California is renowned for its rich and unique biological diversity, geologic features, and natural communities. In fact, over 30% of all plant and vertebrate species in the United States occur in California. Many are endemic to the state, including 31% of plants and 65% of vertebrates. California also supports the highest human population in the United States. Human demand for California’s resources can impact the habitats that support this biodiversity, leading to risk of population decline. The California Department of Fish and Wildlife (CDFW) oversees the conservation and recovery of rare, threatened, and endangered species.

CDFW prepares periodic reports summarizing the status of all species listed as endangered, threatened, or candidate under the California Endangered Species Act (Fish and G. Code § 2079). These reports are submitted to the Commission, the Legislature, and the Governor, and are made available to the public via the links below.

These reports provide information on the range and distribution of each listed species and describe factors affecting their population levels. The reports also highlight conservation and recovery activities being implemented.
