New forest inventory method a potential game-changer.

If you need to estimate the value of a forest — whether a plantation of Douglas-fir or a small woodlot — experts in mensuration (aka biometricians) can give you a time-honored method. The traditional process of sampling plots, the measuring of tree heights and diameters, allows an estimation of resources at the landscape level. It works well enough; a similar process also served the ancient Romans.

However, there is a price to be paid. Measuring a small portion of the trees, say 2% to 4%, leads to uncertainty. Moreover, it is cumbersome to replicate the process for future analytical purposes.

Now Chu Qi, a graduate student in the College of Forestry’s MARS lab (Management, Algorithms, and Remote Sensing), has developed a powerful new method to dramatically reduce the uncertainties associated with capturing a forest inventory. The technique speeds up the analysis and creates a robust 3-D dataset for ongoing forest assessment.

Using terrestrial laser scanning (TLS) data from a stand in the McDonald- Dunn Forest near Corvallis, Qi and Bogdan Strimbu, Qi’s adviser and an assistant professor in Forest Engineering, Resources, and Management, created an algorithm that extracts information about forest structure.

For forest inventory purposes, “we identify what is stem and what is not stem,” says Strimbu. But the full point cloud dataset (the collection of points recorded in 3-D by a scanning device) offers a 360-degree picture of the forest environment, everything from the ground to the canopy. Consequently, it can provide details to understand the forest’s multiple aspects, such as understory and canopy conditions, biodiversity and carbon storage.

“We wanted to save on the labor of doing a forest inventory,” says Qi. “We used new technology for analyzing point cloud data. It had not been applied to a forest before. It was a challenge to separate the points for the stems from everything else in the forest. There’s a lot of ‘noise’ in the data.”

Strimbu is working with the OSU Research Office to file a patent. “The ballgame has completely changed,” he says. “If you rescan the stand in the future using the same procedure, you’ll find many of the same trees. With point clouds, you can study changes that are not measured traditionally.”

Conventional mensuration techniques dominated forestry in the 20th century. A turning point with the advent of airborne remote sensing in the late 1970s when the Landsat program generated the first broad glimpses of forest landscapes. However, the deployment of active sensors, such as LIDAR on aircraft and land-based platforms, created the path for Qi’s and Strimbu’s innovation.

“Imagine that you have created a set of plots for conducting a conventional estimate of timber volume,” says Strimbu. It might take all day to visit each plot and create a record of tree heights and diameters. In the same time, you could walk with a TLS device that creates a continuous point cloud of the forest environment, process the data and run it through the algorithm developed by MARS to estimate volume.

“You still have a sample, but instead of being based on 2% of the trees, it would be based on 25%,” Strimbu adds.

Tests of the algorithm have shown it to have 100% “correctness,” meaning that everything identified as a tree is a tree. Moreover, the algorithm successfully found 95% of the trees.

“We have a wealth of data and need to extract information for relevant measurements,” says Strimbu. It takes a strategy to extract relevant information using traditional forest inventory. For other purposes, point clouds offer the raw data from which extra information, unplanned initially, can be later computed.

For example, if one needs to know how much coarse woody debris is in the forest, current practice calls for a cruise dedicated to this purpose. However, the same estimates can be obtained from an existing cruise that was implemented using point clouds.

The advancement is not the first to come from Strimbu’s MARS lab. He and Qi teamed up earlier to produce an algorithm that uses point cloud data for a single tree to replicate its exact shape and volume. The approach is particularly useful for calculating the optimum cutting pattern for a high-value tree.

Strimbu also has a patent on an algorithm that determines geolocations in point cloud data. Their research was supported by a grant from the US Department of Agriculture.

Working at the crossroads of industry and community.

Assistant Professor in Forest Policy, Mindy Crandall, grew up in the Oregon Coast Range town of Otis on the edge of the Siuslaw National Forest. For recreation, she and her family camped in clear-cuts, rode dirt bikes and hiked steep trails through towering Douglas-firs.

“It was kind of my playground. There were no other kids close by. It’s the most beautiful place in the world,” she says.

