SCIENTISTS WORK TO SAVE DISAPPEARING KELP FORESTS
Underwater kelp forests are sometimes called the rainforests of the sea, but - like the verdant jungles on land - the vast beds of seaweed are disappearing, hurting fisheries and coastal communities worldwide. A project off the coast of California is helping to restore them.
Divers are working in the waters off the Palos Verdes Peninsula in places known as barrens, which once were home to thriving kelp forests. Today, these parts of the seabed are thick with sea urchins, creatures that have proliferated because of pollution and other human activities. The divers are killing some of urchins to thin the population, which is sickly and malnourished. This restores the natural balance, says David Witting of the National Oceanographic and Atmospheric Administration.
The restoration work is helping young kelp plants take root and flourish. And the return of healthy kelp forests to this offshore area provides a habitat for sea life and again creates a place of natural beauty.
