Reference:
Midwestern Ecology Working Group...
Description:
This oak savanna (or barrens) on limestone and dolostone is found in the Ozark region of the United States. Stands occur on moderately steep to steep upper slopes of hills, ridges, and plains, and on steep slopes and bluffs along streams and rivers. Aspect can be in any direction. Soils are rapidly drained to well-drained, and very shallow to shallow (0-100 cm). The parent material is limestone, cherty limestone, or dolomite with bedrock at or near the surface. The tree canopy is very open, sometimes somewhat stunted or limby, and occasionally complex in pattern due to the bedrock influence. Typical tree canopy species include Quercus muehlenbergii, Fraxinus americana, and Juniperus virginiana. Shrubs may include Rhus aromatica, Frangula caroliniana (= Rhamnus caroliniana), Crataegus spp., or more rarely, Cotinus obovatus. Dominant ground layer species include Schizachyrium scoparium, Sorghastrum nutans, and Bouteloua curtipendula. Other characteristic species include Astragalus crassicarpus var. berlandieri (= Astragalus mexicanus), Galium arkansanum, Ophioglossum engelmannii, Polygala senega, Smilax bona-nox, and, in more western stands of the Springfield Plateau, Astragalus distortus, Berlandiera betonicifolia (= Berlandiera texana), and Erysimum capitatum.
