Устойчивость темнохвойных лесов Прибайкалья к «новым» болезням

Abstract

The recent damage to dark coniferous forests in the Baikal region which were not previously noted in the region have an unclear etymology and not established scales. Most likely, the revealed damages of dark coniferous forests in the Irkutsk region and Buryatia have an initial cause of worsening of the chronic course of bacterial diseases of conifers that were not previously noted in the region and therefore are referred as «new diseases» of dark coniferous forests. On these background there is possibility increase a negative effect of micromycetes and insect pests. A particular danger is a significant reduction in the level of atmospheric humidification of these forests which can lead to their mass drying. An urgent examination of the stands is necessary in order to determine the methods of combating bacterial damage.
