Distribution and endemic causes of existing endangered and critically endangered species of snakes in China

China has a vast territory, rich resources, diverse habitats, and many unique species. Paying attention to China’s endemic species can increase a deeper understanding of these endemic species and protect biodiversity at the same time. This study is mainly about the endemic species of snakes in China and is also a partial summary of the research on snakes in China. Use literature research methods to study the distribution, endemic causes, and population trends of endangered and critically endangered snake species in China. This helps us understand how to protect the populations of endangered and critically endangered species of snakes and better study them. The study found that most endangered and critically endangered Chinese endemic species are distributed in the Qinghai-Tibet Plateau, Sichuan, and other northwest areas, while a small number are distributed in Liaoning, Hong Kong, Taiwan, and other regions. Part of the reason for the uniqueness is that the unique geographical environment is suitable for the survival of snakes, and the other part is forced selection due to relatively isolated geographical location or crustal movement. This research aims to better understand and pay attention to China’s endemic snake species and protect endangered and critically endangered species.
