| Abstract | Doi Ngaem plant genetic protection area in Mae Fah Luang University is a mixed deciduous bamboo forest over an estimated land area of approximately 1,115 rai. In the past, this forest area was degraded due to farming. The forest area has been subsequently restored naturally, with the University providing plant genetic protection and conservation of biodiversity. This study aimed to investigate the plant community structure, species diversity, estimation of biomass, and carbon stock value evaluation. Ten temporary sample plots of size 20 meters x 50 meters each, were constructed and data were collected, which included a survey of the tree and bamboo species. The data were used to determine the importance value index (IVI) of plants, diversity index, above ground biomass, carbon stock and its valuation using allometric equations, and the carbon credit trading in 2022. The forest had 55 species in 45 genera and 26 families, with a density of 128.96 tree/rai. The species with the most significant IVI were Wrightia pubescens, Vitex canescens, and Gigantochloa hosseusii of 29.23, 28.48, and 27.64, respectively. The Shannon-Wiener index (H') was 3.12, with a total biomass of 93.02 t/ha, and total carbon stock of 48.31 tC/ha (carbon credit), which was a relatively high value. This accounted for a traded value in the EU carbon market (EUA) of 156,542.18 baht and in the California market (CCA) of 52,396.16 baht, accounting for a total carbon dioxide absorption of 177.30 tCO2e/ha. The results of this study can be used to study the various approaches to manage the current climate change issues related to forest ecosystem restoration, and to study carbon stock to assess the traded economic value in the carbon market. This also includes pushing such areas to enter the greenhouse gas emission reduction project under the CDM (Clean Development Mechanism) of Thailand in the future. |
