A dynamic growth model (CO2FIX) was used for estimating the carbon sequestration potential of sal ( Shorea Robusta Gaertn. f.), Eucalyptus ( Eucalyptus Tereticornis Sm.), poplar ( Populus Deltoides Marsh), and teak ( Tectona Grandis Linn. f.) forests in India. The results indicate that long-term total carbon storage ranges from 101 to 156 Mg C ha −1 , with the largest carbon stock in the living biomass of long rotation sal forests (82 Mg C ha −1 ). The net annual carbon sequestration rates were achieved for fast growing short rotation poplar (8 Mg C ha −1 yr −1 ) and Eucalyptus (6 Mg C ha −1 yr −1 ) plantations followed by moderate growing teak forests (2 Mg C ha −1 yr −1 ) and slow growing long rotation sal forests (1 Mg C ha −1 yr −1 ). Due to fast growth rate and adaptability to a range of environments, short rotation plantations, in addition to carbon storage rapidly produce biomass for energy and contribute to reduced greenhouse gas emissions. We also used the model to evaluate the effect of changing rotation length and thinning regime on carbon stocks of forest ecosystem (trees + soil) and wood products, respectively for sal and teak forests. The carbon stock in soil and products was less sensitive than carbon stock of trees to the change in rotation length. Extending rotation length from the recommended 120 to 150 years increased the average carbon stock of forest ecosystem (trees + soil) by 12%. The net primary productivity was highest (3.7 Mg ha −1 yr −1 ) when a 60-...
