Forests are one of the most significant reservoirs of carbon. Various global processes and anthropogenic changes are influencing the process of carbon sequestration leading to interruptions in the carbon flux. Under elevated CO2 conditions a possibility of decomposition occurring more than net primary production leading to a loss of carbon is predicted in the forest regions of India.
Forest ecosystems play a crucial role in global carbon cycling acting as a sink and a source. Forests form an active carbon pool that accounts for 60 per cent of carbon storage in the earth’s land surface. Therefore, dynamics of carbon in forest vegetation and soils are significant in terms of global climate change policy framework. The rate of carbon absorption is greatest in the earliest stages of growth and regeneration, and declines as forests mature. Tropical forests, both moist...
