And in the Gulf of California in Mexico, mangroves provide habitat for about 32 percent of the local fishery landings, an equivalent of 15,000 dollars per acre. 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. << /Type /Font However, because distinguishing a mangrove species is based upon physical and ecological traits rather than family lineage, scientists often differ in what they consider to be a true mangrove. In mature Rhizophora, the trunk of the tree is completely suspended above the water by the arcing stilt roots. Once a propagule reaches the northern edge of the range, it not only has to implant and grow, it must also successfully reproduce.
