Fig. 10.7 Total ecosystem C stocks (Mg C/ha) of peat swamp forests (primary and secondary) and
oil palm plantation sites in Tanjung Puting, Indonesia. Vertical bars are standard errors
of the aboveground to belowground C stock was highest in secondary forest site with
an estimated value of 0.48, followed by primary forest (0.19) and oil palm plantation
(0.04). Peat swamp forest conversion resulted in substantial C losses from vegetation
cover change, of 640 Mg CO 2 /ha.
Discussion
Composition and Structure of Forest
Tanjung Harapan as secondary forest clearly shows differences on diameter distribution, basal area, and important value index compared to two other primary forest
sites; Beguruh and Pesalat. It clearly indicates that Tanjung Harapan is at early to
medium stage growth of secondary forest and recovering from human disturbances
in particular encroachment in the past. The secondary forest carbon pool at Tanjung
Harapan site suggests a rapid rate of carbon sequestration when sites are abandoned
and native vegetation is allowed to grow (in the absence of fire and other human
disturbances).
