Abstract


Forestry and taxation indicators of oak and spruce crops in the terms of the hornbeam oak forest of the southern part of Right-Bank Forest-Steppe of Ukraine are studied. Actual and potential productivity of one age oak and spruce and oak forests on indicators of growth, average change in inventories and preservation are compared. The dependence of productivity of oak and spruce crops from mixing schemes and origination schemes is determined. It is found that the oak shows aggression concerning the spruce, in dry years it displaces the spruce from the planting by capturing soil moisture. The spruce loses biological stability and massively disappears from the planting. Inexpediency of silvicultural production of oak and spruce plantings in the region of investigation is proved.
