Land Use History of North America
examines how we have used land since the 1700s and how the land has changed. Topics include population settlement and farmland, urban sprawl and soil resources, flora species, urbanization in the Baltimore-Washington corridor, landcover changes in the Great Lakes region, vegetation along the upper Mississippi River, biodiversity in the Yellowstone ecosystem, and landscape changes in the Southwest.

Interesting Fact:
The landscapes of the Great Lakes region incorporate dynamic interactions between the grasslands of the Great Plains, the eastern deciduous forests, and the boreal forests of North America. Patterns of climatic circulation give this region remarkably varied climate despite the fairly uniform topography. |
