The aim of this work is to evaluate the vegetation changes that have taken place in Bayerova Nature Reserve over the last 35 years. 14 phytosociological plots and 2 transects were renewed for this purpose. These were originally established by Koutecký in 1982. Data were collected according to the original methodology. Vegetation changes have been determined based on the principal component analysis (PCA) and fidelity rates. European beech has expanded to the detriment of other trees, especially Norway spruce and Sessile oak. Individuals of these species died as a result of their deteriorating conditions. Additionally, there was no evidence of their regeneration. Most plots are now moister and more nutritious. As a result, more nutrient-demanding species appeared in the plots. Number of light-demanding and heat-tolerant species has decreased. The results also showed homogenization. A similar trend is observed in other Central European countries |
