Are Sacred Groves of Kathmandu Valley Efficient in Sequestering Carbon?

Abstract

Ability of plant to fix atmospheric carbon dioxide and store it in biomass is contributing to global carbon cycle. Sacred groves, one of the regimes for forest management, play role in regulating climate by acting as sinks for carbon. Aiming to assess sequestrated carbon in tree the study was conducted in two sacred groves of Kathmandu valley, Nepal. Concentric circular plots of 20 m radius were used for data collection. Allometric equation having height, diameter, and specific gravity of tree was used to determine biomass. The calculated biomass of tree was converted to the carbon stock by using carbon fraction. Tree species of both sacred groves sequestered 15.08 metric tons of carbon. The carbon stock was high in Quercus-Myrsine forest and low in Schima-Pyrus forest.
