where V is the volume (in m3), h the height measured with laser
beam (BOSCH DLE 70 Professional model), and Ab, Am, and At are
the areas at base, middle and top respectively. Specific gravity (G)
of the wood was estimated taking the stem cores, by boring 7.5cm
deep with mechanized corer. This was converted into stem biomass
(BS) as per the expression BS = GV. The stem biomass of individual
tree was finally multiplied by the number of individuals of each
species in 15 selected plots in both western and central Indian
Sundarbans.
