Cristina Eisenberg named a Beaver Research Champion
Cristina Eisenberg, the associate dean for inclusive excellence and Maybelle Clark Macdonald director of Tribal initiatives in natural resources, was named an Oregon State Beaver Research Champion. Eisenberg leads the Indigenous Natural Resource Office, and within it, the Traditional Ecological Knowledge Lab. In partnership with five Sovereign Tribes in Oregon, her team is weaving together Indigenous Knowledge with western science to help the Bureau of Land Management adapt its forests in Oregon to be more resilient to climate change. Eisenberg and Dean Tom DeLuca recently received a $1M grant to work with leaders from the U.S. Forest Service and Tribal Nations to convene a series of Tribal roundtables around the Pacific Northwest. This work is in direct response to President Biden’s Executive Order 14072, which calls for conserving and safeguarding mature and old-growth forests.

Pacific Northwest’s semiconductor and sustainable timber industries to be strengthened by two tech hubs
The White House, through the U.S. Department of Commerce’s Economic Development Administration, announced the designation of 31 Tech Hubs. Oregon State is the only university to lead two. The Pacific Northwest Mass Timber Tech Hub, led by TallWood Design Institute, a collaboration between Oregon State’s College of Forestry, College of Engineering and the University of Oregon, aims to be a global leader in mass timber design and manufacturing manufacturing, with a goal of reducing the construction industry’s carbon footprint and improving housing affordability.

Revision of Pacific Northwest bee ID key to support identification of native pollinators
Associate Professor Jim Rivers, in collaboration with OSU Extension, Oregon Department of Agriculture and Mt. Pisgah Arboretum, developed several bee ID keys to support native bee identification in the Pacific Northwest. The last version of the bee key was published in 1969. Given the growing interest in native pollinator conservation, the new bee ID keys will have a strong impact on bee research in the region.

Forest modeling shows which harvest rotations lead to maximum carbon sequestration
Forest modeling completed on the McDonald-Dunn Research Forest by College of Forestry graduate
student Catherine Carlisle and professors Temesgen Hailemariam and Stephen Fitzgerald, shows that a site’s productivity — an indicator of how fast trees grow and how much biomass they accumulate — is the main factor that determines which time period between timber harvests allows for maximum above-ground carbon sequestration. Over a 240- year projection timeframe, scientists found that for highly productive stands, 60-year rotations with low-intensity thinning at 40 years led to the greatest carbon storage (in the standing trees plus what was removed from the thinning). For stands on less productive sites, they found carbon storage was maximized by rotation periods of 80 years or 120 years.

Update from the H.J. Andrews Experimental Forest
On August 5, 2023, a lightning strike ignited a wildfire within the H.J. Andrews Experimental Forest and Long-term Ecological Research site in Oregon’s Cascade mountains, ultimately burning across 70% of the forest. The fire, dubbed the Lookout Fire because the ignition point was on Lookout Mountain, burned 25,000 acres, incinerating long-term, decades-old research plots and altering study sites.

2023 also marked 75 years of ecological data collection, and 42 years of Long-term Ecological Research (LTER) inquiry. The Andrews, as it’s affectionately known, also celebrated a successful midterm review by the National Science Foundation.

Throughout the challenges and celebrations, the H.J. Andrews community continues to make discoveries about the forest and engage with forest managers, teachers, students of all levels, artists, writers, musicians and many other groups.

Bridging gaps between forestry and engineering to better understand community resilience to wildfire
Wildfire researchers from Oregon State University, including College of Forestry Assistant Professor Chris Dunn, have received $750,000 for multiple projects to advance the science of wildfire risk and resilience. The strategies include embedding a doctoral student in Ashland, Oregon, the site of the largest primarily urban blaze in Oregon history that occurred in 2020; planning a global center for transdisciplinary wildfire research on community resilience; and creating a wildfire risk and resilience graduate program jointly advised by faculty in OSU’s colleges of engineering and forestry.

