This research, A Comparison of Carbon Sequestration in Tree Species at Wichienmatu School, Mueang District, Trang Province, aims to study the carbon sequestration capacity of trees within Wichienmatu School. The study involved measuring the height and circumference of nine tree species, with five trees sampled per species. The studied tree species were Coconut Palm (Cocos nucifera), Rough-leaved Fig (Ficus hispida), Eucalyptus (Eucalyptus spp.), Cajeput (Melaleuca cajuputi), Jacaranda (Jacaranda obtusifolia), Dipterocarp (Dipterocarpus alatus), Teak (Tectona grandis), Betel Nut Palm (Areca catechu), and Perfume Flower Tree (Fagraea fragrans). The carbon sequestration of each species was estimated using biomass calculation methods. The results showed that Dipterocarp (Dipterocarpus alatus) had the highest carbon sequestration, exceeding 760.962 kgC. Cajeput (Melaleuca cajuputi) and Eucalyptus (Eucalyptus spp.) followed, with average carbon storage values of approximately 574.446 kgC and 444.788 kgC, respectively. In contrast, Rough-leaved Fig (Ficus hispida) had the lowest carbon sequestration among the studied species.
