The objective of this study was to test whether giant kelp forests in southern Baja California, Mexico could be restored using transplantation of juvenile plants or seeding with sporophylls. This could speed up the recovery of kelp forests, which supply food to important fishery species (e.g. abalone) and raw material for alginate production.
Site Selection Criteria:
The selected site was inhabited by Eisenia arborea, and had rocky substrata, moderate wave action, and was near to a sea lion colony, which may reduce ﬁsh grazing on transplanted giant kelp.
Cause Of Decline:
The giant kelp, Macrocystis pyrifera, forms extensive forests in the North Pacific. This kelp forms important marine forests as they provide habitat, have high productivity and support commercial industry. The size of giant kelp forests varies greatly due to environmental disturbances such as El Niño. Kelp forests were devastated in California in the 1982/1983 El Niño and subsequent storms.
