CEGL004047 Leersia hexandra - (Panicum verrucosum, Scleria reticularis) Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Southern Cutgrass - (Warty Panicgrass, Netted Nutrush) Marsh
Colloquial Name: Small Depression Pond (Cutgrass Prairie Type)
Hierarchy Level: Association
Type Concept: This depression pond type covers examples which are typically found in small, flat Carolina bays or other depressions with loamy soils and a hydroperiod slightly shorter than other marsh types. The stands of vegetation are dominated by or have a substantial component of Leersia hexandra. The vegetation varies dramatically in response to rainfall cycles. In wetter periods, Leersia hexandra dominates more strongly, while in drier times Panicum verrucosum and Scleria reticularis are also abundant. In long droughts, Panicum hemitomon and various woody species may invade.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The Cutgrass Prairie Type is distinguished by the dominance or codominance of Leersia hexandra during wet periods and a continued substantial presence of it during droughts. This type should generally not be classified in the same depression as other emergent types. Nifong (1998) emphasized the successional relationships between the three of his associations that are included in this type, suggesting that they are different phases that can occur in the same site at different times in normal climatic cycles.
