Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight and plain; clear growth rings showing abrupt transition from lighter earlywood to darker latewood with a flat-sawn appearance on the visible faces.
Color Description
Heartwood is typically a light reddish-brown and is visible here as a pale yellowish-tan due to light exposure; sapwood is narrower and lighter. It darkens significantly to a deeper orange-red over time.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack without treatment.
Common Uses
Heavy structural timber, flooring, cabinetry, interior trim, furniture, and plywood.
Geographic Origin
Western North America (Pacific Northwest ranges from British Columbia to California).
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot for clear vertical grain (CVG) or high-grade select stock.
Wood Age Estimate
Relatively modern stock (less than 10 years) based on the clean saw marks, lack of significant oxidation/graying, and sharp edges.
Sustainability Status
Least Concern (IUCN); widely available and harvested from sustainably managed forests; FSC certification is common.
Workability
Generally works well with both hand and machine tools, though it can be prone to splintering and tearout during machining. Gluing and finishing properties are good, but it can be resinous.
Notable Features
Distinctive resinous, sweet scent when cut; known for having one of the highest strength-to-weight ratios of any softwood species.
Finish Recommendations
Oil-based polyurethane or lacquer; a sanding sealer is often recommended to ensure even stain absorption due to the porous earlywood.
Identification Confidence
High; the characteristic growth ring structure, color tone, and typical North American construction timber dimensions strongly indicate Douglas Fir.
