Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight to slightly wavy grain with a coarse, uneven texture. The sample shows a flat-sawn cathedral pattern on the left and vertical growth rings toward the right.
Color Description
Heartwood ranges from light brown to a reddish-orange hue with strong contrast between earlywood and latewood. Sapwood is yellowish-white. This sample shows significant graying and weathering due to outdoor exposure or age.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; heartwood is resistant to decay but susceptible to insect attack. Fairly resistant to moisture and weathering compared to other softwoods.
Common Uses
Structural framing, heavy timber construction, flooring, cabinetry, veneer, and exterior millwork.
Geographic Origin
Native to Western North America (Pacific Northwest, Rocky Mountains)
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (Select Structural or Clear Vertical Grain command higher prices).
Wood Age Estimate
The wood appears to be roughly 10-20 years old based on the extent of oxidation and surface weathering, suggesting long-term exposure to the elements.
Sustainability Status
Least Concern (IUCN); widely available with FSC certification. Not listed on CITES appendices.
Workability
Generally easy to work with both hand and machine tools, though it can exhibit tearout during planing if tools are not sharp. Holds nails and screws well but can split without pilot holes. Glues and finishes adequately.
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
Penetrating oils or exterior stains are recommended for weathered samples. If used indoors, polyurethane or lacquer work well once the surface is sanded to remove oxidized fibers.
Identification Confidence
High; the distinct contrast between the hard, dark latewood bands and the lighter earlywood, combined with the cathedral grain and visible weathering patterns, is classic for Douglas Fir.
