Name: Acorus calamus Tidal Marsh
Reference: NatureServe Biotics 2019
Description: This is an association of tidal freshwater marsh dominated by <i>Acorus calamus</i> that occurs in fresh to oligohaline reaches of tidal rivers along the Atlantic Coast from Massachusetts to Virginia. This association is best developed in higher, irregularly flooded elevations within freshwater tidal marshes but can occur in areas with a wide tidal range. Substrate is generally fine-particled, but varies from silts and silty mucks to peats and sands. The setting within the tidal marsh tends to be poorly drained; tidal flooding is ponded and of longer duration than adjacent areas. <i>Acorus calamus</i> is dominant, generally comprising at least 50% cover, over extensive patches within the interior of high marshes. <i>Peltandra virginica</i> is a frequent associate. Other associated species are variable and can include <i>Bolboschoenus fluviatilis, Sagittaria latifolia, Polygonum punctatum</i>, and <i>Impatiens capensis</i>. Species that can occasionally occur include <i>Pontederia cordata, Zizania aquatica, Leersia oryzoides, Typha latifolia, Polygonum arifolium, Bidens coronata, Hibiscus moscheutos</i>, and other <i>Schoenoplectus</i> spp. <i>Murdannia keisak</i> has been noted in the southern portion of the range. <i>Acorus calamus</i> is conspicuously dominant in spring and early summer. Later in the season, culms tend to lodge and form mats and be overtopped by other species.
