G557 Andropogon glomeratus - Juncus effusus Ruderal Marsh, Wet Meadow & Shrubland Group

Type Concept Sentence: These ruderal herbaceous and shrub wetlands tend to be dominated by Andropogon glomeratus, Juncus effusus, and exotic plant species, such as the exotic shrub Ligustrum sinense or exotic grasses Pennisetum purpureum or Arundo donax. Included here are wetlands disturbed by vehicles or equipment.


Common (Translated Scientific) Name: Bushy Bluestem - Common Rush Ruderal Marsh, Wet Meadow & Shrubland Group

Colloquial Name: Southeastern Ruderal Marsh, Wet Meadow & Shrubland

Hierarchy Level:  Group

Type Concept: These are herbaceous wetlands which are characterized by ruderal conditions or dominance by exotic plant species. Also included here are wetlands which may have been severely disturbed by vehicles or equipment, such as coastal plain depressions which have been subjected to intensive forest management (i.e., bedded and site-prepped) and ponds used by recreational off-road vehicles. These ruderal herbaceous and shrub wetlands tend to be dominated by Andropogon glomeratus, Juncus effusus, and exotic plant species, such as the exotic shrub Ligustrum sinense or exotic grasses Pennisetum purpureum or Arundo donax.

Diagnostic Characteristics: Andropogon glomeratus and Juncus effusus are typical native graminoid species which are found in ruderal wet meadows and marshes. These are herbaceous wetlands which are characterized by ruderal conditions or dominance by exotic plant species. Examples would include wetlands dominated by the exotic grasses Pennisetum purpureum or Arundo donax. Also included here are wetlands which may have been severely disturbed by vehicles or equipment, such as coastal plain depressions which have been subjected to intensive forest management (i.e., bedded and site-prepped) and ponds used by recreational off-road vehicles.

Physiognomy and Structure: These are herbaceous wetlands which are characterized by graminoid or forb vegetation. The vegetation can include low shrubs as well.

Floristics: Andropogon glomeratus and Juncus effusus are typical native graminoid species which are found in ruderal wet meadows and marshes. This group also includes wetlands dominated by the exotic grasses Pennisetum purpureum or Arundo donax. Exotic shrub-dominated wetland vegetation is also included here, such as Ligustrum sinense- and Tamarix spp.-dominated vegetation. This does not include tall shrubs such as Triadica sebifera. Also, there is ruderal vegetation dominated by annual plants in open canopy flood zones which are exposed and even dry during the summer. This includes drawdown zones of reservoirs and other wetland habitats. Broadleaf exotic emergent wetland plants are also included here, including Colocasia esculenta wetland vegetation.

Dynamics:  These wetlands are subject to natural disturbances, such as flooding or hurricanes. Many sites have been subjected to anthropogenic disturbance or are dominated by invasive exotic plants.

Environmental Description:  Wetlands, which may occur along rivers and creeks, or on extensive flats, or in depressions. Climate: Warm temperate. Soil/substrate/hydrology: Generally the vegetation is on hydric soils. Sites have often been disturbed, either from natural processes, such as flooding, or anthropogenic actions. Due to their aggressive nature, the dominant species in this group do not require disturbance to remove native species before invading an area.

Geographic Range: This group occurs in the south-central and southeastern United States from North Carolina to Florida, west to Tennessee, Arkansas, Louisiana and Texas.
