Tropical forests play a crucial role in capturing atmospheric carbon emissions. This study investigates the differences in biomass carbon across land-use categories and determines the key determinants of carbon storage in Dibru-Saikhowa National Park (DSNP). The park is situated in the upper flat alluvial floodplain of the Brahmaputra River in Assam, India, and it is a part of the Indo-Burma global biodiversity hotspot. A total of 60 species belonging to 47 genera and 31 families were reported. The significant difference was observed in mean carbon stock among the different land‑use systems of DSNP, following this order: river sand (5.75) <agricultural land (17.07 Mg/ha) <grassland (26.92 Mg/ ha) <deciduous forests (71.04 Mg/ha) <semi-evergreen forests (77.59 Mg/ha) <plantation (130.36 Mg/ha). Carbon stocks reveal strong correlations with forest attributes such as tree density and species richness. The findings of the study show that DSNP exhibits significant species diversity and carbon stocks, indicating its potential for successful carbon storage and biodiversity conservation. These findings provide crucial insights for SDG 13: Climate Action, REDD & REDD+ programs and national forest inventories, emphasizing the importance of maintaining key species for carbon storage and advocating for long-term monitoring of carbon stocks.
