No one loves mushrooms as much as Ray Van Court loves mushrooms.

Their favorite food? Matsutake mushrooms. Their favorite hobby? Mushroom hunting. Their favorite time of the year? Mushroom season.

In fact, Van Court loves mushrooms so much they quit their corporate job to pursue ways to make the world a better place through fungi.

As a PhD candidate in wood science and graduate research assistant, Van Court is working on a project with assistant professor of forest-based bio-products Gerald Presley. Together, they use ectomycorrhizal fungi to bioremediate heavy metal-treated wood waste.

“Preservatives are critical to retaining the structural integrity of wood, but disposal of treated wood is problematic,” Van Court says. “Wood treated with metals including arsenic and copper is disposed of in landfills, often unlined, where these toxic metals can move into the environment. Preventing the migration of these metals, and potentially recovering them, could reduce the ecological impact of these contaminants.”

Certain species of ectomycorrhizal fungi are known to tolerate high metal environments, and initial work has shown that they may reduce metal toxicity. These mechanisms include binding them, transporting them, and producing compounds that stabilize the metals. Introducing fungi particularly adept at immobilizing metals in contaminated sites could reduce the environmental impact of toxic metal migration. The resulting retention of bound metals may also allow for reclamation.

This, says Van Court, represents a long-term solution to the problem of treated wood waste with little required inputs – all ectomycorrhizal fungi need is trees to associate with.

To test this idea, Van Court and Presley are performing a multi-stage lab experiment, screening 20 different species of ectomycorrhizal fungi in plate culture against three toxic metals.

“This screening will identify which species best tolerate and uptake metals used in wood preservatives and is an enormous increase in species and metals compared to previous research,” says Van Court.

In the second stage of the research, trees will be inoculated with the best performing fungi and planted in heavy metal-treated mesocosms, controlled containers that replicate natural environments. Trees and fungi will grow together in the metal contaminated system for a few months, after which their effect on metal will be measured. This initial work will test the effectiveness of the fungal system and pave the way for future field research.

While doing the research, Van Court was surprised by the scarcity of technologies related to ectomycorrhizal fungi and the limited knowledge on fungi growth. The fungi are usually in symbiosis with trees and for many species very little is known regarding how to replicate what the tree or other organisms in the ecosystem typically provide to the fungus.

“Admittedly, they are much harder to grow and maintain than decay fungi, but they represent a lot of untapped potential,” Van Court says. “As all kinds of products – from medicines to packaging material – have come from decay fungi, what new sustainable products might come from ectomycorrhizal ones? With new analytical and genetic tools, I think we are poised to learn much more about these fungi, and I am excited to see where this research and other projects can go.”

Nathan Vega, an undergraduate student double majoring in renewable materials and forestry, has always had an interest in the fields of renewable energy and forest-based bioenergy.

“I am especially interested in biochar for its potential to help with wildfire prevention, energy production and agricultural management,” Vega says.

Biochar is a carbon-rich, charcoal-like substance made by burning organic material, like agricultural or forestry waste, at low oxygen levels in a process called pyrolysis. Biochar can be used as a soil enhancer or as a way to sequester carbon. The energy or heat created during the conversion can also be captured and used as clean energy.

“Biochar is part of something called the circular economy,” Vega says. “And the foundation of this economy is a transition to renewable energy and materials.”

An alternative to the traditional linear economy, the circular economy is restorative or regenerative by design. It seeks to reduce waste and material use, recover resources at the end of a product’s life, and channel them back into production, significantly reducing pressure on the environment.

Vega jumped at an opportunity to work within the circular economy, assisting Scott Leavengood, director of Oregon Wood Innovation Center, in testing Portland, Oregon, based Sankofa Lumber’s new line of panel products known as “SecondStory.”

“SecondStory” panels are unique in that they are composed of reclaimed structural building materials, including lumber, oriented strand board (OSB) and plywood. Sankofa refers to these panels as architectural surfaces and advises using them for purposes like flooring, casework and wall cladding. “SecondStory” panels are currently installed in the Oregon State women’s gymnastics facility locker room.

Leavengood and Vega tested the panels to determine qualities like hardness, bond and bending strength and moisture performance. They measured the panels’ performance based on comparable products like
particleboard, medium-density fiberboard (MDF) and hardwood plywood. The Cascadia CleanTech Accelerator, powered by VertueLab and CleanTech Alliance, funded the testing.

