Estimation of aboveground carbon stock in service area of Ubon Ratchathani Zoo, Ubon Ratchathani province, Northeastern Thailand

Abstract

Results found a total of 200 trees of 22 species which belongs to from 16 families. The most common family was Dipterocarpaceae with 129 trees, including Shorea roxburghii G. Don (40% of total trees), Dipterocarpus alatus Roxb. (17% of total trees), and Dipterocarpus intricatus Dyer (7% of total trees). The total aboveground biomass and total carbon storage for all trees were 52,337.3 kg (200.1 kg rai -1) and 2 4,598 .5 kg (.2 4 6 ton), respectively. A total of carbon dioxide absorption for the study site was 85.4 t-CO2 or 60.6 t-CO2 ha-1 (9.7 t-CO2 rai-1). It is provided an important data for climate mitigation policy i.e., carbon credit policy and carbon credit trading in the future. This study is firstly estimated of carbon storage by trees growing in the service area of National Zoo in Northeastern Thailand.
