1.They are the nurseries of the oceans. Many species may spawn there and many other species may live portions of their lives in estuaries.
2.The higher salinity of an estuary helps protect some young creatures from predators.
3.Estuaries, especially mangrove areas really do a lot of cleansing. Mangrove leaves start to decay on the tree before they fall off. Once they hit the water they
break down and are the basis of many marine food chains. Thus they are one of the most beneficial systems.
4.Grass flats also produce food. At any one time, there could be millions of tons of sea-grasses floating on the gulf stream or settling on reefs all along the east coast. Fuelling many food webs.
5. They are the cradle of the sea, and the most fragile areas too. Just one storm-water project 50 years ago, has been determined to have killed 4 bays at the mouth of this watershed. Too much freshwater upset the delicate balance of the salinity in the estuaries and they "died".
