Abstract

Red swamp crayfish are one of the most widespread invasive species worldwide, including the midwestern US. As such, many natural resource agencies throughout the Great Lakes Basin have been active with implementing measures to prevent the introduction and spread of red swamp crayfish. In Michigan, for example, it is illegal to possess red swamp crayfish live regardless of the purpose. Despite taking preventive measures, red swamp crayfish were detected and infestations were confirmed in July 2017 in multiple locations throughout the Lower Peninsula of Michigan. The response efforts, led by the MDNR and Michigan State University, are multifaceted and collaborative. Together, we crafted a response plan that will: 1) Implement and evaluate an early detection monitoring strategy in high-risk areas; 2) Implement and evaluate control measures;  3) Determine the distribution of red swamp crayfish in Michigan; 4) Determine the source and relatedness of red swamp crayfish infestations;  5) Collect baseline biological and physical information. Response actions have benefited from great collaboration, but have not always been seamless. We describe lessons learned that can be applied to future responses for red swamp crayfish in Michigan, but also that can be applied to response activities for other invasive species.
