Artificial beaver dams California : In northern California, artificial beaver dams helped recreate lost wetland habitat, while juvenile coho salmon survival in restored habitat rose from 8% to 60%.
The Scott River valley was once home to so many beavers that it was known as Beaver Valley. Their dams created an enormous riverine wetland that provided habitat for juvenile coho salmon and other wildlife. They also created cold, slow-moving habitat favored by young coho.