“For entrepreneurs working with any kind of new material or new product, the first question they always get from potential customers is ‘what’s it like?’ or in other words, how does the product compare to what’s on the market now?’ says Leavengood. “We were able to help Sankofa Lumber answer these questions since Nathan put the product through a workout.”

Bond strength is critical for composite products. Leavengood and Vega found the strength excellent even after products were exposed to high humidity and water submersion for several days.

Focusing on his classes and assisting Leavengood with his research projects provided Vega with support and something to focus on during the pandemic.

“Everyone at the College of Forestry was very welcoming and friendly,” Vega says, “Plus, this job was a great part of the last year-and-a-half as it let me get out of the house and listen to music while I did the experiments.”

Vega is a recipient of the Friends of Renewable Materials Seneca Scholarship, Powers Scholarship, and Presidential Scholarship from the College of Forestry. He said receiving the scholarships has been essential to ensuring his success at Oregon State.

“These scholarships have allowed me to pursue my education without distraction or worry,” Vega says. “It’s been such a relief to find that I am so supported.”

When Vega is not studying, he likes to spend his free time reading, gardening, cooking, listening to music, hiking and playing the drums. He also likes to spend his time with his friends and family and he recently joined the college’s logging sports team.

After graduation, Vega wants to work in bioenergy, specifically biochar production from forest biomass as a carbon-negative energy source.

Caitlyn Reilley has worn many hats during her time at Oregon State University.

First, she was an undergraduate pursuing a career as a clinical dietician. Then, after realizing how heavily social, economic, and environmental factors influence individual health outcomes, she switched gears to focus on community-level health. She graduated with a bachelor’s degree in public health in 2016, securing a job as an outreach coordinator for the Linus Pauling Institute, a nutrition research institute at OSU.

While working as the outreach coordinator, Reilley began eyeing opportunities to return to school to study environmental policy. She learned about the opportunity to join the College of Forestry as the coordinator for the Elliott State Research Forest project.

“The Elliott project coordinator role was such a unique opportunity to bring my skillset to a project situated at the intersection of public lands policy, natural resource management, and rural community well-being,” Reilley says. “It was also fulfilling to help the College envision a path forward for the Elliott that benefits local communities while providing critical research into the best way to deliver the myriad of social, economic, and ecological values our forests provide.”

According to Reilley, developing a proposal for a research forest was often messy and included many difficult conversations. Overall, however, it was a joyful experience for her and gave her confidence in the ability of humans to work together to solve complex natural resource issues.

It also confirmed her desire to study natural resources management. As a current graduate student in sustainable forest management with a concentration in economics and policy, Reilley is working with Mindy Crandall, assistant professor of forest policy and economics. Crandall’s research focuses on the role that natural resources, especially forests, play in human well-being.

Together, she and Crandall are a part of a collaborative project studying the human dimensions of wildfire with researchers at the Forest Service Pacific Northwest Research Station. Her master’s research explores community vulnerability to wildfire and the social drivers of human-caused fire ignitions.

“The majority of fires in Oregon are started by people, and research into what drives these human-caused fires can help inform fire prevention strategies,” Reilley says.

Reilley’s research into socially vulnerable populations allowed her to support the implementation of Senate Bill 762 (SB 762), Oregon’s omnibus wildfire bill allocating millions for landscape scale forest restoration and community wildfire preparedness projects.

“As a part of this project, we are identifying and mapping socially vulnerable communities to help allocate resources provided by SB 762,” says Reilley. “Not all communities are equally equipped to prevent or respond to wildfire and it has been really encouraging to see how much interest there is in using this type of data to prioritize funding and support for communities that need it most.”

When Reilley is not in front of her computer analyzing data, she is in the forest and enjoys long-distance running and mountain biking with her Australian shepherd pup Ginger.

“Thanks to a rigorous Ginger-driven training plan, I was able to complete my first Ironman triathlon last summer in Coeur D’ Alene, Idaho,” Reilley says. “I also recently started building live edge furniture. I love to hunt for unique slabs of wood and am slowly building my arsenal of power tools.”

“I’ve learned so much from working with College of Forestry faculty these past three years. The Elliott project and implementation of SB 762 have provided incredible opportunities to see first-hand how the research informs real world management and policy decisions that promote healthy ecosystems and communities. Oregon communities are really at the heart of the work I’ve been able to be a part of here in the College, and I feel so fortunate for that.”

