Ash-leaf maple ( Acer negundo L.) in coastal phytocenoses of the Vorona River.

Results of the estimation of dominance for individual species of woody and shrubby vegetation in the coastal phytocenoses of the Vorona River are presented. The data are indicative of a marked expansion of an alien species of ash-leaf maple ( Acer negundo L.) as well as its substantial invasive capacity. Estimates of the structure and degree of dominance expressiveness for the ash-leaf maple in the coastal phytocenoses of the Vorona River are provided. [ABSTRACT FROM AUTHOR]
