Central Forest-Grasslands Transition
The Central forest-grasslands transition are a prairie ecoregion of the central United States, a portion of the North American Great Plains.
This is a great area that covers 157,000 square miles from central Illinois through the majority of Missouri, eastern Kansas, Oklahoma and into Texas. This region was conventionally a mixture of woodland and tall grass prairie, which as the soil is made up of highly fertile mollisols; most of the region has been transformed to farmland. The rainfall fluctuates from 600 to 1,040 millimeters per year and the region is vulnerable to fire and drought.
