Name: Isoetes riparia - Eriocaulon parkeri Intertidal Freshwater Marsh Alliance
Reference: NatureServe Biotics 2019
Description: This alliance represents freshwater tidal vegetation dominated by the characteristic species <i>Eriocaulon parkeri</i> and <i>Isoetes riparia</i>. Associated species may include <i>Cyperus bipartitus, Elatine minima, Eleocharis obtusa, Isoetes riparia, Sagittaria calycina</i>, and <i>Sagittaria subulata</i>. In more muddy areas, <i>Schoenoplectiella smithii</i> occurs. Some of this vegetation is restricted to areas that receive substantial scour during spring floods, since <i>Eriocaulon parkeri</i> is very susceptible to siltation. The vegetation can be quite sparse, with few plants growing in patches within the open sand. This alliance is found in coastal areas from North Carolina north to Maine, and possibly Canada. Examples occur on sandy or gravelly shores that are exposed only at low tide, such as on the upper limits of freshwater intertidal shores.
