Kelp Forest grows on the Rocky Reef at San Clemente Island, Giant Kelp
The Kelp Forest and Rocky Reef of San Clemente Island. Giant kelp grows rapidly, up to 2' per day, from the rocky reef on the ocean bottom to which it is anchored, toward the ocean surface where it spreads to form a thick canopy. Myriad species of fishes, mammals and invertebrates form a rich community in the kelp forest. Lush forests of kelp are found throughout California's Southern Channel Islands. USA
