spring or summer transplants would have a higher survival rate. In 
the lower zone it is of questionable value because of low survival 
during the early spring period. 
j. Big cordgrass. This cordgrass species did not survive at any 
of the planting dates in the upper zone (Table 18). Survival in the 
middle zone occurred at each planting date, except April. However, the 
survival rates were about 3 percent or less, regardless of planting date. 
Vegetative reproduction was approximately seven tillers per surviving 
transplant in January and March plantings (Table 19). Reproduction was 
slightly less for May and was reduced to one for the July planting. 
Big cordgrass transplants did not survive in the lower zone, regardless 
of planting date. 
This species is not adapted for use in clay-loam shoreline stabili- 
zation. Survival did not occur in either the upper or lower zones. In 
the middle zone survival rate was erratic and low. 
k. Gulf cordgrass. This species is the dominant plant of the 
vegetative cover in the upper zone. Thus, efforts were not made to 
establish transplants. In the middle zone, gulf cordgrass survived at 
all planting dates, except May (Table 18). Survival ranged from a low 
of about 1 percent in January to over 8 percent in July. Even though 
this species survived, it did not vegetatively reproduce (Table 19). 
Gulf cordgrass survived in only the May planting in the lower zone. 
The surviving transplants did not vegetatively reproduce. 
This species does provide good cover and forage in the upper zone. 
However, results to date, indicate it is of little or no value in either 
the middle or lower zones. 
1. Saltcedar. This introduced species of widespread occurrence 
has been difficult to establish by cuttings along the shoreline. Salt- 
cedar survived in only the January and April plantings in the upper 
zone (Table 18). Survival was less than 7 percent and vegetative re- 
production did not occur (Table 19). Survival of less than 2 percent 
was recorded for January and July plantings in the middle zone. 
Vegetative reproduction was not observed. This species did not 
survive in the lower zone, regardless of planting date. 
3. Zonation. 
The objectives of the planting studies were to determine planting 
dates and species adaptation by zones along East Bay. Thus, by orienting 
rows perpendicular to the shoreline, each species could be evaluated with 
regard to survival and reproduction at any point along this line. 
Based on the data available three species, gulf cordgrass, giant 
reed, and smooth cordgrass are adapted for use in the upper zone (Table 
20). Since gulf cordgrass occurs naturally, other species for use in
