CEGL004078 Schizachyrium scoparium - Sporobolus compositus var. compositus - Rudbeckia fulgida var. fulgida Wooded Grassland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Little Bluestem - Tall Dropseed - Orange Coneflower Wooded Grassland

Colloquial Name: Limestone Cliff Barrens

Hierarchy Level:  Association

Type Concept: This community occurs on ledges of Mississippian limestone in the Southern Cliff Section of Kentucky (222Eo). Dominant species include Schizachyrium scoparium, Sporobolus compositus var. compositus, Sporobolus clandestinus, Danthonia spicata, Carex eburnea, Liatris squarrulosa, Rudbeckia fulgida var. fulgida, Symphyotrichum oblongifolium, Stenaria nigricans, and Manfreda virginica. Other frequent species include Panicum flexile, Scleria triglomerata, Minuartia patula, Hypericum dolabriforme, Euphorbia corollata, Lespedeza spp., Galactia spp., Lithospermum canescens, Solidago sphacelata, Helianthus hirsutus, Verbesina virginica var. virginica, Silphium trifoliatum, Aquilegia canadensis, Euphorbia commutata, and Blephilia ciliata. This community is associated with Quercus muehlenbergii - Quercus spp. forest in which the subcanopy may be dominated by Juniperus virginiana (this being regarded as a symptom of fire suppression). See ~Quercus muehlenbergii - Quercus (shumardii, stellata) / Cercis canadensis / Viburnum rufidulum Forest (CEGL007699)$$ in ~Quercus muehlenbergii - Acer saccharum - Fraxinus americana Forest Alliance (A2060)$$.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: The correct alliance placement of this association is uncertain. Rudbeckia truncata Small, regarded as a distinct entity by some workers (J. Campbell pers. comm. 1995), is treated here as Rudbeckia fulgida var. fulgida (Kartesz 1999). "This is associated with Juniperus - Quercus spp. Woodland and ~Rhus aromatica - Celtis tenuifolia / Carex eburnea Cliff Shrubland (CEGL004393)$$, with little or no fire influence; I do not believe fires had significant influence on these very rocky clifftop and ledge habitats before settlement" (J. Campbell pers. comm. 2001).
