Fig. 11 Transect 6 showing the intertidal zonation of the dominant plants and animals on the steep rocky shore on the exposed western end of Lion Rock, Piha. Illustrations by Margaret Morley, Morton & Miller (1968), Powell (1979, 1987), and Adams (1994). Thick line = interval as dominant or co-dominant zoning organism, solid line = interval as subdominant zoning organism, dashed lines = interval of sporadic occurrence.