And yet something nagged at her, a question that crystallized after she moved away. Why was it, she wondered, that the national forest looked so different from nearby privately-owned land?

Exploring that question led her to an undergraduate degree from the College of Forestry and a master’s and Ph.D. in Applied Economics from OSU (“I’m a triple beaver”) in 2016.

While she found the biology and ecology of forests fascinating, it was the human element that captured her imagination. “It’s all about people and their interactions with forests,” she says.

Crandall moved across the country to pursue that topic in a tenure-track position at the University of Maine (before getting her graduate degrees, she had worked as a VISTA volunteer in Maine for two years). She returned to Oregon State in January 2020.

“What motivates my research is the intersection of forests, rural communities and working landscapes. That’s where my heart lies,” she says. “How can we sustain a proper forest industry, and how can rural communities survive? These are treasured places of knowledge and experience. Somehow we need to figure out a way for all these things to work together. What are some of the slam-dunk things that are going to help rural places?”

In her efforts to illuminate the social and economic systems that shape forest-based communities, Crandall has looked at the forest industry workforce, alternative uses for biomass, and the relationship between the landscape and land management decisions.

For example, in Maine, she led surveys of businesses and youth to evaluate students’ interests in developing skills that match with forest industry employer needs. Crandall’s team found that students’ skills and expectations aligned with the culture of future potential employers.

In another study, Crandall looked at the relationship between regional landscapes and forest management. Her team identified factors such as tourism, exurban development, infrastructure, and commuting patterns that shape private landowner decisions and affect surrounding communities and landscape structure.

A project that harkens back to Crandall’s youth is “near and dear to my heart,” she says. The Rural Youth Futures Project surveyed high school students in two rural counties — Piscataquis County, Maine, and Coos County, Oregon — and was co-managed by fellow College of Forestry alumna Jessica Leahy. The goal was to evaluate the needs and opportunities facing youth growing up in rural forest-dependent communities.

“This comes out of my own experience growing up in the Coast Range, where there didn’t seem to be a lot of opportunities,” says Crandall. “We wanted to look at how kids think about the economy and the environment, how they perceived their communities, their outdoors, and whether they wanted to stay in rural areas or move away.”

An advisory committee of community leaders in both states helped to determine the questions and connect with schools. The project generated more than 2,000 survey responses. Crandall and her team found that youth have high educational aspirations and a high degree of place attachment to the outdoors. Publications are in process.

“Mindy wants to have a positive impact on rural communities that are challenged by the changes affecting forest-based economies,” says Claire Montgomery, retired chair of FERM and a forest economist. “In all my work with her, her concern for fairness and justice shines through. That passion is manifested in her research program and her commitment to programs that support diversity, equity, and inclusion.”

A prime example focuses on gender in forestry education. “When I started at OSU 20 years ago in forestry,” says Crandall, “it was about 10% women students, and it’s still about 10% women. Why have we made no progress? Female undergrads are often the only women in their classes.”

Conversations with Maine colleagues and students led to the formation of a group called Supporting Women in Forestry Today, or SWIFT. The group held social and professional events, which became places where people to get to know each other. Education, networking and strategizing for undergraduate women were its priorities. Although the pandemic has curtailed face-to-face gatherings, Crandall is considering ways to apply the lessons of SWIFT in Oregon.

In upcoming research, she is collaborating with Jeff Kline, a U.S. Forest Service economist, to study the community impacts of severe wildfire. “I loved living in Maine, but I’m happy to be back home in Oregon,” she says. “The landscape and politics of the West are so interesting — public lands, the rural landscape. It’s so fascinating. There’s so much to explore.”

Online graduate certificate offers a competitive edge during job hunt.

Getting out of the military after a long career of service is daunting, but thanks to Oregon State University Ecampus, Andrew Carrier, who began his military service after receiving his bachelor’s degree from the University of Tennessee, had the opportunity to expand his knowledge in his chosen field of urban forestry before he stepped into civilian life.

