Koskinen et al 2012: First Results of CH4 Measurements from Pristine, Drained and Restored Spruce Swamp Forests in Southern Finl
Theme X. Peatland carbon budgets and greenhouse gas (GHG) fluxes
CH4 emissions were measured using a closed-chamber discrete sampling technique during the summer and autumn 2011 on pristine, drained and restored meso- and meso-eutrophic spruce swamp forests in the south boreal vegetation zone in Finland. First results indicate that contrary to expectations, draining of a spruce swamp forest does not affect CH4 emissions. Intra-site differences were greater than inter-site differences, with largest emissions measured from ditches on the drained and restored sites and from the mire edges on the pristine sites.
