Objective: The study was conducted in U Minh Thuong National Park to address forest regeneration.Theoretical framework: After a major forest fire in Vietnam, various measures were taken to promote forest regeneration, including afforestation, silvicultural solutions, and hydrological techniques such as rainwater storage to maintain humidity and prevent future fires.Method: Using a handheld drill, a total of 15 plots were established in the same growth forest area to conduct a survey on peat thickness across three levels. Each sampling site was numbered as UTM1, UTM2, and UTM3, and one kilogram of sample was collected from each site. These samples were then transported to the laboratory of the Southern Institute of Forestry Science for analysis.Results and conclusion: There was a relationship between peat chemical indicators and the evolution of the Melaleuca Forest. Peat thickness and flooding regime significantly influenced the growth of the Melaleuca Forest, while another study identified a relationship between peat chemical indicators and forest growth. The chemical composition of peat water changed significantly due to the rainy and dry seasons, with nutrient content and pH affecting forest growth. Peat thickness and flooding regime were essential in regulating forest growth. These studies highlight the importance of considering multiple factors, such as peat thickness and chemical properties, when developing effective forest restoration strategies.Implications of the research: By understanding the relationship between peat thickness, chemical properties, and forest growth, forest managers can develop targeted strategies to promote regeneration while minimizing negative impacts on biodiversity.
