Estimation of soil carbon stocks in Pabitora Sanctuary and Manas National Park in Assam

North East India known for its rich flora and fauna, is covered by the mighty Brahmaputra-Barak river systems and their tributaries and comprises hilly terrain interspersed with valleys and plains. A field study was done to layout the soil carbon stock of Pabitora Wildlife Sanctuary and Manas National Park in Assam. Maximum average carbon stock in both was estimated in the upper layer of the soil sample, while least carbon stock was obtained at deepest layer (20-30 cm). The average carbon stock of the Manas National Park was higher than that of Pabitora Wildlife Sanctuary.
