Name:
Spartina patens - Schoenoplectus (americanus, pungens) - (Distichlis spicata) Salt Marsh
Reference:
NatureServe Biotics 2019
Description:
This represents brackish marsh vegetation (mesohaline) of the Gulf Coast of Texas, Louisiana, Mississippi and Alabama. <i>Spartina patens</i> dominates in this rarely flooded high marsh zone. Other species that may be present in variable amounts include <i>Distichlis spicata, Juncus roemerianus, Vigna luteola, Typha</i> spp., <i>Phragmites australis, Spartina alterniflora, Lythrum lineare, Lythrum alatum var. lanceolatum, Cyperus articulatus, Kosteletzkya virginica, Spartina cynosuroides</i> (within its range), <i>Paspalum vaginatum, Borrichia frutescens, Baccharis halimifolia, Schoenoplectus americanus, Schoenoplectus pungens, Bolboschoenus robustus, Ipomoea sagittata</i>, and <i>Eleocharis parvula</i>. This zone grades down into vegetation dominated by <i>Juncus roemerianus</i> or <i>Spartina alterniflora</i>, and up into shrub-dominated zones or saline prairie. The woody shrub component of this zone is diminished by storm tides, as well as the effects of fire. Longer fire intervals have led to greater encroachment of shrubs. In coastal Louisiana and Texas, this is a common, very brackish marsh type, often interspersed with ~<i>Spartina alterniflora - Distichlis spicata - Spartina patens</i> Mesohaline Salt Marsh (CEGL002230)$$. It is found in both the Deltaic and Chenier plains of Louisiana. More information is needed on this vegetation type. Composition and relative dominance vary considerably from the Deltaic Plain to the Chenier Plain and Coastal Plain of Texas.
