dunes. Elevational profiles were made periodically in tlie test plots from April 1970 to 

 November 1977. The study concluded that sand fences initially capture sand more rapidly 

 than newly planted beachgrass. Once estabhshed, however, beachgrass plantings capture 

 sand at a rate equivalent to multiple lifts of sand fence. Using either sand fence or 

 beachgrass, a dune growth rate of more than 11 cubic meters per hnear meter of beach per 

 year was sustained.

Benthic communities adjacent to a restored beach at HaUandale (Broward County), 

 Florida, were analyzed and compared to equivalent communities in nearby Golden Beach 

 (Dade County). Five sand stations and four reef stations were sampled at each locality along 

 a transect extending from the intertidal zone through the second reef. The primary purpose 

 of tliis study was to assess the postnourishment condition of soft bottom- and reef-dweUing 

 bentlios approximately 7 years after dredging. The study also provides prenourishment data 

 for future impact analysis of a fiU project underway (late 1979) at HaUandale. 



Core samples at S£ind stations yielded 114 invertebrate species, not including 

 nemerteans and ohgochaete anneUds. More than 90 percent of the fauna occurred at the two 

 outer stations in densities up to 17,144 individuals per square meter. Quadrat samples of 

 reef biota showed a maximum abundance and diversity of corals, alcyonarians, and sponges 

 in tlie middle and outer regions of the second reef. The reefs appeared to be in good 

 condition, and showed no apparent effects of tlie 1971 beach nourishment project. It is 

 recommended that aU future beach renourishment projects be closely monitored by 

 quaUfied marine scientists.

 An intensive review was made of the historical and present work on transplanting 

 seagrasses, including eelgrass, turtle grass, shoalgrass, manatee grass, and ditch grass. The best 

 seasons, recommended methods of transplanting, and propagules to use for each species are 

 listed for tlie coasts of the United States. Some of the more important environmental 

 parameters which directly influence successful transplanting are reviewed.
