The experimental site is situated in ecosystem of floodplain forest in alluvial plain of river Dyje near by town Lednice in South Moravia in the forest type group Ulmi-Fraxineta carpini. Over the time span of sixty-two years, the average annual temperature in this area increased by 1.5 oC and the average spring temperature increased by 2.0 oC. Overall, the phenological events of the tree component advanced the beginning of foliage by 10.0 days and full foliage by 9.2 days. For each of tree species the sums of effective temperature with threshold value 5 oC were detected. The conclusion of this study is that the phenology of trees, shrubs, herbs and birds in the floodplain forests of South Moravia was influenced by the regional climate change. Our contribution to the publication is focused on the tree floor. All the characteristics has changed in the correlation with the increase of the annual and spring air temperature.
