For Skye Greenler, a fire ecologist and PhD candidate, fire management has been part of her life from a very young age.

“I grew up on a family farm in Wisconsin that was half organic cropland and half restored tall-grass prairie,” says Greenler. “Conducting prescribed prairie burns was a celebration of the changing seasons, and balancing production with sustainability and conservation was an integral part of working on the land.”

Her family’s prairie management emulated that of upper Midwest and great plains tribes, which instilled a deep interest in the practices of Indigenous fire managers. The farm also taught Greenler to think critically about sustainably using the land, building healthy ecosystems to buffer resources through bad years, and balancing a range of seemingly contradictory objectives— the questions she’s still thinking about today.

Greenler is at the forefront of a more holistic perspective in scientific inquiry. She is working to understand how systemically entrenched bureaucracy, patriarchal mindsets of command and control and injustices to underrepresented communities inhibit adaptation to our current fire challenge.

She arrived at OSU excited about the opportunity to study wildfires in one of the most fire-prone landscapes in the nation, where science, management and policy decisions often drive changes in the region and across the country.

Her dissertation focuses on identifying when wildfires can help restore historical and healthy forest conditions in eastern Oregon and northern California. A major part of her dissertation focuses on developing landscape-scale fire models for northern California that incorporate Indigenous fire management practices into cutting-edge fire modeling and management tools.

“This work is a collaboration with Karuk tribal experts, resource managers and scientists. Working together, we will better understand historical forest conditions, implications of different management decisions, and the changes necessary to build future climate and wildfire resilient ecosystems and communities,” says Greenler.

Greenler says there is an urgent need to reassess how we manage and live with fire in Oregon and many places across the globe.

“Understanding when, where, and how fire is beneficial on landscapes is critical for us to work towards promoting good fire and coexisting with fire rather than needing to fight and fear all fire,” says Greenler.

There is also increasing recognition of the importance of Indigenous fire management in restoring landscape resilience, reducing risk to communities and promoting critical first foods and medicines.

“This work is very place-based and needs to be led by local tribes, not Western scientists, but I see a lot of hope in collaborative work that centers Indigenous fire stewardship and land management,” says Greenler.

Greenler hopes that fire scientists can transition to uplifting Indigenous fire management in the following decade and collaboratively create a tangible and substantial space for cultural burning within fire management and landscape restoration.

“In the western United States, wildfire is a natural process that is foundational to maintaining ecosystem health but is increasingly a destructive event that can result in loss of life, property, and valued natural resources,” says Greenler. “Science, management, and policy that together can reduce the risk of uncharacteristic, destructive fires, while promoting natural fire and forest processes is critical to restore forest resilience and reduce risk.”

Greenler’s major professor John Bailey, professor of silviculture and fire management, says she exemplifies the combination of intellectual ability, talent, drive and heart to advance the College of Forestry’s mission for research, teaching and outreach.

After receiving a Provost Fellowship, Greenler helped found the Traditional Ecological Knowledge Club, which supports Tribal rights and inclusion in natural resource stewardship, including hosting a recurring conference on Traditional Ecological Knowledge in ecosystem sustainability. She served as the President of the Student Association for Fire Ecology and is one of 100 doctoral students in the U.S. and Canada selected to receive the Scholar Award from the P.E.O. Sisterhood.

Greenler received a master of science degree from Purdue University in 2018 and a bachelor of arts degree in ecology from Colorado College in 2014.

Oregon State University assistant professor of global change conservation Takuya Iwamura wants to address the pressing matters of biodiversity conservation and a sustainable future through his research.

“International agreements such as the United Nations Sustainable Development Goals have brought global attention to the importance of ecological integrity for our survival. I believe our research can contribute to turning the tide to increase the chance of a better existence in the future under global change,” Iwamura says.

To address the sustainability issues arising from human and nature interactions, he applies a holistic approach based on quantitative methods such as remote sensing, GIS and computational modeling to forest, animal and human activities.

Iwamura thinks this mixed approach is more appealing to a broader audience who is not necessarily interested in traditional scientific communication such as mathematical formulas.

“Computational modeling and simulation is a more accessible format to tell a strong and moving story about science and research,” Iwamura says. “Many people want to know about biodiversity extinction and human health risks, and when you see a human character moving in an actual landscape and encountering, for example, snakes in the field in our model, it captures your imagination.”

