Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Pronounced straight grain with distinct latewood bands. Displays visible end grain growth rings that are tight and uniform, suggesting old-growth or high-altitude harvesting. The texture is medium to coarse.
Color Description
Heartwood ranges from light reddish-brown to a yellowish-orange. The sapwood is a paler yellowish-white. It darkens significantly over time into a deep reddish-orange or amber color when exposed to UV light.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers moderate resistance to rot and decay, though it is susceptible to insect attack. It is highly valued for structural stability.
Common Uses
Heavy structural timbers, framing, flooring, cabinetry, interior trim, veneer, and boat building.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains) and widely naturalized in Europe and Oceania.
Market Value & Sustainability
Estimated Market Value
$5.00 - $9.00 per board foot for high-grade or clear vertical grain (CVG) material.
Wood Age Estimate
The tight growth rings suggest a tree over 100 years old. The surface oxidation indicates the timber has been cut and exposed for 10-20 years.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and commonly FSC certified from managed forests.
Workability
Generally easy to work with hand and machine tools, but can be prone to splintering and 'shell-out' of the softer earlywood during sanding or machining. Glues and finishes well.
Notable Features
Distinctive resinous, sweet scent when cut. High strength-to-weight ratio for a softwood. Notable for its large available dimensions and straightness.
Finish Recommendations
Takes stains and clear coats well. A sanding sealer is recommended to prevent uneven absorption between latewood and earlywood bands. Polyurethane or penetrating oils are excellent choices.
Identification Confidence
High; the distinct 'ribbed' latewood bands, reddish-orange hue, and lack of visible resin canals found in pine strongly identify this as Douglas Fir.
