INVASIVE DENDROFLORA OF MIDDLE RUSSIAN FOREST-STEPPE ZONE: STRUCTURAL AND BIOGEOGRAPHICAL ASPECTS OF THE STUDY
In this paper invasive flora is considered in the context of structural-biogeographical approach. The aim of the research is the analysis of the structural organization of invasive dendroflora, which is conducted by the ratio of the basic taxonomic, biomorphological, ecological phytocoenotic and botanical-geographical units. Biogeography of plant invasions in the study area have allowed identifies four groups of invasive species, taking into account their resettlement in conditions of the North, typical and southern forest-steppe. The result is an annotated list of dendroflora of Middle Russian forest-steppe zone - a basis of studying of plant invasions in the region.
