Fire Damage to Boreal Forests of Siberia Estimated Based on the dNBR Index

The impact of fire on the boreal forests of eastern Siberia was analyzed using the normalized burn ratio (NBR) and its pre- versus post-fire difference (dNBR) applied to Landsat-8/OLI data. We provided the classification of fire impact in relation to dominant tree stands and vegetation types. For post-fire areas of different disturbance levels, we evaluated the 5-year dynamics of restoration processes in terms of anomalies in the surface temperature (ΔT/Tbg, %) and in the Normalized Difference Vegetation Index (ΔNDVI/NDVIbg, %), which can indirectly characterize the post-fire state of vegetation and recovery.
