Climate change impacts on forest conditions will increase fire risks in the Central Appalachians by the end of the century

An analysis of fire probability across the globe found the majority of models projected an increase in wildfire probability by the end of the century. This agreement is particularly high for temperate coniferous forests and temperate broadleaf and mixed forests, where fire probability models were most sensitive to mean temperature of the warmest month. If temperature and evapotranspiration increase drying of the forest floor in spring, amplify the effects of declining precipitation, or overwhelm modest precipitation increases, the annual area burned and length of the fire season will likely increase. If drought or prolonged dry periods increase in this region as expected, fire risk will increase in both forests and local communities. For example, abnormally dry conditions in 2016 resulted in widespread wildfires across 17,000 acres and damaged or destroyed nearly 2,500 structures near Gatlinburg, Tennessee. Interactions between complex patterns of land use and ownership, forest fragmentation, and both human and natural ignition sources, may ultimately determine how an increase in fire weather conditions might be manifested (Clark et al. 2013).
