Carbon sequestration estimation at forest of UiTM Sabah branch / Nur Syahfekah Awang

UiTM Sabah Branch has undergo several development including buildings and other infrastructures such as electricity substations, tanks, roads and many more. This development needs the deforestation activities. Deforestation activities caused the carbon dioxide to be saturated at the atmosphere since the quantity of trees left to sink the carbon is limited. Excessive increasing of carbon dioxide at the atmosphere could bring negative impact to the organizations, health, industries, economy and also the ecology. The purpose of this study is to estimate the amount of carbon stock of the trees as well as to study the relationship between the diameter at breast height (DBH) of the trees, elevation and soil pH with the carbon stock of the trees. This study includes five stations covering the area of 13,500 m2 and the findings data from this study was analyzed. The carbon stock of the trees is estimated by using allometric equation by Brown (1997) and was multiply by 0.46 as it is the conversion of carbon content in a tree. The relationship between the DBH of the trees, elevation and soil pH with the carbon stock of trees is determined by using the Pearson’s correlation coefficient. The result showed that the estimation of total carbon stock of the trees at UiTM Sabah Branch is 10.76 kg/m2. This estimation of carbon stock of the trees is far higher compared to the other studies conducted. Thus, indicates that the carbon stock of forest at UiTM Sabah Branch is in a good level. The carbon stock of the trees is increasing as the DBH of the trees increase. The carbon stock of the trees is also increase as the elevation increase. In contrast, soil pH and the carbon stock of the trees showed have weak negative correlation.
