Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Primarily straight grain with prominent, slightly wavy growth rings. The sample shows a transition from flat-sawn to rift-sawn orientation, displaying distinct latewood/earlywood contrast.
Color Description
Light reddish-tan heartwood with yellowish-white sapwood. Subdued luster. Shows typical darkening or 'pinking' over time with UV exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but susceptible to insect attack. Requires treatment for ground contact.
Common Uses
Veneer, plywood, structural timber, flooring, trim, cabinetry, and boat building.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (Vertical Grain commands a premium).
Wood Age Estimate
Freshly milled or recently surfaced, likely under 2 years old based on lack of significant oxidation or surface grime and the sharpness of the grain lines.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and frequently FSC certified as it is a major timber crop.
Workability
Generally works well with machine and hand tools, though the hardness difference between earlywood and latewood can cause uneven sanding and 'washboards' if care is not taken.
Notable Features
Distinctive resinous scent when worked. Known for its high strength-to-weight ratio among softwoods and high resin content.
Finish Recommendations
Takes clear coats, oils, and lacquers well. Using a sanding sealer or wood conditioner is recommended before staining to prevent blotchiness due to varied density.
Identification Confidence
High; the characteristic 'abrupt' transition between earlywood and latewood, the light orange/reddish hue, and the distinct softwood texture are diagnostic for Douglas Fir.
