Assessing Sustainable Development of Carbon Stock and Melaleuca Forest Growth in U Minh Thuong National Park after Big Fires Vietnam

Research conducted in U Minh Thuong National Park to assess carbon storage from fires and water on forest growth and regeneration. In 2003 after forest fire, measures were implemented to promote forest regeneration, afforestation, and rainwater storage, aim to prevent future forest fires. Investigating established in 2023 on the thicknesses of (20–40 cm), (40–60 cm), (60–80 cm) of the 500 m2 per plot, with 5 replications, measuring growth and analyzing peat chemistry. Contents include: Assessing changes in peat and carbon reserves Melaleuca forests before and after forest fires; analysis of peat and water chemical properties during seasonal floods, assessing Melaleuca growth, and the relationship between soil chemistry and growth due to higher water levels 20 years after forest fire. The results show a large volume of peat and carbon reserves, accumulated over thousands of years, destroyed by forest fires; lost in large quantities due to frequent flooding, leading to organic matter decomposition. Melaleuca grows slowly and death ratio increases after 20 years. Study also determined soil and water chemistry by seasonal flood; relationship between peat chemical indicators and Melaleuca growth on peat thickness. Results assessed the total peat volume and carbon stocks accumulated over thousands of years of Melaleuca Forest history, the effects of forest fires and water management on growth and chemical relationships, particularly after above-normal water levels were observed for 20 years. Results are research changes in peat.
