Transformation of Forest Litter Properties under Controlled Burning of Fir Forests Defoliated by Siberian Moths in the Lower Angara River Basin

摘要

The results of studying the dynamics of forest litter properties in the loci of a Siberian moth (Den-drolimm sibiricus) mass outbreak arc considered. As a fir forest defoliated by this pest burns, the reserves and fractional composition of the forestlitter, its actual acidity, and its chemical composition drastically change. Upon the burning out of such forests, the litter complex of invertebrates is fully destroyed and begins restoring only two years after the fire.
