چکیده
The dynamics of fires in the territory Eastern Siberia (the Lena River basin middle reaches) has been studied with use materials from retrospective satellite imagery. dependence burnability forests local territories on level heat and moisture supply is shown. range index number area fires) for study under extreme drought conditions was revealed, confirmed by data. It shown that potentially average annual values can be 2.5 times higher than current statistics. Based invariant NDVI NDWI indices, a changes characteristics post-fire areas identified, which indirectly determines fire impact vegetation humidification regime.

Post-fire forest regeneration is strongly influenced by abiotic and biotic heterogeneity in the preand post-fire environments, including fire regimes, species characteristics, landforms, hydrology, regional climate, and soil properties. Assessing these drivers is key to understanding the long-term effects of fire disturbances on forest succession. We evaluated multiple factors influencing patte...
