Agricultural and Forest Meteorology, 282, 107869.https://repoemc.ukm.my/handle/123456789/704Wetlands 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.Net ecosystem CH4 exchangeEddy covariance techniqueGroundwater levelUndrained peat swamp forestRelatively disturbed peat swamp forestOil palm plantationJournal
