In the thesis, we studied regeneration on the Pahernik property, focusing on the
occurrence and development of young trees up to 10 cm in diameter at breast height. We
analysed density, developmental stages, effects of ungulate browsing, tree species mixture, and
effects of basal area. Young trees were recorded in 363 subplots across the entire property,
which ranges from 350 m to 1543 m above sea level. We found rather low tree regeneration
densities in subplots A (276 individuals/ha), B (994 individuals/ha) and C (15,924
individuals/ha), with no marked differences between altitudes and spatially separated parts of
the property. Norway spruce was the dominant species (38%), followed by silver fir (32%) and
European beech (26%). Tree regeneration covered 24% of the soil surface and ground
vegetation 11%. Herbivorous game has influenced the decline of the fir, especially in the height
class up to 1.3 m, with a progression in height levels, indicating a growing problem of
overbrowsing. The average browsing of regeneration up to 1.3 m was 33% and of silver fir
39%. The density of young trees decreased with increasing sub-plot size, as larger and older
trees were inventoried there. The tree species mixture of the regeneration has changed
favourably compared to the previous inventory, with a decreasing proportion of Norway spruce.
We didn’t confirm correlation between the density of regeneration and the height of the basal
area. We conclude that the tending of the regeneration was reasonable, as the proportion of
released target trees is satisfactory. Good information on regeneration process is essential for
action planning, monitoring and sustainable forest management.
