Forests are natural carbon sink and play an important role in sequestrating the atmospheric carbon into biomass and soil. Estimation of total biomass and soil carbon sequestered in any forest is very important as it gives ecological and economic benefits to the local people. Schima-Castanopsis forests were selected for the study in Palpa district with the objectives of quantifying the total carbon sequestration, and evaluation of aspect and elevation on carbon storage. Stratified random sampling method was used for assessing biomass. Biomass was calculated using different allometric models. The biomass carbon content was taken 43% of the dry biomass. Soil samples were taken from soil profile up to 1 m depth for deep soils and up to bedrock for shallow soils at an interval of 20 cm. Walkey and Black method were applied for measuring soil organic carbon. Total biomass carbon in Schima-Castanopsis forest was found higher in northern aspect but soil carbon sequestration was higher in western aspect. Likewise, total carbon sequestration in western aspect was found 1.17 times higher compared to northern aspect at an elevation range 1100-1200m. Similarly, total carbon sequestration was found 1.13 times higher at an elevation range 1350-1500 m than 1100-1200 m.
