Abstract

This study determined the potential of tree plantations to sequester atmospheric carbon by measuring the amount of carbon stored in its biomass. The study involved a Dipterocarp and large leaf Mahogany stands located in Mt. Makiling Forest Reserve (MFR), Philippines. The carbon pools investigated included: above-ground biomass (tress, understorey/herbaceous vegetation), ground-biomass (litter and coarse woody debris), and below-ground biomass (roots and soil). Results showed that Mahogany stand has a total biomass of 605.25 t haˉ¹ while the Dipterocarp stand has 563.93 t haˉ¹. However, in terms of carbon content in its biomass. Mahogany has a lower value of 542.05 t C haˉ¹ than the value of 639.81 t C haˉ¹ for Dipterocarp stand.

Estimation of biomass density to carbon accumulation per sink for both Mahogany and Dipterocarp stand showed the following results: above-ground (246.63 t C haˉ¹ and 248.08 t C haˉ¹; ground biomass (20.02 t C haˉ¹ and 20.46 t C haˉ¹); and below-ground biomass (275.40 t C haˉ¹ and 371.27 t C haˉ¹). Ranking the carbon deposits per sink, below-ground biomass has the highest carbon accumulation primarily due to its soil component.
