It is described as intolerant of shade.. It can grow on a wider range of sediments than other species of Spartina, and can survive inundation in salt water for longer periods of time. ) in the Minas Basin, Nova Scotia 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. Callaway, J.C., and M. N. Josselyn. The introduction and spread of smooth cordgrass (Spartina alterniflora) in South San Francisco Bay. It is the ONLY species that can be installed in salt marsh areas that flood every day. Grows 1 to 2 feet high; green in spring and summer, turns light brown in late fall and winter. The limited ability of S. patens to oxygenate its rhizosphere in anoxic soils appears to limit S. patens to high marsh habitats. invasion on the landscape succession of Yancheng coastal natural wetlands, China Hollow stems grow from 2 to 4 ft (0.6 to 1.2 m) tall.

Spartina alterniflora . Appearance: Hay-like grass found in the upper areas of the marsh. Microbial Communities in Salt Marsh Systems and Their Responses to Anthropogenic Pollutants. In contrast, S. alterniflora transplants were vigorously in the high and low marsh when buffered from neighbors, but were excluded from the high marsh in 2—3 yr when S. patens was present. Atlantic cordgrass. Spartina alterniflora is well established in San Francisco Bay, and has had the greatest impact of all the cordgrasses in San Francisco Bay. 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. Zonation of Spartina patens and Spartina alterniflora in a New England salt marsh. 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.

It included both Spartina alterniflora and Spartina patens, smooth cordgrass and salt hay, the primary elements of Maine coastal marshes. 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. P. affinis Spartina patens ates the boundary between S. patens and S. alterniflora (Bertness, 1991). 72(1): 138-148. S. anglica has since spread throughout northwest Europe, and (following introduction for erosion control) eastern North America. Species-specific enzymatic tolerance of sulfide toxicity in plant roots. © 2021 Ecological Society of America. Tidal flooding is associated with lower ectoparasite intensity in nests of the Saltmarsh Sparrow ( Abstract. 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). S. anglica is a fertile polyploid derived from the hybrid S.alterniflora × townsendii (S. alterniflora × S. maritima), first found when American S. alterniflora was introduced to southern England in about 1870 and came into contact with the local native S. maritima. Functional and ecophysiological traits of Halimione portulacoides and Sarcocornia perennis ecotypes in Mediterranean salt marshes under different tidal exposures. Sea-level rise and macroalgal blooms may combine to exacerbate decline in Spartina patens and Spartina alterniflora marshes. Seed and Foliage: 2" plugs in 50 cell trays in the Nursery: Short, salt tolerant grass found just above mean high tide. Ecology. 2000. 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. Groundwater controls ecological zonation of salt marsh macrophytes. Recommended Uses: Use as a shoreling stabilization plant on edges of sand beaches and saltmarsh. (20 to 50 cm) long and 1 to 8 in.

