Value & Sustainability
- Estimated Market Value
- Moderate, typically ranging from $2.00 to $4.00 per board foot depending on grade and dimensions.
- Wood Age Estimate
- Estimated to be 10 to 30 years old based on surface wear, weathering, oxidation patterns, and common dimensional lumber characteristics.
- Sustainability Status
- Not CITES listed and generally considered of least concern by the IUCN. Readily available through sustainably managed forests and commercial plantations, often certified by the FSC.
Common Uses
Construction and framing, plywood, exterior decking, flooring, beams, doors, and general millwork.
Geographic Origin
Western North America, particularly the Pacific Northwest and the Rocky Mountain regions.
Workability
Generally works well with both hand and machine tools. Planes and shapes easily, though the sharp contrast between soft earlywood and hard latewood can sometimes lead to uneven sanding or minor tearout if tools are not sharp.
Finish Recommendations
Accepts stains, paints, varnishes, and penetrating oils well. For outdoor use, UV-resistant exterior finishes or sealers are recommended to prevent graying and moisture absorption.
Notable Features
High strength-to-weight ratio, pronounced growth ring contrast, slight resinous scent, and contains natural tannins that can react with certain metals in damp conditions.
