TL;DR: Wang et al. as mentioned in this paper introduced four species of Spartina (Spartina anglica, S.alterniflora and S.cynosuroides) to China from England in 1963 and from the United States in 1979, respectively.

TL;DR: The current status of the natural wetlands in China is described, past problems are reviewed, the funding of billions of dollars to restore degraded wetlands, and the national plan to place 90% of natural wetlands under protection by 2030 are reviewed.

TL;DR: Under various sedimentation environments, the clonal spread efficiency of seedlings was higher than that of vegetative offspring, and there is a positive feedback relationship between sedimentation and the growth of S. alterniflora .

TL;DR: Evaluating relative competitive ability using the Relative Neighbour Effect (RNE) index and the growth responses of the two species under both independent and mixed planting experiments suggests a mechanism by which S. alterniflora has been able to replace S. anglica and quickly invade the natural salt marsh communities of coastal China.

TL;DR: High plant density might be one of the important factors in the dieback of S. anglica, which is surviving at high density along the Chinese coast and has a much lower growth rate due to strong intraspecific competition, and because high-density populations may decline into low density populations due to resource exhaustion.
