Minnesota Land Use/Cover: Historic
This page describes land
use/cover data and maps from
the mid-1800s, as recorded at the time of European settlement,
as well as earlier reconstructions from fossil pollen records.

- General Land Office records: Surveyors laying out Minnesota's public land survey system in 1848-1907 recorded the
size and species of the larger trees they used as markers (bearing trees),
as well as general descriptions of the physical geography of the landscape
they traversed. Although not a complete vegetation survey, the General
Land Office records provide much valuable detail about how the state
looked at the time of European settlement.
- Map of the Original Vegetation of Minnesota ("Marschner's
Francis J. Marschner interpreted the notes from the General Land Office
records to create a large state map showing how Minnesota looked at the
time of European settlement.

See particularly the sections on "Great Lakes Landscape Change" and "Upper Mississippi River
Vegetation." The Great Lakes Landscape Change section draws on data
from three main sources (the fossil pollen record, Government Land
Office surveys and the U.S. Forest Service's Fourth Forest Inventory) to
assess changes during two time periods:
It includes a map of changes between presettlement and current
