 Abstract:

This study examines the carbon stock in the soils of natural, disturbed and managed dipterocarps forest types located in and around Berembun (BFR) and Kenaboi Forest Reserves (KFR), Negeri Sembilan, Malaysia. The objective was to empirically establish the effects of forest types and land use on the soil carbon stock with a view to evolving management and policy strategies of preserving the soil carbon stock. Consequently, soil samples were collected in the field down to 1m and analyzed in the laboratory for bulk density and soil organic carbon (SOC). The results of the total soil carbon to 1m depth across plots reveal that the highest value (96.1 ±4.1 t C ha-1) was found in the unlogged forest (plot 5) and the lowest at the degraded forest (plot 10) (44.8 ±3.77 t C ha-1. Although there was no statistically significant difference in the means of SOC and forest land use, however, the mean SOC in logged forest was lower than unlogged forest. The SOC in the rubber plot was higher than the value obtained in the logged twice plotting. Rehabilitating a degraded forest rejuvenates the soil carbon stock as the SOC in the rehabilitated forest was higher than that of the degraded plot. The key finding of the study suggests that the soil holds a substantial amount of organic carbon, which, although not statistically significant, but seems to be influenced by forest type and land use. It is recommended that intact natural forests may be preserved, unsustainable logging activities may be replaced with sustainable logging techniques such as RIL and degraded forests should also be rehabilitated through reforestation to restore the soil carbon stock. In addition, routine silvicultural practices should be sensitive to the vulnerability of the forest soil in order to protect the top soil where a greater percentage of carbon is found.
