Hugging the coastline, they extend from just beyond the breaking waves to depths of <30 meters. And so Burdick and her colleagues have been seeding the abalone in restored kelp forests like this one.

Re-surveys of 11 locations at the easternmost extent of Tierra del Fuego originally conducted in 1973 showed no significant differences … What is a kelp forest? Sea otters and some 800 other marine species depend on them, as do fishers in the state’s abalone and red urchin industries, now devastated by a purple urchin population explosion. Back at Honeymoon Cove, Heather Burdick, director of marine operations for the Bay Foundation, uses a long pole to scoop up kelp, which she stores in a cooler, to be used as food for abalone being raised in the organization’s portside lab.

The kelp forests of southern South America are some of the least disturbed on the planet. Marine life in a kelp forest on Cortes Bank, California. Rather than using roots — as seagrasses do, which unlike algae are true plants — they cling to the rocky seafloor using growths called holdfasts. But it’s a huge increase since the late 1960s, when kelp had become all but extinct in that area. Map by National Geographic Archaeological finds indicate that pre-Clovis people arrived in the Americas before 13,500 years ago, likely via the “kelp highway.” The red markers indicate the shape of projectile points found at the associated sites. Gray whales shelter their young in kelp forests. National Geographic Society is a 501 (c)(3) organization. The algae can also be used as biofuel, and when fed to cows dramatically cuts planet-warming methane emissions from their burps. “Preventing local extinction is key to future success,” says Rogers-Bennett.

Through photosynthesis, kelp forests boost oxygen levels in the ocean while helping protect the coast from erosion by reducing the speed and size of waves. Jump to. But when the predators that keep their numbers in check disappear, the population booms and can quickly consume a kelp forest, creating what is called an urchin barren. Sections of this page.

The Bay Foundation now hires out-of-work red urchin divers to methodically cull the purples by smashing them with hammers. The Bay Foundation’s Ford pilots to a spot called White Point, where SeaTrees will fund removal of a 3,200-square-foot patch of urchin-infested reef as part of a reforestation project set to begin in the fall. One third of southern California’s kelp forests are found within Channel Islands National Park and Channel Islands National Marine Sanctuary. “Abalone play a critical role in the kelp forest,” says Rogers-Bennett, noting that the grazers clean reefs, which attracts other marine life—including predators of purple urchins—to the seaweed ecosystem. National Geographic Headquarters For decades, this cove was largely devoid of life, devastated by seaweed-eating purple urchins. Water at those depths is richer in nutrients; seaweed riding the kelp elevator grew three times faster and weighed four times more on average than kelp at a control site, according to Diane Kim, associate director of special projects at USC’s Wrigley Institute for Environmental Studies.

Kelp in some areas of Southern California already had been reduced by 75 percent over the past century due to pollution and overfishing of species that protect kelp ecosystems. Each year the program collects size and abundance data for 72 categories (taxa) of algae, invertebrates, and fish that are indicators of ecosystem health.
