Dale D. Humburg
Chief Scientist
M.S. Michigan State University
B.S. Iowa State University

Mr. Humburg's waterfowl education began with his dad in a duck boat in 1955.  More formal exposure to wildlife research began with the Iowa Conservation Commission as a seasonal employee (1969-1976) where he worked on red fox telemetry, pheasant nesting, duck banding, nesting studies, duck harvest data analysis, and early Canada goose restoration.  His professional career continued as an upland research biologist during 1976-1977 in Iowa.  The majority of his professional career was as a wetland and waterfowl research biologist with the Missouri Department of Conservation (MDC - 1977-2002) and more recently served as the division chief for the MDC's Resource Science Division (2002-2007).  He retired after 30 years with MDC to begin another career in September 2007 as DU’s Chief Biologist.  Experience in wetland and waterfowl research has involved semi-permanent marsh management, invertebrate dynamics, willow wetlands, Canada goose wintering ecology, evaluation of waterfowl hunting programs, surveys of waterfowl hunters, and a number of studies following the 1993 flood on the Missouri River.  Recent emphasis has been on employing adaptive management concepts as a framework for more explicit management and policy decisions.  Mr. Humburg is a wetland owner and manager, and 50 years later, is passing on lessons learned in the duck boat to his grandsons.
