Common Name(s): Douglas-Fir
Scientific Name: Pseudotsuga menziesii
Distribution: Western North America
Color/Appearance: Can vary in color based upon age and location of tree. Usually a light brown color with a hint of red and/or yellow, with darker growth rings. In quartersawn pieces, the grain is typically straight and plain. In flatsawn pieces, (typically seen in rotary-sliced veneers), the wood can exhibit wild grain patterns.
Grain/Texture: Grain is generally straight, or slightly wavy. Medium to coarse texture, with moderate natural luster.
Endgrain: Small to medium sized resin canals, infrequent and variable in distribution; solitary or in tangential groups of several; earlywood to latewood transition abrupt, color contrast high; tracheid diameter medium-large.
Workability: Typically machines well, but has a moderate blunting effect on cutters. Accepts stains, glues, and finishes well.
Pricing/Availability: Should be widely available as construction lumber for a modest price. Old growth or reclaimed boards can be much more expensive.
Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.
Common Uses: Veneer, plywood, and structural/construction lumber.
Comments: Named after Scottish botanist David Douglas, (though the scientific name is in honor of Archibald Menzies, who first described the tree in the 1790s). Douglas-Fir is technically not a true Fir (Abies genus), but is in its own genus: Pseudotsuga.
The tree itself grows to be very large, and yields a large amount of usable lumber and veneer for plywood. It is an incredibly valuable commercial timber, widely used in construction and building purposes. The wood is very stiff and strong for its weight, and is also among the hardest and heaviest softwoods commercially available in North America.
