A salmon success story during the drought

Average returns of fall-run Chinook salmon on the Shasta River in the past four years have quadrupled, even during the drought. No one knows for sure why. However, the condition of the habitat dramatically improved soon after cattle were fenced out of an ecologically important spring-fed tributary, Big Springs Creek. Ann Willis, a Center researcher who has monitored the changes for several years, tells the story to Capital Public Radio's environment reporter Amy Quinton.
