While agriculture affects many wildlife species, this study looks at pheasants for two reasons. First, it is a very popular game bird. Data from the 1991 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation (FHWAR) indicate that the pheasant is the most popular upland game bird throughout the Midwest. Second, pheasants are sensitive to changes in uses of agricultural lands. The continued specialization in agriculture and increased use of insecticides and herbicides have cost pheasants cover and food sources, thereby reducing nesting success and chick survival (Basore, Best, and Wooley, 1987; Hill, 1976; Jahn, 1988; Messick and others, 1974; Minn. Dept of Natural Resources, 1985; Warner, 1979 and 1984; Warner and others, 1984). Thus, pheasant populations have trended downward. For example, pheasant populations in South Dakota fell from an estimated 16 million in the mid-1940s to less than 2 million by 1986 (S.D. Dept. of Game, Fish, and Parks, 1988). This study includes those States with the historically most suitable environment for pheasants, which are the Lake States (Wisconsin, Michigan, and Minnesota), the Corn Belt States (Iowa, Illinois, Ohio, Missouri, and Indiana), the Northern Plains States (the Dakotas, Nebraska, and Kansas), and Montana.
