Wildfires Dynamics in Siberian Larch Forests
- Studies wildfire number and burned area temporal dynamics within all of Siberia and along a south-north transect in central Siberia (45°–73° N) based on NOAA/AVHRR (National Oceanic and Atmospheric Administration/ Advanced Very High Resolution Radiometer) and Terra/MODIS (Moderate Resolution Imaging Spectroradiometer) data and field measurements for the period 1996–2015
- Also analyzes fire return interval (FRI) along the south-north transect was analyzed
- Finds that both the number of forest fires and the size of the burned area increased during recent decades (p < 0.05)
- Finds significant correlations between forest fires, burned areas and air temperature (r = 0.5) and drought index (The Standardized Precipitation Evapotranspiration Index, SPEI) (r = −0.43)
- Finds that within larch stands along the transect, wildfire frequency was strongly correlated with incoming solar radiation (r = 0.91)
- Finds that fire danger period length decreased linearly from south to north along the transect
- Finds that fire return interval increased from 80 years at 62° N to 200 years at the Arctic Circle (66°33’ N), and to about 300 years near the northern limit of closed forest stands (about 71°+ N) and that the increase was negatively correlated with incoming solar radiation (r = −0.95)
