The giant kelp Macrocystis pyrifera has considerable ecological and economic value, as it provides habitat and food for valuable marine life and is associated with increased biological productivity and fishing success. This value, and the decline of this species in recent years, has prompted development of restoration techniques.
Cause Of Decline:
Presumably, the present lack of naturally occurring Macrocystis pyrifera beds in the harbour is the result of poor water quality in the past and the relatively poor reproductive dispersal ability of Macrocystis.
