Threatened and Endangered Mammals

Species Accounts

The list below provides access to species accounts for 31 species and subspecies of mammals listed as either threatened or endangered by the State of California or the federal government. This list is in alphabetical order, by the general name of the animal (for example: fox, rat, whale, etc.).

Each species account contains the latest status report from the Department of Fish and Wildlife's periodic report on the status of these species. Each account also may contain links to additional, available status or life history information.

The list and the accompanying species accounts may not be complete or reflect the current legal status of these mammals because of listing activities more recent than the status accounts in the links below. The current legal status for each species is provided online (PDF) and is updated quarterly.

For more information on the species listed below, use the CDFW's Species Explorer. Please note, the Species Explorer is still being worked on. Not all species might appear in the database.
