Hemes, Kyle S.; Chamberlain, Samuel D.; Eichelmann, Elke; Knox, Sara H.; Baldocchi, Dennis D. (2018): A Biogeochemical Compromise. The High Methane Cost of Sequestering Carbon in Restored Wetlands. In: Geophys. Res. Lett. 121 (8), S. 777. DOI: 10.1029/2018GL077747.
"Here we present 14 site years of continuous CH4 and CO2 ecosystem‐scale gas exchange over a network of restored freshwater wetlands in California, where long growing seasons, warm weather, and managed water tables result in some of the largest wetland ecosystem CH4 emissions recorded. These large CH4 emissions cause the wetlands to be strong greenhouse gas sources while sequestering carbon and building peat soil. The terms of this biogeochemical compromise, dictated by the ratio between carbon sequestration and CH4 emission, vary considerably across small spatial scales, despite nearly identical wetland climate, hydrology, and plant community compositions."
