Assessment of Stand Structure Characteristics in Forest Compartments Containing Cinnamomum Balansae in Ta Dung National Park, Dak Nong Province, Viet Nam

Understanding forest structure is essential for sustainable forest management, particularly in the context of climate change and increasing anthropogenic pressures.This study aims to analyze the stand structure and biodiversity characteristics of forest communities with the presence of Cinnamomum balansaein Ta Dung National Park, Vietnam.A total of 50 sampling plots (900 m each, 30 30 m) were surveyed, and data were analyzed using RStudio 4.4.0.Results indicate that Cinnamomum balansaeis among the 10 species with the highest Importance Value Index (IVI%), reflecting its significant ecological role in the studied forest stand.Biodiversity indices (Margalef, Shannon-Wiener, Simpson) revealed a highly stable community structure, with Simpson's index (D = 0.98) indicating no single species dominance.Diameter distribution exhibited a reverse Jshaped curve, with small-diameter trees (6-10 cm DBH) dominating, characteristic of an uneven-aged forest with active natural regeneration.Similarly, height distribution analysis showed that medium-height trees (8-16 m) accounted for the largest proportion, suggesting that the forest is in a regeneration and recovery phase.These findings provide crucial scientific insights for sustainable forest management and biodiversity conservation, especially in developing climate-resilient forest policies.Future research should focus on the role of large trees in carbon sequestration, the impact of climate change on forest dynamics, and the application of remote sensing technologies in long-term forest monitoring.
