Grain Pattern

Coarse, usually straight to irregular grain with prominent growth rings; the photographed rounds show flat-sawn end grain and no distinctive decorative figure.

Color & Appearance

Approximately 2,680 lbf Janka for Coast live oak—Extremely Hard.

Durability & Decay Resistance

Moderately Durable; heartwood has useful decay resistance, but exposed end grain and sapwood can deteriorate and attract insects.

Value & Age

Estimated Market ValueNot an official valuation

As mixed, irregular firewood: roughly $0.05–$0.25 per board foot equivalent; clear kiln-dried lumber would commonly be about $8–$20+ per board foot.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
The wood appears recently cut, likely weeks to months old; the bark and bright end grain show little long-term patina.

Common Uses

Firewood, flooring, furniture, cabinetry, beams, tool handles, and turning stock; these pieces appear primarily intended for firewood or mulch.

Geographic Origin

Coastal California and northern Baja California; related California oaks occur throughout the state.

Workability

Hard and abrasive; it machines reasonably when dry but can tear out, split, and blunt tools. Pre-drilling is recommended; drying may produce checking and movement.

Finish Recommendations

For finished lumber, dry thoroughly, sand progressively, then use oil, shellac, lacquer, or polyurethane; seal end grain to reduce checking.

Notable Features

Heavy, dense wood with conspicuous annual rings and high firewood heat output; tannins may darken iron-contaminated surfaces.
