Name:
Typha domingensis - Schoenoplectus spp. - Sagittaria subulata Tidal Salt Marsh Group
Reference:
NatureServe Biotics 2019
Description:
Brackish tidal marshes develop where saltwater mixes with freshwater, primarily in estuaries but also sometimes on the lee side of barrier islands or in other settings. The vegetation is primarily herbaceous, but there may be areas of shrub dominance. Graminoids are prominent and typically include tall species such as <i>Typha angustifolia, Typha domingensis, Schoenoplectus americanus, Schoenoplectus pungens, Bolboschoenus robustus</i>, and <i>Spartina cynosuroides</i>. The salt marsh grasses <i>Spartina patens</i> and <i>Spartina alterniflora</i> may also be present, but generally are mixed with other species instead of exhibiting strong dominance as they do in the salt marsh setting. Those <i>Spartina</i> are typically most abundant where brackish marsh is transitioning to salt marsh, for example at the estuary mouth. Some brackish tidal marshes are forb-dominated; common species in these settings include <i>Sagittaria subulata, Limosella australis, Lilaeopsis chinensis, Sagittaria calycina var. spongiosa, Polygonum arifolium, Polygonum hydropiperoides, Zannichellia palustris, Eleocharis parvula</i>, and <i>Amaranthus cannabinus</i>. Some of these forbs also occur as associates where graminoids are dominant.<br /><br />In Atlantic Canada, the brackish marshes have a somewhat different character. They are characterized by <i>Carex paleacea, Hierochloe odorata, Juncus arcticus ssp. littoralis, Spartina pectinata</i>, and/or <i>Schoenoplectus maritimus/pungens</i>; <i>Solidago sempervirens</i> is frequent; freshwater species, such as <i>Typha latifolia, Typha angustifolia, Solidago uliginosa</i>, among others, are typical; <i>Carex mackenziei, Cladium mariscoides, Eleocharis parvula, Hordeum jubatum, Limosella australis, Samolus valerandi</i>, and <i>Teucrium canadense</i> may be present. Coastal plain species such as <i>Schoenoplectus americanus, Eleocharis rostellata</i>, and <i>Lilaeopsis chinensis</i> (more typical in low salt marsh) are only found in western Nova Scotia.
