Wetlands represent the largest natural source of methane (CH₄), so understanding CH₄ drivers is important for management and climate models. We compared several CH₄ pathways of a remediated subtropical Australian wetland. We found permanently inundated sites emitted more CH₄ than seasonally inundated sites and that the soil properties of each site corresponded to CH₄ emissions. This suggests that selective wetland remediation of favourable soil types may help to mitigate unwanted CH₄ emissions.
