CO2 and CH4 automatic chamber measurenments

Drainage shifts peatlands from acting as a net C sink to a net C source. Despite that rewetting may potentially enhance CH4 emissions, it may also mitigate climate change by greatly reducing CO2 emissions. The speed at which the C sink function is achieved depends on the transition process, including the recolonization of typical vegetation significantly impacting C emissions. This study presents the results of five years of automatic chamber (AC) CH4 and CO2 measurements conducted in a rewetted fen in northeast Germany. Four ACs were placed along a spatial gradient from the shore to the center of a shallow lake after rewetting, followed by cattail colonization. Besides increased CO2 uptake, an intermediate phase with a strongly increased climatic effect due to wave-like increases-decreases in CH4 emissions occurred. It is therefore essential to take a close look at the transition phases to accurately assess climate impact of rewetting over time.
