SPARTINA REVEGETATION ON DREDGE SPOIL IN SE MARSHES

Spoil from the dredging of harbors, rivers, and the Inland Waterway when deposited on salt marshes often permanently destroy these important natural resources. Portions of destroyed marsh can be restored through transplantation of the major marsh plant Spartina alterniflora. This was accomplished in a typical silt-clay spoil site along the Intra-coastal Waterway in Georgia for less than $100/acre. Thirty percent of the transplants survived and are continuing to spread 18 months after planting. Elevation of the spoil is of prime importance for transplants and at lower elevations survival rates are as high as 75%. The use of seeds and nursey grown seedings was not as successful; only 13% of the seeds germinated and none of the seedlings survived.
