Typha angustifolia remained present in the tidal fresh water part of this system, following its original stocking; however, it was never dominant, probably because of the small space and interference by other species. Control of smooth cordgrass with Rodeo® in a southwestern Washington estuary. S. alterniflora was also introduced to Thorndyke Bay, Kala Point, and Sequim Bay to increase vegetative cover (Ebasco Environmental, 1992). were similarly established with ease. Within its introduced range a concern is being raised over S. alterniflora impact to habitats where present due to its ability to reduce tidal energy and trap sediment. Expansion rates and recruitment frequency of exotic smooth cordgrass, Spartina alterniflora (Loisel), colonizing unvegetated littoral flats in Willapa Bay, Washington. determining factor for growth and productivity for S. alterniflora in Louisiana salt marshes. In its native habitat, S. alterniflora is of great value (Landin, 1991; Simenstad and Thom, 1995). Glumes straight, sides usually glabrous, sometimes pilose near the base or appressed pubescent, hairs to 0.3 mm; lower glumes 4-10 mm, acute; upper glumes 8-14 mm, keels glabrous, lateral veins not present, apices acuminate to obtuse, occasionally apiculate; lemmas glabrous or sparsely pilose, apices usually acuminate; paleas slightly exceeding the lemmas, thin, papery, apices obtuse or rounded; anthers 3-6 mm. Biological control of Spartina alterniflora in Willapa Bay, Washington using the planthopper Prokelisia marginata: agent specificity and early results. In the past few decades, Spartina alterniflora has become one of the dominant species in the coastal wetlands in China due to its unique physiological and ecological characteristics (e.g., higher growth rate, higher net primary yield, and higher salt tolerance) compared to native plants [13,14]. 4. Optimizing the efficacy of glyphosate to control Spartina alterniflora. 2. are also documented in Australia, New Zealand, China, France, the Netherlands and United Kingdom. No experimental trials of combining cutting and smothering are reported for control of S. alterniflora. and Phragmites australis Cav. The loss of habitat for bivalves is of particular concern in Willapa Bay, WA, as it supports a US$16 million oyster industry. Daehler CC, Strong DR, 1995. Within its native habitat, S. alterniflora roots and shoots are a food source for waterfowl and wetland mammals, partly keeping the expansion of Spartina wetlands in check.

Redfield's classic study of salt marsh development along a coast with a rising sea level, salt marshes often extend seaward over tidal flats, while also accreting vertically and encroaching the upland or freshwater tidal wetlands. Effects of stem density upon sediment retention by salt marsh cord grass, Spartina alterniflora Loisel. As a result, it was widely planted at coastal sites throughout the UK, Northern Europe, Australia, New Zealand, China and USA, where it has naturally colonized (via seed or vegetative fragments) large areas of tidal mudflats, becoming an invasive species.

USA. have a dense root/rhizome system that binds coastal mud and its sturdy stem decreases wave action allowing silt deposition, causing elevation of the mudbank, assisting in land reclamation. Pollen germinated about 15 min after contacting the stigma, and pollen tubes grew to the micropyle within 55 to 75 min. A tall form occurs along creek banks and drainage channels. Management of the S. alterniflora is expensive and time consuming, early prevention of invasion is recommended prior to its establishment.

It also has the capacity to tolerate a wide range of environmental conditions, including: inundation up to approximately 12 hours a day, pH levels between 4.5and 8.5 and salinity levels of 10-60 ppt, although 10-20 ppt allows for optimal growth (Landin, 1991). Environmental gradients and herbivores feeding preferences in coastal salt marshes. Spartina alterniflora has become one of the dominant species in the coastal wetlands in China due to its unique physiological and ecological characteristics (e.g., higher growth rate, higher net primary yield, and higher salt tolerance) compared to native plants [13,14]. 509-521. 1, Lingxuan Meng.

Plant species and patterns of vegetation that dominate the salt marsh vary from region to region of the world and it is beyond the scope of this article to detail this variability; however, the general pattern of low marsh and high marsh remains throughout. Covell CV, 2005. Early in the development, halophytes, such as Spartina alterniflora along the east coast of the United States, colonize intertidal flats.

Salt marsh vegetation, including Spartina, Distichlis, Batis maritima, Sporobolus virginicus, and others, often is found growing with mangroves. The marshes exhibit a striking zonation of emergent plants. After nearly a century of expansion the initial infestation in Willapa Bay spread to a maximum extent of 3500 hectares in 2003.

Report to Washington Dept. Ecology. 267-274. Spartina alterniflora (smooth cordgrass); infestation of densely packed plants on a mudflat. Using a close relative of S. alterniflora as a guide, sediment accretion associated with S. anglica infestations in England, has been reported to reduce tidal flow (Hubbard, 1965). Bascand LD, 1970. Spartina patens, Distichlis spicata, Juncus gerardi, Juncus roemerianus, and short-form Spartina alterniflora occupy the US east coast high marsh, with each species dominating in patches or zones to form a mosaic vegetation pattern.

Exploring environmentally friendly, economic and effective techniques for controlling Spartina alterniflora is of great significance for the management of coastal wetlands. Biological Invasions, 6:221-231. 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.

The density reductions achieved by the herbicides are included in the table of control measures. Ecology. Control of S. alterniflora densities with glyphosate gave a combined density reduction of around 59%. However, further investigation is required to see if integrating it with another control measure would increase its efficacy of controlling S. alterniflora. NH4+ supply influences the allocation of C resources between rhizomes and shoots (Haines and Dunn, 1976; Rogers et al., 1998; Valiela et al., 1976). Multiple years of application only marginally increased the herbicides effectiveness, however if a years application is missed then reduction in density drops below 50%. Systematic Review No. 3.
