Abstract:

Experimental plantings to stabilize eroding shorelines in Bogue Sound in 1974 were successful. Better stands were produced on sites subject to severe wave stress by reducing transplant spacing to 1.5 to 2 feet apart. Rhizomes without well-developed culms attached were worthless as propagules within the intertidal zone. Seeding was unsuccessful due to exposure to excessive wave energy. Some of the adaptation of Spartina alterniflora to the low oxygen supply and the ammonium form of nitrogen characteristics of the intertidal zone were confirmed by laboratory studies. Plants were detrimentally affected by forced aeration of roots and the substitution of nitrate for ammonium. Stands of Spartina alterniflora continued to respond to high inputs of nitrogen and phosphorus through the fourth year.
