A3412 Juncus effusus - Andropogon glomeratus var. pumilus - Saccharum giganteum Ruderal Marsh Alliance

Type Concept Sentence: These disturbed marshes and other open wetlands of the southern and eastern United States are dominated by native grasses and grasslike plants, such as Andropogon glomeratus var. pumilus, Saccharum giganteum, Scirpus cyperinus, Juncus effusus, Typha spp., and have few or no trees.

Common (Translated Scientific) Name: Common Rush - Bushy Bluestem - Giant Plumegrass Ruderal Marsh Alliance

Colloquial Name: Southern Ruderal Graminoid Marsh

Hierarchy Level:  Alliance

Type Concept: These disturbed marshes and other open wetlands are dominated by native graminoid plants, and have few or no trees. These areas may be dominated by Andropogon glomeratus var. pumilus, Juncus effusus, Saccharum giganteum, Scirpus cyperinus, Typha spp., or other graminoid plants. This alliance is found in the southern and eastern United States, from Maryland and West Virginia, south to Florida and Texas. This vegetation occurs in disturbed wetland sites, such as old fields (particularly old fields in bottomlands), as well as low areas and ditches in old fields.

Diagnostic Characteristics: Southeastern graminoid semi-natural wetland vegetation dominated by native graminoid plants, including disturbed marshes.

Physiognomy and Structure: The vegetation is characterized by native graminoid plants, with few or no trees.

Floristics: Stands of this vegetation type may be dominated by Andropogon glomeratus var. pumilus, Juncus effusus, Saccharum giganteum, Scirpus cyperinus, Typha spp., or other graminoid plants, with few or no trees.

Dynamics:  This semi-natural vegetation occurs on disturbed wetland sites, such as bottomland old fields, or cutover bottomlands where trees or shrubs have not become dominant again.
Environmental Description:  This vegetation occurs in disturbed wetland sites, such as old fields. In Louisiana, this vegetation can dominate old fields in bottomlands. In Texas, this vegetation may dominate low areas and ditches in old fields in the Gulf Coast Prairies and Marshes.
Geographic Range: This alliance is found in the southern and eastern United States, from Maryland and West Virginia, south to Florida and Texas.