“Online programs are much more feasible for busy active duty members,” Carrier says. “After researching numerous institutions, I found the OSU online master of natural resources and graduate certificate in urban forestry programs. I was sold on the program based on the ability to form a solid base level knowledge in urban forestry and then easily transition to the master’s program without having to go back and take GRE.”

The OSU graduate certificate in urban forestry prepares students to think scientifically and strategically, at a time where adult learners are looking for alternatives to in-person educational opportunities. Students learn to effectively apply the principles of urban forestry, green infrastructure, planning, policy, management and leadership to the management of urban forests and urban forestry programs.

The certificate is unique and the first of its kind offered online. Courses are delivered through OSU Ecampus – a national leader in online education. No other university in North America currently offers a graduate urban forestry education in this flexible, accessible format.

Carrier finished the certificate program last year and used the program to transition to the master’s of natural resources program. He credits his online OSU education experience in helping make him a desirable candidate in the natural resources and sustainability career fields. In February of 2020, Carrier was hired as a tree inventory technician by PlanIT Geo, a natural resources consulting firm based in Denver.

While reflecting on his experience, Carrier says he enjoyed his classes and the work of Senior Instructor Paul Ries.

“There was a really good balance in the program of academic overviews, important case studies and daily application,” Carrier says.

Ries, who helped create the certificate program, says his students are dedicated and come from a diverse set of backgrounds. “Some, like Andrew, are transitioning into an urban forestry career, while others are already practicing urban foresters looking for advancement,” he says. “One of the most rewarding parts of my job is helping mentor these professionals and watch them grow in their careers and take on new challenges.”

Two new buildings for the future of forestry.

The Oregon Forest Science Complex (OFSC), primarily made and grown in Oregon, highlights an entirely new way of thinking about building and design. The complex is comprised of three buildings; Richardson Hall, the new George W. Peavy Forest Science Center (PFSC) and the new A. A. “Red” Emmerson Advanced Wood Products Laboratory (AWP). The new additions total 95,000+ square feet and are a great example of how sustainably managed forests can be used to create beautiful buildings out of wood and establish a connection with outdoor landscapes.

Thanks to the vision, support and work of former dean Thomas Maness, the leadership of former interim dean Anthony S. Davis, the State of Oregon, OSU Foundation and numerous donors, faculty, students, staff, and alumni, the complex provides a learning environment that is one of a kind.

The complex features 20 classrooms and several computer rooms and laboratories, including the FERN Student Center and the Peavy Arboretum. In these spaces, faculty, students and researchers can participate in active learning and discovery while utilizing cutting-edge technology.

The OFSC features innovative materials, from Accoya wood cladding to View dynamic glass windows. By utilizing these products and others, like cross-laminated timber and mass plywood panels, the project highlights how mass timber and structural wood products building solutions can increase the value of Oregon’s natural resources and enhance our communities.

Like most seniors in forest engineering, Ethan Harris had a plan for his capstone project. On Starker Forests land in the Oregon Coast Range, he would survey a stand, appraise its timber value, develop a harvest plan and coordinate with mills and truckers.

But when stay-at-home and social distancing orders came down from the governor’s office in March, Harris had to change course. Timber cruises and other survey work were cancelled. Instead of meeting in person to pore over maps and review details, the project team met virtually through Zoom.

Harris’ most significant hurdle, he says, was to get over his dismay with the setback. Woodam Chung, Stewart Professor of Forest Operations, helped Harris to find available data and complete the project.

Another senior, Wade Christensen, had a similar experience for his capstone. Help arrived in the form of remotely sensed LIDAR data from a leading expert in the field, Bogdan Strimbu, assistant professor in Forest Engineering, Resources and Management. Allowing for differences between direct observation and point clouds, Christensen was able to estimate timber volumes and complete his work.

Both Harris and Christensen graduated on time, but they are only two examples of the stressful scramble brought on by pandemic restrictions last spring. Adjusting capstone projects, jumping into remote classes, recalibrating internships, filling gaps in students’ resources — all fell to faculty, advisors and support staff.

What they accomplished, says Christensen, “was monumental.”

