Serious population declines and loss of urodelan diversity may occur if appropriate action is not taken to mitigate against the further spread and impact of <i>Bsal</i>. We provide an overview of several potential mitigation methods, and describe their possible advantages and limitations. We conclude that long-term, context-dependent, multi-faceted approaches are needed to successfully mitigate adverse effects of <i>Bsal</i>, and that these approaches should be initiated pre-arrival of the pathogen. The establishment of <i>ex situ</i> assurance colonies, or management units, for species threatened with extinction, should be considered as soon as possible. While <i>ex situ</i> conservation and preventive measures aimed at improving biosecurity by limiting amphibian trade may be implemented quickly, major challenges that lie ahead are in designing <i>in situ</i> disease containment and mitigation post-arrival and in increasing public awareness.<b></b></p>
