The Midwestern Tallgrass bioregion, located in the Northern America (Nearctic) realm, is the third major section of the continent’s Great Plains subrealm, extending eastward from the Missouri River, where it transitions to open forests across Illinois, known as the central grassland-forest transition. 

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.
