The Multi-Stem DBH Calculator enables input of DBH values for trees with multiple stems, and calculates the overall DBH of the tree (The square root of the sum of each stem squared).
To add a multi-stem DBH, click the multiple stems radio button. The DBH field will grey out and the calculator will appear. Enter as many DBH values as necessary and the DBH will automatically calculate as you do so.
Note: You can click the Toggle Multi-DBH Calc button to hide the calculator while you aren’t updating values.
