As part of the CESA listing process, CDFW must prepare one-year status reviews for plants and animals designated as candidate by the California Fish and Game Commission (Commission). These one-year status reviews must be based on the best scientific information available to CDFW, must be scientifically peer-reviewed, and must include a recommendation to the Commission on whether listing is warranted. The table below includes links to one-year status reviews that have recently been completed by CDFW, and the Commission’s final determinations related to those species (if applicable). For more information on the CESA listing process and the Commission’s related proceedings, see the Commission’s page on Petitions to List Species Under the California Endangered Species Act. For a current list of species that are listed under CESA, please see the Threatened or Endangered Plant Species List and the Threatened or Endangered Animal Species List.
