Cer in western Serbia. Data collection and processing on the experimental fields were carried out using standard dendrometric methods. The aim was to identify the most appropriate silvicultural treatments for converting these stands into a high forest structure, based on an analysis of their initial condition. The paper also presents the state of the stands before and after the applied treatments, allowing for a comparative evaluation. The investigated stands exhibited higher values of volume and volume increment compared to the average for Hungarian oak coppice forests in Serbia. Based on the analysis of site conditions, total volume, number of trees per unit area, and the dominant tree height, it was concluded that the stands could be converted into high forest through indirect conversion. The statistical significance of differences in mean tree volume and mean tree height between the experimental fields (EF) was tested using an independent t-test. The obtained values of stand parameters, together with the statistically confirmed differences in mean tree volume and height, indicate that the stand on EF I has higher productivity compared to the stand on EF II, which consequently required the application of different silvicultural treatments. In the stand on EF I, selective thinning was conducted due to the sufficient number of high-quality trees per unit area and the larger diameters and heights of dominant trees. Conversely, the condition of the stand on EF II suggested that postponing its conversion to a high forest form would be unjustified; therefore, the process of indirect conversion was initiated immediately through the application of a preparatory–regeneration felling. The conducted research highlights the importance of a detailed analysis of forest stand parameters as a basis for making appropriate decisions when selecting suitable silvicultural treatments for converting Hungarian oak coppice stands into a high forest. Sažetak: Istraživanje je sprovedeno u izdanačkim sastojinama sladuna, na planini Cer u Zapadnoj Srbiji. Prikupljanje i obrada podataka sa oglednih polja izvršena je standardnim dendrometrijskim metodama. Cilj istraživanja je da se na osnovu analize početnog stanja istraživanih sastojina definišu najprikladniji uzgojni tretmani za njihovo prevođenje u viši uzgojni ublik. Takođe, rad prikazuje stanje sastojina pre i nakon izvrešnih tretmana što omogućava analizu i evaluaciju istih. U istraživanim sastojinama zabeležene su više vrednosti zapremine i zaprmeinskog prirasta u odnosu na prosek za izdanacke šume sladuna u Srbiji. Na osnovu analize stanišnih uslova, ukupne zapremine, broja stabala po jedinici površine i gornje visine dominantnih stabala odlučeno je da se istraživane sastojine mogu prevesti u viši uzgujni oblik putem indirektne konverzije. Statistička značajnost razlika prosečne zapremine stabala, kao i prosečne visine stabala između oglednih polja ispitana je pomoću nezavisnog t -testa. Dobijeni taksacioni pokazatelji, kao i statistička verifikacija razlika prosečne zapremine i visine stabala, ukazuju na veću proizvodnost satojine na OP I u odnosu na sastojinu na OP II, što je za posledicu imalo izbor različitih uzgojih tretmana na oglednim poljima. U okviru sastojine na OP I sprovedena je selektivna proreda, s obzirom na dovoljan broj kvalitetnih stabala po jedinici površine, kao i više vrednosti prečnika i visine dominantnih stabala. Na osnovu zatečenog stanja sastajine na OP II, oodlučeno je da nema svrhe da se proces prevođenja u visoki uzgojni oblih odlaže, već da se u njoj odmah započne postupak indirektne konverzije primenom pripremno - oplodnog seka. Sprovedeno istraživanje ukazuje na značaj detaljne analize taksacionih pokazatelja kao osnove za pravilno donošenje odluka pri odabiru adekvatnih uzgojnih tretmana za prevođenje izdanačkih sastojina sladuna u viši uzgojni oblik.
