The paper deals with determination of the rate of damage by red deer barking, determination of the rate of damage by a subsequent rot caused by Stereum sanguinolentum and the rate of its progress. The paper elucidates causes of the damage and quantifies depreciation of wood by rots in the Proklest Forest Range, the Křtiny Training Forest Enterprise “Masaryk Forest“. The deer barking caused damage to 85% of stands. In the most damaged 2nd and 4th age classes, rot caused by Stereum sanguinolentum was noticed in 89% of damaged trees. The greatest proportion is made by damage from the 70s of the last century. After the 80s, the damage occurred only exceptionally. The average percentage loss of wood is highest in the 2nd age class, viz. 38%. The determined progress of the rot ranged from 1 to 36.4 cm.year-1.
