Our friends at the Mountain Lion Foundation have partnered with Center for Biological Diversity with the aim to list the cougars in the Santa Ana Mountains as threatened under the California Endangered Species Act. This population is genetically different than other cougars in California and their very existence is threatened by habitat loss and limited wildlife corridors.

Thanks to our partnership with Chino Hills State Park and Caltrans 12, we secured the connection under the 91 freeway at Coal Canyon to connect the Santa Ana Mountains to the Puente-Chino Hills Wildlife Corridor, but other important connections still need to occur in neighboring counties to ensure their survival. Fingers crossed for a successful effort!
