The Structural-Dynamic Organization and Trends of Forests Reconstitution in the South-Western Pre-Baikal (Irkutsk Region, Siberia)

Abstract

At the territories of three key sites with different environmental conditions (coast of Irkutsk Reservoir, the Goloustnaya River basin, surroundings of Gakhany settlement in 60 km northward from the urbanized area Ust'-Orda, Irkutsk Region), we performed studies aimed to reveal the structural-dynamic organization and trends of forests reconstitution at the places of burnt areas and of cuttings of different targets. We took into account the character of impact of anthropogenic factors due to modern land use in the region, in particular. A considerable limitation of cuttings during last decades and decrease of areas was designed for agriculture and pasture on the background of climate dynamics and variability in the region during last years.
