Protectors of the Dunes
Sea oats help protect
Amelia's beaches
Newcomers to Amelia Island are always impressed by the beauty of the sea oats growing on the primary dunes along the oceanfront. But this hearty grass (Uniola paniculata) performs a
far more important function than adding its good looks to the scenery. It helps to hold the sand and protect the dunes from wind and erosion.
Since sand dunes are so dry, a 6-inch sea oats plant may have roots which are five feet long. This long root system helps stabilize the dunes against erosion. In addition, the plant above ground can catch windblown sand to increase the size of the dune.
So important are the sea oats that Florida law prohibits the picking of them at any time. Driving on the dunes is also prohibited. Also, people are urged to use boardwalks when walking over the dunes in an effort to preserve the beach-protecting sea oats.
