Table 7 Correction factors by tree genera by individual study and summarized (averaged) by continent and for all studies. Pollen representation relative to tree census data were based on the following correction factor ranges: underrepresented > 1.25 (blue), representative = 0.75–1.25, and overrepresented < 0.75 (orange). Final genera designations of underrepresented, representative, or overrepresented were based on correction factors from all studies (last column)
