The kelp forest eight years ago that formed a leafy ocean canopy along the Northern California coast has almost completely disappeared, and scientists studying kelp and species dependent on it worry it won’t. Can be reversed
A new study from UC Santa Cruz has found that kelp forests on the Sonoma and Mendocino coasts have decreased by an average of 95% since 2013, analyzing satellite imagery back in 1985 to determine how many factors led to their destruction. Seaweed forest The decline included an explosion of the purple urchin population, which ate it, and two ocean heat waves. Research has shown that unprecedented destruction is associated with abnormal ocean heating, and that kelp forests tend not to recover anytime soon, in part because urchins are extremely difficult to get rid of.
