” Leavengood says.

Throughout the years, inquiries about western juniper continued, but there were no funds to study juniper-based materials and their market potential until 2015.

USDA Rural Development, the Oregon Department of Transportation and Business Oregon provided funding for juniper testing. Sustainable Northwest managed the project and graduate student Byrne Miyamoto stepped in to do the legwork for the project including small-scale bending, compression and shear tests.

“I spent the entire first summer of the project in the wood shop just cutting samples and making sure there were no defects,” Miyamoto says.

Juniper is a species often riddled with knots and imperfections, making the work difficult, but Miyamoto and Leavengood prevailed and testing was conducted in the summer of 2016. A few durability tests will continue in years to come.

“I have some posts set up in Yaquina Bay in Newport, so we’ll see how well it holds up there and if shipworms attack it,” Miyamoto says. “We examine the samples one a year, and so far we have not seen any attack.”

The results of the western juniper certification project will be published in the National Design Specification in 2018.

“Many key market opportunities couldn’t exist for juniper without published values,” Leavengood explains. “We think that the ability for engineers to use juniper for things like sign posts and guardrail posts will have implications for everything from land management to job creation.”

Miyamoto is focusing on finalizing the focus for his Ph.D. research at Oregon State this fall, and he looks forward to seeing western juniper in use someday soon.

“I’ve spent two years of my life coming up with five values that engineers will be able to use to decide if juniper can be helpful in their projects,” he says. “I’ve spent a lot of time with my juniper samples in the lab, but soon I hope I’ll be able to see the values we produced in use and say, ‘that was me.’”