Researchers from 6 countries are coming together to advance mass timber adoption

Approaching research with an international lens enables Oregon State University to enter a global dialogue — and take steps towards changing the world. One example? The Converging Design project, a powerful international mass timber research collaboration spearheaded jointly by a team from Oregon State, Colorado State University, Stanford and Penn State University.

Funded by the National Science Foundation, the USDA Agricultural Research Service and private industry, the project’s aim is to investigate the seismic resilience of mass timber and its strength as a low-carbon structural building material. This is important, as this data is critically needed to help speed along the development and adoption of building codes, showcase the sustainability of the material and increase the manufacturing of modular and prefabricated mass timber structures that will result in widespread U.S. adoption, as seen in other countries around the world.

To gather the necessary test data, the research team is conducting a shake-table test on a six-story mass timber building at the national shake-table testing site at the University of California San Diego. Part of the Natural Hazards Engineering Research Infrastructure, the shake-table is the largest in the world.

Originally 10 stories tall, the test building was constructed by the Colorado School of Mines, with the support of international partners including the University College London in the U.K, University of Canterbury in New Zealand, University of Kyoto in Japan, and University of Camerino in Italy. To gather the seismic data needed for this project,the structure only needed to be six stories, so prior to the testing, the OSU teams deconstructed the top four stories of the building. The salvaged components are being repurposed into refugee housing in Tijuana, Mexico, showcasing the potential for mass timber reuse.“It’s exciting to work with such a diverse group of both academic and industry partners,’’ said Andre Barbosa, the Glenn Willis Holcomb professor in structural engineering at the College of Engineering. “This unique project is one of the first demonstrations of mass timber reuse and of mass timber’s seismic resilience.”

Barbosa, in collaboration with Arijit Sinha, professor of wood science and engineering and JELD-WEN chair in wood-based composites science at the College of Forestry, originally started investigating the systems using a three-story mass timber structure. The test structure was built inside the Oregon State University A.A. “Red” Emmerson Advanced Wood Products Laboratory lab at the TallWood Design Institute. This allowed the team to investigate initial design methods, assumptions and obtain results before refining them for the larger six story building seismic testing at UC San Diego.

“This work is vitally important to validate the use of mass timber and other technologies as vehicles to make buildings safer and more resistant to earthquake activity while simultaneously storing carbon,” Sinha said. “This creates a synergistic combination for enhanced structural and environmental performance.”

The test structure will undergo a three-phase test process (see below), employing different seismic lateral force-resisting systems in each test. These systems employ a variety of vertical elements in the construction of buildings to help transfer lateral loads like heavy winds or earthquake ground motion shaking. They also allow a building to rock, sway and dissipate the energy, and self-center after shaking, therefore minimizing damage.

The project tests different resilient lateral force resisting systems (LFRS) over three phases to advance seismic resiliency. Phase 1 involves testing post-tensioned rocking wall systems (both cross-laminated timber [CLT] and mass plywood panels [MPP]) similar in nature to the LFRS used in the College of Forestry’s Peavy Forest Science Center. This system uses steel U-shaped flexural plates for energy dissipation and tensioned rods for self-centering action. Phase 2 features post-tensioned MPP shear walls reinforced with buckling-restrained braces (BRBs), which are placed at the bottom of the walls instead of along their entire length, such as with U-shaped flexural plates. Phase 3 will explore a hybrid wood-steel system, replacing the mass timber shear walls with a resilient steel moment/braced frame hybrid system, but keeping mass timber floors.

In November 2023, the Converging Design team completed Phase 1. They found the mass timber structure experienced virtually no damage after nearly fifty ground motion shakes from the shake-table, demonstrating the resilience of the building system. Phase 2, completed in January 2024, showcased the resilient nature of the post-tensioned mass timber walls with buckling-restrained braces. The remaining phase of testing is expected to be complete by spring 2024. Follow along and find live updates on the TallWood Design Institute website!

