This photo says it all.   By placing the Reef Balls along the shoreline to create an oyster reef,  the shoreline was protected and the marsh grasses are now stabilizing the shore and province a great place for carbon sequestration.   Not to mention the EFH, and all other crustaceans  doing their part to improve the Gulf of Mexico.
