Collected Data of Local Ecological Knowledge to Predict Current Status and Potential Threats of salamander (Andrias davidianusin) in Zhengan County of Guizhou Province, China

Through statistical analysis of the comparison data, the number of wild CGS decreased actually followed the increase of artificial framing. Because of the source of breeding to catch wild CGS, overharvesting was likely the most reason to make wild CGS decline. The collected data could be analyzed completely and provide a perfect evidence for local ecological knowledge of rapidly shifting baselines. it is suggested that conservation research is based on ecological data collected by researchers or scientists who conducted a series of fieldworks, but local ecological knowledge about the status of the protected species is usually held in local people who live in protected area or around of this region[2'10_12], and local ecological knowledge could provide a unique source of data for conservation, especially in efforts to investigate the status of rare of possibly extinct species[7_8]. First we employed Pan's data121 of the temporal distribution of respondents saw salamanders last time, his original data was from 1950 to 2015 years, and our data was from 1970 to 2015 years. First human-caused extinction of a cetacean species [J].
