Abstract
Methane is an important greenhouse gas. Aerated forest soils are assumed to be an atmospheric methane sink. However, methane emission from small riparian wetlands and/or tree-mediated methane emission have the potential to offset the soil methane sink and may convert the forest from a net sink to a net source. In this paper, I focus on the methane emission from the stem and the ecosystem-scale methane flux in tropical peat swamp forest. These topics are particularly uncertain in forest methane dynamics. The soil water condition was an important controlling factor of methane fluxes in forests in all cases. Finally, how integrated analysis using an international database of ground-based observation data can be used for understanding global methane dynamics is discussed.
