The paper reports the “Yearly Airborne Pollen Calendar” of 2000. The monitoring station is the “2-hourly Airborne Pollen Monitoring Station” of the Botanical Garden/Geophysical Observatory of the University of Modena and Reggio Emilia.In 2000 the Total pollen yearly sum was approx. 33,000 p/m3 /24h (Trees = 55%; Herbs = 45%; p= pollen grains). The months with the most pollen were February and April, all “3 Star” months (around 5000 – 6000 p/m3/24h-monthly sum); the daily maximum was recorded on February 24 (1314 p/m3/24h) and the 2-hourly maximum on February 24 (4950 p/m3/2h). Altogether 90 pollen types (8 - 58 per month) belonging to 47 Families were identified. The most abundant pollen types, which reached a monthly sum higher than 500 p/m3 (Classes IV, V, VI) were 10: Ulmus (February), Populus (February, March), Cupressaceae (February, March, April), Ostrya/Carpinus orientalis (April), Platanus (April), Quercus (April), Gramineae (April, May, June, July), Plantago (July), Castanea (June, July) and Urticaceae (July, August, September).
