![]() Added more than 6,000 pieces of large woody debris to improve instream habitat complexity.Enhanced more than 200 miles of streams.In our first five years of the Species in the Spotlight initiative, we made the following progress toward stabilizing the species and halting their decline: These actions are working to save Central California Coast coho salmon from extinction and are paving a path forward to recovery. Monitoring and Research of a dynamic and changing landscape.Partnering and outreach to advance recovery.Continuing and expanding conservation captive broodstock programs to increase species and spatial diversity and support population recovery.Improving instream flow to support freshwater rearing.In our 2021–2025 action plan, we prioritized the following activities: It details the focused efforts that are needed over the next 5 years. The Species in the Spotlight 2021–2025 Priority Action Plan builds on the 2016–2020 Priority Action Plan and the Recovery Plan for the Evolutionarily Significant Unit of Central California Coast Coho Salmon. This remote side incubator is filled with salmon eggs that are bathed in cool, well-oxygenated water from the stream. Recovery: Species in the Spotlight Priority Actions Restoration and additional monitoring of habitat and species response to these events is necessary to repair and re-evaluate how climate-driven processes influence Central California Coast coho salmon’s survival and recovery. The impact of droughts, fires, and flooding on Central California Coast coho salmon habitat will remain for many generations to come. Fires of this magnitude cause substantial damage to riparian habitat and instream wood shelter, as well as increased landslides and sediment input to streams. Unprecedented wildfires throughout the species’ range have become a significant habitat concern. ![]() California now routinely experiences above-average temperatures and well below average temperatures. Agriculture and legacy logging practices have straightened rivers and streams, deforested the river banks, and extracted water for farming, watering lawns, and other uses.Ī critical emerging challenge to Central California Coast coho salmon survival and recovery is the increased frequency of severe weather patterns resulting from climate change. While there is no single factor responsible for Central California Coast coho salmon decline, both human activities and natural events have degraded their habitats. View the critical habitat maps or GIS data for these coho. The remainder of their life cycle is spent foraging in estuarine and marine waters of the Pacific Ocean.Ĭritical habitat was designated for the Central California Coast coho salmon in 1999. These fish need cold, clean freshwater streams to lay their eggs, along with side channels and floodplains where young fish can find food and hide from predators. Spawning habitat is comprised of small streams with stable gravel substrates. HabitatĬoho salmon spend approximately the first half of their life cycle rearing and feeding in streams and small freshwater tributaries. Conservation hatchery programs have supported the species in these two areas, and we have recently observed some increases in abundance. Data demonstrated that the species was declining throughout its range, except in two places: the Russian River in Sonoma County, and Scott Creek, in Santa Cruz County. ![]() Population Statusīy the late 1990s, Central California Coast coho salmon were on the verge of extinction. The Central California Coast coho salmon ESU represents the southern extent of the species' larger range. This ESU of coho salmon originates from rivers south of Punta Gorda, California to and including Aptos Creek, as well as such coho salmon originating from tributaries to San Francisco Bay.
