Sea star wasting disease was first spotted in spring 2013 near Vancouver and along southern and central California, but the Oregon coast was initially spared. Once abundant throughout their range in marine waters from Alaska, USA to Baja California, Mexico, sunflower sea stars experienced a severe population crash after the 2013 outbreak of the marine wildlife epidemic known as sea star wasting disease. New research documenting the population crash of the iconic sunflower sea star (Pycnopodia helianthoides), and complete absence of population recovery since the 2013 outbreak of the marine wildlife epidemic sea star wasting disease, was published today in the prestigious journal Proceedings of the Royal Society B.

Recruitment, an indicator of population recovery, has been spatially patchy and varied within and among regions of the coast. The fact that this has occurred along the whole west coast, from Alaska down into Baja California, suggests that its linked to a large-scale oceanographic change, Menge said. This remarkable partnership, which spans a broad geographic range, has come together to document the climate driven mass mortality of sunflower stars with local extinction in the south in California and Mexico and dramatic declines in the north across Washington, Canada and Alaska. The study calls for active management and a coordinated sunflower sea star recovery effort as key tools in kelp forest restoration. said Alyssa Gehman, a marine disease ecologist at the Hakai Institute, and an adjunct professor atthe UBC Institute of Oceans and Fisheries. Disease outbreaks can have substantial impacts on wild populations, but the often patchy or anecdotal evidence of these impacts impedes our ability to understand outbreak dynamics. Sunflower sea stars, listed as Critically Endangered by the International Union for the Conservation of Nature (IUCN), are generally thought to play a role in supporting healthy kelp forests via predation of kelp-eating purple urchins, but this important relationship has never before been quantified. A new study published by the Royal Society said sea stars are getting close to extinction as waters along the west coast, including in California and Mexico, warm faster because of climate change. The following picture was taken a day later, and the last picture, the day after that.
