Carbon Storage in Tree at Nature Trail in The Initiative of Her Majesty Queen Sirikit Nakhon-Sawan Province

Abstract

Increase in greenhouse gases especially carbon dioxide severely affects the global warming situation. Carbon sequestration is therefore a method used by many sectors to promote climate mitigation activities in order to provide information for preparing greenhouse gas accounting. Nature trail in the initiative of Her Majesty Queen Sirikit Nakhon-Sawan province is a deciduous forest area and located near community areas and agricultural areas with no information on carbon storage. The objective of this study is to survey the plant species in the nature study route area in order to quantify the amount of biomass of trees and carbon storage in the project area. In total of 3.68 hectare, 3 sample plots, representing 13% of the total area, were randomly selected based on the density of the number of trees: high, medium, and low, with plot sizes of 0.16 hectare. The findings revealed a total of 409 trees, comprising 48 species from 24 families in the study area. The most commonly found tree species was Dipterocarpus obtusifolius Teijsm. ex Miq., with a species importance value index of 55.18, followed by Pterocarpus macrocarpus Kurz, Lannea coromandelica (Houtt.) Merr., Bombax anceps Pierre var. Anceps and Terminalia corticosa Pierre ex Laness. with values of 22.49, 21.48, 19.77 and 11.93 respectively. The average biomass of 173.88 tons/ha, total biomass of 639.86 tons, The average carbon storage of 81.71 tons/ha and total carbon storage of 300.69 tons was obtained. The results of this study will be used as resource database for the operation of the Protected Area Regional Office 12 (Nakhon-Sawan) in the Department of National Parks, Wildlife and Plant Conservation.
