Update on Coastal Marsh Dieback in Georgia Prepared for GA DNR – Coastal Resources

Since 2001, patches of dying vegetation have been observed in Georgia marshes, generally during periods of dry or drought conditions. These events are collectively referred to as salt marsh dieback. Salt marsh dieback is characterized by the thinning and browning of Spartina alterniflora and other marsh grasses which eventually leads to plant death. This is a concern because salt marsh habitat is extremely important in the life cycles of crabs, fish, and shrimp, and it also provides food for many wildlife species. In addition, salt marshes help prevent or lessen local flooding.
