|Scientific Name:||Andrias davidianus|
|Species Authority:||(Blanchard, 1871)|
Sieboldia davidiana Blanchard, 1871
|Taxonomic Notes:||This species is sometimes assigned to the genus Cryptobranchium.|
|Red List Category & Criteria:||Critically Endangered A2ad ver 3.1|
|Assessor(s):||Liang Gang, Geng Baorong, Zhao Ermi|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)|
Listed as Critically Endangered because of an observed drastic population decline, estimated to be more than 80% over the last three generations, due to over-exploitation. The generation length is estimated to be 15 years.
|Range Description:||The largest of all amphibian species (sometimes growing to more than one metre in length) this species is widespread in central, south-western and southern China, although its range is now very fragmented. It occurs from 100–1,500 m asl. Records of the species in Taiwan, Province of China, might be the result of introductions.|

|Population:||This species was once reasonably common but has declined catastrophically over the last 30 years, principally due to over-exploitation, and it is now very rare, with few surviving populations known.|
|Habitat and Ecology:||It lives and breeds in large hill streams, usually in forested areas. Females lay approximately 500 eggs in a string in an underwater burrow or cavity that is occupied by a male. Eggs are fertilized externally and are guarded by the male until they hatch after 50-60 days. Larvae then develop in the streams, taking food after about 30 days (Haker 1997).|
|Major Threat(s):||Commercial over-exploitation for human consumption is the main threat to this species. It has also suffered from habitat destruction (e.g., from the construction of dams) and habitat degradation (e.g., water pollution from mines). Although there is commercial farming of this species, the vast majority of Chinese Giant Salamanders being traded are believed to originate from the wild.|
|Conservation Actions:||In China, this species is listed as a Class II state major protected wildlife species. It occurs, or at least used to occur, in many nature reserves within its range, and some nature reserves even use the species as their main conservation target, such as Zhangjiajie Giant Salamander Nature Reserve. Captive rearing of animals has achieved some success, but these projects are mainly to meet the market demand. It is not clear whether or not animals are actually being bred in captivity. It is listed on CITES Appendix I.|
