Kelp Forest Along North Coast Disappearing

Deforestation isn’t just happening on land. A new study from UC Santa Cruz suggests that the kelp forest along the Sonoma and Mendocino Coasts has declined by 95 percent since 2013. The study points two main causes: the explosion in the population of purple Sea Urchin, which eats the kelp, and two warm water events from 2014 to 2016. Researchers say that the kelp forest will not likely recover soon, partly because of the purple sea urchin and the difficulty in removing them. It also doesn’t help that the purple sea urchin’s primary predator, the sunflower sea star, has been hit hard by a wasting disease.

Saving Oregon s Rocky Coast: Checking In On The Sea Stars

A crew of researchers clad in orange fishing bibs trudges out to the rocky shore. It’s early in the AM – their visit timed to capture the brief window when the tides are so low, they reveal a usually-hidden intertidal spectacle. Clinging to the exposed rocks, among the mussels and wobbly sea anemones, are sea stars, colored in hues of tangerine and violet. The researchers’ mission? To pry the Ochre Sea Stars off the rocks, then measure and weigh them. Laurel Field is a faculty research assistant in the Menge Lubchenco Lab at Oregon State University. She led the team to this spot on Oregon’s south coast.
