Abstract We investigated the trade-off between accuracy of results and practical applicability of using pollen trap samples to record the pollen flora of an area.We calculated the minimum representative amount of trapped pollen that needs to be measured.We systematically examined the bee flora of an area for a 2-year period to determine the necessary frequency of sampling.We concluded that even 5 to 10% of the total trapped pollen can give sufficient information about the pollen sources of an area. Moreover, samples of 3-day trapping duration collected at 6- to 9-day intervals through one year were sufficient to catalog the pollen flora of the area.
