The ability of this species to trap large volumes of tidal sediments led to its deliberate introduction in several parts of the world (North Europe, Australia, New Zealand, China...) in conjunction with land reclamation. However, the rapid expansion of the invasive species is now considered to be a threat to coastal environments (Daehler & Strong, 1996; Ayres et al., 2004; Chen et al., 2004). S. alterniflora have become model organisms for studying biological invasions from both ecological and genetic perspectives (Blum et al., 2004). The invasive mechanism of the species became involuntarily a researching hotspot.