As the recipient of two scholarships from the College of Forestry: the Hal Salwasser Fellowship and the Lu Alexander Graduate Fellowship, Reilley is looking forward to using her scholarships to present her research at conferences this spring. After graduating this summer, she plans to continue working in the wildfire policy realm and hopes that her future career path never takes her too far from her home here in Oregon.

Lara Jacobs is bringing into focus the ecological and pathogenic impacts of outdoor recreation using a cultural impact lens.

Jacobs, who is pursuing her PhD in forest ecosystems and society, works collaboratively with a Tribe in Washington to examine how fecal matter from outdoor recreationists may create issues to the Tribe’s food supply.

Jacobs says that most people do not understand that when they deposit fecal matter in parks and protected areas, it may pose issues to watersheds, soils, and animals, including humans.

“We’ve been taught for years just to dig a hole and bury fecal matter,” says Jacobs. “However, this contrasts with the scientific literature that shows how bacteria survive in great abundance across seasons, and depth of burial doesn’t seem to matter. The best practice isn’t to bury your fecal matter unless you plan to put in a lot of work to completely compost it with soil. Outdoor recreationists should be packing out their fecal waste whenever possible.”

This research is vital for multiple reasons, including the Treaty obligations that the U.S. government holds to manage the Tribe’s non-reservation lands in manners that maintain their natural resources, including subsistence foods.

“This research is also critical because the field of recreation ecology has yet to bring in a cultural impact lens,” says Jacobs.

As a citizen of the Muscogee (Creek) Nation of Oklahoma who also has Choctaw heritage, Jacobs graduated magna cum laude from Oregon State University with a bachelor of science degree in women studies. The degree combined her interests in environmental issues with topics about systems of oppression and privilege. She also holds a master’s degree in environmental studies from Prescott College, focusing on environmental education, conservation science, and sustainability.

After completing her master’s degree, Jacobs wanted to continue researching outdoor recreation science but was more interested in the ecological impacts of outdoor recreation.

“There are five recreation ecology lab groups at universities worldwide, four of which are in the U.S., and one at OSU,” says Jacobs. “Dr. Ashley D’Antonio’s recreation ecology lab group is where the best GIS work is coming from in this field. So, it was a natural choice for me to apply to be in her lab group.”

Her doctoral research centers on the spatial mapping of outdoor recreationists’ behaviors and their associated environmental ecological and pathogenic impacts on Native lands managed by the National Park Service. Jacob’s main objective is to bring an inclusive lens to academia and help transform the academic landscape into a better and brighter place for everyone. While at OSU, she’s worked to build bridges across the college to create spaces for Indigenous students to connect on various topics.

She co-founded the Traditional Ecological Knowledge club and is the current chair and graduate student representative. Jacobs reestablished an OSU chapter of the American Indian Science and Engineering Society and currently serves as president. She is secretary of the Indigenous Grad Student Alliance, and for the past year, she served as a member of the Indigenous Involvement Work Group for the George Wright Society. Jacobs is also a Ford Foundation Predoctoral Fellow, ARCS Scholar, Cobell Scholar, Native Nations Institute Awardee, Helen J. Harold Gilman Smith Scholar and Thurgood Marshall Scholar.

Jacobs says one of the best things about her graduate program has been working with her advisor, Dr. D’Antonio.

“She provides an excellent example for how mentorship of graduate students can occur through positive and supportive interactions,” says Jacobs. “I model my mentoring of students based on her actions.”

During her spare time, Jacobs loves to hike, backpack, kayak, and explore different ecosystems. She also enjoys time with family.

“Family means so much to me, and so does my culture,” says Jacobs. “I work with a cultural guide to connect with my Tribe and spend time learning our Mvskoke language and histories. I also love to create beadwork that is inspired by my people and our connections with the land. In the summer, I spend my time gardening and harvesting foods and medicines. In fall, I spend countless hours canning, drying, and preparing food for my family and Tribal Elders.”

The College of Forestry has supported Jacobs’ education through multiple scholarships, including covering equipment costs for her research.

After finishing her degree, Jacobs aspires to continue working in academia as a professor.

“My dream is to continue building knowledge about how outdoor recreation impacts Tribal Communities and generate more information about recreation impacts in marine systems,” says Jacobs. “I plan to establish a lab group where I can dedicate space and time to mentoring Indigenous students and others from marginalized communities, including allies.”

Indigenous women make up the smallest percentage of assistant, associate, and full professors nationwide (less than one-half of one percent). Jacobs hopes to use her position to show other Indigenous and marginalized people that they, too, belong in the academy and help them realize their potential and achieve their dreams.

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.
