Abstract: Abstract The climatic and non-climatic stresses impacted adversely to the functioning and productivity of the forests, resulting in disturbing the existing carbon flow in the atmosphere. Cedrus deodara occurs in pure forest stands throughout the Western Himalayas and has high biomass and soil carbon sequestration potential. The present study aims to provide the contribution of the Cedrus deodara forests under the current stresses for climate mitigation by analysing the three elevation ranges of the Dhanaulti forest division of Garhwal Himalaya, India. The results report that soil organic carbon (SOC) was adversely and bulk density favourably related with elevation. Moreover, SOC as CO2eq also decreased significantly with an increase in soil depths. Biomass carbon for various parts of the plant was also estimated for the three elevations of the Cedrus deodara forests. The trend in total carbon stock (bole, branch, twig, foliage and soil) decreased significantly with an increase in altitude. The carbon stock of Cedrus deodara forests was maximum (545 t ha−1) at upper altitude (2350 m.a.s.l) and minimum (330 t ha−1) at a lower altitude (2050 m.a.s.l). The difference in litter production between the seasons is significant with maximum production in summer followed by rainy and winter seasons. This study provides inputs for greenhouse gas (GHG) estimation for national communication to various platforms. The information on the soil is crucial for understanding about the ecology of the forests assisting prediction of functioning and productivity of forests.
