Value & Sustainability
- Estimated Market Value

- Wood Age Estimate
- Freshly milled or relatively new stock (less than 1 year); shows minimal oxidation or patina, exhibiting typical kiln-dried brightness.
- Sustainability Status
- Not listed on CITES or IUCN Red List; widely available, FSC certified, and considered a highly sustainable renewable building resource.
Common Uses
General construction framing, dimensional lumber, pallets, crates, and basic DIY utility projects.
Geographic Origin
Northeastern United States and across Canada (Transcontinental Spruce-Hardwood Boreal Forest).
Workability
Easy to work with both hand and machine tools; very easy to nail and screw, though can be prone to splintering on rough-sawn edges and some pitch buildup on blades.
Finish Recommendations
Best suited for paint or solid stains in construction; if used for furniture, a wood conditioner is recommended before staining to prevent blotching.
Notable Features
Mild resinous scent when cut; lightweight with a high strength-to-weight ratio for its density; may contain small resin canals.
