Methane (CH4) is the second most important greenhouse gas contributing to the acceleration of greenhouse
effect and subsequent global warming. Boreal forests are considered to be a significant natural sink of CH4
(Dalal and Allen, 2008) due to a predominant soil uptake of CH4 from the atmosphere by CH4 oxidizing
(methanotrophic) bacteria (Smith et al., 2003). Therefore, the majority of studies have focused on
quantifying the CH4 exchange between boreal forest soils and the atmosphere. However, recent studies
have shown that plants can significantly contribute to the CH4 exchange between ecosystems and the
atmosphere (Rusch and Rennenberg, 1998; Pangala et al., 2014, 2015; Machacova et al., 2013, 2016).
Fluxes of CH4 have been mostly studied on herbaceous plants, whereas investigations on trees, particularly
boreal tree species, are still rare. Quantification and understanding these fluxes is, however, necessary for
a correct global CH4 inventory.
