Global amphibian decline and extinction has been associated with the spread of the pathogenic chytrid fungus (Batrachochytrium dendrobatidis,Bd). Despite extensive research, there have been no examples of effective management abating the ongoing impact of this pathogen in the wild. The endangered alpine tree frog (Litoria verreauxii alpina) has been extirpated from 80% of its former range because of Bd. We directly tested whether source population or host site influenced the efficacy of a reintroduction of L.v.alpina. We captive reared and released 1241 individuals from three different populations, two with a history of Bd exposure and one that was Bd-naïve, into two sites where they had his..
