ABSTRACT: The
present study was aimed to assess the growing stock of Timergara forest
subdivision which was a part of Dir lower forest division (Pakistan). The study
area was divided into two different climatic zones (i.e. sub-tropical sub humid and sub-humid temperate zones) on the
basis of altitudinal considerations. A total of 43 sample plots are taken in
the forest area of 8480 hectare with random sampling technique representing
0.5% of the total forest area. Each sample plot size was of one hectare. In
each 100 × 100 m (1 ha plot), number of trees, diameter, age, height,
increment, form factor and volume were measured. An interrelation between the
diameter (independent variable) and all the other dependent variables (volume,
increment and height) were found. At the end, volume tables were made which
suited the local conditions as the ones used before were not suited to the
local conditions.
