Biological Environment

Three basic intertidal systems: a sheltered northern platform; an exposed southern platform; and a narrow exposed eastern platform (Laxton & Laxton 1988c)

Immediate vicinity of the outfall: barnacles, Ulva and encrusting Corallinaceae algae; further to the north: Corallinaceae algae, Corallina, Ulva and chitons.

Rock pools: Corallina, Ulva, Sargassum and Cystophora. Hormosira, Enderachne and Enteromorpha but less common. Kelp occurs in the lower intertidal areas.

Subtidal habitats: kelp (Ecklonia radiata) forest, turfing algae assemblages and Lithothamnion (encrusting Corallinaceae algae) pavement (Laxton & Laxton 1983, 1988c). In deeper water the algal assemblages existed in competition with sponges, ascidians and other sedentary animals.
