A collaborative effort between the Samish Indian Nation and University of Washington researchers marked a significant milestone in efforts to restore sunflower star populations in the Pacific Northwest. The team transported 20 three-year-old sunflower stars, bred in captivity at Friday Harbor Laboratories, to be released into traditional Samish territory in the San Juan Islands. The initiative represents an attempt to recover a species that has experienced catastrophic population decline.
Sunflower stars, which can grow to over three feet in diameter and move at speeds up to five feet per minute across the ocean floor, have been decimated by sea star wasting disease caused by Vibrio bacteria. Scientists estimate that approximately 90 percent of sunflower stars have been lost, with the disease spreading from northern Mexico to Alaska and affecting numerous sea star species. The wasting disease outbreak, which researchers attribute partly to ocean heat waves amplified by climate change, has led international scientists to declare the sunflower star critically endangered. Canada has classified it as endangered, and the Biden administration proposed protection under the Endangered Species Act, though the current administration has not acted on that proposal.
The laboratory breeding program required researchers to develop husbandry techniques for the little-studied species through trial and error. Researchers even successfully treated some animals when wasting disease infiltrated the lab environment. The initial release scheduled for last October was postponed after divers detected the disease resurgence in the San Juans. The subsequent release proceeded despite ongoing concerns from the research team about unforeseen complications.
Sunflower stars function as a keystone species with significant ecological importance. By preying on sea urchins, they protect kelp forests from overgrazing, maintaining critical marine ecosystems along the West Coast. The Samish Nation has prioritized this restoration effort as part of broader environmental stewardship, though sunflower stars historically played a less prominent cultural role compared to salmon. Researchers expressed emotional connections to the animals, naming individuals after snack foods and noting distinct behavioral personalities among the stars.
