It contains three ecoregions – Central US Forest-Grasslands Transition (387), Central Tallgrass Prairie (388), Flint Hills Tallgrass Prairie (392) – and incorporates the western half of Lake Michigan as well as a large section of the Missouri River. 

The total land area of this bioregion is nearly 60 million hectares.

The Midwestern Tallgrass Prairie & Forest Transition bioregion is part of the Great Plains subrealm and is made up of three ecoregions: (1) Flint Hills Tallgrass Prairie (2) Central Tallgrass Prairie (3) Central US Forest-Grasslands Transition.
