Biomass and soil carbon stocks in relation to the structure and composition of Chir Pine dominated forests in the lesser Himalayan foothills of Kashmir

Abstract

Quantification of carbon stocks is critical to evaluate the potential of an ecosystem to mitigate the impact of global climate change in the REDD + scenario. Present research project was designed to gauge the sequestered carbon in Chir Pine (Pinus roxburghii) dominated forests in the foothills of the western Himalayan region of Kashmir which constitute a significant regional carbon pool. The study outcomes revealed an average carbon stock value of 94.3 Mg/ha from which 68 Mg/ha was shared by soil organic carbon (SOC); whereas average biomass carbon share was 26.3 Mg/ha. P. roxburghii was the most noteworthy species containing an average carbon stock value of 5.93 Mg/ha followed by Quercus incana (3.59 Mg/ha) and Olea cuspidata (2.26 Mg/ha). Average forest biomass was chronicled as 52.5 Mg/ha from which tree biomass was 49.34 Mg/ha. Shrub and herb biomass contributed 1.95 and 0.53 Mg/ha correspondingly whereas the Leaf litter and deadwood necromass produced an average of 0.67 Mg/ha. Ordination analysis revealed that the forest carbon stocks were significantly influenced by the species composition, structural attributes as well as anthropogenic disturbances. Current study has resulted in generating a standard baseline dataset of the regional carbon stocks with diverse implications for sustainable carbon management in REDD + perspective.
