CEGL002147 Quercus stellata - Quercus marilandica / Schizachyrium scoparium Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Post Oak - Blackjack Oak / Little Bluestem Woodland
Colloquial Name: Crosstimbers Post Oak - Blackjack Oak Woodland
Hierarchy Level: Association
Type Concept: This post oak - blackjack oak woodland type is found in the southeastern Great Plains and tallgrass prairie areas, sometimes called the Crosstimbers region, of the United States. Stands are found on ridgetops and gently to steeply sloping hillsides. Soils are shallow to moderately deep, sandy to loamy, and somewhat poorly drained to well-drained. The parent material is typically sandstone. The vegetation structure is an open canopy of trees. Dominant species include Quercus stellata and Quercus marilandica, with occasional Quercus prinoides and Celtis tenuifolia. The shrub layer is often absent. The ground layer consists of Schizachyrium scoparium, Andropogon gerardii, and Sorghastrum nutans.

Classification Comments: Type has been described in the Crosstimbers region of Kansas and Oklahoma by Küchler (1974). Distinctions between the forest type, ~Quercus stellata - Quercus marilandica - (Carya texana) Forest (CEGL002074)$$, and this woodland type need review. ~Quercus stellata - Quercus marilandica - Quercus velutina - Carya texana / Schizachyrium scoparium Woodland (CEGL002149)$$ occurs further east in the Ozarks.