One example of Iwamura’s work is building a spatially explicit human-snake interaction model to explain snakebite risk in Sri Lanka.

He and his team applied mixed research methods based on remote sensing, snake observation, and social interviews related to farmer behaviors. They combined this information using agent-based modeling (ABM), a bottom-up computational simulation approach to model human agents in a realistic landscape.

“We created a computational unit to represent a farmer’s behavior and see how they move across a virtual landscape,” says Iwamura. “We then estimated snakebite occurrences based on potential snake distribution and overlap with humans, which is temperature and precipitation sensitive.”

Iwamura and his team discovered that the type of farming a farmer does, whether rice, rubber or tea, significantly affects the risks associated with snakebites.

As farmers choose different farming methods to adapt to a changing climate and snakes also shift spatially and temporally to adapt to climate change scenarios, snakebite risk adjusts.

“Revealing the mechanism of human and nature interactions is the key to many pressing problems that our planet faces,” says Iwamura. “I believe our approach will be useful to understand how society and ecology adapt to recent global changes, including climatic and land-use changes.”

As a faculty member in the forest, ecosystems and society department, Iwamura researches ways for human beings and nature to coexist. After studying complex systems and artificial intelligence, he worked as a business consultant in Tokyo to learn problem-solving with the hope of applying tools for business management to solve environmental issues.

He moved to the United States to study environmental management at Duke University. He discovered his interest in biodiversity conservation, working first as an intern at World Wildlife Fund (WWF) in Washington, D.C. He was intrigued by academics and research, which led him to Australia to pursue his PhD in spatial resource allocation with Professor Hugh Possingham, who later served as chief scientist at the Nature Conservancy.

“Working with Hugh taught me a lot, especially about impactful science for environmental problem solving,” says Iwamura.

After his time in Australia, Iwamura moved back to the U.S. for a postdoctoral position at Stanford University. He studied geography with Professor Eric Lambin and gained experience working with and researching Indigenous communities with Dr. José Fragoso.

“This was a perfect transition, and it broadened my horizon quite a bit into the human side of things,” says Iwamura.

Iwamura then moved to Israel to be an assistant professor at Tel Aviv University. All those moves forced Iwamura to do the hard work of learning a different language and culture, shaping him into a global citizen adept at navigating human and social dimensions and viewing experiences and life through multiple lenses.

Iwamura believes an interdisciplinary approach is the key for solving ecological problems. He is interested in revealing the mechanism to explain how nature and humans interact using the scientific domain of social-ecological systems.

Iwamura joined the OSU College of Forestry in January 2021 and looks forward to an in-person fall resumption and working with many people across campus.

“I am particularly excited with the collaborative nature of OSU. I have already started some work at the H.J. Andrews Experimental Forest, where I met many researchers and friends. It feels good to know we have such a strong community,” says Iwamura.

Trevor Denning, class of 2022, uses a wheelchair and loves the outdoors. But sometimes, those two worlds aren’t compatible. He wants to change that.

Denning is on a mission to make the outdoors more accessible to those with physical disabilities. He was inspired to pursue this goal after visiting Grand Teton National Park and realizing he wasn’t able to do as much as non-disabled people.

“The greatest barrier or obstacle to accessibility is the lack of knowledge about the vast amounts of disabilities that exist,” says Denning. “It is not a one shoe fits all type of problem to address.”

Most of the time, he says, the people making decisions about accessibility issues are not disabled and have no firsthand knowledge on how to make a state, local or national park accessible.

“I believe that there need to be more people that are disabled in these positions because they are the ones with the real-world experience and know what needs to change,” says Denning. “On many occasions, I have visited an area that is deemed ‘accessible,’ and in fact, it is not.”

Originally from Florence, Oregon, Denning is pursuing his bachelor’s degree in tourism, recreation and adventure leadership with a double minor in natural resources and leadership. Denning chose OSU because of the TRAL major, and also because of the welcoming community and college town feel of Corvallis.

“One of the best things about OSU is meeting so many students on campus that come from diverse backgrounds such as international students, military and veteran personnel, folks with the same passion I have for the outdoors and plenty of students with disabilities,” says Denning. “OSU is very welcoming to all students.”

When not in class, Denning likes to explore the outdoors with his partner, something he’s able to do on his ReActive Adaptations custom off-road handcycle.

