Summary

Were measured specific methane fluxes that are representative for some peatland landscapes of Western Siberia forest-steppe. Specific methane fluxes of forest-steppe eutrophic mires are very close to the same fluxes in subtaiga. Probability distribution of specific methane flux has following parameters: 1st quartile/median/3rd quartile = 0.53/1.99/6.03 mgC-CH4·m^-2·h^-1. Methane fluxes from bog lakes are close too, as in subtaiga they are estimated at tens and first hundreds of mgC-CH4·m^-2·h^-1. Probability distribution of specific methane flux in riam: 0.00 / 0.09 / 0.21 mgC-CH4·m^-2·h^-1. Annual methane emission from Western Siberia forest-steppe (estimated on the model Bc5) is 0.36 MtCH4/year that form 5 % regional emission
