Wildfires and logging play an important role in regulating soil carbon fluxes forest ecosystems. In Siberia, large areas are disturbed by fires annually. Climate change increasing anthropogenic pressure have resulted the expansion of recent decades. However, few studies focused on effects these disturbances CO2 efflux vast Siberian areas. The objective our research was to evaluate differences from soils atmosphere between undisturbed sites affected wildfire Scots pine forests southern Siberia. We examined 35 plots (undisturbed forest, burned logged plots, plots) six study Angara region four Zabaikal region. Soil measured using LI-800 infrared gas analyzer. found that both fire significantly reduced first years after a disturbance due reduction vegetation biomass consumption floor. substantially lower high-severity (74% less compared forests) than moderate-severity (60% less) low-severity (37% fires.
