Wetlands in Southeast Asia are thought to be one of the greatest sources of
methane (CH4) to the atmosphere. Tropical peatlands are typical in Southeast
Asia, and store an enormous amount of soil organic carbon. However, chamber
studies of soil CH4 flux have reported that CH4 emissions from tropical
peatlands in Southeast Asia are almost negligible. Recently, it was reported
that some tree species growing in peat swamp forests emit considerable CH4
from their stems. Thus, ecosystem-scale flux measurement is essential to
quantify the CH4 balance of tropical peat ecosystems. In this 3-year study
(February 2014 to January 2017), using the eddy covariance technique, we
measured the net ecosystem exchange of CH4 (FCH4) above three different
tropical peat ecosystems in Sarawak, Malaysia.
