Central California Coast CohoPopulation Decline
The impacts of clear freshwater and estuarine habitats reduced instream flow, and increases in stream temperatures are more or less visible - less noticeable change in species productivity and diversity. Habitat restoration is helping; however, it may not have the expected immediate effects on central coast coho populations, which may suffer from this lost genetic diversity and possible adaptations to degraded conditions.
Central California Coast coho were first listed as threatened under the Endangered Species Act in 1996, and then reclassified as endangered in 2005.
Data showed the species declining throughout its range, except in two places: the Russian River and Scott Creek.
