| Riassunto: | High mountain stream’s mole salamanders (Ambystoma) are vulnerable species owing to their restricted distribution, which is limited to little streams located at high mountains in the Trans-Mexican Volcanic Belt. Besides, those species are formed by small and isolated populations increasing their vulnerability. Potential threats to Ambystoma rivulare, A. altamirani, and A. leorae, were reviewed, based on SEMARNAT criteria, and the Environmental Vulnerability Score (EVS) proposed by Wilson and McCranie (2003). If conservation status should be changed to a higher level of protection is discussed.
