This research aimed to determine the variability of the part of the sessile oak gene pool from the area of the Natural Monument ?Kosutnjak Forest? at the level of one- and two-year-old seedlings, in the progeny test established in the nursery of the Faculty of Forestry. The research was conducted with one-year-old and two-year-old seedlings of 10 half-sib lines of the sessile oak. The heights and root collar diameters were measured, and the survival of the seedlings at the end of the second growth period, as well as the annual height and diameter growth, were determined. The results of descriptive statistics, one-way analysis of variance and Fisher?s least significant differences test, as well as multivariate analyzes - cluster and analysis of the main components were also presented in the research. The obtained results indicate a satisfactory level of genetic variability, which represents a good starting point for the realization of ex situ conservation of part of the gene pool, by establishing a field trial in the area of Kosutnjak and/or by introducing seedlings in smaller or larger groups to this area. In this way, part of the gene pool of the starting population, represented by seedlings of different half-sib lines, is permanently preserved, the number of the starting population increases, and conditions are created for continuous scientific and research work.

Enabling natural seed regeneration is important because natural stands grown from seeds are more productive compared to vegetative and artificial ones; they are also more resistant to adverse environmental factors and climate change. The aim of the study was to assess natural regeneration after clear-cutting in oak stands in the north-eastern Ukraine. The research was carried out in stands where regeneration cutting was carried out in years with different oak fruiting intensity. According to the recent inventory, the total regeneration quantity in clear-cut plots was from 16,800 to 28,900 stems ha–1, including 12,600–19,300 stems ha–1 of oak (60–85% of the total number), and a greater number of the regenerated oaks was recorded in the years of medium, good and very good acorn yield. It was established that the cutting must be carried out precisely in such years, preceded by pre-harvest cultural activities to promote oak natural regeneration. The composition of the formed young stands is optimal and meets the objectives of forest management in the study region.

Today, the problem of forest conservation and restoration in the context of progressive climate change and increasing anthropogenic pressure remains relevant. Our works have repeatedly noted that the conservation of the planet's biodiversity continues to be a topical issue, as it is a problem of our time. The development of methods and ways to restore forest communities' stands continues to be a priority in forestry, as forest resources are renewable, but require a fairly long period for restoration. Observations, assessment and control by environmental authorities are necessary, since in a changing climate, the reaction of natural systems leads to negative results, expressed in a decrease in the quality of wood, a change in the species composition. The article presents the results of studies of natural regeneration of forest stands in a protected specially protected natural area affected by human activity. The research work was carried out in the Janj forest, located in the southwestern part of the Republic of Srpska, in old-growth tree stands, the predominant species of which are beech, fir and spruce.
