Techniques were developed for propagation of Spartina alterniflora 

 Loisel., smooth cordgrass, in the intertidal zone on dredge spoil and eroding 

 shorelines. Both seeding and transplanting methods were successful. Trans- 

 plants proved to be more tolerant of rigorous conditions such as storm waves 

 and blowing sand, but seeding was more economical and was successful on 

 protected sites. Vegetative development of seeded and transplanted areas 

 was rapid with primary production equal to that of a long established marsh 

 by the second growing season. At the end of the first growing season,
