Height and Diameter Measurement of Trees

Diameters in these tables are Diameters at Breast Height (DBH) measured over bark, in centimetres. Loose bark and vines should be removed prior to measurement.

A tree's height should be measured to the top of the merchantable bole, recorded in metres. The height of the bole at either point where the bole branches into the crown of the tree, or the point where the bole reaches a minimum diameter of 15 centimetres, whichever is the larger.

Those not familiar with measurement of height and diameter of standing trees should refer to a forestry consultant or suitable textbook.
