Propagation of Spartina alterniflora for Substrate Stabilization and Salt Marsh Development.
NORTH CAROLINA STATE UNIV RALEIGH
Pagination or Media Count:
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. Transplants 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, more plant cover was produced from seeding at the rate of 100 viable seeks per square meter than from transplanting single-stem plants on a 0.9-meter spacing.
