On May 12, 2017, Canada took an official stance to protect amphibian diversity in North America by amending their Wild Animal and Plant Trade Regulations to restrict all salamander imports for one year. This was done in an effort to prevent the spread of Batrachochytrium salamandrivorans (Bsal), a deadly fungal pathogen that, if introduced, could decimate native amphibian populations and threaten ecosystem health. This proactive approach follows recommendations from AmphibiaWeb researchers who identified high Bsal-risk areas in North America by integrating Bsal habitat suitability, host availability, and salamander trade data (Yap et al. 2015). Other scientists have called for preventive measures as well, including the Canadian Wildlife Health Cooperative (Stephen et al. 2015) and the United States Geological Survey (Richgels et al. 2016). The one-year moratorium buys time for researchers to learn more about Bsal and develop a long-term strategy to defend against disease spread.
