Abstract
The microfossil succession in ten bog deposits of northwestern Wisconsin was determined in an effort to trace the post Pleistocene floral history in that region. The deposits were selected with reference to the shorelines of Glacial Lakes Duluth, Algonquin, and Nipissing in order that stratigraphic comparison of the fossils might be accomplished. These comparative studies indicate that upon each area of land that was progressively uncovered by the waters of the glacial lakes there developed a pioneer forest of Picca and the subsequent development upon these areas appears to have been in response to the soils. The general forest succession on the heavier soils of the region appears to have been (1) Picea, (2) Pinus, and (3) mixed hardwood forest. On the lighter soils the suggested succession is (1) Picea and Pinus Banksiana, (2) P. Banksiana and P. resinosa, and (3) P. resinosa and Quercus forest.
