MENDOCINO CO., 1/24/26 — After decades of decline, endangered coho salmon have returned to the coast in numbers that more than double the targets set by habitat restoration projects. In 2008, just 5,000 coho were estimated across the entire state, one percent of their historic numbers; over the winter of 2024-25, more than 30,000 were counted in Mendocino County alone, showing that recovery is possible. Conservationists say that while it’s still too early to tell what this season’s numbers might be, it’s looking promising for another good year.
Over the past decade, the Nature Conservancy, Trout Unlimited, the Mendocino County Resource Conservation District, NOAA Fisheries, California Department of Fish and Wildlife, local landowners, tribes and other partners have restored habitat across the Ten Mile, Navarro, Big River, and Noyo River watersheds. Their work has included building side channels, off-channel ponds, large wood structures, and wetlands to support juvenile coho salmon. These structures give young coho salmon safe places to hide from predators, slow-moving water to rest in during storms and abundant food, creating the kind of habitat they need to survive winter storms and grow before heading to the ocean.
