This study investigates the biomass of Melaleuca cajuputi tree at the Tra Su Melaleuca Forest Landscape Protection Area, located in An Giang province, Vietnam. Tra Su Forest is a managed territory under the An Giang Forest Protection
Department. Established as a landscape protection area since 2005, the area has been designated for sustainable development, ecological preservation, educational endeavors, and nature conservation. By quantifying individual tree volumes and the overall population’s productivity, this study calculates the volume and produc￾tion of Melaleuca tree and identifies the sylviculture characteristics within the Melaleuca population of the forest. Methodologies used include the establishment of standard plots for measurement, analysis of tree biomass through field and laboratory techniques, and statistical processing to build correlation equations between various factors. The findings highlight the statistical characteristics of the surveyed area, providing correlations between tree diameters, heights, and their corresponding volumes. Equations derived from these correlations point out the estimation of individual tree volumes which are crucial for forest management and productivity assessment. The study reveals distinct biomass structures within differ￾ent age groups, emphasizing the significance of forest age in biomass accumulation, distribution, and shaping the ecosystem’s sustainability. The results of this study serve as a foundational resource for forestry management, ecosystem preservation, and decision-making reference for sustainable resource utilization within the Tra Su Forest.
