Petitions to List Species Under the California Endangered Species Act

The California Endangered Species Act (CESA) was originally enacted in 1970 to conserve and protect animal species at risk of extinction. In 1984 CESA was amended to include plants and invertebrates at risk. Organizations and members of the public can petition to have plants and animal species designated threatened or endangered under CESA.

More information about California's threatened and endangered species can be found on the California Department of Fish and Wildlife's CESA page.

The current list of plants of California declared to be endangered, threatened or rare can be found in Section 670.2, Title 14, California Code of Regulations.

The current list of animals of California to declared to be endangered or threatened can be found in Section 670.5, Title 14, California Code of Regulations.
