[9] It was introduced in 1973 by the Army Corps of Engineers in an attempt to reclaim marshland, and was spread and replanted around the bay in further restoration projects. Spartina alterniflora Smooth cordgrass (Spartina alterniflora) dominates the low marsh habitats because it is more able to oxygenate its roots in reduced soils than saltmeadow cordgrass.

Contributions of recent barometric pressure trends to rates of sea level rise in southeastern Massachusetts (USA). It has been reclassified as Sporobolus alterniflorus after a taxonomic revision in 2014,[2] but it is still common to see Spartina alterniflora and in 2019 an interdisciplinary team of experts coauthored a report published in the journal Ecology supporting Spartina as a genus.

S. anglica has since spread throughout northwest Europe, and (following introduction for erosion control) eastern North America. An Extensive Study and Analysis of System Modeling and Interfacing of Vanadium Redox Flow Battery. Several means of control and eradication have been employed against Spartina alterniflora where it has become a pest. [4] It grows in a wide range of salinities, from about 5 psu to marine (32 psu), and has been described as the "single most important marsh plant species in the estuary" of Chesapeake Bay. It included both Spartina alterniflora and Spartina patens, smooth cordgrass and salt hay, the primary elements of Maine coastal marshes.

Zonation of Spartina patens and Spartina alterniflora in a New England salt marsh. In New England salt marshes the boundary between frequently flooded low marsh habitats and less frequently flooded high marsh habitats is characterized by striking plant zonation. This plant can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in different places, and some are listed above. 72(1): 138-148. Spartina alterniflora – U.S. Forest Service; Quick Facts. Palaemon vulgaris 44: 389–410. These results support the hypothesis that S. alterniflora is restricted to low marsh habitats by competitive displacement. [7], In Willapa Bay of Washington state, Spartina alterniflora was probably an accidental introduction during oyster transplants during the nineteenth century and may have dispersed from there to other parts of the state. Salinity and disturbance mediate direct and indirect plant–plant interactions in an assembled marsh community. Normally grows with Distichlis spicata. The hybrids also produce much larger numbers of fertile seeds than the native Spartina, and are producing a hybrid population that, left unchecked, can increase not only in population size but also in its rate of population growth. Spartina alterniflora monocultures dominate low marsh habitats while the seaward border of high marsh habitats is generally dominated by Spartina patens. Tidal flooding diminishes the effects of livestock grazing on soil micro-food webs in a coastal saltmarsh. var. The hybrids produce enormous amounts of pollen, which swamp the stigmas of the native S. foliosa flowers to produce even larger numbers of hybrid offspring, leaving the affected native Spartina little chance to produce unhybridized offspring. S. alterniflora thrives in anoxic low marsh habitats due to its ability to oxygenate its roots and rhizosphere. Callaway, J.C., and M. N. Josselyn. Duncan, Wilbur H.; Duncan, Marion B. Soil-geomorphology relationships and landscape evolution in a southwestern Atlantic tidal salt marsh in Patagonia, Argentina. Response and resilience of Spartina alterniflora to sudden dieback. This suggests that the success of S. alterniflora in anoxic habitats is size dependent and may be driven by group benefits of rhizosphere oxidation. Spartina alterniflora (Spartina) is the only halophyte in the salt marsh.However, the molecular basis of its high salt tolerance remains elusive. Plant distribution along an elevational gradient in a macrotidal salt marsh on the west coast of Korea. One example of an invasive Spartina alterniflora hybrid is that of Spartina anglica. Spartina alterniflora is well established in San Francisco Bay, and has had the greatest impact of all the cordgrasses in San Francisco Bay. Working off-campus?

Border of Spartina patens - Spartina alterniflora zone In the foreground we see the Spartina patens zone, which is higher (though that is hard to tell from the photo) than the S. alterniflora zone (taller grass in the background). Classification and environmental correlates of tidal wetland vegetation in Nova Scotia, Canada. Grows between the low- and high-tide marks in salt and brackish marshes, forming dense colonies that usually parallel the shoreline. King, C. Ferris, D. R. Ayres, and D. R. Strong. As of 2016, the infestation had been reduced to less than 3 solid hectares (7 acres). Rhizosphere oxidation by S. alterniflora, however, is not evident in seedlings and small colonizing patches and both seedlings and small colonizing patches of S. alterniflora are stunted in anoxic low marsh substrates. • CT, MA, ME, NH, RI.

Salt Marsh Aboveground Production in New England Estuaries in Relation to Nitrogen Loading and Environmental Factors. S. anglica has a variety of traits that allow it to outcompete native plants, including a high saline tolerance and the ability to perform photosynthesis at lower temperatures more productively than other similar plants. In Willapa Bay, leafhopper bugs (Prokelisia marginata) were employed to kill the plants, which threaten the oyster industry there, but this method did not contain the invasion.
