KEANEKARAGAMAN POHON DAN POLE SERTA POTENSI KARBON TERSIMPAN DI KAWASAN HUTAN SEKUNDER 30 TAHUN DAN PERKEBUNAN KOPI DI TELAGAH, LANGKAT
Abstract: The
diversity of tree,
pole and potential
of carbon stored
in 30 years
secondary forest and
coffee field at Telagah District of Langkat was
investigated from February to June 2012. The
study site was determined by purposive sampling method with total area
40 x 200 meters. The study site is

0.520 and 0.586
for pole. The
potential of carbon
stored in tree
is 146.519 ton/ha, 3.933 ton/ha for pole, and 0.0489 ton/ha for coffee
plantation.
