Advancing Hardwood Viability: The Role of Foresters in Wood Origin Testing

February 12, 2025

Written by Phil Guillery

The U.S. hardwood industry stands at a critical juncture. With global markets demanding greater transparency and responsible practices, the ability to verify the origin of hardwood products has become essential. The US Forest Service International Programs and Trade is working with technologies such as Laser-Induced Breakdown Spectroscopy (LIBS), Inductively Coupled Plasma Mass Spectrometry, and Stable Isotope Ratio Analysis (SIRA) to develop new solutions, enabling precise identification of geographic origin. These advancements rely on a robust database of reference samples, which foresters are uniquely equipped to provide.

The Science Behind Wood Origin Testing

Wood origin testing uses chemical analyses to identify unique signatures, or “profiles,” derived from stable isotopes and trace elements naturally occurring in plants. LIBS, a new technology for the identification of the origin of wood, offers significant advantages for field applications. Its portability and capacity for near real-time results make it potentially ideal for on-site screening at factories, forests, or log yards. With sufficient reference material, LIBS can identify the harvest location of wood products within a 40-mile radius.

The implications of such precision are profound. These technologies provide the industry a potential means to meet stringent international regulations, such as the European Union Deforestation Regulation (EUDR) and the Lacey Act, while also distinguishing U.S. hardwoods in the global market. By verifying the origin of products, stakeholders can ensure compliance, combat illegal logging, and reinforce the reputation of U.S. hardwoods as a responsibly sourced and legally harvested material.

The Essential Role of Foresters

Foresters play a pivotal role in building the reference databases necessary for these technologies to succeed. Their expertise in species identification and access to forests and harvest sites makes them indispensable to this effort. Sampling involves collecting wood cores from living trees using increment borers or “cookies” from log ends at sawmills and log yards. These samples are then analyzed to map the chemical signatures of different wood species across regions.

The data collected by foresters underpins the accuracy and reliability of wood origin testing. A comprehensive reference library in underway for the technologies like LIBS and SIRA, enhancing the industry’s ability to trace wood to its source and differentiate U.S. hardwoods from less sustainable alternatives.

Implications for the Hardwood Industry

The adoption of wood origin testing offers substantial benefits to the hardwood industry. It provides scientific validation for the legality and sustainability of U.S. products, bolstering their appeal in international markets. This capability also addresses concerns about illegal logging, which disrupts markets and contributes to global deforestation.

Moreover, the integration of origin testing into supply chains aligns with broader efforts to enhance traceability and transparency in forestry management. As consumer demand for sustainable products grows, this technology can position the U.S. hardwood industry as a leader in responsible forestry practices and enable a new level of transparency.

Opportunities for Collaboration

Foresters interested in contributing to this initiative can play an active role in shaping the future of wood traceability. By participating in sample collection efforts, foresters support the development of a cutting-edge system that benefits both the industry and the environment. The Forest Stewards Guild and USFS are discussing ways that the Guild and Guild members can support the collection of reference samples. Stay tuned for a webinar where you can learn more about the work and find out how to participate.

This project represents a convergence of scientific innovation and practical forestry expertise. By collaborating, Guild members can help ensure the integrity of U.S. hardwood production while advancing responsible and legal forestry practices.

In September 2025, the Guild launched a three-person Forest Stewards Apprenticeship (FSA) crew to work with the Penobscot Nation’s Department of Natural Resources (PN DNR). Over the course of their six-month season, apprentices Agenor Duhon, Gabe Stewart, and Jacob Baker shared a season of learning, collaboration, and hands-on stewardship of Penobscot Tribal lands.

This week, I stepped into the role of crew leader. We worked a full 40-hour week, splitting our time between Clifton Farms and a prescribed burn operation. On the first day in the field, we completed hack-and-squirt treatments on trees that had been marked the previous week. For the remainder of the week, we focused on marking trees for future hack-and-squirt work, maintaining a steady pace and ensuring accuracy in our selections.

As Guild members, our practice is fundamentally grounded in field observation. We know intuitively that forests are dynamic, living communities. Yet, for decades, the high-level systems used to value our work, specifically the carbon accounting ledgers tied to international frameworks like the Paris Agreement, have treated forests as static, quantifiable blocks of land. In a recent commentary published in One Earth, I argue that these legacy measurement, reporting, and verification (MRV) frameworks are failing. Ledger accounting relies on crude land-use delineations and outdated technology, effectively penalizing the natural, seasonal flux of the ecosystems we manage every day. By forcing landscapes into rigid “forest” versus “non-forest” binaries, such legacy systems miss the complex reality on the ground. But a major shift is underway.

Women have always been a part of forestry. Historically, women often helped guide family decisions about when to cut, which trees to save, and how best to steward their land for the next generation. Historical accounts from the Southern Appalachians describe women’s roles in decisions about timber harvesting and prioritizing long-term forest health. These often-uncredited contributions are even reflected in Aldo Leopold’s A Sand County Almanac (1949), in which describes his stewardship philosophy informed not only by his professional experience, but by shared responsibility, where the perspectives of his wife and daughters played an important role.

Although rural regions often host the highest concentrations of public and private forest land, they typically lack the sustainable workforce necessary for active management and stewardship. How do we address this foundational problem in forest conservation?

The Forest Stewards Guild has a unique dual mandate: practice and promote forest stewardship. Personally, I think the combination of practicing forest management and promoting best practices is what makes the Guild a vibrant and impactful organization.

We celebrate the remarkable career and legacy of Leslie (Les) Benedict, who has provided visionary leadership and dedicated service to the stewardship of forests, championing the preservation of the ecological and culturally important black ash. Benedict, a member of the Saint Regis Mohawk Tribe in Akwesasne, north of the Adirondacks in upstate New York, recently retired after serving as the Assistant Director of the Tribe’s Environment Division for over 35 years.

The Forest Stewards Guild has been working to support the National Park Service on forest stewardship projects throughout the eastern U.S. This month we are in the midst of a project to protect mounds at Effigy Mounds National Monument near Harpers Ferry Iowa. This site was designated as a National Monument in 1949 and preserves over 200 mounds built between 800 and 2,500 years ago. Mounds at this site include conical, linear, compound, and effigy mounds – constructed in the shape of animals. Please see the National Park Service page for more information about the mounds, the people who built them, and how to visit the site. The lidar images on that website of the Marching Bears and other mound groups are fascinating.
