made in the finger-fill canal in phases I and II, 

 respectively, and 40 Sr of the transplants made 

 in the control bed (Tables 1 and 2). Transplant 

 attempts made with burlap in phase I were not 

 included in the above percentages because all 

 failed within 1 month. 



FiGUKE 4. — Details and treatment of sprigs anchored 

 by pipe, brick, and construction rod; and placement of 

 transplants at planting sites. 



Plugs in phase I planted July 1966 were re- 

 moved from the sites late in August 1967, ap- 

 proximately 13 months after planting. Six of 

 the 40 transplants at the canal area and 16 of 

 the 40 at the control area were successful 

 (Table 1). 



Planting individual sprigs of turtle grass in 

 phase II yielded similar results. Of the 60 

 sprigs planted in the second canal in April 1967 

 and removed in mid-October 1967 (about 6 

 months after they were transplanted), 11 were 

 successful (Table 2).

EROSION CONTROL 



Results of planting plugs within concrete- 

 block enclosures were completely different in 

 the finger-fill canal and grass bed locations 

 (Table 1). In the canal the only successful 

 transplants grew within the protection of the 

 block enclosures; none planted without this pro- 

 tection survived, and most of the latter failed 

 within the first 6 months of the experiment. 

 Most of the successful plugs placed in the con- 

 trol area were planted outside the concrete 

 blocks and, throughout the study, appeared to 

 be in better condition than those inside the en- 

 closures. The enclosures fulfilled their purpose 

 in the canal but ai)i)eared detrimental in the 

 control area. In the latter region, surrounding 

 grass beds apparently provided suflicient pro- 

 tection from water movement. Enclosures in
