Headquarters for the Control Methods Research Laboratory moves from Albuquerque, NM, to Denver, CO. Investigations of the food habits of wildlife and the diseases, particularly avian botulism, that affect wildlife are initiated.
The USDA Food Habits Laboratory is established in Denver, CO, to study the food habits and economic impact of predators, other mammals, and birds in the Western United States.
USDA's Bureau of Biological Survey and Bureau of Fisheries merge to form Fish and Wildlife Service (FWS) within United States Department of the Interior (USDI). Control Methods Research and Food Habits Laboratories combined to form Denver Wildlife Research Laboratory under the new FWS.
Congress authorizes reorganization of FWS into Bureau of Commercial Fisheries and Bureau of Sport Fisheries and Wildlife. As a result, Denver Wildlife Research Laboratory expands focus to include study of relationships between wildlife populations and their habitats on public lands and effects of grazing, timber management, and other land uses.
Denver Wildlife Research Laboratory renamed Denver Wildlife Research Center (DWRC). Congress charges DWRC with added responsibilities, including establishing Pesticide-Wildlife Ecology Program to study effects of pesticides on wildlife.
DWRC takes the lead in a long-term international research program in cooperation with the United States Department of State's Agency for International Development aimed at discovering, developing, and applying new and better methods to protect world food crops from ravages of "rats, bats, and noxious birds."
DWRC expands research program to include new investigations on wildlife ecology on public lands and wildlife damage.
