Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight, flat-sawn with prominent cathedral figure. Earlywood and latewood are clearly distinct, with latewood appearing as darker, reddish-brown bands.
Color Description
Light brown to reddish-brown heartwood with a yellowish sapwood. It typically darkens with age and exposure to light, developing a deeper orange-red patina.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable regarding decay resistance; susceptible to insect attack.
Common Uses
Residential and commercial construction, heavy beams, flooring, cabinetry, interior trim, and boat building.
Geographic Origin
Native to Western North America (Pacific Northwest, Rocky Mountains).
Market Value & Sustainability
Estimated Market Value
$6.00 - $12.00 per board foot for select or vertical grain grades.
Wood Age Estimate
Based on the uniform coloration and surface texture, this appears to be modern dimensional or finish-grade lumber, likely within the last 5-15 years.
Sustainability Status
Not CITES listed; classified as Least Concern by IUCN. Widely available as FSC-certified.
Workability
Generally easy to work with hand and machine tools, though it can splinter or tear out if tools are dull. Glues, stains, and finishes well, though large latewood bands can cause uneven absorption.
Notable Features
Features a distinct resinous scent. Known for having one of the highest strength-to-weight ratios among softwoods.
Finish Recommendations
Urethane or lacquer for protection, or penetrating oils to highlight the natural cathedral grain. A sanding sealer or pre-stain conditioner is recommended to prevent blotchiness.
Identification Confidence
High; the characteristic contrast between the latewood and earlywood, the orange-red tint, and the specific cathedral arch pattern are highly indicative of flat-sawn Douglas Fir.
