Bamboo bearing fast-growing nature increases its biomass accumulation rate making it a potential species to sequester and store carbon. Carbon stock estimation in bamboo forests can aid in evaluating the carbon sequestration capacity of bamboo species and their role in mitigating CO2 concentration in the atmosphere. Present study was conducted in Arunachal Pradesh to assess the amount of carbon sequestered by Dendrocalamus hamiltonii—a sympodial tropical and Chimonobambusa callosa—a monopodial subtropical bamboo species. Total standing biomass of 247.75 ± 78.84 Mg ha−1 and 46.02 ± 16.50 Mg ha−1 were recorded for D. hamiltonii and C. callosa, respectively. Total carbon stored in the standing crop of D. hamiltonii was 105.34 ± 36.27 Mg ha−1 while in C. callosa the value was 20.02 ± 7.13 Mg ha−1. Higher rate of carbon capture and carbon pool in the growing stock of D. hamiltonii forests in the tropical zone may be attributed to the differences in size of the poles, type of rhizomes, density along with edaphic and climatic conditions. Interestingly, the soil carbon pool was significantly higher in C. callosa forest in the subtropical belt than that of D. hamiltonii forest in the tropical belt with 90.51 ± 12.03 Mg ha−1 and 42.27 ± 4.24 Mg ha−1 carbon, respectively. Soil carbon pool followed a decreasing trend with increasing soil depth. A significant variations of carbon sequestration capacity was observed between the species. In vegetation pool, higher carbon sequestration capacity was recorded in D. hamiltonii forest while in soil pool, the value was higher in C. callosa forest.
