MLRA 113 - Central Claypan Areas Illinois and Missouri 28,670 km2 (11,030 mi2)

Potential Natural Vegetation:
When this MLRA was settled, most of the level upland soils supported tall grass prairie vegetation characterized by big bluestem, indiangrass, prairie dropseed, and switchgrass. The present potential for natural vegetation on the level upland soils is unknown. Forests of post oak, swamp white oak, blackjack oak, and pin oak grow on poorly drained soils. White oak, shingle oak, black oak, hickory, white ash, basswood, sugar maple, elm, and walnut grow on the better drained soils. Silver maple, willows, cottonwood, sycamore, elm, pin oak, white oak, hickory, and ash grow on flood plains.
