Coastal restoration efforts across the Great Lakes have expanded over recent decades, supported by increased federal and state investment in hydrologic reconnection, invasive species control, nutrient reduction, and habitat improvement. Because these projects often pursue multiple objectives, evaluating their effectiveness depends on which ecological or management goals are prioritized and monitored. This session will focus on biological responses, particularly those tied to fisheries, to assess how restoration actions translate into meaningful improvements for target species and communities. Despite numerous project level successes, basin wide evaluation of restoration effectiveness remains challenging without consistent monitoring approaches and coordinated data integration. We will open the session by outlining how monitoring can scale from the nuances of a single site to coordinated regional efforts and how those choices shape the conclusions we can draw at each scale. We will also highlight the Fish Community Objectives (FCOs) developed through the Great Lakes Fishery Commission and the Lake Committees, which provide lake specific strategic guidance on desired fish community structure and often serve as reference points for restoration planning. Together, these elements will form a shared foundation for the presentations and discussions that follow, ensuring that diverse case studies can be interpreted within a coherent framework for evaluating restoration effectiveness.
