This bachelor thesis is focused on species diversity and post-disturbance vegetation production in the context of forest regeneration. In 2004, the High Tatras' forests were damaged during strong windstorm which damaged 12,600 ha of forest land. A lot of opportunities for research were created as a result of this extensive damage. Our research was carried out 12 years after the wind calamity in 2016 and in 2018 samples were collected again to describe the change over a period of time. Two research transitions were established in the area of Danielov Dom and Horný Smokovec where we monitored these changes in biomass and vegetation species distribution. Significant changes in coverage were found mostly in Rubus ideaeus and in trees, coverage dropped mostly in Betula pendula which was caused primarily by nurturing. We also found bigger changes in frequency for example in species such as Calamagrostis arundinaceae, Galeopsis bifida and Carex pilulifera occurred. These changes are most affected by the increase in the tree component or the implementation of educational interventions. Using model plots we have found that the value of fixed carbon has increased tenfold over the time of two years. Tree production plays an important role in this aspect because change in biomass quantity of vegetation is caused by the rising of trees vegetation which caused the loss of ground vegetation biomass.
