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. Like its relative saltmeadow cordgrass S. patens, it produces flowers and seeds on only one side of the stalk. Groundwater controls ecological zonation of salt marsh macrophytes. Native. What if we let it? [11] The hybrid can physically modify the environment to the detriment of native species,[12] and the hybrid populations have spread into creeks, bays, and more remote coastal locations. Do interspecific competition and salinity explain plant zonation in a tropical estuary?. Spartina alterniflora . Herbivory drives zonation of stress‐tolerant marsh plants. Vegetation Dynamics in Rhode Island Salt Marshes During a Period of Accelerating Sea Level Rise and Extreme Sea Level Events. Growth of Common Brackish Marsh Macrophytes Under Altered Hydrologic and Salinity Regimes. [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. An Extensive Study and Analysis of System Modeling and Interfacing of Vanadium Redox Flow Battery. An Experimental Evaluation of Dock Shading Impacts on Salt Marsh Vegetation in a New England Estuary. Saltmarsh rhizosphere fungal communities vary by sediment type and dominant plant species cover in Nova Scotia, Canada. Resource competition model predicts zonation and increasing nutrient use efficiency along a wetland salinity gradient. Intraspecific variation in indirect plant–soil feedbacks influences a wetland plant invasion. 72(1): 138-148. These results suggest that the maintenance of intertidal zonation in rocky beach and marsh plant communities is very similar. Relative Importance of Biotic and Abiotic Forces on the Composition and Dynamics of a Soft-Sediment Intertidal Community. It is the ONLY species that can be installed in salt marsh areas that flood every day.

Habitat edge effects decrease litter accumulation and increase litter decomposition in coastal salt marshes. Recommended Uses: Use as a shoreling stabilization plant on edges of sand beaches and saltmarsh. S. alterniflora grows in tallest forms at the outermost edge of a given marsh, displaying shorter morphologies up onto the landward side of the Spartina belt. These results support the hypothesis that S. alterniflora is restricted to low marsh habitats by competitive displacement. It thrives in mucky soil in full sun. 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. Competition does not explain the absence of a carnivorous pitcher plant from a nutrient-rich marsh. 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. It can grow in low marsh (frequently inundated by the tide) as well as high marsh (less frequently inundated), but it is usually restricted to low marsh because it is outcompeted by salt meadow cordgrass in the high marsh. Number of times cited according to CrossRef: Barnacle colonization on Spartina alterniflora in Georgia salt marshes.

It has now been introduced in British Columbia, Significant alteration of both marsh composition and structure due to the establishment of invasive Spartina, and especially Spartina alterniflora and its hybrids, can be observed around the San Francisco Estuary. Phylogenetic relatedness, ecological strategy, and stress determine interspecific interactions within a salt marsh community. Self-organization of a biogeomorphic landscape controlled by plant life-history traits. It grows out into the water at the seaward edge of a salt marsh, and accumulates sediment and enables other habitat-engineering species, such as mussels, to settle. King, C. Ferris, D. R. Ayres, and D. R. Strong. (20 to 50 cm) long and 1 to 8 in. Facilitation shifts paradigms and can amplify coastal restoration efforts. Sporobolus alterniflorus, or synonymously known as Spartina alterniflora, the smooth cordgrass,[1] saltmarsh cordgrass, or salt-water cordgrass, is a perennial deciduous grass which is found in intertidal wetlands, especially estuarine salt marshes. Ammodramus caudacutus smooth cordgrass. The caterpillars of Aaron's skipper (Poanes aaroni) have only been found on this species to date. The tide on the Maine coast where samples were collected has a spring range of about 12 feet. S. alterniflora is a dominant species that helps to stabilize the ecosystem, retain a seedbank of other species, uptake nutrients, and provide important habitat for wildlife. Spartina alterniflora x S. foliosa Photo courtesy Joseph DiTomaso. In this paper I examine the role of interspecific competition in maintaining this zonation pattern. S. alterniflora is noted for its capacity to act as an environmental engineer. 72(1): 138-148. 1992. At its peak of infestation in 2003, it covered approximately 3,000 solid hectares (more than 8,500 acres), spread across an area of 8,000 hectares (20,000 acres). Inspired by colorful Daufuskie Island, South Carolina, Spartina 449 is carried in more than 1,500 specialty retail and boutique shops nationwide and abroad. This is not the variety that would grow in/on the water, though it is salt tolerant and normally can sustain salt water inundation 3-4 times per year (rather than daily as is the case with Spartina Alterniflora).

Smooth cordgrass is a perennial grass that is native to the Atlantic and Gulf Coasts of North America but is invasive along the Pacific Coast. 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. Patterns and environmental drivers of greenhouse gas fluxes in the coastal wetlands of China: A systematic review and synthesis. In this study, we used Pacific Biosciences (PacBio) full-length single-molecule long-read sequencing and RNA-seq to elucidate the transcriptome dynamics of high salt tolerance in Spartina by salt gradient experiments. The world’s largest invasion of Spartina alterniflora is in China, where plants from multiple North American locations were intentionally planted starting in 1979 with the intention of providing shore protection and sediment capture. If we ever need Spartina Patens (high marsh grass), they have thousands of plugs ($.35 per plug) and lots of seed. Species-specific enzymatic tolerance of sulfide toxicity in plant roots. Syst.

Spartina alterniflora Our native plant nursery also has many other species available throughout the year. _____ Spartina patens is now found in marshes of Benicia State Recreation Area. Mangroves dramatically increase carbon storage after 3 years of encroachment. Spartina patens, the saltmeadow cordgrass, also known as salt hay, is a species of cordgrass native to the Atlantic coast of the Americas, from Newfoundland south along the eastern United States to the Caribbean and northeast Mexico.It has been reclassified as Sporobolus pumilus after a taxonomic revision in 2014, but Spartina patens is still in common usage. Modeling long‐term salt marsh response to sea level rise in the sediment‐deficient Plum Island Estuary, MA. Hand pulling is ineffective because even small rhizome fragments that inevitably break off and get left in the soil are capable of sending up new shoots.

[13] Taller than either of the parent species, the hybrid provides good shelter to Ridgway's rail, an occasional roadblock to its eradication.[14]. Proceedings of the National Academy of Sciences. Spartina patens turfs and tillers transplanted into the low marsh were severely stunted with or without S. alterniflora neighbors, and low marsh bare patches bordering S. patens monocultures were not significantly colonized by S. patens in three growing seasons. 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. In California, four species of exotic Spartina (S. alterniflora, S. densiflora, S. patens, and S. anglica) have been introduced to the San Francisco Bay region. ; Garcia-Rossi D.; Davis H.G.
