Aboveground biomass and carbon stock of necromass in 200m2 at Gunung Basor Forest Reserve

Carbon stock of dead wood or necromass representss the quantity of carbon that in the pool of tree in the tropical forest. In this study were to calculate and evaluate the value of necromass of the the highland forest. There are no previous studies have been carried out to estimate the aboveground biomass of necromass in Kelantan. Therefore, this study was carried out to estimate the carbon stocks of necromass of tropical forest. Necromass and the carbon stock were measured in the two sampling plot of 200m2 in Gunung Basor, Jeli, Kelantan. The total necromass recorded within the study area was 7624.2 t/ha and the carbon stock was 3812.1 t/ha and it was estimated from 11 different classes. Out of 802 necromass samples, the highest value of carbon stock (1849.8 t/ha) was represented by 1% of fallen dead tree with dbh more than 50 cm. Another about 10% (n=402) of necromass contributed the second largest pool of carbon stock (370.9 t/ha). Meanwhile, the lowest necromass that contributed in the study area was below than (1%) (n=10) represented (82.21 t/ha) of carbon stock in the study area. Study area had significantly had a high value of necromass because it due to slow rate of decomposition of necromass stock of different necromass or species and suggested for the flux of carbon dioxide by the virtue to decomposition process that may contribute to 30% to 40% of carbon dioxide in the future. This study, it’s important in providing data about carbon storage of tropical forest in Kelantan to sustain the forest management, especially in Kelantan.
