Research in my lab currently encompasses applications of decision analysis and adaptive management (DAAM) to fisheries, forestry and wildlife conservation, and analyses of ecological problems in direct support of DAAM. 'Applied Conservation Biology' seems redundant. Yet, after more than 30 years on the scene in the study and theory of resources management, the potential for DAAM to resolve key scientific uncertainties at the core of effective conservation policy remains largely restricted to the academic arena and misunderstood and under-utilized by government, non-government organizations and renewable resource-based industries alike. In particular, we advocate and analyze the treatment of resource management policies as hypotheses that can and should be revised in light of management experience. Past experimental management programs, in which graduate student researchers participated, included species translocations, control of wildlife diseases and landscape-scale predator removals. Presently, research effort is devoted to retrospective analyses of natural disturbance emulation in boreal forests, with special reference to waterbirds; the effects of ecological uncertainty on the designation of species at risk; and factors affecting sustainable harvests from Great Lakes and inland freshwater fisheries.
