Originally from the Atlantic coast, the grass works well at maintaining banks and tidal flats, but in China, it began to spread uncontrollably and is now taking over the mangrove forests. mangrove food web are driven by detritus (Spalding 2010).

The wood is frequently used to build stilt houses, furniture, fences, bridges, fishing poles and traps, canoes, rafts, and boats. Moreover, mangroves rely on mud buildup from rivers to help them make the transition, but studies suggest that in at least some parts of the world, mud isnt building up fast enough compared to the rate of sea level rise.
