Abstract

The study was carried out in a mixed stand where Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth.) dominate, at the Koryukivske Forest Enterprise and Semenivske Forest Enterprise (Eastern Polissya, Ukraine). The aim of the research was to compare stand parameters, productivity and health conditions of birch and mixed pine stands of the second generation, planted after clear felling of pine stands affected by root rot. According to the non-parametric Kolmogorov-Smirnov goodness-of-fit test (λ), compared empirical populations of the trunk number distributed by their thickness depending on the average diameter of a stand in the root rot damaged sites and on control (non-damaged sites) belong to different parent populations, and follow the different curves. Due to pathological losses, density and timber volume in mixed planted pine stands in the root rot damaged sites are much lower (by 15–62 % and 15–59 %, respectively) than in non-damaged sites. The average diameter of living pine trees in the root rot damaged sites is 12% different in both directions, comparing with non-damaged ones. In the root rot foci, the thicker trees (on average on 15-42% in comparison with the non-damaged sites) die off. Therefore, in a mixed stand, birch trees are more resistant to the root rot and have a significantly better health than pine trees.
