Abstract: The article presents the findings of aeropalynological research on the urban ecosystem of Ivano-Frankivsk City (the Precarpathian Region, Western Ukraine) over the spring period of 2013. The following pollen grains were observed to dominate in the aeropalynological spectrum of the city: Corylus and Alnus (in March and the first half of April), Carpinus, Betula and Populus (in the second half of April), and Pinaceae (in May). The analysis involved the pollination onset, peak and cessation in the abovementioned taxa as well as the regularities in pollen concentration dynamics with regard to the meteorological situation in the city. The findings show a significant effect of predominant wind directions on the development of the aeropalynological situation in the city. Pollen concentrations of the following taxa were found to exceed the clinically important threshold value: Corylus and Alnus pollen, during four pollination days; Carpinus and Betula, during twelve days. This indicates the necessity for systematic aeropalynological monitoring in the city.
