Abstract
The oak-spruce stands in Podillya region in fresh hornbeam oak forest type were studied. Comparison of productivity of oak stands with and without spruce introduction in the initial stand composition was performed. The dynamics of productivity change and distribution of oak and spruce trees by diameter were analyzed. It was found that there is an opportunity to get 70–130 m3 of wood additionally in oak and spruce stands up to 40–50 years in Podillya. The optimal is two-stage stand cutting by felling spruce at age of 40 and 60 years. The intensity of the first stage should be 30–50 % with further cutting the reserved part. The most appropriate method is to conduct the first cutting of spruce trees of Kraft classes 1 and 2 to reduce the competition impact on oak. Later spruce felling leads to oak inhibition and reducing its productivity.