Tell us about your background – what drew you to your specialty area?
My fascination and deep interest in wood as a building material originated during my time as an architecture student in Florence. One of my deepest passions lays in cultural heritage preservation. Most of the projects we were exposed to at school were predominantly centered around masonry buildings. So, the prevailing perception was that our cultural heritage predominantly consisted of stone and bricks. In 1997, a powerful earthquake struck Umbria, a central region in Italy, resulting in the loss of invaluable monuments. During site inspections, a clear observation emerged: many damages to masonry buildings and vaulted structures resulted from interventions carried out in the previous decades. These interventions involved the replacement or supposed reinforcement of original timber roofs with reinforced concrete. The underlying cause of these misguided practices and the prevalent mistrust in wood as a building material became evident – a long-standing educational system that disregarded the importance of traditional materials and exclusively trained designers in the use of modern materials. For my master’s thesis, I began examining a specific traditional timber system: timber vaults. The ingenuity of this technique lies in its light weight and flexibility, that reduces the risk of damage to masonry walls in the event of an earthquake. After graduation, I engaged in the restoration of some of these structures. My interest in pursuing a PhD in the Timber Engineering Group at the University of Trento stemmed from this experience and my objective to enhance diagnostic procedures to avoid invasive interventions on timber cultural heritage.

What courses do you teach / labs do you lead?
WSE 225 “Building design innovation with wood” introduces students to the fundamentals of building design and the relevant technical requirements, the solutions available and the specific applications, with a focus on wood-based products and other ligno-cellulosic materials. The main goal of this course is to help students develop a multi-disciplinary understanding of design and construction principles that facilitate communication between manufacturers, architects, engineers, and clients.

WSE 425/525 “Timber tectonics in the digital age” is an interdisciplinary, inter-institutional effort in collaboration with University of Oregon Architecture enrolls Architecture, Engineering and Wood Science students. The course is designed to prepare future professionals for integrated design practices in modern wood construction, emphasizing experiential learning and soft skill development. In this course, students engage in hands-on project, engaging with real clients and industry partners throughout the learning process.

The faculty-led study abroad program that I lead, Tradition and Innovation in the Wood Construction Industry: A Journey in the Italian Alps, provides an international perspective on tradition and innovation of forest products application and sustainable practices in the built environment. I’ve designed this program to offer students firsthand experience in the working environments and practices of the host country through job-shadowing opportunities with local companies, encouraging them to reflect on practices in their home countries. In the next iteration of the course, I plan to collaborate with local stakeholders in the US to connect students’ international experiences with tasks related to a real project back home.

Another chance to immerse students in both tradition and innovation within the sector, involving them in a tangible project and providing them opportunities for community engagement, is the course on “Structural Health Assessment and Monitoring of Timber Structures“ that I offer to graduate students. During the class offered last spring, for instance, students actively participated in assessing timber trusses at the Arauco facility in Albany. They offered valuable feedback to the client regarding the structure’s conditions and they identified causes of damage. Additionally, the students had a chance to talk about their project during the historical preservation month.

I teach and co-developed WSE 540 Introduction to Wood Science and Engineering. This is the first hybrid introductory course of the new WSE Graduate Core.

Tell us about a recent/current research project you are working on
With the two wood innovation grants received with my colleague Lech Muszynski, our objective was to leverage underutilized wood species to create CLT panels for an untapped market segment: modular deployable units. These units can serve as temporary and transitional solutions, such as post-disaster scenarios, and are designed to be disassembled and reused in other contexts. This exploration aims to optimize resources during the production stage, extend the service life of applications that are typically short-lived, and reintegrate resources into the loop. It aims to support the resilience of the natural and built environments, promote sustainability in forest management, and foster economic development within communities. Since its initiation in 2017, this research stream has garnered significant attention from both academia and industry. As mass timber products represent just one facet of an integrated approach to create a more resilient and sustainable ecosystem, I am currently working on expanding and enhancing our portfolio of alternative wood-based products and construction systems. This involves exploring alternative ligno-cellulosic sources and a dedicated focus on context-sensitive approaches for material and construction method selection. For example, when addressing shelter and housing needs, I am working on developing partnerships with affected communities to develop culturally appropriate solutions that make the most of locally available resources.

