Puccinellia were planted at one of these freshly oiled sites (Fig. 42). 

 Cover and survival data determined 1 year later indicate no noticeable 

 effect of the oil on either species (Table 12, Fig. 43) as compared to 

 these data from transplants at unoiled sites which were planted the 

 same year (Table 9). As in many other experiments, cover data 

 indicated a significant transplant response to fertilizer materials 

 with best growth realized in the Osmocote slow release treatment.

 generally less than 50 cm 2 ; that of a Puccinellia plug was ca. 25

Creek Bank Plantings 



Creek banks with no vegetation cover are one of our top priority 

 planting sites. Preliminary plantings of Halimione made in May 1980 

 (Fig. 44) achieved over 90% survival and good growth by the following 

 May (Fig. 45). Puccinellia plantings have also achieved good survival 

 and growth over this period of time (Figs. 46, 47). About half of the 

 over 4,900 May 1981 transplants were planted along creek banks (Fig. 

 20). A similar proportion of the overall planting effort is planned 

 for creek bank sites in May 1982.
