In 2013, a mysterious wasting disease wiped out a large portion of the local sea stars in northern and central California. For thousands of years, thick canopies of bull kelp formed an underwater forest spanning the foggy coast of Northern California. Their sunlit canopies can soar 150 feet from the ocean’s floor. Central California bull kelp forests remained in cooler waters and thus in better condition when the winter swells hit, and a much greater percent survived. It’s a cold clear morning, a good day to be out experiencing a still very much wild area of California. Studies on microscopic stages of kelp suggest that kelp is sensitive to sewage, industrial waste discharges, and other causes of poor water and sediment quality. In other words, they can disappear and reappear based on the oceanographic conditions and the population sizes of their primary herbivores. Kelp are not plants, but rather extremely large brown algae, and many different species of kelp make up kelp forests. Shrunken abalone due to lack of food, October 2015. A 2016 study noted a global average decrease in kelp abundance, with warming waters directly driving some losses. CDFW is temporarily closing its high public use areas, including visitor centers and license counters, to help slow the spread of COVID-19 (coronavirus). Red abalone have been severely impacted by the loss of kelp and thus lack of food, causing the abalone fishery to close until at least 2021. “But the system just can’t recover, even with a shift back in water temperature,” says Kyle Cavanaugh, an assistant professor of geography at the University of California, Los Angeles who has studied global kelp ecosystems. Finally, people started realizing that the kelp was being eaten by seaweed eating fish. Our resources pay attention to sustainability and keeping kelp alive. There are many opportunities for involvement, whether you are a scuba diver, freediver or just a concerned community member!

Kelp Forests Off California Coast Disappearing At ‘Unprecedented’ Rate April 18, 2016 at 10:39 am Filed Under: California , Disappear , Kelp Forest , Pacific Ocean Natural Coastal Kelp Forests are Disappearing around the Globe In northern California, a series of events that began several years ago has destroyed the once-magnificent bull kelp forests along hundreds of miles of coastline. Non-point and point source pollution including sewage, industrial disposal, and coastal runoff might contribute to kelp forest degradation. This lecture will be held by webcast only. In 2007, kelp forests were also discovered in tropical waters near Ecuador.. Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms and are a source for understanding many ecological processes. Canopies that once covered much of the ocean’s surface have disappeared and the little kelp that remains is actively mowed down by a voracious grazer—the purple sea urchin. The view of northern California’s beautiful coastline has historically been pristine and breathtaking. Scientists hope also to try to develop commercial uses of the purple urchins, thus ensuring long-term sustainable harvesting. Her dive computer told her it was time to ascend, which meant that she would have to stop searching for the endangered white abalone hiding in the waving fields of red and gold gorgonians. By 2014, a large patch of warm water developed off the coast, creating a catalyst that has further changed this underwater environment. bad for kelp: it causes reduced photosynthesis and loss of canopy blades. (Photo credit: A. Maguire) Warmer than normal summers and seasonal changes to currents that bring fewer nutrients to kelp forests (both sometimes occurring naturally) combine to weaken kelps and threaten their survival in some years.

Today, bull kelp forests should be the foundation of our nearshore coastal ecosystem. As Oceans Warm, the World’s Kelp Forests Begin to Disappear. Large aggregations of purple urchins are wiping out kelp forests, creating pink barrens and out-competing other species, such as abalone, for food. These negative effects reach from the ocean to the shore. The kelp cannot last long under such conditions, and much of it is lost. Which is why an unprecedented alliance of scientists, fishers, surfers, entrepreneurs, and experts is coming together to revive California’s vital kelp ecosystem, decimated by a warming ocean. The persistent warmer sea temperatures stress the kelp forests to the point that growth and reproduction have slowed dramatically and caused damage to remaining fronds and tissue. Before heading to a CDFW facility, contact the regional headquarters office to determine if that facility is open. California Department of Fish and Wildlife (CDFW) biologist Justin Dellinger and a Wildlife Services houndsman are preparing gear to go out looking for fresh mountain lion tracks in this vast landscape. “To address the impacts of the massive marine heat wave and kelp deforestation on the north coast we are going to need to shift our priorities and resources and come up with creative solutions,” says Dr. Laura Rogers-Bennett, a CDFW senior environmental scientist specialist based out of the Bodega Bay field office in Sonoma County. But perhaps the most critical effect is that the purple urchin populations now thrive without their primary predators, and are left to graze the kelp unchecked. Sea otters and sea urchins are particularly important to the health and stability of kelp forests. But instead of trees, these forests are made of kelp. At nearly 130 feet underwater, CDFW abalone researcher Dr. Laura Rogers-Bennett didn’t have much time. © Sunflower stars in particular prey voraciously on sea urchins—which keeps urchin grazing on kelp forests in check.

The destruction of the kelp forests is a major disruption of marine ecosystems that will have far-ranging impacts. Harvesting abalone for dinner used to be as fundamental to a Southern California lifestyle as fish tacos and flip-flops. Protection and food all in one. But perhaps the most critical effect is that the purple urchin populations now thrive without their primary predators, and are left to graze the kelp unchecked. Adding Biochar and Mycorrhizae to soil augments its sustainability and long term Carbon sequestration. This urchin removal project is a massive undertaking. For thousands of years, canopies of thick bull kelp (Nereocytis luetkeana) could be found along the coast of northern California, creating a rich subtidal home for the many fishes and invertebrates that lived and thrived in this region of the state. Kelp forests are key assets in the effort to control the effects of climate change and are likewise quite susceptible to these effects if not given a helping hand. (K. Joe), Media Contact: Along the north coast, purple urchins are now successfully outcompeting red urchins and abalone. Harbor seals and sea lions are also hungry and feeling the effects.
