The work analyzes the meteorological element air temperature at three climatological stations. The aim was to assess changes in the values of temperature sum, and the sum of active temperatures (sum of temperatures over specified threshold) and the sum of effective temperatures (sum of temperatures over specified threshold - defined threshold) for the period 1961 - 2010. At the same time large vegetation season (number of days when the average daily temperature is consistently above 5 ° C), the main (number of days when the average daily temperature is consistently above 10 ° C the growing season) and the growing years (number of days when the average daily temperature is consistently above 15 ° C) was analyzed. These results were then compared with the proxy data from the field of plant and animal phenology. Pedunculate oak or English oak (Quercus robur) was chosen as a representative for the higher plants and the Great tit (Parus major) was chosen for the represenatives of the bird species in the Lednice area. On the basis of calculating the sum of active and effective sum, we can say that their values increase with time, as far as the number of days in the growing seasons. The results are regionally different.
