460 lbf (Very Soft)
Durability & Decay Resistance
Slightly Durable to Non-durable. Susceptible to rot and insect attack if left untreated in moist conditions.
Value & Sustainability
- Estimated Market Value
- $1.50 - $3.00 per board foot for utility grade
- Wood Age Estimate
- 30-50 years based on surface oxidation, secondary patina, and the presence of aged blue-stain fungi.
- Sustainability Status
- Least Concern (IUCN); widely available and not CITES listed.
Common Uses
Construction lumber, utility shelving, crates, boxes, and residential framing.
Geographic Origin
Western North America (Pacific Northwest and Rocky Mountains)
Workability
Easy to work with hand and machine tools. Softness makes it prone to indentations and fuzzy surfaces if tools are dull. Glues and finishes well but can be resinous.
Finish Recommendations
Penetrating oil or film-building polyurethane after thorough sanding to remove oxidized fibers and staining.
Notable Features
Distinctive resinous scent when cut; presence of blue stain (sapstain) which does not affect structural integrity but impacts aesthetics.
