In order to better illustrate the conservation status of California's reptiles and amphibians, the special status listings used by several organizations are listed on this web site. These organizations track the condition of plants and animals to determine which ones are thriving and which are declining in order to target conservation efforts towards those plants and animals that need it most. The status under the U. S. Endangered Species Act and the California Endangered Species Act are also listed.
It would not be possible for me to track every individual organization to keep up with their listings, so the listings used here are taken from a collection of listings produced by the California Department of Fish and Game, named the Special Animals List. This list is used to monitor the status of certain potentially vulnerable California animals. (If an animal is not on this list, there will be no status listed on this site, even though one may exist.)
Animals are placed on the list for a number of reasons:
- they are listed or proposed for lising under the State or Federal Endangered Species Acts;
- they are not listed but meet the criteria for listing;
- they warrant monitoring because they are rare, declining, or otherwise vulnerable;
- their population in California is at the edge of their range and is threatened with extirpation in California;
- they are closely associated with a natural habitat that is rapidly declining in California;
- they are listed as vulnerable by other state, federal, or non-governmental organizations.
Status information on this web site is taken from the January 2011 Special Animals List and the January 2013 State and Federally Listed Endangered and Threatened Animals of California List. The Special Animals list is updated irregularly, although major changes do not happen often. I will try to make updates from the new list when it is released, however I might not do so for some time after the list is released. You can check for yourself to find out if any changes have been made since this site was last updated by looking at the most current Special Animals List which can be downloaded from this page: http://www.dfg.ca.gov/biogeodata/cnddb/plants_and_animals.asp.
The current State and Federally Listed Endangered and Threatened Animals of California List can be downloaded from the same page.
In some cases the scientific or common name used on this web site is not the exact name used on the Special Animals List. If the names differ, we will note the name used on the Special Animals List.
Below is a list of some of the status listings and codes used on the Special Animals List that are also used on this web site. There may be other status designations on the list which are not listed on this web site. For a full list of all status codes, a complete explanation of their meaning, and links to the organizations with their own explanations, see the Special Animals List, or go to the organization's web site.

GX - Presumed Extinct (species - Not located despite intensive searches and virtually no likelihood of rediscovery.
GH - Possibly Extinct (species - Missing; known from only historical occurrences but still some hope of rediscovery.
G1 - Critically Imperiled - At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors.
G2 - Imperiled - At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors.
G3 - Vulnerable - At moderate risk of extinction due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors.
G4 - Apparently Secure - Uncommon but not rare; some cause for long-term concern due to declines or other factors.
G5 - Secure - Common; widespread and abundant.
