Savannah, Ga. – Georgia’s salt marshes contribute greatly to the coastal environment, from providing a nursery for young marine life to serving as a buffer from storm surges. But is there a way to put a dollar value on a salt marsh? As the University of Georgia Skidaway Institute of Oceanography continues its year long 50th anniversary celebration with monthly public science programs, Dr. Bill Savidge will examine the economic value of the “goods and services” that salt marshes provide to the citizens of the Georgia coast. The Evening @ Skidaway program, “What is a salt marsh worth?” will be presented on Tuesday, March 13, in the McGowan Library on the University of Georgia Skidaway Marine Science Campus. (10 Ocean Science Circle, Savannah, GA 31411) The event will begin with a reception at 6:15 p.m., followed by the program at 7 p.m. The program is open to the public, and admission is free. Space is limited.
