relative pollen frequency (RPF) Expression of pollen data from sediments for each species, genus, or family, as a percentage of the total pollen count, or the total tree pollen. It is the traditional and most widely used method for preparing pollen diagrams. Compare ABSOLUTE POLLEN FREQUENCY. See also POLLEN ANALYSIS.
