CEGL004307 Panicum hemitomon - Juncus spp. Coastal Plain Lakeshore Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Maidencane - Rush species Coastal Plain Lakeshore Marsh
Colloquial Name: Mid-Atlantic Coastal Plain Lakeshore Marsh
Hierarchy Level: Association
Type Concept: This association occurs on the shorelines of Coastal Plain lakes of northeastern North Carolina, as emergent or drawdown vegetation. The moderate to dense herbaceous vegetation is fairly diverse. Panicum hemitomon and a variety of other herbaceous species are abundant; Juncus militaris, Juncus effusus, Schoenoplectus americanus, Xyris smalliana, and Eriocaulon aquaticum may be abundant or dominant. Decodon verticillatus, emergent shrubs, or sparse Taxodium ascendens may also be present.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: More study is needed to clarify the variability within this type and to clarify its structure. Though sparse cypress trees may be present, it appears to best be described as herbaceous vegetation. However, it is closely related to other lake shoreline communities that are treated as woodlands. This association is meant to cover moderately diverse shoreline marsh communities, such as those at Lake Phelps in North Carolina. The more depauperate Panicum hemitomon beds with irregular cypress canopies in North Carolina are included in ~Taxodium distichum - Taxodium ascendens / Panicum hemitomon Swamp Woodland (CEGL004466)$$. The more diverse calcareous shoreline community of Lake Waccamaw is treated as ~Taxodium distichum - Taxodium ascendens / Panicum hemitomon - Sclerolepis uniflora Swamp Woodland (CEGL004465)$$.

Physiognomy and Structure: No Data Available
Floristics: This moderate to dense emergent herbaceous vegetation is dominated by Panicum hemitomon and a variety of other herbaceous species. Juncus militaris, Juncus effusus, Schoenoplectus americanus (= Scirpus americanus), Xyris smalliana, and Eriocaulon aquaticum may be abundant or dominant. Decodon verticillatus, emergent shrubs, or sparse Taxodium ascendens may also be present. Other species include Eleocharis cellulosa, Myriophyllum tenellum, Luziola fluitans, Sagittaria subulata, Hydrocotyle umbellata, Sacciolepis striata, and Cyperus spp.
Dynamics: Dynamic processes are not well-known. This community is subject to wave action and to seasonal fluctuations in water levels. It may respond to longer term rainfall cycles. The amount of Taxodium may depend on past logging and on rare regeneration opportunities during extreme droughts.
Environmental Description: This association occurs in shallow water or drawdown zones along the shorelines of large natural lakes in the mid-Atlantic Coastal Plain.
Geographic Range: This association is known only from northeastern North Carolina.
