Azadirachta indica 15 The main objective of a TOF inventory is to estimate the growing stock, which is essential for sound management, planning and policy formulation.

An example of a volume table for some species is given below: Both the height and the diameter are recorded in a table. V/D2H = a + bD2H + c/D2H 2.116 Volume figures are in m3.
