This study reports on the restoration of seaweed beds using management-free methods, to help conserve the natural ecosystem.
Site Selection Criteria:
Sites for the foundation construction for the Eisenia and Ecklonia bed restoration were selected within 100 m of a natural kelp bed and with a depth at 5 m for Eisenia bicyclis and about 11 m for Ecklonia cava, values based on their natural vertical distribution.
Cause Of Decline:
At high densities, sea urchins can create and maintain areas dominated by crustose coralline algae and devoid of macroalgae, commonly called barrens. When sea urchins are removed from these areas, kelps are frequently able to recolonise the area.
