Spartina spartinae Saline Marsh Alliance | NatureServe Biotics 2019

Name: Spartina spartinae Saline Marsh Alliance Reference: NatureServe Biotics 2019 Description: This alliance occurs in near-coastal areas along the Gulf Coast of Texas and possibly Louisiana and the Mexican state of Tamaulipas. These saline coastal prairies are dominated by <i>Spartina spartinae</i> and occur in poorly drained areas in the vicinity of the coast, but they are isolated from tidal influence, except during extreme storm events. This alliance occurs on "upland" flats often forming a band, a mile or more in width, between tidal marshes and the more upland nonsaline coastal prairie. It also occurs in microtopographic depressions within the nonsaline coastal prairie matrix. <i>Spartina spartinae</i> may be the sole dominant, or it may share dominance with other grasses, such as <i>Schizachyrium littorale, Schizachyrium scoparium var. scoparium</i>. <i>Schizachyrium scoparium</i> may be locally abundant. Other species include <i>Andropogon glomeratus var. pumilus, Paspalum vaginatum, Spartina patens, Cyperus</i> spp., <i>Palafoxia texana var. ambigua</i>, and <i>Eupatorium serotinum</i>. This alliance has been previously placed in upland, but predominant soils are Natraqualfs, and these soils are saturated to the surface for periods of the growing season. <i>Spartina patens</i> is sometimes locally codominant. The hydrology of this alliance is ambiguous, exhibiting qualities of both seasonally flooded and saturated.  Accession Code: urn:lsid:vegbank.org:commConcept:38182-{24BE68CC-61F5-44D0-8453-7938632D69D2} Plot-observations of this Community Concept: 0
