SUMMARY

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.
