The objective of these restoration efforts was to remove urchins in order to restore giant kelp habitat for environmental purposes, and to enhance local recreational diving.
Site Selection Criteria:
The restoration site is a large reef that is popular among recreational divers. The reef is composed of exposed rocky reef with canyons and crevices. The toe of the reef extends south from shore to a depth of about 15m and many areas of the reef reach up to the surface and are exposed during big swells or low tides. Despite the fact that adjacent kelp forests have been restored, this reef was barren as of the summer 2010.
Cause Of Decline:
Seaweed beds play an important role in biological production, water quality purification and sediment stabilisation. Furthermore, seaweed beds contribute to the increase in catches of useful seafoods. Due to coastal development or coastal environment degradation, marine vegetation is decreasing.