The handcycle was custom-built for Denning and funded by a local community fundraising effort, including donations and grants. The handcycle includes an electric assist that can support Denning as he explores areas previously inaccessible.

“My favorite part about having my ReActive Adaptations off-road handcycle is the fact that I can do so much more by myself now,” says Denning. “When I want to explore a new area, I do not need someone there to push me in my daily wheelchair because I can now transfer into my handcycle and ride until I want to stop and go over, down and around terrain that I am not able to with my wheelchair.”

Denning still gets emotional when he rides his handcycle, which he received in 2019. He’s been in a wheelchair since he suffered a spinal injury in 2011 when he was just 15 years old. For nearly ten years, he could not do the things he loved, like being outdoors and accessing the backcountry.

“Now I can, and that is such a freeing experience,” says Denning. “It’s one thing not to get outside and explore. It’s a whole other thing when it is taken away from you, and you cannot do those simple activities that a lot of people take for granted.”

In addition to loving the land, Denning also loves the skies. He’s a licensed pilot and tries to fly planes as often as possible.

He grew up flying on the weekends with his pilot grandfather. They would fly to small airports around Eastern Washington, eating breakfast at the diners located across the street. After Denning’s accident, his grandfather showed Denning an article from his Aircraft Owners and Pilots Association (AOPA) magazine about the Able Flight program. Able Flight’s mission is to offer people with disabilities a unique way to challenge themselves through flight and aviation career training, and by doing so, to gain greater self-confidence and self-reliance.

“Seeing pictures of students learning to fly that looked like me and using a wheelchair was very inspiring, so I applied,” says Denning. “On Christmas day in 2015, I was contacted by the program director to inform me that I was accepted to the class of 2016 Able Flight students at Purdue University.”

Denning says he is proud having the title of “pilot” and it is one of his greatest achievements.

After graduation, Denning hopes to work for a federal agency such as the United States Forest Service, Bureau of Land Management, National Park Service or the Army Corps of Engineers to help make outdoor areas more accessible to people with physical disabilities.

“Navigating a non-disabled world is tough,” says Denning. “Restaurants, grocery stores, bookstores, classrooms, and housing are some of the many things that need to be fixed and made more accessible. The first step is having people that are disabled in a position to make these changes. I want to be one of those people.”

The Oregon State University College of Forestry welcomes Professor Holly Ober as the Associate Dean for Science Outreach and Program Leader for Forestry and Natural Resources Extension

“I am thrilled to join the OSU College of Forestry,” says Dr. Ober. “The breadth and depth of the expertise of individuals involved in Extension and Outreach within the college are impressive. The Forestry and Natural Resources Extension program at OSU is one of the largest and most comprehensive natural resource Extension programs in the country, and widely recognized as one of the best.”

Previously Dr. Holly Ober served as Associate Program Leader for Natural Resources for the University of Florida Cooperative Extension Service. In the role, she provided leadership for approximately 150 county and state faculty. Dr. Ober was also a Professor and Extension Specialist, conducting applied, interdisciplinary research to increase understanding of the mechanisms that influence wildlife habitat selection and productivity in forests to inform conservation and management strategies. She raised over $2.2 million in external funding and nearly $300,000 in internal funding, advised 11 graduate students, three undergraduate interns, and two post-doctoral researchers during her career. She has authored 42 peer-reviewed articles in wildlife, forestry, and inter-disciplinary journals.

As an Extension Specialist, she taught agency employees and private landowners to sustainably manage natural areas and improve stewardship of forests to provide habitat for wildlife. She led multi-day Extension workshops for natural resource managers, gave presentations to Extension audiences, produced peer-reviewed Extension documents to serve as a resource, and wrote several journal articles on the scholarship and importance of Extension.

Dr. Ober received her PhD from Oregon State University in Forest Science and Wildlife Biology in 2008. 

“Dr. Ober brings a great deal of experience, knowledge, and energy to this position,” says Tom DeLuca, Cheryl Ramberg-Ford and Allyn C. Ford Dean of the College of Forestry. “We were fortunate to attract her back to OSU from her position at Florida.”

Ober believes the need to convey information about the management of Oregon’s forests and the production of forest products has never been greater as we collectively grapple with complex issues.

“Just as teaching is essential to training the next generation of scientists, and research is essential to generating better understanding, Extension and outreach are essential to ensuring that scientific knowledge gets into the hands of people who need it to make sound decisions outside the formal university setting,” Ober says.

