Amphibians are organisms that are very sensitive to changes in their environment, which has an impact on their survival, such is the case of emblematic animals such as ambistomatids, a family of amphibians whose larval forms are commonly known as axolotls, of which 18 species are known in Mexico and where one of them is the Bajío axolotl Ambystoma velasci. In this paper I make a chronicle and a reflection on the natural history of a population immersed in Charco Azul, Xichú, Guanajuato, within the Sierra Gorda-Guanajuato Biosphere Reserve, where I mention the real problems of the species to be able to survive in the face of abrupt changes in its environment, and that in the future may lead to the loss of a part of the herpetofaunal wealth of Guanajuato.
