Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Primarily straight with a prominent, coarse texture. The image shows a flat-sawn orientation with distinct transitions between light earlywood and darker, denser latewood bands.
Color Description
Light brown to yellowish-red heartwood with pale sapwood. It darkens and reddens significantly over time upon exposure to UV light, developing a classic amber patina.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack if left untreated in ground contact.
Common Uses
Structural framing, heavy construction, flooring, cabinetry, plywood, and exterior trim.
Geographic Origin
Native to Western North America, including the Pacific Northwest and Rocky Mountains.
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (Vertical Grain/Clear grades command higher prices).
Wood Age Estimate
Modern era; likely 10-20 years based on the lack of deep oxidation and the presence of contemporary mechanical sanding/tool marks.
Sustainability Status
Not listed in CITES or on the IUCN Red List of Threatened Species. Widely available through FSC certified sustainable forestry.
Workability
Generally works well with hand and machine tools, though latewood can be brittle and prone to splintering. It glues, stains, and finishes well, though a sealer is recommended due to resin content.
Notable Features
Features a distinct, resinous, and sweet evergreen scent. Known for its High weight-to-strength ratio among softwoods.
Finish Recommendations
Polyurethane or oil-based varnishes work best to protect the surface. A pre-stain wood conditioner is advised if staining due to the variation in density between earlywood and latewood.
Identification Confidence
High; the characteristic growth ring contrast, color, and coarse texture are hallmark indicators of Douglas Fir.
