Boreal forests are warming faster than the rest of the globe, leading to more frequent and severe wildfires. A main component of boreal forest recovery is mycorrhizal fungi, which establish mutualistic symbioses with host plants within the roots and soil. However, this symbiosis may be threatened by high severity fires, which burn the canopy of trees and the soil. This review will evaluate the current literature on high severity wildfire and mycorrhizal fungi in boreal forests.
