century compared with the historical  estimate. This moves forest composition towards greater contribution of hardwoods  . This shifting was also proved by observations in northern Mongolia, where boreal forest fires likely promote the relative dominance of B. platyphylla and threaten the existence of the evergreen conifers, Picea obovata and Pinus sibirica . For Tuva Republic, warming ambient temperatures increase the potential evapotranspiration demands on vegetation, but if no concurrent increase in precipitation occurs, vegetation becomes stressed and either dies from temperature-based drought stress or more easily succumbs to insects, fire, pathogens or wind throw . Although Torzhkov et al.  also projected fire risk  increase in Tuva Republic, they expect FR decrease in the Irkutsk region and Yakutia under RCP8.5, and FR decrease in major parts of Central and East Siberia under RCP4.5 for 2090-2099. This discrepancy is due to differences in models, climate projections, fire severity metrics and other assumptions. According to global projections, FR will increase in Central Asia, Russia, China and India under a range of scenarios .
