Abstract

This study analyzed the vegetation and soil carbon stock in natural forest in Mahabharat hill of Bagmati Province, Pinus roxburghii Nepal. Systematic random sampling method was applied for forest inventory and forest biomass was estimated by using standard allometric models. Soil samples were taken from soil profile up to 60 cm depth at the interval of 20 cm. Total carbon stock in forest was Pinus roxburghii found 193.54 t ha and 226.54 t ha for Aphnai CF and Okhe CF, respectively. Among the carbon pools carbon stock was found in the order of -1 -1 above ground carbon stock > soil organic carbon stock > below ground carbon stock for both CF. The forest carbon stock showed a positive relationship with biomass, tree diameter, and height but no relationship with tree density. The study concluded that forest vegetation and soil can play vital role on carbon sequestration and subsequently mitigating the problem of global warming.
