Tribe Brings Back 20-Legged Sea Star After Pandemic

After an underwater pandemic nearly destroyed them, sunflower sea stars are getting a second chance thanks to an unlikely partnership between scientists and a Pacific Northwest tribe.

The sunflower sea star, a 20-legged predator once common in kelp forests off Washington state, nearly vanished a decade ago. An underwater disease outbreak starting in 2013 killed billions of these creatures along the Pacific coast, leaving kelp forests vulnerable and out of balance.

Now, researchers are working with Indigenous communities to bring them back. The tribe's traditional knowledge of marine ecosystems and their commitment to ocean stewardship has proven essential to the recovery effort.

Sunflower sea stars play a crucial role underwater. These massive predators keep sea urchin populations in check, preventing the urchins from destroying kelp forests. Without the sea stars, urchin populations exploded in many areas, creating underwater "barrens" where thriving kelp forests once stood.

The reintroduction program carefully raises young sea stars in protected environments before releasing them back into the wild. Scientists monitor their survival rates and track how they adapt to their original habitats.

The collaboration between Western science and Indigenous ecological knowledge has made the project stronger. Tribal members have observed these waters for generations and understand the subtle changes in marine ecosystems that data alone might miss.

Early results show promise. The young sea stars are surviving in their new homes, and researchers are hopeful they'll begin reproducing naturally. Each successful reintroduction brings kelp forests one step closer to their former health.

The Ripple Effect

Restoring sunflower sea stars means more than saving one species. Healthy kelp forests support hundreds of other marine creatures, from fish to seals to whales. They also absorb massive amounts of carbon dioxide, helping fight climate change.

The partnership demonstrates how combining traditional ecological knowledge with modern science creates better conservation outcomes. Other coastal communities are watching closely, hoping to replicate this model for their own endangered species.

Fishing communities stand to benefit too, as healthier kelp forests support the fish populations they depend on for their livelihoods.

The project shows that even after devastating losses, ecosystems can bounce back with the right help and patience.
