Community Structure, Diversity and Carbon Sequestration in Biomass of Community Forests; Ban Hinlad and Ban Hinlad-Kao Noi, Wang Nang Subdistrict, Mueang District, Maha Sarakham Province

Abstract

The community structure, diversity and carbon sequestration in biomass from two different
community forests in Ban Hinlad and Ban Hinlad-Kao Noi, The study sites 20 m × 20 m were replication
15 and 10 plots, respectively. The collected data included species, number, height and diameter at breast
height (DBH). The results showed that 43 and 39 tree species. Tree density were 184 and 183 trees per
rai. The dominant trees from importance value index (IVI) of Ban Hinlad community forest were Sindora
siamensis Teijsm. ex Miq., Xylia xylocarpa (Roxb.) Jaub.), Canarium sabulatum Guillaumin, Shorea

obtusa Wall. ex Blume.) and Catunaregam tomentosa (Blume ex DC.) Triveng, respectively. And
the dominant trees of Ban Hinlad-Kaonoi community forest were Dipterocarpus obtusifolius Teijsm. ex Miq.,
Xylia xylocarpa (Roxb.) Jaub., Canarium sabulatum Guillaumin, Shorea obtusa Wall. ex Blume. and Grewia
elatostemoides Coll. et Hemsl., respectively. DBH distribution pattern was L-shape and the most common
size class was 4.5 to 10 cm. Carbon content of these forests were 6.25 and 7.81 tons carbon per rai.
Carbon stocks were equal 237.58 and 195.22 tons carbon. Total carbon sequestration was equal 871.13,
and 715.81 tons carbon dioxide equivalent. The estimation of carbon dioxide capture over the next 20
years will storage increase 729.60 and 480.00 tons carbon dioxide equivalent
