Juncus effusus Marsh
Translated Name: Common Rush Marsh
Common Name: Common Rush Marsh
Unique Identifier: CEGL004112
Classification Approach: International Vegetation Classification (IVC)
Summary: This broadly defined type represents freshwater marsh vegetation dominated by Juncus effusus. Additional types may be developed as more information becomes available. This vegetation may occur in natural or artificial ponds, including beaver-enhanced ones. In various parts of its broad range as currently defined, associated species may include Andropogon glomeratus, Cyperus spp., Typha latifolia, Scirpus cyperinus, Triadenum walteri, Apios americana, and Galium aparine. This type includes seasonally to temporarily flooded vegetation dominated or codominated by Juncus effusus in the Central and Southern Appalachians.



Classification

Classification Confidence: Moderate
Classification Comments: A new association is likely to be split from CEGL004112 to represent northeastern expressions of the community as new data become available.

Though this association was not seen at the Bankhead National Forest, it is expected to occur there.


Vegetation Hierarchy
Class 2 - Shrub & Herb Vegetation
Subclass 2.C - Shrub & Herb Wetland
Formation 2.C.4 - Temperate to Polar Freshwater Marsh, Wet Meadow & Shrubland
Division 2.C.4.Nd - Eastern North American Temperate & Boreal Freshwater Marsh, Wet Meadow & Shrubland
Macrogroup Eastern-Southeastern North American Ruderal Marsh, Wet Meadow & Shrubland
Group Southeastern Ruderal Marsh, Wet Meadow & Shrubland
Alliance Southern Ruderal Graminoid Marsh

This is the revised vegetation hierarchy. For more information see Classification Sources and usnvc.org.

Vegetation

Vegetation Summary: This type is currently broadly and literally defined, based on dominance by Juncus effusus. In various parts of its broad range as currently defined, associated species may include Andropogon glomeratus, Carex spp., Cyperus spp., other Juncus spp., Typha latifolia, Scirpus cyperinus, Triadenum walteri, Apios americana, and Galium aparine. In Georgia, Wharton (1978) cites Carex rostrata, Carex stipata, Schoenoplectus pungens (= Scirpus americanus), and Sagittaria latifolia as associates of beaver pond vegetation containing Juncus effusus.
