CEGL005240 Sagittaria latifolia - Leersia oryzoides Marsh

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Broadleaf Arrowhead - Rice Cutgrass Marsh

Colloquial Name: Arrowhead - Rice Cutgrass Marsh

Hierarchy Level:  Association

Type Concept: This arrowhead marsh type is found in the midwestern United States mostly along larger floodplains such as the upper Mississippi River and its larger tributaries. Stands occur in semipermanently flooded wetlands dominated by Sagittaria latifolia and/or Leersia oryzoides. In examples of this type, Leersia oryzoides typically occurs in more shallow areas or where the water recedes enough to allow it to establish, but not inhibit, Sagittaria latifolia. Other emergent aquatic species such as Potamogeton spp. and Ceratophyllum demersum are also often present. Although this type can occur naturally, many examples along major waterways can be impacted by dams and/or impoundments. Examples of this community may become monospecific stands of either Sagittaria latifolia or Leersia oryzoides, especially in areas above dams along major rivers where the environment can be more lacustrine in nature. More information is needed to determine the range of this type outside of the upper Midwest.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: This type can occur naturally but many examples, especially areas of monospecific or nearly monospecific stands, may be caused by dams or impoundments. Separating natural occurrences from semi-natural ones may be difficult, especially on rivers that have been permanently altered due to dams. Also, this type could be considered a subtype of a more broadly defined shallow marsh type, ~Schoenoplectus tabernaemontani - Typha spp. - (Sparganium spp., Juncus spp.) Marsh (CEGL002026)$$.
