|Abstract||In the conditions of the northern steppe forest vegetation zone forest stands Robinia pseudoacacia L. occupy an area of 7095.1 hectares. The range of types of forest conditions B1-D3: this species operates in eight edatopes. Age structure and distribution of growing stock of Robinia cannot be assessed as optimal: underwood occupies the lowest part of the area (3.0%), overripe forest stands make up the largest part of the area – 75.0%. Trend of changes in the rate of wood stock and its dependence on age is described by a logarithmic equation M = 101.67 ln (a) – 70.697. The bulk of the area is occupied by plantings of 1st quality class. A third of forest stands of Robinia pseudoacacia L. having indicators of 1st quality class are formed mainly under halogen variant of dry sudubrava.|
