Salmon Lose Diversity in Managed Rivers, Reducing Resilience to Environmental Change

Natural resilience is more important than ever in the face of unprecedented climate change.

The manipulation of rivers in California is jeopardizing the resilience of native Chinook salmon. It compresses their migration timing to the point that they crowd their habitats. They may miss the best window for entering the ocean and growing into adults, new research shows.

The good news is that even small steps to improve their access to habitat and restore natural flows could boost their survival.
