“…To date, many Ukrainian scientists have studied the natural regeneration of pine after clearcut at different times (Fuchylo 2011;Maurer et al 2013;Levchenko, Mazurenko 2017;Maurer, Kimeichuk 2020) and foreign scientists (Dong et al 2003;Andrzejczyk, Żybura 2012;Dobrowolska 2015;Czyżyk 2017;Aleksandrowicz-Trzcińska et al 2018;Bílek et al 2018;Saursaunet et al 2018;Długosiewicz et al 2019;Przybylski et al 2021). Fuchylo (2011) described the abundant natural regeneration in the humid forests of Eastern Polissya.…”

Scots pine (Pinus sylvestris L.) forests belong to the most relevant forest types in the Western Ukrainian Roztochia area. The promotion of close-to-nature forest management in Ukraine in the framework of the forest strategy 2 035 supports natural regeneration and the application of diverse felling methods beyond clearcutting. In the present study, natural regeneration was analysed in mixed Scots pine stands on poor and relatively rich soils, after small clearcuts, shelterwood cutting and gap fellings (with or without soil preparation), with respect to tree species composition, species abundance and height growth. It could be shown that Scots pine is the most abundant species in all the felling systems, with on average more than 100 000 plants per ha on poor soils. Other admixed tree species only occur with small shares. Natural regeneration, especially of Scots pine, was less abundant on rich soils and in shelterwood, compared to a small clearcut. After the young plants have established, their abundance declined in the second and third year due to competing herbaceous plants and thick litter.

In recent years, particular attention has been paid to enhancing the meaning of natural regeneration, which is a part of the implementation of the concept of sustainable development and is one of the pillars of the natural direction of forest silviculture. Since the middle of the last century, the contribution of natural regeneration in Poland has been steadily increasing.The paper presents the analysis of density and variability of growth traits of natural regeneration of Scots pine (Pinus sylvestris L.) in south-eastern Poland. The study involved four compartments, which were prepared with the use of tiller and plough (active and double mouldboard). Density of seedlings, their height and root collar diameter, were measured.Density and growth characteristics of seedlings were higher at the tiller area and furrow compared with nonscarified soil and ridge. The highest cover with herbaceous plant was reported in ridges and non-scarified soil, but in most of the analysed compartments, it had no effect on the density of seedlings. It was found that different methods for soil preparation create different conditions for germination of seeds, which is reflected in the number of seedlings and its growth traits.

Scots pine (Pinus sylvestris L.) is a widespread species in Eurasia, but its natural range can be significantly altered by a variety of stressors. The ability of pine to regenerate naturally is significantly reduced by its occurrence in unsuitable habitats. The processes of natural selection of pine from select habitats can be followed in stands of national parks where forestry activities are excluded. The possibility of pine regeneration is influenced by the following factors: characteristics of produced seeds, competition, and genetic characteristics. In the present study, selected factors associated with limiting the natural regeneration potential of pine were analysed. The present work generated important information related to the natural regeneration potential of pine in Central and Eastern Europe. The main objective of the analyses was to discuss the possibility of the natural regeneration of pine stands without human intervention. In addition, the genetic diversity of naturally germinating seedlings was analysed. The obtained results confirmed the high reproductive potential of pine despite the advanced age of the studied trees. The obtained seeds produced by old growth Scots pine trees had high viability, while a significant difference was observed in terms of the average number of cones per dominant tree between studied stands. Thus, the number of cones was the main element determining the regeneration potential of the stands. It should be emphasised that the number of cones did not influence the occurrence of natural regeneration. Based on the obtained results, the regeneration potential of pine stands depends mainly on the habitat and the competitive pressure. In addition, a correlation between genetic parameters and the regeneration potential of stands should be established, which may be the beginning of further research on the process discussed in this publication.
