Douglas Fir (Old Growth)
Pseudotsuga menziesii • Softwood
Grain Pattern
Vertical grain (quartersawn) with exceptionally tight, straight, and uniform growth rings characteristic of old-growth timber. No visible figure or knots.
Color Description
Heartwood is a light yellowish-tan to reddish-brown; sapwood is narrow and pale. Exhibits high luster and will darken significantly to a deeper orange-red over time with light exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay and rot, though less than Cedar or Redwood. Susceptible to insect attack.
Common Uses
High-end joinery, flooring, window frames, door components, veneer, and boat building for its high strength-to-weight ratio.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
Approximately $12.00 - $18.00 per board foot for high-grade vertical grain old growth.
Wood Age Estimate
The board shows signs of modern milling but likely originated from a tree several centuries old given the ring density. Minimal oxidation suggests recent surfacing.
Sustainability Status
Not CITES listed; IUCN Least Concern. However, old-growth stands are increasingly protected and sought after for their superior quality, often FSC certified.
Workability
Generally works well with both hand and machine tools, though the hard latewood bands can cause uneven sanding or 'ridging'. Glues and finishes well.
Notable Features
Distinctive resinous, sweet odor when worked. High strength-to-weight ratio and excellent dimensional stability due to the vertical grain orientation.
Finish Recommendations
Polyurethane or lacquer to preserve the grain; clear oils will deepen the golden hues. Avoid heavy stains which may blotch or obscure the tight grain.
Identification Confidence
High; the combination of the reddish-orange hue, distinct latewood bands, and the extreme ring density/vertical grain orientation is classic for high-grade Douglas Fir.
