Rapid assessment indicates context-dependent mitigation for amphibian disease risk

July 6, 2021

Batrachochytrium salamandrivorans (Bsal) is a fungal pathogen that can cause the emerging infectious disease Bsal chytridiomycosis in some amphibians and is currently causing dramatic declines in European urodeles. To date, Bsal has not been detected in North America but has the potential to cause severe declines in naïve hosts if introduced. Therefore, it is critical that wildlife managers are prepared with effective management actions to combat the fungus. Research has been initiated to identify strategies; however, managers need guidance to prepare for an outbreak until results are available. We conducted a workshop at the Joint Meeting of The Wildlife Society and American Fisheries Society on 30 September 2019 with participants of a Bsal symposium. Our goals were to describe the expected effects of 11 management actions that could be implemented for Bsal in salamander communities in the northwestern, northeastern, and southeastern United States. Participants expected a variety of proposed management actions to decrease pathogen transmission and increase host survival, but also that the selection of a management action may depend on the specific membership of the amphibian community. Collectively, our assessment will help refine research and modeling priorities in an effort to mitigate the risk of Bsal to native U.S. amphibians.
