The brook newts come from Barcelona Zoo, the fauna centres of Torreferrussa and Pont de Suert operated by the Government of Catalonia, the Calafell Environmental Education and Research Centre (CREAC) and Chester Zoo, all with their own breeding and growth programmes for the larvae of this amphibian. The initiative is part of the European project Life Tritó Montseny.

Besides the Montseny brook newt, the Zoo is involved in reintroduction projects for the Spanish pond turtle (Mauremys leprosa), Hermann’s tortoise (Testudo hermanni) the Spanish toothcarp (Aphanius Iberus), the Majorcan midwife toad (Alytes muletensis), the European polecat (Mustela putorius), the Northern bald iris (Geronticus eremita) and others.
