Study Notes

Measuring Tree Height

Tree height is defined as the vertical distance from the base of the tree to the top of the tree, including the crown.

Methods of Measuring Tree Height

The shadow method is used to measure the height of a standing tree by comparing the length of the tree's shadow to the length of a measuring stick's shadow.

Measuring Felled Trees

The total height of a felled tree is measured from the base of the tree (where the trunk meets the ground) to the top of the tree.

Crown and Bole Height

The base of the crown refers to the point where the main branches emerge from the trunk of the tree.
Bole height refers to the height of the tree trunk from the ground to the base of the crown.
