Value of carbon stock in aboveground biomass of peat swamp forest, nakhon si thammarat province

Abstract

This study was undertaken by using 10x10 m2 sampling plots chosen by stratified random sampling from 3 areas, 50 plots for each area. Height and diameter of all trees with girth breast height (GBH) stem > 15 cm were measured. Aboveground biomass was estimated by allometric equation and the carbon stock was calculated by multiplying biomass value with conversion factor of 0.47. Result founded 4 tree species in 4 families. The Melaleuca cajuputi Powell had quite high density of 2,091.31 tree/ha and other species found in some areas are Mitragyna brunonis Craib., Barringtonia coccinea Kostel., and Symplocos ferruginea Roxb, with the density of 4.67, 2.67 and 2.00 tree/ha, respectively. Amount of aboveground carbon stock was 26.27 tonne C/ha. Mostly, stem had higher carbon stock than branch and leaf at 19.92, 4.94 and 1.62 tonne C/ha, respectively. Average value of biomass carbon was 86.77 bath/ha.
