Reciprocal Spread of Invasive Species in Lake Michigan Coastal Habitats
Coastal areas and ports of the Great Lakes have been a major focal point of research and monitoring for AIS. The spread of AIS is generally through human-assisted means (boat trailers, bait buckets, etc.), but one often-overlooked pathway is through tributaries in the Great Lakes watershed. This continuing project is studying the distribution and invasion processes of round goby from the Great Lakes and of rusty crayfish to the Great Lakes. Monitoring and modeling this movement with various management scenarios (e.g., dam removal, stream restoration, etc.) will help better understand options for future control in light of cross-habitat invasions between inland waters and the Great Lakes. This work addresses a cross-cutting AIS-Ecosystem & Habitats priority of research aimed at deterring, eradicating and/or controlling invasive species.
