Owing to the huge soil carbon stock and high groundwater level (GWL), tropical
peatlands potentially represent a significant source of methane (CH4) to the
atmosphere. However, a few studies of CH4 flux by the soil chamber technique
have reported that annual CH4 emissions from tropical peat swamp forest were
very low as compared to mid- and high-latitude peatlands. Recently, it has been
reported that some tree species growing in peat swamp forest emit CH4 from
their stems. It is impossible to continuously measure ecosystem-scale CH4 flux
including both soil and plant-mediated CH4 emissions by the chamber technique.
Thus, we have measured net ecosystem CH4 exchange (FCH4) above a tropical
peat swamp forest in Sarawak, Malaysia using the eddy covariance technique
from February 2014 to July 2015 (18 months).
