The submitted paper presents the results of a phenological research of herb layer of Carpinion betuli community which was realized on the locality of the Báb forest in 2012 and 2013. During 2012, there were 25 species recorded in an herbal layer and for a phenological research in 2013, I was able to document 24 taxa. In 2012, the highest number of present species in a phenological spectrum occurred. Especially, it was during March and October. In 2013, the highest number of species in a phenological spectrum was found on March and April and also later from September to October which is a period when forest species start to grow because of a temperature increase and it also occurred in the autumn period when a repeated growth of forest species took place. In 2012, species in generative phases occurred from 11th March until 1st September and after that, taxa in vegetative phases were found only. In 2013, because of low March temperatures, it was possible to observe generative phases only since 22nd March until the last date of a phenological observation – 11th December. A change in the onset, interphase duration and ending of the monitored phenophases between the years 2012 and 2013 was observed. Specifically, a shift in the onset of the vegetative and generative phenophases was noted. This distinction was caused by a different average week temperature measured in 2012 and 2013. In March 2013 a significant temperature decrease and even ground frost occurred.
