No attempt here is made to separate prairie and savanna because over much of the area it cannot be done reliably on the basis of the presettlement data. However, much of the area south and west of Lake Michigan was prairie, whereas much of the area in Michigan was Oak savanna and Oak woodland with prairie glades.

Publications and diaries of early travellers and botanists were checked for references to the Rice Lake Plains, including particu- larly the works of Catharine Parr Traill (1836, 1868, 1885) and John Macoun's catalogue (1883, 1884, 1886a, 1886b, 1888, 1890a, 1890b). The National Archives and Queens University Archives were also checked for any relevant unpublished information gathered by early botanists including John Macoun and Catharine Parr Traill.
