CEGL008433 Juncus effusus - Chelone glabra - Scirpus spp. Southern Blue Ridge Beaver Pond Ruderal Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Common Rush - White Turtlehead - Bulrush species Southern Blue Ridge Beaver Pond Ruderal Marsh
Colloquial Name: Southern Blue Ridge Ruderal Beaver Pond Marsh
Hierarchy Level: Association
Type Concept: This community occurs in beaver-impounded sites along mountain streams in the Southern Blue Ridge and Cumberland Mountains and Ridge and Valley physiographic provinces. Vegetative composition is highly variable, but Juncus effusus is a characteristic dominant. The physiognomy of the type is also extremely variable. Examples of this community range from no shrub cover to high levels of cover depending upon the amount of time since inundation and the fluctuation of the water level over time.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: As the beaver pond ages, the vegetation may quickly succeed into a shrubby version of this association, eventually becoming an Alnus- or Salix-dominated association. The variable communities of beaver marshes and meadows are poorly understood. This type may need substantial revision and clarification.

Physiognomy and Structure: No Data Available
Floristics: Composition is highly variable from place to place and time to time. Juncus effusus dominates. Other species may include Chelone glabra, Scirpus atrovirens, Scirpus hattorianus, Hypericum mutilum, Carex gynandra, Oxypolis rigidior, Ludwigia palustris, Mimulus ringens, Eleocharis spp., Thelypteris noveboracensis, Leersia virginica, Carex lurida, and Carex echinata.
Dynamics: These are very dynamic communities, changing as a result of alteration of water levels by beaver activity and dam washouts or abandonment. They undergo major successional transformations.
Environmental Description: This association is known from moderately high elevations of 610 to 915 m (2000-3000 feet) in the southern terminus of the Blue Ridge and Ridge and Valley physiographic provinces.
Geographic Range: The distribution of this type is poorly understood, since its circumscription is as yet unclear. It was originally defined from the southern terminus of the Blue Ridge and Ridge and Valley physiographic provinces.
