Quantitative and qualitative characteristics of forests in the Baikal Mountain Forest region

Abstract

The article considers modern approaches to the study of the state of forests of the Baikal Mountain Forest region. All the obtained results of field studies are confirmed by a 13-year period of observations of the changes in the quantitative and qualitative indicators of growth and development of forests, the selected object. During the research, about 17 thousand ha of forest area were surveyed, 1570 permanent test areas were laid. According to the sanitary condition, the share of healthy plantings (class 1) accounts for 76.5%, the 2nd class of resistance (with the presence of small damage and signs of weakening) – 11.1% the indicators of other classes of resistance of plantings vary from 0.5% to 2.6%. The main sign of damage and weakening of forests are grass-roots fires – 60.3%. The total stock of wood according to the GIL is 2568.9 million m3. Coniferous species have the largest share of the stock of business trees – 94.3%, a smaller share of the stock – soft-leaved – 5.6%. The obtained data allow us to develop measures for rational forest management for part of the forests of the Republic of Buryatia, the Trans-Baikal Territory and the Irkutsk Region.
