Natural disturbances combined with climate changes are becoming important part of forest
management. In this master's thesis, based on previous research, various quantitative
methods of verifying success of forest restoration after natural disturbances were analyzed.
In the second part of research, three examples of forest stands were analyzed, in which
situational thinning and classical thinning were compared. It was established that
quantitative analyses of seedlings could be performed relatively quickly. Implementation of
these methods is reasonable especially in stands, damaged by natural disturbances. It was
also concluded that, beside qualitative analyses, a quantitative analysis of forest regeneration
represents an important part of damaged forest restoration. Research objects were proved to
be well regenerated, with due regard to pioneer species. Adequate tending of younger forest
stages is crucial for proper forest restoration. On three selected examples of forest structure
analyses it was found that on well-rejuvenated stands it makes sense to use situational or
adapted classical thinning. On poorly rejuvenated stands it makes sense to use situational
and group thinning. Results indicate possibility of rationalizing tending by reducing number
of selected trees, not reducing pioneer species and adjustment of reduction of hazel bushes.