For Nicole Kent, Manager of Advising & Academic Relations for the College of Forestry, the shift became all consuming. She and her team make sure that the college’s nearly 1,000 undergraduates get the courses and experiences they need. They also conduct student orientations and other events.

Only about half of those students are on the Corvallis campus. Others work at OSU Cascades in Bend, at Eastern Oregon University in La Grande or through Ecampus. “We were already doing a lot of remote teaching. That gave the college a head start in adjusting to the pandemic,” says Kent.

Most students in Corvallis are there because they want to learn in person — in the forest, on field trips, in labs, face to face. When restrictions were imposed in March, students saw internships and other work-experience opportunities evaporate. Some courses were cancelled and others shifted to the computer screen.

Although some students had already completed their internships, others had planned to do so during the spring term. “The absence of those experiences was challenging for some,” Kent adds.

Nevertheless, the College of Forestry prides itself on producing work-ready graduates, so advisors and faculty shifted gears to find alternatives. They determined what courses would provide the required learning outcomes and kept students on the path to graduation.

“I can’t say enough about how wonderful the Student Services team is and how hard they have worked,” says Kent. “They were all at home working remotely. They stepped up to show such great care and compassion for our students.”

Those efforts included finding financial help when income had suddenly dried up. The OSU Foundation led an effort that saw over 3,000 donors contribute over $1-million for Beavers Care, an initiative to make a difference for OSU students, faculty and staff in urgent need of emergency support. College staff navigated the federal CARES Act to determine who was eligible for assistance and who was not. Staff also identified additional university resources to help fill gaps in their personal lives, such as access to groceries and medications.

Staff in the college’s IT office made extraordinary efforts to make sure all students had access to computers and the internet at home. During the same weeks, the college was moving into the new Peavy Forest Science Center building. IT was assisting students with Zoom meeting software, loaner computers and off-campus access to computer labs.

“All the work they were doing behind the scenes made a huge difference,” says Kent.

Faculty members also stepped up to help each other. For example, David Stemper, senior instructor in Forest Ecosystems and Society, sent an invitation to all faculty in March offering to assist people who were new to online teaching. He has been teaching remote courses for the college since 2008.

Among the challenges of teaching in a remote environment, he says, are managing discussions, monitoring student performance and grading. “The biggest challenge is that, since you don’t face students one on one, you have to put in extra effort to add a personal, thoughtful touch to all correspondence.”

Stemper says a handful of people responded to his offer. One was a simple observation from Bruce Shindler, OSU professor emeritus whose environmental interpretation course provided Stemper with his first college teaching experience in 2001. “He told me that ‘you and people like you are why I enjoy working for the College of Forestry,” says Stemper.

Throughout spring term, OSU and the college communicated with students, sending updates about available resources and helping people who were struggling with isolation. “It sounds trite,” says Stemper, “but it revealed this strong learning community that we all have. It showed a lot of collective character on the part of OSU.”

As a forest social scientist, Tom DeLuca has worked in Sweden, the United Kingdom, China, the Rocky Mountains and other far-flung places. He has focused on elemental, environmental and silvicultural cycles that link forest productivity to the soil ecosystem and human activity. He has served in leadership positions at Bangor University in the U.K., the University of Washington and University of Montana.

But when the chance came to advance the legacy of his friend and colleague Thomas Maness and direct one of the world’s leading forestry programs, he jumped. “I’ve known Oregon State as the premier forestry program in the nation, if not the world,” says DeLuca, who succeeds Maness as the Cheryl Ramberg-Ford and Allyn C. Ford Dean of the OSU College of Forestry.

In 2012, at about the time that Maness became dean, DeLuca was hired as director of the School of Environmental and Forest Sciences at the University of Washington. “We gave talks at the same professional meetings, hit it off and became friends.”

DeLuca says he and Maness shared similar perspectives about the future of forestry. “Thomas started things in motion as dean that I’m excited to pick up and advance. For example, if OSU becomes the steward of the Elliott State Forest, we would have a tremendous opportunity to push the limits of what sustainable forest management looks like on the landscape. How can we meet our needs for fiber without degrading habitat?

