River Birch
Betula nigra • Hardwood
Grain Pattern
Straight to slightly wavy; fine, uniform texture with closed pores. The sample shows faint pith and growth ring definition typical of young saplings.
Color Description
Light tan to cream-colored sapwood with a light reddish-brown heartwood. The sample illustrates a distinct transition from the darker outer bark/cambium to the pale inner wood. It lacks high luster and matures to a more muted yellowish-brown over time.
Hardness Rating
1,030 lbf (Medium Hardness)
Durability Rating
Non-durable; highly susceptible to decay and insect attack if left exposed to moisture or ground contact.
Common Uses
Furniture parts, plywood, veneer, crates, turned objects, and fuel wood. Often used as an ornamental landscape tree.
Geographic Origin
Eastern United States (from New Hampshire south to Florida and west to Texas/Minnesota).
Market Value & Sustainability
Estimated Market Value
Approximately $2.50 - $4.50 per board foot for dimensional lumber, though often sold as lower-cost utility hardwood.
Wood Age Estimate
Fresh cut (less than 1 year); the wood appears moist with modern rough-cleave marks and no significant oxidation or UV-induced darkening.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and considered a sustainable, fast-growing species.
Workability
Generally easy to work with both hand and machine tools, though it can experience some tearout during surfacing if the grain is wavy. Glues, stains, and finishes well.
Notable Features
Often lacks a distinct scent. Known for its characteristic papery or shaggy bark (visible in the rough edges of the sample). It has a relatively high strength-to-weight ratio for its density.
Finish Recommendations
Takes all standard finishes well. A clear polyurethane or lacquer is recommended to preserve the pale color, though it can be stained to mimic more expensive species like Cherry.
Identification Confidence
Medium-High; identified based on the pale, fine-textured grain, the reddish-brown cambium layer visible under the bark, and the characteristic appearance of a split Birch-family sapling branch.
