CEGL006616 Panicum virgatum - (Andropogon virginicus) Ruderal Meadow

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Switchgrass - (Broomsedge Bluestem) Ruderal Meadow

Colloquial Name: Ruderal Upland Switchgrass Meadow

Hierarchy Level:  Association

Type Concept: This herbaceous community is found on dry sandy soils in abandoned agricultural fields and along roadsides from coastal Massachusetts to Maryland. Diagnostic features include the dominance of Panicum virgatum in an upland environmental setting. Panicum virgatum is the dominant species, but Andropogon virginicus may be codominant. Other species may include Conyza canadensis, Tridens flavus, Rhexia mariana, Juncus tenuis, Helenium autumnale, Ageratina altissima, Sorghastrum nutans, and Dichanthelium clandestinum. Solidago rugosa, Rumex acetosella, and Anthoxanthum odoratum are associates documented from Massachusetts. Scattered shrubs including Morella pensylvanica are often present.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This type is distinguished, in theory, from the very similar ~Dactylis glomerata - Phleum pratense - Festuca spp. - Solidago spp. Ruderal Meadow (CEGL006107)$$ and ~Schizachyrium scoparium - (Andropogon virginicus) - Solidago spp. Ruderal Meadow (CEGL006333)$$ by the dominance of Panicum virgatum. Additional data will be required to see how this distinction holds up and what geographic differences might accompany such a distinction.
