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