2Q. ABSTT^ACT (Xoirttoue ant rmvwrmm at^a ft rrmc^aaary mad Identity by block number) 



A simplified, low-cost transplanting technique has been developed for 

 seagrasses, Ualodule wvightii and Sy ring odium filiforme, for use in high- and 

 low-current regimes. The method makes use of mature, vegetative shoots, free 

 of sediment and anchored to the substrate. The technique accounts for selection 

 of planting stock, species growth rate, and depth of planting site for estimat- 

 ing the design, labor, and material requirements of a transplant. Examples are 

 provided to illustrate use of the tables and formulas for computing the neces- 

 sary requirements.