“I see forestry as a key element of a sustainable future on Earth. Our survival as a species ties directly to forests and all of the attributes that we depend on — whether it’s clean water, air, forest products or diversity of species.”

As a boy growing up in Madison, Wisconsin, DeLuca practically lived outdoors. His family had two farms in the badger state and one in Colorado, and he learned about the dawn-to-dusk demands of agricultural work. They made frequent backpacking trips to Idaho and Montana. His strong connection to the woods and the West motivates him today.

“I spend as much time outdoors as I can. I love to be in the woods. I do a fair amount of trail running, skiing and cycling,” he says. As young parents, he and his wife Denise took their three sons Vince, Emile and Henry on outdoor excursions nearly every weekend to instill that same love of the land.

DeLuca has a fondness for books about the land and people pushing their limits — whether physical, emotional or mental. He also enjoys a wide variety of music. However, when it comes to personal accomplishments, he reflects on his own family with gratitude and happiness: “Raising those three boys is probably the best thing I can point to in my life to date.”

It follows that DeLuca places the College of Forestry’s educational mission at the top of his priorities. Kids growing up in urban areas often lack familiarity with rural landscapes, he says, and may associate forestry primarily with clear-cuts.

He notes, however, that in the 1890s, the science of forestry developed in response to the destructive practices of an earlier age. “Forestry was the first environmental science practiced at a landscape level in the United States. We need to reclaim that ground. We need to recapture peoples’ and kids’ imagination around forestry.”

DeLuca believes educational excellence means producing graduates who combine a deep understanding of forest ecosystems with a conservation ethic and strong communication skills.

Toward that end, DeLuca sees his leadership role as enabling faculty and students. “It’s not about me; it’s about us as a college. It’s my job to help create the conditions in which people can do their best work,” he says. “It takes systems thinking and an integration of practice to create an effective team.”

DeLuca recognizes the college has leading institutes and departments, which bring a diversity of perspectives and collaborations to the sustainability challenge. By connecting students with current research, faculty create an exceptional educational experience. Across the state, the OSU Forestry and Natural Resources Extension Program carries the learning to communities that are dealing with issues from wildfire to economic dislocation.

The college has also benefited from the leadership of Anthony S. Davis as interim dean, says DeLuca. “He seized the momentum created by Dean Maness and moved the college forward on multiple fronts, including the completion of the Oregon Forest Science Complex, exploring the creation of the Elliott State Research Forest and the establishment of the Wood Identification and Screening Center at OSU.”

In his research, DeLuca has found the enduring footprint of human activity across the world. For example, in Sweden, where he conducted field work with ecologists and archaeologists, northern forests were regarded as pristine and untouched by humans. However, the Sámi people had managed those forests and alpine tundra for millennia, just as Native peoples exerted a strong influence on forests in North America.

“We have to recognize that humans are part of the landscape,” he says. “They are and always will be.”

Major: Renewable Materials; Year: Senior

Renewable Materials senior Joshua Stump is hungry for international experience.

He landed at Oregon State after earning a Jazz Piano Performance degree from Arizona State University and spending five years in the United States Navy.

“Music was my passion growing up, but my first experience in college was a hard lesson for me about what happens when you don’t take education seriously,” Stump says. “With mounting student debt hanging over my head, I joined the Navy to jump start my life financially.”

After five years, he was ready to move on to the next stage and decided to follow an interest of his since childhood: sustainability and the environment.

“I’ve always had enormous respect for nature and other forms of life,” says Stump, “My dad took me to Mount Rainier National Park as a child, and that made a huge impression on me.”

After researching degrees at Oregon State, Stump chose the renewable materials program, which he knew would lead him toward a career promoting the use of natural solutions for products we use every day, including sustainable building practices.

Stump completed an internship with Boise Cascade during summer 2018. He’s also an apprentice piano restorer.

During his Navy service, Stump traveled to Australia and several Asian countries. He has not visited Europe yet, even though he is extremely interested in the area.

