Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight but wavy around knots; flat-sawn displaying typical latewood/earlywood growth ring contrast and characteristic elliptical cathedral patterns.
Color Description
Light reddish-brown heartwood with a distinct transition to paler yellowish-white sapwood. Notable for darkening to a deeper orange-red patina over time with UV exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack if left untreated in ground contact.
Common Uses
Structural framing, heavy timbers, flooring, veneers, joinery, and boat building.
Geographic Origin
Western North America (Pacific Northwest from British Columbia to California).
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade (Vertical Grain/VG is significantly higher).
Wood Age Estimate
Modern lumber; likely kiln-dried and harvested within the last 5-10 years based on the lack of deep oxidation and fresh planer marks.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and frequently FSC certified from managed forests.
Workability
Generally easy to work with hand and machine tools, though it can be prone to splintering and tearout if tools aren't sharp. Glues and finishes well.
Notable Features
Distinctive resinous scent when cut; high strength-to-weight ratio for a softwood; prominent contrast between light earlywood and dark latewood rings.
Finish Recommendations
Clear coats like polyurethane or lacquer are recommended to showcase the grain. Takes film-forming finishes better than deep stains due to potential blotching.
Identification Confidence
High; the distinctive pinkish-orange hue combined with the tight growth rings and classic resinous knot appearance is diagnostic for Douglas Fir.
