This study was performed to investigate the pollen influx of arboreal (AP) and herbaceous plants (NAP) falling to the unit soil surface (cm2 /year) in the three samples areas, where the vegetation is different, and to find out the relationship between the meteorological parameters and pollen influx values during 2007-2009 in the Research Forest of Faculty of Forestry of Istanbul University. Tauber-type pollen traps were placed to three separate sample areas (forest, forest edge and open area) and replaced monthly. Whereas the pollen influx of arboreal plants (AP), Carpinus sp., Castanea sativa, Quercus sp. and Pinus nigra has the most annual influxes on the soil for the first period (2007-2008), the pollen influx of Fraxinus sp., Alnus sp., Quercus sp., Pinus nigra and Cupressaceae has the most annual influxes for the second period (2008-2009). While the pollen influx of herbaceous plants (NAP), Plantago sp., Poaceae and Caryophyllaceae families has the most annual influxes between 2007 and 2008, the pollen influx of Poaceae, Asteraceae families and Plantago sp. has the most annual influxes between 2008 and 2009. When the pollen influx of herbaceous plants was increased in the open area, the pollen influx of arboreal plants was increased within the forest. Pollen influx during 2008-2009 was lower than the period of 2007-2008, because of heavy rain.
