Formula

Value = Board Feet x Price per BF | Doyle BF = (D-4)^2 x L / 16

Tree value equals the estimated board foot volume multiplied by the stumpage price per board foot. The Doyle log rule calculates board feet as (DBH minus 4 inches) squared, times the log length in feet, divided by 16.

Worked Examples

Example 1: Red Oak Saw Timber

Problem:A red oak has 20-inch DBH and 32 feet of merchantable height. Stumpage price is $0.55/BF.

Solution:Doyle BF = (20-4)^2 x 32 / 16 = 256 x 32 / 16 = 512 BF\nValue = 512 x $0.55 = $281.60

Result:Doyle: 512 BF, Value: $281.60

Example 2: Black Walnut Veneer

Problem:A black walnut tree has 18-inch DBH and 16 feet of clear log. Price is $2.50/BF.

Solution:Doyle BF = (18-4)^2 x 16 / 16 = 196 BF\nValue = 196 x $2.50 = $490.00

Result:Doyle: 196 BF, Value: $490.00

Frequently Asked Questions

How is tree value calculated?

Tree value is calculated by first estimating the board foot volume using a log rule (Doyle, Scribner, or International), then multiplying by the stumpage price per board foot for that species. The three main factors are tree diameter (DBH), merchantable height (the usable length of the trunk), and species. A board foot is a unit of lumber measuring 1 foot by 1 foot by 1 inch thick. Stumpage prices vary greatly by region, species, quality, and market conditions.

How much is a large oak tree worth?

A large red oak with 20-inch DBH and 32 feet of merchantable height contains roughly 128 board feet (Doyle). At typical stumpage prices of $0.50-0.70 per board foot, this single tree is worth $64-90 standing. A 30-inch DBH red oak with 48 feet of merchantable height might contain 507 board feet, worth $250-350. Exceptional veneer-quality white oak can be worth significantly more. An entire acre of mature oak forest might contain 5,000-15,000 board feet valued at $2,500-10,000.