What are today’s students most eager to learn?
Students are passionate about learning how to contribute to solutions for a more sustainable future. They thrive on engaging in projects that offer tangible results and address real-world issues.

What’s the one thing you wish people knew about the Wood Science degree program?
One aspect I’d like people to know about the Wood Science degree program is that it’s a rewarding environment for individuals passionate about sustainability, innovation, and global impact.

Weyerhaeuser and John Deere are partnering to supply the College of Forestry’s Mechanized Harvesting Laboratory with four new harvesting simulators that will engage students, teach machine operation skills, and provide experiential learning activities in forestry. The laboratory is directed by Kevin Lyons, the Wes Lematta Professor in Forest Engineering, and now has 22 harvesting machine simulators with nine available for our high school loan program. The new John Deere forest harvesting simulator systems will permit OSU to expand the high school loan program, which provides career and technology education in high schools.

The mission of the Mechanized Harvesting Laboratory is to increase the knowledge of modern mechanized harvesting systems. Students in forest engineering labs run simulations and explore how to reduce environmental impacts due to harvesting forest products. By bringing these simulators into high school classrooms, high school students can get a taste for how advanced forestry tools allow for efficient timber harvesting and support environmental stewardship.

The state-of-the-art John Deere forest harvesting simulator system includes a terrain editor where users can easily build terrains based on map data or their own imagination. The harvesting machine simulator is designed for training operators, and provides experiential learning opportunities for machine operation and management. Students are able to compare potential forest treatment options gaining a deeper understanding of the links between the environment, machine and treatment prescriptions.

Participating high schools are provided with a forest harvesting machine simulator to use in their classroom. Currently the Mechanized Harvesting Lab is partnering with Yoncola, Oak Ridge, Sweet Home, Tillamook, and Nia-Kah-Nie high schools. Schools value having the OSU College of Forestry provide simulator equipment, workshops at their schools run by OSU faculty and students, and access to the Peavy Forest Science Center and the Mechanized Harvesting Lab for class field trips. This gift from the Weyerhaeuser Giving Fund and John Deere will help expand the number of schools the lab is able to partner with.

Despite being one of the first landscape level conservation practices in the U.S., forestry is often unfairly characterized as an extractive, land degrading practice by some modern conservation special interest groups. However, forestry is a renewable industry and well managed forest lands have broad conservation value, argue Tom DeLuca and Jeff Hatten of the College of Forestry in a recent article published in the journal Anthropocene. The authors use forestry, which is conducted on regenerated forests and involves timber harvest, tree planting, and forest stand maintenance, as a case study for conservation.

Using a soils-based assessment of different land-use practices, they show that forestry incentivizing land management practices that cause minimal soil disturbance could help advance our nation’s ability to achieve large scale conservation objectives such as 30% of land area conservation by 2030.

Soil, not above-ground vegetation, represents the largest terrestrial body of stored carbon on Earth and a wellspring of biodiversity, and should be at the center of conservation efforts. Land use practices that maximize continual live vegetative cover, minimize bare soil, and maximize native species composition are more likely to protect soil and store a greater amount of carbon.

Adopting or incentivizing land use practices geared toward conservation will allow the United States to meet its goals, while simultaneously providing the population with wood and other forest products necessary for providing climate smart, affordable housing or shelter, and supporting critical ecosystem services including recreation and access to nature. Sustainably using managed forests in the U.S. for our resource needs, rather than relying on countries with lax environmental standards, can help with global conservation goals.

PROJECT
Water quality and availability are critical parts of life – for humans, ecosystems and every species on Earth.

Forested watersheds are an important part of this equation as they provide water, sediment, and nutrients that shape the health of aquatic ecosystems. Forested watersheds also make up a large portion of the landscape in places like the Pacific Northwest. And how water moves through forested watersheds impacts the supply of clear water – along with things like the quality of fish habitat and the well-being of hydraulic infrastructure, like culverts.

