Dunes Hold It All Together
It is easy to understand how the lower beach (below the hide tide line) is especially prone to erosion from waves, however, areas above the high tide line known as the dune also suffer from disturbance by wind and invasive plants. Not only is the dune area important habitat to nesting sea turtles, it is also a vital source of replacement sand for the lower beach. Dunes have special salt-tolerant vegetation like railroad vine and sea oats pictured below. These plants can tolerate wind, salt, and lack of freshwater while at the same time collect and hold sand, like a reservoir for future sand needs.
To date, ERM has overseen the enhancement of 100 acres of dunes.
