In a laboratory experiment we examined methane release of plant litter from fresh and brackish water species. In addition, we measured in-situ-methane fluxes in mono-dominant vegetation stands in a coastal fen before and after rewetting. Finally, we determined nitrous oxide exchange in high and low intensity grasslands on shallow histosols. Our results show that flooding with Baltic Sea water would at least in the short-term decrease methane release substantially, independent of vegetation composition. In contrast, flooding with fresh water leads to a vegetation-specific hundredfold increase of methane emissions of about 1 t CH4 ha-1 yr-1 on average. On the grassland sites we detected no significant net nitrous oxide release on either the high or the low intensity grassland. Our examinations highlight the necessity of long-term investigations to assess the effectiveness of peatland rewetting as a climate mitigation measure.}, note = { \url {http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/7290}}, }
