Research

Research encompassed applications of decision analysis and adaptive management (DAAM) to fisheries, forestry and wildlife conservation, and analyses of ecological problems in direct support of DAAM. In particular, we advocated for, and studied how to, treat resource management policies as hypotheses that could and should be revised in light of management experience in diverse applications from species translocations and control of wildlife diseases to factors affecting sustainable harvests from Great Lakes and inland freshwater fisheries.
