Stand structure analysis was conducted before and after natural regeneration
(on the same plot) on a site of monodominant sessile oak forest (Quercetum
petraeae Cer. et Jov. 1953., subass. tilietosum). In this stage individual
old sessile oak trees were still remaining in the stand. Before the
regeneration in the 150-yr-old stand in 1992 only sessile oak was
rep?resented in the upperstorey. The trees mostly had irregularly developed
crowns and reduced growth potential. These were the elements used in
planning the regeneration in management plans. Besides the remaining
individual old sessile oak trees, silver lime dominates in the young stand
in 2017. In the stand structure there is no biological potential of sessile
oak trees that could represent the basis for further development because the
sessile oak trees are suppressed by silver lime towards the understorey and
even the herb layer. Because of the undefined significance of the silver
lime in the stand, transient management was prescribed in the man?agement
plan so a reconstrucion of the stand should follow in one of the next
management periods in order to restore sessile oak on the site as it was
suppressed due to an inedequate regeneration procedure. On the basis of the
studied stand structure of the young stand, the abandonment of the transient
management concept is recommended and introduction of the intensive
management approach of slver lime in the current rotation. This was based on
the available number of silver lime trees of good quality in the stand, i.e.
the aspirants for tending by means of selective thinning and their strong
growth response four years after selective thinning. Old sessile oak trees
that are still present in the stand are only a simulacrum of the continuity
of the current stand with the previous one and they should be removed by
means of intensive and rationalized tending of silver lime, and partly
integrated in the silver lime stand.
