10 Carbon Stocks from Peat Swamp Forest and Oil Palm Plantation …

fallowed. The secondary forest formed on this site was cleared in 2006 via slash and
burn. Before the oil palm plantation was established in 2008, the land was utilized
for rice and vegetable crops for 2 years.
Field Sampling
We determined the composition, structure, and ecosystem carbon stocks following
methods outlined by Kauffman et al. In the forest sites, six 10 m fixed-radius
(0.0314 ha) plots were established 50 m apart along a 250 m transect as depicted
in Fig. 10.2. Due to area limitation in the plantations, three 10 m fixed-radius plots
were established 20 m apart along a 40 m transect as shown in Fig. 10.3. In addition,
palm height and density were measured in a square plot (50 m × 50 m) established
in each plantation site.