“I have always been very interested in German culture,” Stump says. “I have family heritage there, and I have always been fascinated with their work ethic and interest in art and music. I think Germany would be an amazing place to live.”

He is planning to participate in the short-term, faculty-led Alpine Europe program. The program, offered through the college’s Office of International Programs, takes students to the European Alps and provides a holistic view of the sustainable wood products industry. He is also interested in completing an internship focused on piano restoration in Austria

“I am hoping to combine my interests,” Stump says. “Playing piano has been what has defined me since childhood, and I would love to focus on alternatives for soundboards in pianos. They are made exclusively with Sitka spruce. With Sitka forests disappearing due to climate change, I want to help find alternatives for soundboards.”

Stump says he would love to live in Europe someday.

“My dream is to build a completely self-sustaining home,” Stump says. “I would spend my time repairing and tuning pianos and use my free time to engaging in environmental activism.”

Major: Forest Engineering; Year: Junior

Josh Fix says he’s never seen a photo that accurately portrays just how green the forests in Oregon are.

“They’re almost glowing,” he says. “I love the simplicity of the forest; how quiet and different everything is. They provide a breath of fresh air and create wonder in me.”

Fix, who grew up in Minnesota, first fell in love with the forests of Oregon as a child during a visit to the state.

He initially declared a major in civil engineering at Oregon State before realizing he wanted to work outside.

“I found forest engineering and it was the perfect major for me,” he says. “It allows me to solve the same kind of problems and use applied science, but I get to do it outside where I see a bigger impact because of everything outdoor spaces provide.”

When he’s not studying, Fix works with the College Research Forests as a recreation field assistant. He found the position through the college’s job shadow program. He shadowed Ryan Brown, former Research Forests recreation and engagement program manager, and learned about the open position. Fix, who loves recreation as well as engineering, thought the job sounded like a perfect fit.

“I do trail maintenance, manage invasive species and repair interpretive materials at our trailheads,” Fix says. “There is something different every day.”

Matt McPharlin, recreation field coordinator and volunteer coordinator, is Fix’s supervisor, but Fix says he’s more than that.

“Matt has been a great mentor to me,” Fix says. “He encourages me to think outside the box and get the most out of this work.”

Fix says his favorite part of working in the College Research Forests is interacting with people recreating in the forests.

“I like to stop and say ‘hi,’” he says. “I meet interesting people from the community, many of whom have lived in Corvallis for years and have been using the forests longer than I’ve been alive. I like being able to talk to people and share stories.”

Fix says one of his most impactful experiences on the job was interacting with a group of blind and visually impaired hikers.

“It made me realize how special the College Research Forests are,” he says. “They are able to enjoy the forest in a completely different way than I do. It made me think about how to make the forest more accessible for differently abled individuals.”

When he’s not working, Fix utilizes the forests as a student during labs, but enjoys the forest most when he’s able to enjoy it in his free time.

“When I’m in the forest, I don’t feel the pressure of school,” he says. “I can take a deep breath and dream about my goals to manage and care for a working forest like this one day.”

When the State of Oregon needed to increase revenue for outdoor recreation facilities and maintenance, they turned to Oregon State University for answers to their questions, and for scientific data to help inform their decisions.

A study completed by Randy Rosenberger, professor and College of Forestry Associate Dean for Student Success, connected outdoor activities on trails to health savings by utilizing and recalibrating a tool called the Outdoor Recreation Health Impacts Estimator. The tool was originally developed to focus on transportation decisions (walking, cycling or utilizing public transportation as opposed to driving) to estimate changes in life expectancy and quality of life.

The tool converts positive health effects into monetary unit, and even includes the cost of treating certain diseases as well as the loss of productivity illnesses cause.

The study became part of the 2019-2023 Statewide Comprehensive Outdoor Recreation Plan (SCORP).

“In my research, I quantify things that aren’t normally quantified,” Rosenberger says. “Things like recreation aren’t traded in markets with prices. They don’t have voices. This study gives them a voice, and I think through it, people are starting to realize that recreation is at the nexus of everything. It’s not just something we like to do if we have the time. It’s creating healthier communities and saving those same communities money on health services.”

