It has been introduced in other parts of Europe, outside of its native range, e.g. in the United Kingdom and in the Sierra de Guadarrama (Madrid Province, central Spain), and has also been introduced to New Zealand (Arntzen et al. 2016).
The origin of the isolated population of Alpine Newt in Guadarrama National Park, central Spain is not clear. However, an expansion of the populations has been reported, reaching as many as 57 water bodies in the time line of 15 years. A generalist predato, there are concerns of predation on native species such as the larvae of the dragonfly Aeshna juncea (listed as Vulnerable at the Spanish Invertebrate Red List) and native anuran egg masses.
