Mitigating Batrachochytrium salamandrivorans in Europe


Abstract

The infectious chytrid fungus <jats:italic>Batrachochytrium salamandrivorans</jats:italic> (<jats:italic>Bsal</jats:italic>) has been responsible for severe population declines of salamander populations in Europe. 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 <jats:italic>Bsal</jats:italic>. 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 <jats:italic>Bsal</jats:italic>, and that these approaches should be initiated pre-arrival of the pathogen. The establishment of ex situ assurance colonies, or management units, for species threatened with extinction, should be considered as soon as possible. While ex situ conservation and preventive measures aimed at improving biosecurity by limiting amphibian trade may be implemented quickly, major challenges that lie ahead are in designing in situ disease containment and mitigation post-arrival and in increasing public awareness.
