Estimation of diameter at breast height of Shisham (Dalbergaia sissoo Linn.) from stump measurements
Estimation of diameter at breast height of Shisham (Dalbergaia sissoo Linn.) from stump measurements
Raja Walayat Hussain and S. Hassan Abbas
ABSTRACT
Diameters of shisham trees were measured at 6 inches (15
cm) interval from ground level up to breast height 4.5
feet (1.37 meters). Each set of diameters had a strong
linear correlation with diameter breast height. Separate
straight line regression equations were developed using
sets of diameters of different heights as independent
variables and diameter breast height as dependent
variable. Estimations of diameter breast height were doe
from these equations against diameters ranging from (1
cm to 100 cm) at different height along the stem from
ground level up to 4 feet (1.22 meters).
