Summary
The Alpine Newt Ichthyosaura alpestris is found through much of Europe and widely distributed in the Balkans. Sub-populations are found in parts of northern Italy and northern Spain but the species is not present in Portugal. Introduced populations have been recorded in the United Kingdom, central Spain and in New Zealand.

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.

Habitat Description
"This is a mostly aquatic species that is generally found close to water. It is widespread in both alpine and lowland habitats including wet, shaded coniferous, mixed and deciduous forests, sub-alpine meadows and pastureland. It can be found in slightly modified habitats, although it is less common in large cultivated fields. The species breeds, and larval development takes place, in stagnant waters (except large lakes) including shallow ponds, temporary pools, lakes, bogs, ditches, drinking troughs, ruts and sometimes slow-moving streams." (IUCN SSC Amphibian Specialist Group, 2022).

Justification for EICAT assessment


Ichthyosaura alpestris predate eggs of native anura species (Palomar et al. 2017). However, this impact has not been reported to cause population decline of the native species. Furthermore, it was found to host chytrid fungus at the same site the native species are affected by this fungus (Bell 2016). Therefore it is considered as minor impact.
