Buoyed artificial reefs allowed the recovery of U. pinnatifida and other macroalgae. There were some losses of transplanted U. pinnatifida partly caused by withering after the reproductive maturation period, but S. japonica and other macroalgae species were naturally recruited and increased on the buoyed beds. In contrast, the barren habitat remained at the area grounded to the bottom in the inner bay. Overall, restoration efforts using the artificial buoyed reef resulted in the success of the recovery of macroalgal habitats in the sea urchin dominated barren grounds by the reduction of grazing pressure of sea urchins.
