The evaluate carbon stock in tree biomass: Case study in Bann Huai Lan forest community, Lomsak Distric, Phetchabun Province

Abstract

This study was carried out at Bann Huai Lan forest community, Lomsak District, Phetchabun Province. The main objectives of this research were to assess the characteristic of forest community and carbon accumulated in aboveground biomass of plants. The information will support the database of the local scale of carbon sink. Methodology for study carbon accumulation base on ecological quantitative method, 12 diameter of circular plot was set up for invented tree species and measuring a diameter at breath height (dbh). The assessment of plant communities were density, number of species and important value index, Then carbon accumulation was measure, dbh and height were calculated to aboveground biomass by using allometry equation. Organic carbon in tree biomass was calculated by using Tsutsumi’s constant. Forest community was a mixed deciduous mixed with dry dipterocarp forest. The most dominant trees were Pterocarpus macrocarpus Kurz, Lannea coromandelca (Houtt.) Merr, Shorea siamensis Miq., Catunaregan spathulifolia Tirveng., Xylia xylocarpa (Roxb.) W. Theob. var. Kerrii (Craib & Hutch.) I.C. Nielsen and Dalbergia cana Graham. ex Kurz. Carbon storage in above ground biomass was 80.76 tonne per hectare. We concluded that Bann Huai lan forest community have a highest of carbon accumulation in their biomass. This showed that natural forest around this community have a high potentially as a sink of carbon at a local scale.
