Name: Quercus stellata - Quercus marilandica / Schizachyrium scoparium Interior Acidic Bedrock Scrub Alliance
Reference: NatureServe Biotics 2019
Description: Native grasses dominate stands of this alliance with scattered trees and shrubs, with <i>Quercus stellata</i> and <i>Quercus marilandica</i> being the most common trees, although <i>Quercus velutina</i> and <i>Juniperus virginiana var. virginiana</i> may often be present. <i>Andropogon virginicus, Danthonia spicata, Dichanthelium</i> spp., and <i>Schizachyrium scoparium</i> are the most abundant grasses. <i>Rhus aromatica, Smilax bona-nox, Smilax glauca, Toxicodendron radicans, Ulmus alata</i>, and <i>Vaccinium arboreum</i> make up the sparse to moderate shrub layer. Lichens (e.g., <i>Cladonia</i> spp.) and mosses are prominent on exposed rock. Stands of this alliance occur on exposed slopes and thin soil areas throughout its range in the central United States. The soil is absent to thin (0-40 cm) and somewhat rapidly to very rapidly drained. Exposed bedrock or fragments of parent material are common on or at the surface. Some associations are over various igneous materials, e.g., nepheline syenite in Arkansas. In Missouri, they occur on moderate to steep slopes of dissected drainages along major streams and mounds. Organic matter is low, and clay content can be quite high.
