The paper presents the results of studies of biodegradation of Siberian fir (Abies sibirica) dry wood depending on the age of death in stands killed by Siberian silkworm (Dendrolimus sibiricus) and Ussuri polygraph (Polygraphus proximus). As an indicator of biodegradation of wood-sina the index of impact bending toughness was used. According to the results of the studies, it was found that the impact toughness of wood sharply decreases only in the first 3-5 years, which is apparently due to the most intensive biodegradation of wood during this period. In the future, the dynamics of biodegradation of stem wood of dry trees slows down sharply
