Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Typically straight and plain, with a medium to coarse texture. The vertical grain (quarter-sawn) shown in the image exhibits tight, parallel growth rings with a distinct transition between earlywood and latewood.
Color Description
Heartwood is typically a light reddish-brown and the sapwood is yellowish-white. It tends to darken or redden over time upon exposure to UV light. Low to medium luster.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack. It performs well in structural outdoor settings if properly treated.
Common Uses
Veneer, plywood, structural timbers, flooring, cabinetry, interior trim, and boat building.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$3.00 - $7.00 per board foot depending on grade (Vertical Grain vs. Flat Grain) and regional availability.
Wood Age Estimate
The sample appears to be seasoned but relatively modern, likely cut within the last 5-10 years based on the lack of deep oxidation or heavy patina.
Sustainability Status
Not on CITES Appendices or IUCN Red List. Widely available as FSC certified and considered a sustainable choice due to fast growth and managed forests.
Workability
Generally works well with both hand and machine tools, though it can be prone to splintering and tearout because of the density difference between earlywood and latewood. It glues and finishes well.
Notable Features
Distinctive resinous scent when worked. It possesses a very high strength-to-weight ratio for a softwood, making it a primary choice for North American construction.
Finish Recommendations
Responds well to film-forming finishes like polyurethane or lacquer. If staining, a pre-conditioner is highly recommended to prevent blotching due to uneven absorption.
Identification Confidence
High; the reddish-orange hue combined with the very distinct, straight growth rings and the context of the lumber pile typical of North American workshops strongly indicates Douglas Fir.
