title: Comparative analysis of pollen fall at three sites in south-eastern Poland.
abstract: The aim of the research was to study spatial variations in the abundance and seasonal patterns of pollen fall. The investigation was carried out at three sites of different land use during two pollen seasons (1995 and 1996). The sites were located in an average town (Ostrowiec Sw.), in a village (Brzostowa) and in the open area near Ozarow. With the use of the gravimetric method, 55 taxa of sporomorphs were determined. There were small differences in seasonal incidence and in total pollen sums between the three sites. The differences in the abundance and percentage values of chosen pollen taxa (Populus, Fraxinus, Pinus, Poaceae) were bigger. Tree and shrub pollen dominated in pollen fall at the three sites. The preliminary results suggest that the pollen data differed more between the years than between the sites, which was probably due to meteorological patterns.
