Discarded material could have resulted in the initial invasion of this species from the east to west coast of United States of America (Sayce, 1988). Spartina alterniflora or “smooth cordgrass” was introduced to the coast of mainland China in 1979 to promote conversion of tidal flats into dry land and has since spread rapidly.

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. In its native habitat, S. alterniflora is of great value (Landin, 1991; Simenstad and Thom, 1995). Journal of Aquatic Plant Management. In: The Proceedings of the Second International Spartina Conference, Olympia WA. Oecologia. Spartina glabra Proceedings of the New Zealand Ecological Society, 17:33-40.

Weed Pest Control Conf. was shown to be an ineffective sole biological control agent against S. alterniflora, achieving a density reduction in stems of 18.4%. USA. Higher stem densities dissipate more wave action, therefore allowing a larger amount of sediment to be deposited and a steeper beach profile to form (Gleason et al., 1979).

In addition, if large, dense populations of S. alterniflora are present around the mouth of an estuary, decreased flow may occur, leading to an increase in flooding likelihood, especially during sustained periods of heavy rainfall coinciding within above average tides (Ebasco Environmental, 1993). 33-40.

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. Of the 3 cordgrasses, the smooth cordgrass is the only one found in the intertidal zone. Mendelssohn IA, McKee KL, 1988.
