Record Return of Endangered Central California Coast Coho Salmon

Significant Surge in Salmon Numbers
During the 2024–2025 spawning season, monitoring teams estimated that over 30,000 endangered Central California Coast coho salmon (CCC coho) returned to the rivers of the Mendocino Coast. This figure marks a dramatic increase from the previous record of 15,000 fish and a substantial rise from the mere 3,000 fish that returned annually over the past decade. The surge is attributed to several factors, including the reconnection of spawning streams to mainstem rivers and extensive habitat restoration projects supported by NOAA.
Restoration Efforts and Their Impact
NOAA has funded more than 100 restoration projects since 2000, significantly enhancing the habitat available for salmon to spawn and grow. Key organizations involved in these efforts include Trout Unlimited, the California Department of Fish and Wildlife, and the Pacific States Marine Fisheries Commission. Monitoring teams conduct bi-weekly surveys across approximately 500 miles of habitat, counting adult fish and their nests, known as redds. The results from these surveys have been overwhelmingly positive, with reports of salmon in areas where they had not been seen for years, such as Usal Creek and the Gualala River watershed.
Monitoring and Observations
The monitoring process involves teams visiting selected stream sections to assess fish populations. David Ulrich, a senior scientist at Mendocino Redwood Company, noted the excitement of observing 50 to 100 fish daily during peak spawning, a stark contrast to previous years when no fish were seen. Observations also highlighted coho salmon occupying narrow tributaries, demonstrating their adaptability and the success of restoration efforts.
Factors Contributing to Recovery
Several conditions have aligned to support this resurgence. Favorable ocean conditions, improved fisheries management, and changes to California's forest practice rules have contributed to better survival rates. Marine survival rates for coho salmon have reportedly improved from around 2% to approximately 8%, indicating a healthier marine environment. NOAA Fisheries scientist Nate Mantua emphasized that the combination of good hydrology and ocean conditions has allowed salmon to thrive.
Challenges Ahead
Despite the encouraging numbers, the CCC coho salmon remains an endangered species, and their recovery will require ongoing efforts in both freshwater and marine ecosystems. The species faces threats from erratic weather patterns, including droughts and intense winter storms. Monitoring for the upcoming 2025–2026 season is already showing promising early results, with reports of around 400 coho on the North Fork Navarro River.
Official Statements & Responses
Joshua Fuller, NOAA’s Coastal California Branch Supervisor, expressed optimism about the recovery efforts, stating, “Recovering salmon is undeniably challenging... These numbers are very encouraging and demonstrate that recovery is possible.” Meanwhile, Anna Halligan, director of the North Coast Coho Project for Trout Unlimited, highlighted the significance of recent restoration projects, noting, “Salmon have not had the ability to spawn in this area for more than 70 years.”
