Under the studied forest conditions, more numerous natural regrowth of pine is observed only in the first two years after the occurrence: in the control – 71%, in active foci – 78%, in fading – 85%, and in faded – 94% of the total natural regeneration of pine. Later, its abundance decreases sharply, unable to withstand competition with hardwood and in connection with the residual infectious stress in the foci of disease. The share of natural regeneration of pine older than 2 years in the control is 29%, in active foci – 22%, in fading – 15%, in faded – 6%. It is important to identify the share of oak in the natural reforestation in the areas of outbreak. It was established that in the existing centers of disease, natural regrowth and undergrowth of the oak amounted to 9.8%, in fading – 9.0%, in faded – 7.8% of the total number of young hardwood species. The numerous and viable undergrowth of deciduous species (94% of the total number of natural regrowth and undergrowth taken into account) allows to predict the upcoming change of species in the foci of the root sponge.
Key words: trees drying-out areas, annosus root rot, natural regrowth and undergrowth, natural reforestation.
