Name:
Spartina pectinata Interior Prairie Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance covers graminoid vegetation dominated by <i>Spartina pectinata</i>. Associates in Kentucky and Tennessee occurrences may include <i>Andropogon gerardii, Agalinis fasciculata, Asclepias tuberosa, Baptisia alba var. macrophylla, Cephalanthus occidentalis, Crotalaria sagittalis, Dichanthelium clandestinum, Dichanthelium scoparium, Helianthus angustifolius, Helianthus grosseserratus, Helianthus mollis, Heterotheca villosa, Rhexia mariana, Rudbeckia hirta, Rudbeckia subtomentosa, Schizachyrium scoparium, Sorghastrum nutans, Spiranthes cernua, Tripsacum dactyloides</i>, and <i>Viola sagittata</i>. Examples are found in open, wet (saturated to seasonally flooded) areas in Arkansas, Kentucky, and (probably) adjacent Tennessee. <i>Spartina pectinata</i> is a very wide-ranging species and this alliance is near the southern limit of its largely midwestern range. This southeastern alliance is represented by small disjunct occurrences in the Upper West Gulf Coastal Plain of Kentucky, possibly extending a short distance into adjacent Tennessee, and related areas of Arkansas. These areas can remain saturated for much of the growing season, but can experience droughty conditions in the summer and fall. In Kentucky, this vegetation is at present probably seasonally saturated; it was presumably formerly seasonally flooded.