Many external factors can affect hydrologic processes including drought, wildfire, timber harvests, and urbanization. Therefore, understanding how forest management decisions, human activity, and natural disturbances influence the flow and supply of water is fundamental to sustainable management. Forested mountainous ecosystems are especially challenging because they see a complex array of physiography and the records of water data are usually sparse.

This project, led by Oregon State University Associate Professor Catalina Segura, is aiming to build knowledge about the vital process of water movement in forested watersheds – by researching how storm events affect water and sediment transport through forested watersheds.

IMPACT
This research will help inform management policies, practices, and regulations in forested watersheds by offering critical insights into hydrologic processes. It will provide valuable data and tools to better understand and predict the impacts of disturbances to forested watersheds.

COLLABORATION
Researchers and students from Oregon State University’s College of Forestry are partnering with researchers from the Environmental Protection Agency (EPA) and the U.S. Forest Service Pacific Northwest Research Station to conduct this work.

PROJECT
Having a reliable way to monitor and analyze forest inventory is a key part of managing forests and forecasting forest dynamics. Remote sensing techniques offer a way to do this vital work, as they allow forest managers to consistently collect a large amount of relevant data and information across vast landscapes. This data provides valuable insights into the status and trends of forests, which supports informed decision-making related to forest management.

The most common remote sensing method used to collect data about tree dimensions and defects, has been laser scanning, or lidar (light detection and ranging). Lidar has traditionally been used to observe the forest from above the canopy and take vertical measurements of tree dimensions, but it is less reliable for producing horizontal measurements. Lidar is often supplemented by field measurements, which provide on-the-ground observations to round out the data.

In the last decade, with improvements in laser technology and decreased use costs, it’s now possible to scan the forest from below the canopy, usually using handheld mobile lidar systems. While this technology collects robust data from below the canopy, it does not provide information about the tops of the trees, as the above-the-canopy lidar system does.

This means that to compile a comprehensive forest inventory, multiple datasets are needed. However, it can be challenging to combine datasets because georeferencing technology that efficiently merges datasets is lacking.

This research project, led by Oregon State University Associate Professor Bogdan Strimbu, aims to improve forest inventory data collection by developing an operational system to integrate the data, or point clouds, and provide a more complete inventory of forests.

The goal is to develop two software programs, one that will fuse point clouds from above and below the canopy – and another, which will compile a comprehensive forest inventory from point clouds.

IMPACT
The researchers hope that this project will improve forest monitoring and analysis and hep inform decision makers. Comprehensive 3-D datasets can provide information about threats to trees including fire, insect, diseases, and competition. A near complete picture of the forest ecosystem will help researchers and forest managers better understand the effects of climate change, the state of wildlife habitat, and the status of carbon storage in forests. Quickly produced and reliable data can help decision-makers implement more sustainable forest management practices.

PROJECT
Mass timber building technology offers an opportunity to utilize more sustainable materials in construction because mass timber can serve as a carbon sink and lock carbon away in the building structure, instead of consuming more energy, like materials such as steel and concrete. Mass timber materials are also usually manufactured from domestically grown products, instead of sourced from foreign countries, which can provide additional energy savings and support local economies.

But while there are many potential benefits to using mass timber, mass timber structures in the United States face a major challenge from termites and fungi, which can cause damage to the wood and lead to early failure of a building. While standard wood frame buildings can be protected from termites through different preservative treatments, the chemicals used in these treatments can interfere with the resins that hold mass timber panels together, and make the panels unusable in building applications. Mass timber panels also rely on moisture barriers to increase the durability of the materials, and termites can attack the dry wood behind these barriers.

To successfully expand mass timber construction in the United States, a solution to the termite problem needs to be identified. If mass timber construction fails due to decay, it could hurt public confidence in this green technology and threaten its long-term potential. The project, led by Oregon State University Assistant Professor of Wood Science and Engineering Gerald Presley and graduate student Cody Wainscott, aims to test different treatments for cross-laminated timber panels (CLT), to identify a treatment that would maintain mass timber’s structural integrity and improve the durability of the material against termites and fungi.

