The pollen‐vegetation relationship in southern Michigan: An application of isopolls and principal components analysis

Abstract

Maps of the modern pollen from southern Michigan show that the patterns in the vegetation are derivable from pollen data. The pollen maps reveal the differences at the formation level, i.e., between the deciduous forests and the mixed conifer‐hardwood forests, and the differences at the forest‐type level, i.e., between the pine forests and the northern hardwoods and between the oak‐hickory forests and beech‐maple forests. Maps showing the isopolls for individual pollen types and the distribution of principal components derived from the pollen data are used to illustrate these results.
