Value & Sustainability
- Estimated Market Value
- $3.00 to $6.00 per board foot for standard lumber, potentially higher for clear-grade or reclaimed stock.
- Wood Age Estimate
- Estimated to be 30 to 60 years old based on oxidation, surface wear, and weathering indicators typical of reclaimed or aged interior paneling.
- Sustainability Status
- Not CITES listed and of least concern on the IUCN Red List. Widely available through sustainable forestry and plantations.
Common Uses
Construction framing, flooring, paneling, cabinetry, doors, and heavy timber construction.
Geographic Origin
Western North America, particularly the Pacific Northwest.
Workability
Generally easy to work with both hand and machine tools, though the pronounced difference in hardness between earlywood and latewood can occasionally cause splintering or uneven planing.
Finish Recommendations
Takes stains, varnishes, polyurethanes, and oils exceptionally well, though a sanding sealer may be useful to prevent blotchiness on the softer earlywood rings.
Notable Features
Known for high strength-to-weight ratio, distinct contrasting growth rings, and a subtle resinous scent.
