Therefore, a short-term study from 2022 to 2023 was conducted to examine the carbon sequestration potential of subtropical montane grasslands in Ukhrul, at an elevation 1700–2200 m above sea level. Carbon density in three pools (aboveground biomass, belowground biomass, and soil), net primary production, and soil CO2 efflux were assessed seasonally. The carbon fraction of the biomass was calculated by a 0.45 conversion factor. The grasslands exhibited high belowground carbon density (51.41–73.80%), with root:shoot ratios ranging from 1.06 to 2.82. Soil organic carbon at Phangrei was higher than at Piyangmai, with median values of 88.37 Mg C/ha and 74.36 Mg C/ha, respectively. The net primary production was recorded to be relatively higher in Piyangmai grassland, while soil CO2 efflux was not significantly different between the grassland sites. Greater net ecosystem production at Piyangmai (6.65 Mg C/ha) indicates stronger carbon sink potential relative to Phangrei (3.74 Mg C/ha), though both sites functioned as net carbon sinks. Positive net ecosystem production indicates a high potential of subtropical montane grasslands to sequester carbon. Temperature and precipitation emerged as the primary regulators of soil carbon storage and efflux. The present grasslands, which are important carbon sinks, might become sources if not managed sustainably under changing climatic conditions.
