Thus, to calculate the annual carbon sequestration, we added the average
annual diameter growth (0.61 cm ) and the average height growth
(15 cm ) to all trees. The above-ground and below-ground biomass
of the trees were calculated using the equations in step. 2. The amount
of tree biomass that converted to the sequestrated carbon was estimated
per year by using the equations in step 3. Finally, the results of this
step (annual carbon sequestration in above-ground and below-ground
biomass) were subtracted from the value in step 3. The result value is
the amount of annual carbon sequestration in each tree.
