Kelp forests are some of the most productive and diverse of the planet’s ecosystems and have a key role in the marine environment. Urchins move in "herds," and enough urchins may remain in the "barrens" of a former kelp forest to negate any attempt at regrowth. Some of these kelp forests were so dense that light hardly penetrated to the seafloor. NOAA's national marine sanctuary offices and visitor centers are closed to the public while the waters remain open for responsible use in accordance with CDC guidance and local regulations. Many fish species use kelp forests as nurseries for their young, while seabirds and marine mammals like sea lions and sea otters use them as shelter from predators and storms. Sea otters, playing a critical role in containing the urchin populations, prey on urchins and thus control the numbers of kelp grazers.
