Woody plant invasions into the Upper Volga natural communities

Abstract

The questions of woody invasive plant introductions into natural communities of the Upper Volga region are considered. It is established that, of 798 alien species of the region, 119 (14.9%) are woody plants, 27 tree and shrub species successfully naturalized and intruded into natural communities of various degrees of disturbance, and 7 species are included in the Black Book of Central Part of European Russia. The majority of invasive woody plants are species of Northern American origin. Examples of invasive woody species introduced into plant communities of the region, including the specially protected natural territories, are given.
