Northwest Tribe Joins Effort to Rescue Sunflower Sea Stars from Extinction

The sunflower sea star, a once-common predator with up to 24 arms, has vanished from vast stretches of the Pacific coastline. In a collaborative push to reverse this decline, the Samish Indian Nation has partnered with scientists at the University of Washington to rear and reintroduce the species in its native waters.

The crisis began in 2013, when a mysterious wasting disease swept through sea star populations along North America's west coast. Sunflower sea stars were hit especially hard, with some estimates suggesting a loss of over 90% of their numbers. Today, they are listed as critically endangered by the International Union for Conservation of Nature (IUCN), making them one of the most imperiled marine invertebrates in the region.

This collapse has ripple effects across the underwater ecosystem. Sunflower sea stars are top predators that help control populations of sea urchins, which graze on kelp forests. With fewer sea stars, urchin numbers have exploded in some areas, leading to the destruction of vital kelp habitats that support countless fish and other marine life.

The recovery project, led by the Samish tribe

The recovery project, led by the Samish tribe and UW researchers, focuses on breeding the animals in captivity. The team has successfully raised juvenile sea stars in lab conditions, carefully monitoring their health and behavior before any potential release. This painstaking approach aims to ensure the young stars are strong enough to survive in the wild and resume their ecological role.

For the Samish people, the effort carries deep cultural significance. The sunflower sea star holds a place in traditional stories and practices, and the tribe's stewardship of these waters extends back generations. By joining forces with university scientists, they are blending ancestral knowledge with modern conservation techniques to give the species a fighting chance.

While the road to recovery is long, early results offer a glimmer of hope. The team has already documented survival of released juveniles in controlled test sites, and they are now expanding efforts to more locations. The ultimate goal is not just to bring back a single species, but to restore the balance of the entire nearshore marine environment.
