Definition

Total height of the tree is the straight line distance from the tip of the leading shoot (or from the highest point of the crown where there is no leader) to the ground level, usually measured on slopes from the uphill side of the tree.

Objective

• To find out tree volume
• To read volume tables, form factor table, yield tables, etc
• To find out productive capacity of the site
• To find out the site quality of a locality

Different Heights of Tree Measurement

1. Bole Height: The distance between ground level and Crown Point is called bole height, Crown Point is theposition of the first crown forming living ordead branch.
2. Commercial Bole Height: If the height of bole that is usually fit for utilization as timber called commercial bole height
3. Height of Standard Timber Bole : Height of the standard timber boleisfrom the ground level to diameter over bark 20cm.

• Stump height: The height of the top of the stump above ground which gives the tree stem is lift attached to the ground after felling ( 20 to 30 cm ), called stump height. Value of standing tree before felling is called stumpage value.
• Crown length: The vertical measurement of the crown of the tree from the tip to the point half way between the lower green branches forming green crown all round and the lowest green branch on the bole, called crown length
• Crown height: The height of the crown as a measured vertically from the ground level to the point half way between the lowest green branches forming green crown all round, called crown height