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. , Spartina alterniflora has also been found to hybridize with S. foliosa, producing offspring Spartina alterniflora × S. foliosathat may be an even greater threat than S. alterniflora by itself. 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. It has now been introduced in British Columbia, Do interspecific competition and salinity explain plant zonation in a tropical estuary?. S. patens is less salt tolerant than S. alterniflora. Salt Hay Grass (Spartina patens)Alternate common name: Saltmeadow Hay, Marsh Grass, Saltmeadow Cordgrass. 76(5): 777-780. Smooth cordgrass spreads rapidly by rhizomatous roots. Geographic Variation in Plant Community Structure of Salt Marshes: Species, Functional and Phylogenetic Perspectives.  The hybrids may also be able to fertilize themselves, which the native Spartina cannot do, thus increasing the spread of the hybrid swarm even further. Classification and environmental correlates of tidal wetland vegetation in Nova Scotia, Canada. Slight elevational differences between the plant populations exist. En California, cuatro especies de Spartina exóticas (S. alterniflora , S. densiflora, S. patens, S. anglica) fueron introducidas a la región de … S. alterniflora thrives in anoxic low marsh habitats due to its ability to oxygenate its roots and rhizosphere. S. alterniflora is native to the Atlantic coast of the Americas from Newfoundland, Canada, south to northern Argentina, where it forms a dominant part of brackish coastal saltmarshes. Meadows of S. alterniflora can crowd out native species, reducing biodiversity and altering the environment; as a result of S. alterniflora's growth, invertebrates that live in mud flats disappear as their habitat is overgrown, and in turn, food sources shrink for birds who feed on those invertebrates. For an availability please contact us by phone or e-mail. The dominant grass in the upper half of salt marsh intertidal zone. Spartina patens × Spartina pectinata → Spartina ×caespitosa A.A. Eat. 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. In this paper I examine the role of interspecific competition in maintaining this zonation pattern. A managed realignment in the upper Bay of Fundy: Community dynamics during salt marsh restoration over 8 years in a megatidal, ice-influenced environment. Modeling long‐term salt marsh response to sea level rise in the sediment‐deficient Plum Island Estuary, MA. It thrives in mucky soil in full sun. Phylogenetic relatedness, ecological strategy, and stress determine interspecific interactions within a salt marsh community. Microbial Community Composition and Extracellular Enzyme Activities Associated with Juncus roemerianus and Spartina alterniflora Vegetated Sediments in Louisiana Saltmarshes. Spartina alterniflora invasion drastically increases methane production potential by shifting methanogenesis from hydrogenotrophic to methylotrophic pathway in a coastal marsh. Populations of Spartina alterniflora, Spartina patens, Juncus roemerianus, Scirpus olneyi, and Distichlis spicata located in Graveline Bay marsh, Mississippi, are studied. _____ Spartina patens is now found in marshes of Benicia State Recreation Area. Genotypic diversity weakens competition within, but not between, plant species. The collections were taken using the block transfer system. 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 grass can hinder water circulation and drainage or block boating channels. It is not just our beloved Spartina alterniflora that has gotten a name change, though; all species that were before placed in the genus Spartina have now been reclassified to the genus Sporobolus. Inundation and salinity impacts to above- and belowground productivity in Spartina patens and Spartina alterniflora in the Mississippi River deltaic plain: Implications for using river diversions as restoration tools. 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. Zonation of emergent freshwater macrophytes: Responses to small-scale variation in water depth. Increased tolerance to organic xenobiotics following recent allopolyploidy in Spartina (Poaceae). Facilitation shifts paradigms and can amplify coastal restoration efforts. Invasive Species: Spartina alterniflora, Smooth Cordgrass. Hypsometry of Cape Cod Salt Marshes (Massachusetts, U.S.A.) and Predictions of Marsh Vegetation Responses to Sea-Level Rise.  Taller than either of the parent species, the hybrid provides good shelter to Ridgway's rail, an occasional roadblock to its eradication.. Environmental heterogeneity influences life‐form richness and species composition but not species richness of aquatic macrophytes in tropical coastal rivers. Resource competition model predicts zonation and increasing nutrient use efficiency along a wetland salinity gradient. The flowers are a yellowish-green, turning brown by the winter. The tide on the Maine coast where samples were collected has a spring range of about 12 feet. Zonation of Spartina patens and Spartina alterniflora in a New England salt marsh. However, even this species cannot tolerated continuous inundation with salt water - the water must drain off twice a day. Extent and degree of hybridization between exotic (Spartina alterniflora) and native (S. foliosa) cordgrass (Poaceae) in California, USA determined by random amplified polymorphic DNA (RAPDs). The effect of competition on Bacopa monnieri zonation in an temporarily open/closed tropical estuary. Spartina alterniflora is in full bloom here along the Georgia coast. Tidal flooding diminishes the effects of livestock grazing on soil micro-food webs in a coastal saltmarsh. and Distichlis spicata (L.) Greene on the other sides. A tide prediction and tide height control system for laboratory mesocosms. It has rhizoidal roots, which, when broken off, can result in vegetative asexual growth. ; Strong D.R. This suggests that the success of S. alterniflora in anoxic habitats is size dependent and may be driven by group benefits of rhizosphere oxidation. (Poaceae, saltmeadow cordgrass), Spartina alterniflora Loisel. Spartina patens (Aiton) Muhl. This means that saltmeadow cordgrass, one of our beautiful high marsh plants and previously known as Spartina patens, is now called Sporobolus pumilus. Tidal Suppression Negatively Affects Soil Properties and Productivity of Spartina densiflora Salt Marsh. Leaves are 8 to 20 in. As the marsh accretes, S. alterniflora moves still further out to form a new edge. Please check your email for instructions on resetting your password.  4.

While in the grass family, S. alterniflora loves wet soils and brackish salinities. Evol. Syst. Native. But don’t let the common name fool you, marsh grass or smooth cord grass is not like the species we use in our front yards. 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. The site is bounded on two sides by levees but adjoins natural salt marshes dominated by S. alterniflora, Spartina patens (Ait.) CHARACTERISTICS Slender, wiry leaves that recurve down toward the base giving a graceful, hay like appearance. Washington, DC 20036phone 202-833-8773email: [email protected] Several means of control and eradication have been employed against Spartina alterniflora where it has become a pest. Ammodramus caudacutus smooth cordgrass. Spartina alterniflora S. patens is native to the upper reaches of salt marshes along the Atlantic Seaboard and Gulf coast of the United States. 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. 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. ESA Headquarters1990 M Street, NWSuite 700 One example of an invasive Spartina alterniflora hybrid is that of Spartina anglica. , 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. S. alterniflora also rapidly invaded the high marsh in the absence of S. patens. Propagation: Availability: Native nurseries, Seed, Specialty providers Manipulating saltmarsh microtopography modulates the effects of elevation on sediment redox potential and halophyte distribution. 2004.

Burdick, David M. 1989. Retreating marsh shoreline creates hotspots of high-marsh plant diversity. Intraspecific variation in indirect plant–soil feedbacks influences a wetland plant invasion. 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. Muhl. Growth of Common Brackish Marsh Macrophytes Under Altered Hydrologic and Salinity Regimes. Nutrient Enrichment Alters Salt Marsh Fungal Communities and Promotes Putative Fungal Denitrifiers. Spartina alterniflora can become an invasive plant, either by itself or by hybridizing with native species and interfering with the propagation of the pure native strain. Species.
