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)$$.

Environmental Description: Stands occur in semipermanently flooded wetlands.
Geographic Range: This type is found in the midwestern United States. Its range outside of major rivers in the upper Midwest needs further review.
