Measuring Tree Volume and Scales

The video tutorial discusses various methods of measuring tree volume in forestry, focusing on board footage for sawtimber-sized trees. It explains how to estimate the board footage of a tree by considering its diameter and merchantable height, using volume tables and tree scale sticks. The tutorial also covers different scales for volume estimation, such as the Doyle scale, and addresses the concept of taper in trees.
