Paper Title
Carbon Sequestration Potentials of Some Common Urban Tropical Tree Species for Climate Change Mitigation in Chiang Mai Municipality
Abstract
An assessment of carbon sequestration potentials of some common urban tropical tree species in Chiang Mai
Municipality was carried out through biomass estimation and carbon conversion. The objectives of this research were to
measure carbon sequestrated by urban tropical tree species in Chiang Mai Municipality and to produce a carbon
sequestration map for urban tropical tree species in Chiang Mai Municipality. The assessment was based on an inventory of
some common urban tropical tree species havingstems “≥ 5cm (DBH).” Some selected common urban tropical trees species
were identified to the species level, and their diameters at breast height (DBH) were measured, and heights from the
measured DBH in the field were calculated. The above ground biomass was calculated through the DBHs and the heights
using existing allometric equations, and later the biomass was converted to carbon in tons/hectare. The results revealedthat
“7,431,” urban tropical tree species were found and sequestered “301.698tons/hectare,” of carbon.Ficus religiosa tree
species had the highest carbon content sequestered about “30.262 tons/hectare,” follow by Terminalia catappa tree speciesat
about “27.439 tons/hectare,” and the least carbon sequestered content was Plumeria rubria tree species at “16.894
tons/hectare.” The dominant tree species Mangifera indica at “1,400,” trees followed by Plumeria rubia at “1,092 tree,” and
the least among them was Delonix regiaat “100 trees.”The tree with the largest DBH was Ficus religiosa at “300 cm,”
followed by Terminalia catappa at “182 cm,” and the least was Plumeria rubriaat “34 cm,”. The tallest tree species was Ficus
regliosaat “25 m,” follow by Terminalia catappa at “23.4 m,” and the shortest was Plumeria rubria at “16 m.”The resultsalso
revealed the average DBH at “5.34 cm,” and the average high was “28 m.”
