Wright: Smithsonian Institution Scholarly Press. https://doi.org/10.5479/si.26880694 We calculated the number of pollen grains that were collected in a pollen trap per cm2. We used the following procedure: Our funnel pollen trap has a 9.5 cm diameter (area 70.88 cm2) and it is replaced once a year. During the processing of the content of the pollen trap, we add a ®Lycopodium tablet (Batch 938934) that contains a known number of Lycopodium spores (10,700). Then, we count both the total number of grains and the number of Lycopodium spores in the palynological slide that is obtained at the end of the processing. As we know the initial total number of Lycopodium spores (10,700) and the area of the trap (70.88 cm2), we use cross multiplication to calculate the total number of grains in the pollen trap and the grains per cm2 per year.
