Science Sunday—Kelp Forest Resiliency: Life after Sea Urchin Grazing

Along California’s Central Coast, sea urchins have recently transformed a long-established kelp forest into an underwater mosaic—patchy forests interspersed with barrens void of kelp. What causes sea urchin outbreaks that result in widespread kelp deforestation? How will they end and when will kelp forests recover?

Join Joshua Smith as he disentangles the mechanisms that underpin kelp forest resiliency. Come learn what drives this changing ecosystem.
