What drives European beech (Fagus sylvatica L.) mortality after forest fires of varying severity?

Post-fire beech mortality depends on fire intensity and related severity. Low fire severity results in a mortality rate comparable to the unburnt forest. Moderate fire severity results in delayed mortality of smaller individuals but large seed trees survive. High fire severity causes a rapid dead irrespectively of beech’s diameter. Post-fire fungi infestation play a major role in triggering beech mortality.
