Above ground biomass and carbon stock in 1 Ha Plot Of Gunung Basor forest reserve

Forest ecosystem said to play a major role in global carbon cycle. The forest biomass estimation is vital and act as important indicator in observing and estimating the changes of carbon cycle in forest ecosystem. A study was conducted in Gunung Basor Forest Reserve, Kelantan to estimate the value of above ground biomass and carbon stock. In this study, 1 ha plot was established in Gunung Basor Forest Reserve. A forest inventory data using a nondestructive method was done to measure the diameter breast height of selected trees. Total 137 trees with diameter breast height of 5 cm and above was identified and measured. Most of the trees found fell into DBH range of class 1 which is between 5 cm and 15 cm with total 77 trees. However, the highest value of above ground biomass, 124.34 t/ha was contributing by the trees with DBH 65 cm and above. Total value for above ground biomass in Gunung Basor Forest Reserve was 163.72 t/ha. The carbon stock values was 50% from the above ground biomass value which was 81.86 t/ha. Overall, from this study indicate that the selective management system is important in conserving the biomass in forest ecosystem
