14" Methods to mitigate the impacts of emerging infectious diseases affecting wildlife are 15" urgently needed to combat loss of biodiversity. However, the successful mitigation of wildlife 16" pathogens in situ has rarely occurred. Indeed, most strategies for combating wildlife diseases 17" remain theoretical, despite the wealth of information available for combating infections in 18" livestock and crops. Here we report the outcome of a five year effort to eliminate infection 19" with Batrachochytrium dendrobatidis affecting an island system with a single amphibian 20" host. Our initial efforts to eliminate infection in the larval reservoir using a direct application 21" of an antifungal were successful ex situ but infection returned to previous levels when 22" tadpoles with cleared infections were returned to their natal sites. We subsequently combined 23" antifungal treatment of tadpoles with environmental chemical disinfection. Infection at four 24" of the five pools where infection had previously been recorded was eradicated, and remained 25" so for two years post-application. 26"
