Importance of salt marshes
Salt marshes are among the most productive ecosystems on earth. The plants in salt marshes survive on the minerals brought in but the tides, tides work as a two way street the bring in nurtrinets in for the plants and bring nurtrinets out for the fish. Over time, salt marshes accumulate organic material, forming into a dense layer called peat. Salt Marshes also slow the velocity of waves before they reach land and mitigate storm surges.
