Dormant seeds do not survive longer than one year (Woodhouse, 1979). The table below shows the average S. alterniflora density reductions achieved by various control methods. Within the appendix of their 2006 report, they summarise the individual results of each disparate study and combine these within a meta-analysis to establish the most efficacy control method and attempt to obtain variables (e.g. ), saltwort (Batis spp. Prog., San Francisco Bay Estuary Proj. ©Fred Weinmann/Bugwood.org - CC BY-NC 3.0 US. Before S. alterniflora was present, Pacific Northwest estuaries consisted of bare, gently sloping mud flats with shallow tidal channels. Mullins PH, Marks TC, 1987. Based on bird usage and sediment softness, tilling appears to restore mudflats back to suitable habitat for foraging shoreline birds (Gross-Custard and Moser, 1988). The roots also slow the movement of tidal waters, causing sediments to settle out of the water and build up the muddy bottom. The movement of Spartina is prohibited in most states of USA. There are also some economically beneficial uses for S. alterniflora. Another impact of increased sediment accretion is the resultant change in water circulation patterns. 16 (4), 826-832. Sheaths mostly glabrous, throat glabrous or minutely pilose, lower sheaths often wrinkled; ligules 1-2 mm; blades to 60 cm long, 3-25 mm wide, lower blades shorter than those above, usually flat basally, becoming involute distally, abaxial surfaces glabrous, adaxial surfaces glabrous or sparsely pilose, margins usually smooth, sometimes slightly scabrous, apices attenuate. Martinsville, VA, USA: Virginia Museum of Natural History. Trin. We found little evidence for the evolution of genetic clines in China, even though these exist for some traits in the native range. This means that the introduction of S. alterniflora to an estuary or coastline can occur via either natural spread, due to tidal conditions or via human induced actions such as shipping (ballast water) or intentional planting (e.g. Mount Vernon, Washington, USA: Washington State Department of Ecology. Special report No. Differences in MTR among marsh locations accounted for 70 and 68% of the statistical variation in the upper and lower limits, respec- tively, of S. alterniflora growth.

During the first 50 years, the population slowly expanded, but from 1945 to 1988 the plant became established throughout the bay, forming vast meadows (Sayce, 1988). Population variation in growth response to flooding of three marsh grasses. Environmental Toxicology & Chemistry, 17(10):1972-1978.

However, Cohen and Carlton (1995) have suggested that the earliest report of S. alterniflora occurred around 1911, suggesting that solid ballast material is the most likely transport mechanism.

Plant species diversity in these wetlands is extremely rich, and many of thousands of acres have been diked, drained, and farmed. However, ground sprayed glyphosate did significantly reduce S. alterniflora density, with treatment dates of June/July applications of 38 kg ae/ha being more effective than either similar concentrations at different times of the year or lower active ingredient concentrations. Panicles 10-40 cm, with 3-25 branches, often partially enclosed in the uppermost sheath; branches 5-15 cm, loosely appressed, not twisted, more or less equally subremote to moderately imbricate throughout the panicle, axes often prolonged beyond the distal spikelets, with 10-30 spikelets. In Puget Sound, WA, S. alterniflora was introduced to stabilize coastlines and increase the vegetative cover of mudflats to reduce wave impact. Panicles 10-40 cm, with 3-25 branches, often partially enclosed in the uppermost sheath; branches 5-15 cm, loosely appressed, not twisted, more or less equally subremote to moderately imbricate throughout the panicle, axes often prolonged beyond the distal spikelets, with 10-30 spikelets. We compared the growth, salt tolerance, and osmotic adjustment of M haplotype P. australis and S. alterniflora along a salinity gradient in greenhouse experiments. 58 (1/3), 140-148. http://www.sciencedirect.com/science/journal/00988472 DOI:10.1016/j.envexpbot.2005.07.006, CABI, Undated.

In: The Proceedings of the Second International Spartina Conference, Olympia WA. Patten K, 2004. Does exotic Spartina alterniflora change benthic invertebrate assemblages? 6. There is some concern that vertical growth or accretion of salt marshes may not be able to keep pace with accelerated rates of sea level rise, resulting in submergence or drowning of marshes. Management of the S. alterniflora is expensive and time consuming, early prevention of invasion is recommended prior to its establishment. Once tillered, hand-pulling may break off portions of the root, allowing the plant to re-grow. Increases in nutrient supply convert swards of the short form of Spartina alterniflora into plants tending to resemble the tall form, in biomass/m 2 and in general morphology. Finally, in 1988, an Everglades mesocosm with both salt and fresh marshes was established in a greenhouse in Washington, DC. Stalter, R. 1973. The marshes exhibit a striking zonation of emergent plants. 221-231. USA. Spartina is a relatively small genus consisting of approximately 14 species, geographically centered along the east coast of North and South America, with outliers on the west coast of North America, Europe, and Tristan da Cunha.

While methionine is transaminated to form 4-methylthio-2-oxobutyrate in algae, it is methylated first to form S-methyl methionine and then converted to dimethylsulfoniopropionaldehyde (DMSP-ald) by some mechanism. However, we have adopted the taxonomic interpretation of Cabrera (1970) that this species is synonymous with Spartina brasiliensis Raddi and Spartina maritima var. 82 (10), 2830-2845.

In arid and semiarid regions where precipitation is low and evaporation is high, salinity of floodwaters may exceed that of seawater, which is 35 parts per thousand (ppt). Hedge P, Kriwoken LK, Patten K, 2003. Roberts and Pullin (2006; 2007) have, using systematic review and meta-analysis, extensively reviewed the efficacy of the control methods available for S. alterniflora. One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. Spartina alterniflora (Smooth Cordgrass) is a species of marsh grass native to the Atlantic and Gulf coasts of the United States, where it is considered a valuable plant making important contributions to the coastal ecology: Its dense growth provides protection against storm surge and “erosion control along shorelines, canal banks, levees, and other areas of… Flowering phenology and seed production of Spartina anglica. Irrespective of the initial means of introduction, the plant was not accurately identified until 1940s, when the plants flowered (Scheffer, 1945; Sayce, 1988). brasiliensis (Raddi) St. Yves. From all the data captured for herbicide application, imazapyr, had the greatest impact in chemically controlling S. alterniflora densities (85% density decline). Otherwise, no significant difficulties were encountered. Roman, in Encyclopedia of Ocean Sciences, 2001. This tangle of roots allows the trees to handle the daily rise and fall of tides, which means that most mangroves get flooded at least twice per day. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. The density reductions achieved by the herbicides are included in the table of control measures. Thom R, Cordell J, Simenstad C, Luiting V, Borde B, 1997. On the Atlantic coast of North America, Spartina alterniflora is the early colonizer and almost exclusively dominates the low marsh. Fiddler crabs facilitate Spartina alterniflora growth, mitigating periwinkle overgrazing of marsh habitat Rachel K. Gittman. Furbish C E, Albano M, 1994.

Each spikelet contains one seed (Moberley, 1956; Daehler and Strong, 1994). Variable reproductive output among clones of Spartina alterniflora (Poaceae) invading San Francisco Bay, California: the influence of herbivory, pollination, and establishment site. China's booming economy is sparking and accelerating biological invasions. Gaps in Knowledge Res. Sporobolus virginicus is a cosmopolitan grass, and an important component of lower and upper midlittoral zones in gaps of the mangrove canopy or midtidal flats (Santos, 1989). Smooth cordgrass, Spartina alterniflora, of the US Atlantic coast, forms monotypic stands in the low marsh, where inundation by the astronomical tides occurs twice daily. C.T.
