forest sites in Tanjung Puting, Indonesia
consisting of residual wood from the forests contributed more than half (55%) to the
total aboveground carbon. The dead trees were an insignificant C pool, accounting for
only 3 and 1% of the total aboveground biomass in the primary forests and secondary
forests, respectively. There were no standing dead trees in the oil palm plantation
sites. The dead frond piles C stocks were found in the oil palm plantations but this
C pool is assumed to be insignificant or may be underestimated.
In forests, mean carbon concentrations of litter and understory were 48.43 ±
0.46% and 45.02 ± 0.68%, respectively. Litter and understory C stocks were 4 Mg
C/ha in forest sites and contributed 2% to the total aboveground C stocks. There
was less understory and litter in the oil palm plantations because herbicides were
regularly applied.
