Southern Yellow Pine
Pinus spp. (e.g., Pinus echinata, Pinus elliottii, Pinus palustris, Pinus taeda) • Softwood
Grain Pattern
Straight grain with a coarse, uneven texture. The sample shows distinct growth rings with a sharp transition between earlywood and denser latewood, common in flat-sawn utility lumber.
Color Description
Heartwood is typically reddish-brown, while sapwood is yellowish-white. This specific sample exhibits a golden-yellow to mustard hue, likely due to a combination of natural oxidation and possibly a topical pressure-treatment chemical or stain.
Hardness Rating
690 lbf (Soft to Medium-Soft)
Durability Rating
Slightly durable to non-durable regarding rot resistance unless pressure-treated. High sapwood content makes it susceptible to fungal attack in outdoor environments without treatment.
Common Uses
Residential and commercial construction, framing, trusses, decking (when treated), flooring, and utility-grade furniture.
Geographic Origin
Southeastern United States
Market Value & Sustainability
Estimated Market Value
$0.80 - $1.50 per board foot (standard dimensional lumber pricing)
Wood Age Estimate
Relatively recent, likely less than 5 years old. The fibrous splintering on the edge and the lack of deep silvering suggests it has not been weathered for an extended period.
Sustainability Status
Highly sustainable; widely available and intensively managed in plantations across the Southern US. Not listed in CITES or IUCN Red List.
Workability
Easy to work with both hand and machine tools, though the resin can gum up blades and sandpaper. It holds nails and screws well but is prone to splintering as seen in the fractured edge of the sample.
Notable Features
Distinctive resinous odor; contains high amounts of pitch/resin. It has a high strength-to-weight ratio among softwoods.
Finish Recommendations
Accepts most finishes well, but a sanding sealer or conditioner is recommended to prevent blotchiness. If for outdoor use, a UV-resistant penetrating oil or solid-color stain is best.
Identification Confidence
High/Medium. The pronounced grain contrast, color, and typical splintering pattern are characteristic of Southern Yellow Pine utility lumber as used in North American construction.
