EQUITABILITY 
Figure 29. Seasonal variation in the Pielou's Equitability Index for the 
intertidal zone at the nourishment beach at Fort Macon, June 1977 
to August 1978, and the comparison beach at Emerald Isle, December 
1977 to August 1978. The actual period of nourishment is repre- 
sented by a slashed line below the X-axis. The bull's eye symbol 
represents an equitability index that is undefined because no 
organisms were found.
