The establishment and development of seedling transplants for shoreline erosion abatement are reported for Spartina alterniflora within the intertidal zones and for Spartina patens, Spartina cynosuroides, Distichlis spicata, and Ammophila breviligulata within the supratidal zones, of a dredged-material site and three sandy shore sites in the mid-Chesapeake Bay region. No limitations were found for plant establishment above mean high water MHW at the experimental sites. The net production of Spartina alterniflora transplants in moderate to low-energy sandy areas was increased between 135 and 860 by periodic applications of fertilizer. Macrobenthic invertebrate invasion and colonization of the sterile dredged-material area was slow, but after 11 months the number of individuals per square meter between MHW and 15 centimeters below mean low water MLW was statistically greater than those at nearby natural and manmade tidal sandflat areas.
