No project has successfully managed the impact of introduced chytrid fungus on a amphibian population in the wild. Our project targets a Critically Endangered amphibian population, that has previously been decimated by the chytrid fungus, and asks 'can environmental manipulation prove an effective method of enabling the mountain chicken frog to survive in the wild in the face of this disease?'. If successful our methods could be used to manage populations threatened by chytrid fungus globally.
