The role of Polygraphus proximus Blandf., an invasive bark beetle of Far Eastern origin, in the transformation of taiga ecosystems of the plains of Western Siberia is evaluated. It is shown that this species is currently one of the main factors of degradation of the Siberian fir forests and various changes in their ecosystems. The consequences of invader outbreaks in fir forests of the region are massive mortality of forest stands, reduction in the number of and deterioration in the vitality of fir undergrowth, and significant changes in the species composition and structure of the vegetation cover and xylophilous insect fauna.
