Shallow or Rocky Prairie
An upland soil less than 20 inches deep and often very rocky and
rough but less than 20 percent slope. Gentle sloping to moderately steep shallow prairie soils. The site
contains combinations of forbs, legumes, grasses, and some shrubs. Rock usually appears on the sur-face,
often over 15 to 20 percent of the area, and occurs in the profile. The site occurs along ridges or
ledges, often adjacent to loamy or clay prairie sites. The vegetation was formed under migratory grazing
and heavy impact from bison and other native wildlife, with fires in both the dormant and growing
season.
