The study aimed was to analyze long-term changes in stand structure and to perform a dendrochronological analysis in two stands converted to selection forest. Research measurements were carried out on two permanent research plots (50 × 50 m) in the Pro Silva Donovaly – Mistríky area in the years 1979, 1999, 2013, and 2024. On trees with a diameter at 1.3 m > 8 cm were measured for attributes such as diameter, height, and tree positions using Field-Map technology and simultaneously increment cores were taken from selected spruce and fir individuals for dendrochronological analysis Natural regeneration was monitored on transects by height categories. The results showed that the stands are approaching a selection model, with a diverse vertical and diameter structure. In natural regeneration Norway spruce was the most dominant species, while silver fir showed a decline, other species are minimally represented. Dendrochronological analysis showed a negative growth trend in spruce, while a positive growth development was recorded for fir. The findings contribute to a better understanding of selection forest dynamics and support planning of silvicultural interventions.
