Beaver-like dams in California raise young salmon survival rate to 60%
Restoration projects in California's Scott River watershed are using beaver dam imitations to dramatically improve coho salmon survival. These human-built structures slow water flow and lower temperatures, creating conditions favorable for juvenile salmon to thrive. In one monitored creek, survival rates for young salmon jumped from just 8% to 60% following the intervention. The restored habitats also strengthen the watershed's resilience against drought. Conservationists say the results highlight the urgent need to rehabilitate wetland ecosystems for endangered salmon populations.
