Boreal peatlands represent an important store of carbon and wildfire can have a significant impact on carbon exchange. We assessed the impact of fire on methane (CH₄) emissions using both a field and laboratory study. We found that fire switched the typical understanding of peatland CH₄ emissions, burned sites having significantly reduced emissions (likely due to reduction in organic matter for CH₄ production) and no relationship with water table, unlike at the unburned site.
