Volume of Standing Trees Using the Doyle Log Scale
Approximate the board foot volume of a tree using the Doyle log scale.
Board foot value results are for Girard form class 78, the most commonly used class.
Instead of using "merchantable height" in 16-foot logs this calculator uses the merchantable height of the tree from a one-foot stump height to where main stem diameter equals a specified limit. The diameter measured @ breast height (4.5 feet) in inches.
Doyle Log Rule for Standing Tree
- enter the merchantable height of a tree in feet
- tree diameter measured at breast height in inches
- board foot volume of the tree as reported in Girard form class 78