A group of scientists and forest managers at OSU and the US Forest Service are asking community members who experienced the June 2021 Pacific Northwest heat wave event to participate in foliage scorch research. Community members are invited to observe the heat impacts to foliage and report their observations using a website created by the Oregon Department of Forestry to survey drought impacts on forests.

Following two years of drought, many areas of the Pacific Northwest and British Columbia experienced unprecedented air temperatures during an extreme heat wave in late June and early July of 2021. 

This event led to numerous reports of foliage scorch and leaf drop in westside forests of the Oregon coast range and the Cascades mountain range. Western hemlock (Tsuga heterophylla) and Western Red Cedar (Thuja plicata) seem to have been the most impacted tree species, but Douglas fir (Pseudotsuga menziesii) and various alder and maple species were also affected. Notably, trees and saplings with direct solar exposure and on south-facing slopes seemed to suffer the worst foliage scorch. 

Researchers do not know what the near- and long-term physiological causes and consequences of foliage scorch and heat stress will be, at either leaf or tree scales. The impacts could range from impaired metabolism on surviving leaves to reduced stem diameter growth to eventual tree mortality. This event provides a unique opportunity to probe the physiological and ecological responses to an extreme heat wave in important tree species of the Pacific Northwest.

Researchers ask that anyone participating in the research please note in the “Description and/or caption information” of the survey that participants are reporting ‘impacts of the June 2021 heat wave‘ and also use the phrase ‘foliage scorch‘ so researchers can retrieve these observations later for mapping and analysis of this extreme event.

Bingo VRRH harvest post-operation. Photo shows clumps of trees that are retained throughout the unit.

The OSU Research Forests recently performed two variable retention regeneration harvests (VRRH). Yes, it is a mouthful! Can you say it five times fast?

A VRRH is a harvesting technique that seeks to retain varying densities of trees throughout the harvest unit. Foresters implement VRRH for a variety of reasons including providing more wildlife habitat, enhancing visual aesthetics, and retaining forest structural elements that are associated with structurally complex stands.

We completed a VRRH harvest in 2020, and ‘Bingo’ VRRH was its name-o. We chose the 68-year-old mature stand as part of an experiment because VRRH’s had not been widely performed in the Research Forests in the past. The Bingo unit contained predominately even-aged Douglas-fir with a small component of grand fir and hardwoods (e.g., bigleaf maple and Oregon white oak). The pre-existing trees in the unit showed signs of significant mortality that were the result of two previous weather events in 2015: the hot drought and damaging ice storm. Many of the Douglas-firs that succumbed to mortality also showed signs of sap rot (decay) on the boles (i.e. trunks) of the trees. These factors played into our decision to use a VRRH management approach because the trees had to be salvaged, and the storm and insect damage had created many snags ideal for wildlife use. This stand also stood adjacent to a road heavily for recreation, thus safety and aesthetics were additional factors. Additionally, the harvest would be highly visible from Highland Avenue near Crescent Valley High School.

The second VRRH unit was Davie Crockett 2, which we wrapped up in June 2021. This unit was 12.5 acres and 74 years old. Davie Crockett 2 primarily contained even-aged Douglas-firs with a smaller component of bigleaf maple and grand fir. We chose this unit for a VRRH demonstration because it also was in a highly used recreation area and the retention of trees could help reduce the view of exposed tree boles or bare ground.

Figure 1. LiDAR vicinity map of Bingo VRRH unit and viewpoint from Nazarene Church on Highway 99.
Figure 2. Simulated image from LiDAR drone data depicting what Bingo VRRH would look like from Nazarene Church if it had been clear cut.

A major goal for the Bingo and Davie Crockett 2 harvests was to minimize the post-harvest appearance of upslope tree boles and bare ground from the surrounding valley. If you were to use binoculars to view the Bingo harvest unit from Crescent Valley High School or from the Nazarene Church on Highway 99, our hope was that you would not be able to see much bare ground or tree boles (Figure 1 and 2). We tried to achieve this by including enough retention trees in the units so that their crowns would block the view of these post-harvest features. In forestry, we call the area that a harvest unit can be viewed from the “viewshed”. We used LiDAR technology (Light Detection And Ranging), a remote sensing technique, to simulate images of what each unit would look like under different tree retention scenarios. LiDAR works by emitting pulses of light waves which bounce back to the device; in this case we used a drone. The time needed for the wavelengths to bounce back are used to calculate the distance an object (tree, road, or ground surface) is from the sensor, which can then be used to generate an image of the landscape. Graduate student Bryan Begay and OSU College of Forestry professor Bogdan Strimbu helped gather the data necessary to create the simulated images. Forest director Stephen Fitzgerald brought them into the field to help identify retention patches that would best meet our visual objectives.

