The frequency of the symbols 
Suggests the relative frequency of 
the species in each area, except for. 
the very common Ascophyllum, 
Fucus and Bostrychia, whose abun- 
dance on the wharves is such that 
it can not be so indicated in the 
space available for symbols. The 
placing of these symbols on the 
landward side of the wharf line, in 
some cases is to avoid crowding, 
and still indicates that these species 
are present on the vertical wall of 
the wharf.
