Prairie Grassland Biome

By: Taylor Zehm

Grasses

Porcupine grass (Hesperostipa spatrea), Little blue stem (Schizachyrium scorparium), Big Bluestem (Andropogon geradii), and Indian Grass (Sorghastrum nutans) are the dominant plant life in the prairies. These plants thrive in moderately wet to dry soil conditions. The picture to the right shows Porcupine grass.

Glacier Impact

Once the great glacial lakes receded from these prairie grasslands, the soil went in two distinct directions. The hills are found to be made of gravel, and the great expanses of rolling prairie are composed of a base layer of sand from old, large, rivers. These fields are also home to very rich black dirt that was favored by early settlers. A small portion of this biome is heavy in mineral rich soil, this makes for standing water to be commonplace.
