The DFO Great Lakes Laboratory in Burlington, Ontario, is a pivotal player in the implementation of programs on food webs, and habitat research and monitoring. Improved ecosystem management depends on understanding the impacts of management actions (fisheries, habitat, nutrient/contaminant management) in concert with other drivers of change such as climate, water levels, and species invasions. Recently, emphasis has been placed on the development of dynamic predictive nutrient, ecosystem, and habitat models to understand the relative importance of these influences. Ecosystem models are being used to assess the compatibility of multiple objectives and identify critical knowledge gaps. There is recognition that goals set separately and not as part of an ecosystem framework are unlikely to be compatible and likely to be counterproductive when implemented in the real world. As a result, there is greater understanding that fisheries management and habitat plans, traditionally developed separately, should be reconciled.
