The regularities of growth and development of black poplar in various plantings and forest growing conditions are revealed. It is established that the highest tree stands of black poplar are on average 30 m. With a trunk diameter of 44 cm, a class I bonitet, a fullness of the studied rock in a stands of 0, 5 and a stock of wood per 1 ha of 206 m3 are formed in the nettle. The black poplars that grow in the oak forests of the trees have the lowest productivity. The height of the trees and the diameter of the trunks in these forest conditions are on average 42, 1−57, 0 % and 1, 6—1, 8 times less, respectively, than the stands formed in the nettle and the pine-shrub pine forests, as well as by 31, 5 and 33, 3 % of the trees growing in vegetation near the riverside. The black poplar quality class in this type of forest is IV, and the stock of raw wood per 1 ha was only 54 m3, with the standing tree of the studied species of 0, 4.
