CAREX TORTA TEMPORARILY FLOODED HERBACEOUS ALLIANCE (A.1340)TWISTED SEDGE TEMPORARILY FLOODED HERBACEOUS ALLIANCEALLIANCE CONCEPTSummary: This alliance includes sedge-dominated alluvial wetlands on sand, gravel, and rock bars in valleys and gorges in thesouthern Appalachians, ranging west into the Cumberland Plateau and Interior Low Plateau, and north into central Appalachians andAllegheny Mountains. Associations in this alliance are characterized by light-demanding, tough-rooted herbaceous perennials tolerantof frequent inundation and flood-scouring. Carex torta often forms dense, extensive colonies. Associated species vary withgeography. In the Allegheny Mountains, associated species include Doellingeria umbellata (= Aster umbellatus), Dichantheliumclandestinum, Solidago rugosa ssp. aspera, Juncus effusus var. solutus, Scirpus expansus, Scirpus cyperinus (= var. pelius),Equisetum arvense, Onoclea sensibilis, Vernonia noveboracensis, Lycopus virginicus, Scutellaria lateriflora, and Salix sericea. Insouthern Appalachian gorges this vegetation often is associated with Alnus serrulata - Xanthorhiza simplicissima Shrubland(CEGL003895). In the Cumberland Plateau of Alabama, herbaceous components may include Lobelia cardinalis, Symphyotrichumdumosum (= Aster dumosus), Lycopus virginicus, Osmunda regalis, and Hypericum mutilum.Related Concepts:• IIE3a.
