Structure of dendroflora and invasive activity of introduced species on the right bank of Dnipro

It was studied the ratio of strategy types of woody plants according to Ramensky – Grime, reflecting the ratio of two factors – availability of resources and disturbance of habitats. Species with a secondary strategy violent – stress-tolerants samples (47–65%) were predominant especially in protected forests and park forest ecosystems. Among them there are resistant to stress, lack of resources and competitively strong species: Quercus rubra L., Carpinus betulus L., Corylus avellana L., Acer campestre L., A. platanoides L., A. pseudoplatanus L. The second highest number of species with primary strategy there are stress-tolerant species – Acer tataricum L., Sambucus racemosa L., Genista tinctoria L., Aesculus hippocastanum L.
