Peatland restoration via rewetting aims to recover biological communities and biogeochemical processes typical to pristine peatlands. While rewetting promotes recovery of C accumulation favorable for climate mitigation, it also promotes methane (CH4) emissions. The potential for exceptionally high emissions after rewetting has been measured for Central European peatland sites previously grazed by cattle. We addressed the hypothesis that these exceptionally high CH4 emissions result from the previous land use. We analyzed the effects of cattle dung application to peat soils in a short- (2 weeks), a medium- (1 year) and a long-term (grazing) approach. We measured the CH4 production potentials, determined the numbers of methanogens by mcrA qPCR, and analyzed the methanogen community by mcrA T-RFLP-cloning-sequencing. Dung application significantly increased the CH4 production potential in the short- and the medium-term approach and non-significantly at the cattle-grazed site. The number of methanogens correlated with the CH4 production in the short- and the long-term approach. At all three time horizons, we found a shift in methanogen community due to dung application and a transfer of rumen methanogen sequences (Methanobrevibacter spp.) to the peatland soil that seemed related to increased CH4 production potential. Our findings indicate that cattle grazing of drained peatlands changes their methanogenic microbial community, may introduce rumen-associated methanogens and leads to increased CH4 production. Consequently, rewetting of previously cattle-grazed peatlands has the potential to lead to increased CH4 emissions. Careful consideration of land use history is crucial for successful climate mitigation with peatland rewetting.

Disentangling the effects of methanogen community and environment on peatland greenhouse gas production by a reciprocal transplant experiment
Juottonen, Heli (Wiley-Blackwell, 2020)Northern peatlands consist of a mosaic of peatland types that vary spatially and temporally and differ in their methane (CH4) production. Microbial community composition and environment both potentially control the processes ... -
Effects of habitat restoration on peatland bird communities
Alsila, Terhi; Elo, Merja; Hakkari, Tomi; Kotiaho, Janne S. (Wiley-Blackwell, 2021)Restoration of damaged ecosystems has become an important tool to slow down the biodiversity loss and to maintain ecosystem services. Peatland bird populations have shown a substantial decline during the recent decades in ... -
Integrating Decomposers, Methane-Cycling Microbes and Ecosystem Carbon Fluxes Along a Peatland Successional Gradient in a Land Uplift Region
Juottonen, Heli; Kieman, Mirkka; Fritze, Hannu; Hamberg, Leena; Laine, Anna M.; Merilä, Päivi; Peltoniemi, Krista; Putkinen, Anuliina; Tuittila, Eeva-Stiina (Springer Science+Business Media, 2022)Peatlands are carbon dioxide (CO2) sinks that, in parallel, release methane (CH4). The peatland carbon (C) balance depends on the interplay of decomposer and CH4-cycling microbes, vegetation, and environmental conditions. ... -
Shoulder season controls on methane emissions from a boreal peatland
Jentzsch, Katharina; Männistö, Elisa; Marushchak, Maija E.; Korrensalo, Aino; van Delden, Lona; Tuittila, Eeva-Stiina; Knoblauch, Christian; Treat, Claire C. (Copernicus Publications, 2024)Cold-season emissions substantially contribute to the annual methane budget of northern wetlands, yet they remain underestimated by process-based models. Models show significant uncertainty in their parameterization of ... -
