Name: Sagittaria latifolia - Leersia oryzoides Marsh
Reference: NatureServe Biotics 2019
Description: 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 <i>Sagittaria latifolia</i> and/or <i>Leersia oryzoides</i>. In examples of this type, <i>Leersia oryzoides</i> typically occurs in more shallow areas or where the water recedes enough to allow it to establish, but not inhibit, <i>Sagittaria latifolia</i>. Other emergent aquatic species such as <i>Potamogeton</i> spp. and <i>Ceratophyllum demersum</i> 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 <i>Sagittaria latifolia</i> or <i>Leersia oryzoides</i>, 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.
