Environmental disaster continues to decimate bull kelp forests, red abalone in Northern California

摘要

The California Department of Fish and Wildlife has monitored Northern California kelp forest ecosystems and red abalone populations for the past 20 years.Surveys completed in the summer of 2018 continued to document mass abalone starvation and population collapse. A limited survey effort in 2019 saw no improvement in environmental conditions for red abalone populations. On average, for Sonoma and Mendocino counties combined, red abalone densities have been reduced by 75 percent since 2014.
