The document defines various height measurements for trees, including total height, bole height, commercial bole height, standard timber bole height, stump height, crown length, and crown height. It outlines the objectives of measuring tree height, such as determining tree volume, site productivity, and quality. Additionally, it explains the concept of stumpage value as the worth of a standing tree before it is felled.

3. Height Measurement of Trees
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.

4. 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

6. Different Heights of Tree
Measurement
 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.
 Commercial Bole Height: If the height of bole that is
usually fit for utilization as timber called commercial
bole height
 Height of Standard Timber Bole : Height of the
standard timber boleisfrom the ground level to
diameter over bark 20cm.

7.  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

8. 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
