Factors contributing to increased waterfowl use were larger local mallard (Anas platyrhynchos) and Canada goose (Branta canadensis) populations, more baited sanctuaries, increase in quantity of waterfowl food plant species as a result of higher lake levels, and the establishment of a National Wildlife Area closed to hunting. Factors that reduced waterfowl use included habitat destruction caused by agricultural drainage; marina developments on wetlands, with resulting increased boat traffic disturbing waterfowl; increased public hunting on areas that had previously been hunted at a low intensity; and population declines in species such as American black ducks (Anas rubripes) and ruddy ducks (Oxyura jamaicensis)
