Spartina alterniflora, a close relative of S. densiflora, is much more effective at trapping sediment and raising mudflat or marsh elevations, and has been introduced in China and other locations to reclaim land and protect against flooding (Wan et al. Each plant produces a tough rhizome (roots) system.
