Abstract

An analysis of CO2 emissions and soil microbiological activity has been performed in larch stands of different ages that developed on cryogenic soils and represent different stages of post-fire succession. An abrupt increase in the soil emissions of CO2 (by more than 2 times) in young stands (15–30 years old), as well as a decrease of soil-respiration rate at the later stages of pyrogenic successions because of the restoration of the moss-lichen cover and the closure of the stand canopy was seen. Intraseasonal and interannual variations of soil CO2 fluxes were also revealed; however, their dynamics was largely determined by the local conditions.