Rosenberger replicated the study for the McDonald and Dunn Forests, two of the College Research Forests. The college owns more than 15,000 acres of working forests around the state that are utilized for research, outreach and education with some open to the public for recreation. He found that recreation on the Research Forests saved $754,395 in cost of illness savings in 2017 alone. This data can now be used by private and public agencies for planning, budgeting, assessment and grant applications.

By The Numbers

In 2017, the McDonald-Dunn College Research Forests saw 17,271 individual recreation visitors who accounted for more than 155,000 total visits.

McDonald-Dunn Recreation Activity

Walking/Hiking51.5%
Dog Walking19%
Running/jogging16%
Mountain Biking12%
Horseback riding/misc1.5%

Recreation visits to the McDonald and Dunn Forests resulted in $754,395 in cost of illness savings, or health benefits, associated with eight chronic illnesses; and accounted for 14 percent of the total health benefits estimated for all of Benton County ($5.4 million).

Did You Know?

The U.S. Department of Health and Human Services recommends adults get at least 150 minutes per week of moderate-intensity or 75 minutes per week of vigorousintensity aerobic physical activity.

60 percent of adults in Oregon meet this recommendation. 63 percent of adults in Benton County meet this.

The story of Oak Creek: From storage facility to top-notch greenhouse

Visitors to the Oak Creek Greenhouse on Western Boulevard in Corvallis enjoy world-class technology and a variety of seedling studies – plants growing in just about every place one can look. But it wasn’t always like that.

When Assistant Professor Carlos Gonzalez-Benecke arrived at Oregon State in 2015, he toured all of the facilities that were available to him for research projects. One was the Oak Creek Greenhouse, but unfortunately, at the time, it could only facilitate small seedling studies due to the large amounts of timber and nursery materials stored there.

“Once I became oriented with my work here, I made revitalizing the greenhouse a priority,” he says.

Interim Dean Anthony S. Davis and a team of graduate students (Carson Alberg, Matthew Davis, Kaitlin Gerber, Rebecca Sheridan and Christina St. John) shared the vision for a functioning greenhouse that took advantage of all the space and potential the Oak Creek location offered. So, everyone worked together to quickly clean out the space.

Once the space was clear, Gonzalez-Benecke considered what greenhouse characteristics plants like Douglas-fir seedlings need to have to thrive while making the space as flexible as possible for a variety of uses. “Plants need resources to grow: water, nutrients and radiation,” Gonzalez-Benecke says.

Nutrients are easily provided by fertilizers, but Gonzalez-Benecke gave more thought to water and radiation.

“We wanted to be able to manipulate those factors,” he explains. “This is why we installed an extensive irrigation system, as well as fixing the roof that allows us to better adjust environmental conditions inside the greenhouse. We can provide more light or provide a total black out in certain sections of the greenhouse.”

The heating system and fans also manipulate factors including temperature, relative humidity and air movement.

The greenhouse hosts several research projects for the College of Forestry and the College of Agricultural Sciences.

“For our purposes, the greenhouse is perfect,” Gonzalez-Benecke says. “We are proud of it, and we are happy to be a resource for the college and the broader campus community. We invite visitors and members of the industry to come tour it.”

One of Gonzalez-Benecke’s Ph.D. students, Patricio Alzugaray, has a long-term study of Douglas fir seedlings at the greenhouse.

Seedlings can be produced in a wide array of containers, and Alzugaray is testing the benefits and disadvantages of using biodegradable, paper containers. The first phase of the study involved growing the seedlings inside the greenhouse and taking root morphology and physiology measurements.

In October 2019, Alzugaray outplanted the seedlings on five sites across the region. He will continue to monitor their growth and performance.

“It is invigorating to see the quality of research coming out of the Oak Creek Greenhouse, especially considering Oregon State’s historic strength in advancing forest regeneration,” Davis says. “Access to world-class facilities like this help our students and our faculty make discoveries that will sustain healthy forest landscapes in Oregon and beyond.”