We consider the visual aesthetics of harvest operations from multiple scales. For example, the Bingo unit is located on the 600 road, which is a highly-trafficked recreation area with the Bombs Away trail traversing through the unit. Davie Crockett is similarly traversed by the Vineyard Mountain trail and many users hike or bike by the unit’s edge on the 500 road every day. We wanted to make sure the final product was visually appealing from miles away as well as from the adjacent roads and trails. Often our recreation department will visit a harvest site during the planning phase to visualize and anticipate how the post-harvest area will be experienced as a runner, walker, equestrian, or biker. These experiential and aesthetic factors also play into our decision making for selecting retention trees and clumps of trees.

The process for selecting retention trees, especially for a VRRH approach, is very methodical and specific. Trees left behind often include a mixture of live hardwoods, healthy conifers, as well as standing dead conifers (snags) that are important for wildlife habitat. Many of the trees that we retain, especially when thinking about aesthetics, have large crowns (i.e. over half of the tree has a full living canopy), and consist of Douglas-firs and bigleaf maples. We retained over 100 trees for both units. For recreationists, we sought to retain trees that anchored the trail and/or provided shade for visitors.

To visualize and anticipate the spatial arrangement of the retained trees (sometimes called leave trees or wildlife trees), we use GIS technology. We take detailed maps out to the field on a tablet that contains a georeferenced mapping application (e.g., Avenza). This application allows us to drop “pins” that mark the location of the chosen retention trees. We also physically mark all retained trees with a pink painted “W” or with a permanent blue “wildlife tree” tag. This process is iterative; it is important to continually visualize and anticipate what the stand will look like after the harvest is completed. When I’m in the field doing tree marking, I am constantly keeping this in mind.

(B) Picture from highway 99 depicting what Davie Crockett 2 looks like post-harvest. Unit boundary is approximately within the white oval

My own role in creating the design and layout for these harvests was composed of fieldwork, assisting with retention tree identification, and helping with contract administration post-operation. Working on these units was an incredible learning experience for my future career. Every time I am exposed to a different management technique or harvesting styles, I am able to think more critically and holistically about forest management approaches.

Back in late April, OSU Research Forests had the exciting opportunity to plant native pacific aspens along the 600 road in the Oak Creek area of the McDonald Forest, as well as at the Marchel Tract near the Willamette River. Several were also planted near the new Peavy building on campus at OSU. College of Forestry Professor Steve Strauss and others used DNA sequencing to show that the aspens in the Willamette Valley, and nearby Washington and British Columbia, belong to a distinctive variety that grows in wet areas in the lowland Pacific. These types of areas were likely to be more abundant prior to the draining and leveling of the Willamette Valley for agriculture.

The DNA studies showed that these trees are clearly distinct from aspen in the Cascades, the Rocky Mountains, and the eastern USA and Canada. Strauss and others published these findings last year in the journal Ecology and Evolution. The authors inferred that the likely origin of this aspen was in an ice-free Pacific refugium during the last ice age.

Through a collaboration with the wholesale tree nursery, J Frank Schmidt & Son, the Strauss team’s aspen collections are currently being tested for release as a native variety. The trees planted on campus and on the Research Forests were mostly the result of samples taken by CoF staff member Anna Magnuson (supported by grant funds from Schmidt). The plantings include native trees from as close by as Peoria and the Calapooia River near Corvallis, Killen Marsh near Banks, and the Nature Conservancy’s Camassia Natural Area close to East Linn. Several other Willamette Valley origins are also represented in the plantings.

These aspens will be studied as they grow to see if they are better adapted to local conditions than the mountain aspens that are now commonly planted. J Frank Schmidt & Son plans to have them ready for distribution in a few years. Hopefully this beautiful looking, beautiful sounding, and formerly common tree in the Valley becomes more widely enjoyed by everyone. Educational materials will be installed near some of the trees once they become established.
