Pielęgnowanie drzewostanów sosnowych pochodzących z odnowienia naturalnego w Nadleśnictwie Skwierzyna

Natural forest regeneration is gaining more and more importance in European forestry. The more widespread use of natural regeneration allows the formation of multifunctional and durable forests. Much attention was paid to the cultivation of pine stands, with particular emphasis on obtaining seedlings. However, few publications synthetically describe the care treatments in pine crops and young forests from self-seeding forest regeneration. Considering the importance of Scots pine in Polish forestry, it is justified to present the methods and ways of nurturing pine stands that come from the natural regeneration of this species. In the second or third year after initiating the natural regeneration of Scots pine on the clearing plot, a schematic thinning of the future cultivation is performed. For this purpose, the inter-row harrowing treatment on future cultivation is used with the Lowland disc harrow. In the last season, early cleaning is performed before the crop is closed. In the early stages of the development of pine seedlings, one cannot forget about the strong competition from herbaceous vegetation. Late cleaning, in the case of managing the crops of natural origin in the unit, is performed in two turns. Early thinning in this type of stand is usually carried out after 20 years of stand growth. The goals of maintenance pruning do not differ from those adopted as standard for planted stands. It should be clearly emphasized that when managing pine stands of natural origin in the Skwierzyna Forest District, the priority is to achieve breeding goals. The condition and quality of cultivated crops and young forests are always a priority for the owners of the local forests, regardless of the economic situation in the timber market or the demand for a given raw material in a given period.
