Intentional Wood Sourcing
Sustainable Northwest is the region’s premier source of information and expertise about intentional wood sourcing. We connect the built environment to the healthy forests and people who produce wood products. We do this by helping builders and building owners buy responsibly harvest, local wood that supports community and conservation values.
Here are videos highlighting a few of our partners working in sustainable forestry and wood products manufacturing.
Yakama Forest Products

Yakama Forest Products (YFP) contributed 20% of the wood in the glulam beams at the Portland International Airport’s new main terminal, which opened in 2024. YFP is a tribally owned sawmill operated by the Yakama Nation. It produces high-quality lumber and veneer from sustainably managed reservation lands. With 240 employees, 90% of whom are tribal members, YFP provides vital employment to the Yakama community. The company plays a key role in supporting the Yakama Nation’s economy and preserving the land for future generations.

F.H. Stoltze Land & Lumber Co. contributed lumber for the mass timber products manufactured by Smartlam and installed at the Hewlett Packard WAV facility in Vancouver, Washington.

Established in 1912, we are the oldest family-run lumber company in the state, producing high-quality wood products while sustainably managing forestlands.

Coquille Indian Tribe
-
The Coquille Tribe provided high-quality, Douglas-fir timber for portions of the glulam beams used in the new Portland International Airport’s main terminal roof. This timber is harvested on an 80-year rotation, meaning their logs grow longer to store more carbon than in a typical commercial forest. The Coquille Tribe prides itself on management of their ancestral lands on Oregon’s South Coast.
Herbert Lumber purchased the Coquille logs and kept them separate from all other logs throughout the supply chain. Zip-O Log Mills milled them into lamstock, and then Zip-O-Laminators processed them into glulam beams.
