The Disappearing Kelp Forest[6]
If you were to dive into the cool coastal waters of the Channel Islands, you might find yourself swimming through a magnificent underwater forest of enormousalga called kelp. Kelp is a type of seaweed that can grow almost two thirds of a meter per day. Kelp forests provide a home for hundreds of species, like sea urchins, brittle stars, and sea slugs.
Generally, an increase in sea urchin density at Johnson’s Lee South is associated with a decrease in kelp density. However, other factors in the ecosystem such as disease outbreaks, pollution, and other human activities may alter this relationship.. After severe El Niño events, large numbers of sea urchins appear in the kelp forest, which reduce kelp density.
