CA Grizzly Research Network
In May 2016, a multidisciplinary group of scientists and other scholars based at UC Santa Barbara launched the California Grizzly Research Network, which is now a partner project of the Alliance. The CA Grizzly Research Network has developed a series of projects designed to answer key questions about the past and potential future of grizzlies in California.
