The article presents the data of aeropalynological research in Ivano-Frankivsk during the period of 2013–2015 years. The features of quantitative dynamics of pollen of Betula species have been revealed in the air of the city. The influence of key meteorological factors on the course of pollination of the genus Betula has been analyzed. It has been established that the most intense pollination takes place at the temperature from +10 to +19°C and humidity of 58–70 %, the average duration of pollen season is 25 days. The data show a significant effect of predominant wind directions and average temperature on the development of the aeropalynological situation in the city. The beginning and end of pollination were found and days when the pollen concentration was the highest.
