Value & Sustainability
- Estimated Market Value
- $0.60 - $1.20 per board foot (lumber yard rate for dimensional framing).
- Wood Age Estimate
- Freshly milled; less than 1 year since processing based on bright color and lack of oxidative graying.
- Sustainability Status
- Least Concern (IUCN); widely available and harvested from sustainably managed forests, often FSC certified.
Common Uses
General construction framing, pallets, crates, structural lumber (2x4s), and low-cost utility wood.
Geographic Origin
Northern North America (Canada and Northern United States).
Workability
Easy to cut and nail, though prone to splintering as seen in the image; glues and finishes well, but can be susceptible to pitch pockets.
Finish Recommendations
Generally left unfinished for framing; if used for furniture, requires a wood conditioner before staining to prevent blotchiness. Polyurethane or paint is common.
Notable Features
Mild resinous scent; lightweight with high strength-to-weight ratio for construction; exhibits fuzzy grain when machined with dull blades.