Presley’s lab has manufactured experimental materials to test different treatments on Douglas-fir lumber to identify a treatment with the most potential.

IMPACT
Oregon State University researchers will provide valuable information about the most effective treatments for CLT panels. Their research will help guide mass timber manufacturing practices to produce more durable and reliable wooden structures, that are better protected from decay and termite attack. This could position mass timber materials to be more widely used as an environmentally-friendly and sustainable building material across the globe.

PROJECT
A common assertion made about forest policy is that policies are shaped by science. Oregon State University Professor Michael Paul Nelson is examining how accurate that belief is – and investigating how values factor into forestry policy decision-making. To do this, Nelson will analyze the soundness of the arguments that shaped different forest policies and the values that informed those arguments.

People often seek evidence or information to guide them toward good outcomes when making decisions. However, preconceptions can influence the way that people see the world. These preconceptions can influence what information people seek and how people use the information available to them. Nelson will explore preconceptions and how people filter information and blend scientific facts, and the impact of long-term versus short-term data in that filtering.

In addition to understanding how science and values influence decision-making, Nelson will specifically examine how people conceptualize and understand mature and old-growth forests. To do this, he is using a “mental models” approach. Mental models are a framework from cognitive psychology for understanding how individuals arrange and relate their beliefs, knowledge, and experience on a specific topic ( Jones et al., 2011).

Understanding how decision-makers conceptualize and understand the scientific information presented will help advance our understanding of how values and science interact to inform forest policy.

IMPACT
This research project will explore how science and values interact and influence natural resource or forest management decisions as well as how people filter and blend scientific information to understand and conceptualize topics.

COLLABORATION
Oregon State University will collaborate with many partners while conducing this research, including the National Science Foundation Long Term Ecological Research program, the H.J. Andrews Experimental Forest, the United States Geological Survey, National Ecological Observatory Network, Oregon Climate Change Research Institute, and the United States Forest Service, including the Pacific Northwest Research Station and the Willamette National Forest.

PROJECT
Marbled murrelets can serve as an important indicator species for both healthy forests and healthy marine environments, as this small seabird gets its food sources from marine waters but commutes many miles inland to late-successional and old-growth forests to breed.

Murrelets are found along the coasts from Alaska to Central California. Their population has declined significantly from historic levels and they are now listed as a “threatened” species under the federal Endangered Species Act in California, Oregon and Washington. The reasons for their decline are due largely to the loss of older forests needed for breeding, and much remains unknown about this bird and the factors that influence populations. This knowledge gap has made it difficult to develop best practices for protecting murrelet nesting habitat, particularly around how different management activities will affect the marbled murrelet and its habitat within working forest landscapes.

The knowledge gap has been further challenged by the cryptic breeding behavior of the murrelet, which is difficult for researchers to track and observe.

Oregon State University Assistant Professor Jim Rivers is leading a research project to build knowledge about marbled murrelets, so conservationists and forest managers can better understand the factors that limit reproduction in coastal forests. This research will provide more certainty about how murrelet breeding ecology is influenced by factors such as ocean warming and timber harvest practices within actively managed forest landscapes. This information could help forest managers implement measures to conserve murrelet populations, while also practicing active forest management that allows for timber production.

The team of researchers has been conducting field investigations to collect data and observations about the murrelets’ breeding behavior, habitat and nesting needs, and the greatest threats to their reproductive success.

IMPACT
This research will provide foundational knowledge about the marbled murrelet population and its habitat needs in its listed range. In turn, this will help inform forest management and conservation decisions to better protect this threatened species – while also allowing for timber harvests and other forest management activities in Oregon. This research will also offer insights into how to enhance ecosystem health across landscapes, including forest and marine biodiversity.

COLLABORATION
Oregon State University is partnering with many other groups on this project, including the USDA Forest Service, the Bureau of Land Management, the Oregon Department of Forestry, The National Council for Air and Stream Improvement, the forest industry, and the environmental community.
