Anna O Simalango (101201121). The economic value of carbon stocks above and below ground of standing tree in education forest University of North Sumatera. Supervised by Dr. Agus Purwoko, S.Hut., M.Si. and Siti Latifah, S.Hut., M.Si., Ph.D. This study was conducted to determine carbon stocks, and economic value of carbon stocks above and below ground (roots)of standing tree in education forest University of North Sumatera, Tongkoh, Karo District, North Sumatera. This study was conducted June 2014. The collecting of data is used path method,and the sampling technique used purposive sampling with random start method.
