CEGL004199 Spartina spartinae - Sporobolus virginicus Tidal Salt Marsh

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Gulf Cordgrass - Seashore Dropseed Tidal Salt Marsh

Colloquial Name: Gulf Coast Irregularly Flooded Tidal Salt Marsh

Hierarchy Level:  Association

Type Concept: This community occupies relatively irregularly tidally flooded situations along the Gulf of Mexico from Texas to the Florida Keys. Spartina spartinae is dominant. Other species present can include Sporobolus virginicus, Suaeda linearis, Batis maritima, Borrichia frutescens, Agalinis maritima, Spartina patens, Symphyotrichum tenuifolium, Limonium carolinianum, Cynanchum angustifolium, Distichlis spicata, and Sabatia stellaris within its range. Some examples may be codominated by Sporobolus virginicus. In the Florida Keys, these sites are affected only by highest non-storm tides, and have pore water salinities about 20 ppt. Soils are deep (greater than 30 cm), fine-textured mineral soils. On the panhandle Florida coast this community occurs in small stands, usually in lower areas behind a beach ridge on the bayshore side of barrier islands.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Range of the nominal species is along the Gulf of Mexico coast from eastern Mexico to the Florida Keys (Hitchcock and Chase 1971). Similar vegetation from the southern tip of Texas, characterized by some subtropical components, is classified as ~Spartina spartinae - Monanthochloe littoralis - Suaeda linearis Salt Marsh (CEGL004614)$$.

Physiognomy and Structure: No Data Available

Floristics: This association is usually dominated by Spartina spartinae. Other salt-tolerant herbs can include Sporobolus virginicus, Suaeda linearis, Batis maritima, Borrichia frutescens, Agalinis maritima, Spartina patens, Symphyotrichum tenuifolium (= Aster tenuifolius), Limonium carolinianum, Cynanchum angustifolium, Distichlis spicata, and Sabatia stellaris within its range. Some examples may be codominated by Sporobolus virginicus.

Dynamics:  No Data Available

Environmental Description:  This association is infrequently tidally inundated and tends to develop somewhat hypersaline conditions. In the Florida Keys, this type is found in supratidal environments affected by only the highest non-storm tides; pore water salinities are consistently above 20 ppt, and soils are "deep (greater than 30 cm), fine-textured mineral soils" (Ross et al. 1992). This type is relatively uncommon in the Keys where it is apparently confined to the center of a few mud islands in Florida Bay, along two peninsulas extending into the Gulf, and in a narrow zone above supratidal scrub in the lower Keys.

Geographic Range: This association ranges around the northern Gulf of Mexico from Texas to the Florida Keys. It is known from the Gulf Coast of Panhandle Florida at Crooked and Shell islands (Bay County) and Alligator Point (Franklin County) (A. Johnson pers. obs.) and Point au Pins, Mobile County, Alabama.
