Qualitative Collections 



Qualitative algal collections have been made monthly at each of 

 seven rocky shore sampling sites since March 1979. Two additional 

 stations (TT and MP) were added in October 1981. In the 1983 reporting 

 year, the collected flora was comprised of 126 species of algae, 

 exclusive of diatoms and cyanophytes. On a yearly basis, this flora has 

 remained generally constant over the past five years; changes are 

 summarized in Table 1. Since the qualitative collection program was 

 begun in 1979, a total of 146 species have been identified', this years 

 collection included over 88% of that total. Most of the remainder 

 represents small, rarely found plants.

Changes in the overall flora from year to year have been minor, but 

 floristic differences exist between stations and between months. Table
