The article focuses on the pattern of invasion and the quantitative estimate of change of Spartina townsendii from the mudflats of Poole Harbour in England. The interest in the type of grass is discussed, including its origin, unusual habitat, and possible uses in reclamation and protection of coastal mudflats in the country. The early collections of Spartina species were composed entirely of a plant with sterile stamens. Moreover, a cytological investigation gives corrected chromosome numbers for the different types of grasses.

The article presents a study that investigates the ecological condition of tidal submergence and chlorinity in Spartina salt marshes in Poole Harbour, England. In the study, samples were collected from three different areas within Poole Harbour where fresh water and sea water meet and mix and manifest evidences of swarding and surface scour erosion as well as by observing its tidal submergence level. The study reveals that tidal submergence factor is essential in suppressing Spartina growth with a maximum height of six inches during active period and can withstand nine hours of tidal submergence with high chlorine tolerance.
