The climatic changes have brought about numerous injuries on trees, which along with damages caused by the anthropogenic factor, leads to occurrence of numerous wood-decay fungi in the stands. For the purposes of protection and preservation of beech in Serbia, this paper researched the occurrence of pathogenic microorganisms on beech trees relative to the presence of injuries on trees. The testing was conducted in the Forest Holding Kucevo, in a hillside beech forest Fagetum moesiacae submontanum of generative origin. The research was carried out on 23 testing plots with a total of 324 trees. It was found that the appearance of fungi primarily depends on the presence of mechanical damage on trees (as much as 73.46%), while the presence of abiotic damage has almost no bearing (only 3.21%), which indicates that the health condition of high beech stands is heavily dependent on careful and proper manipulation during harvesting. Each injury inflicted on a beech live tree during logging opens the door to infection with pathogenic microorganisms.
