산림 입목 집계 계산기

Measure representative trees by DBH and height, count similar trees, then use log rules (Doyle, Scribner, or International) to calculate total volume.

A 2-inch range grouping trees by DBH (e.g., all trees 14-16 inches). This standardizes forest inventory data and simplifies calculations.

Typically within 10-15% of actual yield. Factors like tree form, defects, and bucking decisions affect final lumber recovery.
