In 1957, a study was begun to survey, sample and evaluate the northern boreal forests of the Great Lakes Region. Quantitative data of tree and herbaceous composition were collected for 110 upland forest stands selected on the basis of boreal relationships, throughout the Great Lakes region from Minnesota to Ontario. Only stands free from disturbance in the lifetime of the existing trees and of at least 15 acres in size, were sampled by the quarter method. Relative frequency, relative density, and relative dominance were calculated for all tree species in all stands. These 3 relative values were summed to provide an importance value. Frequencies were determined for all herbs and shrubs on the basis of their occurrence in meter square quadrats. Two major treatments were attempted. The first assumed the controlling effect of site moisture on plant relationships. The second treatment can be considered purely phytosociological in that only the quantitative aspects of species themselves were employed in placing the stands in spatial relationship to each other.
