Identifying an Understudied Interface: Preliminary Evaluation of the Use of Retention Ponds on Commercial Poultry Farms by Wild Waterfowl

Figure 4

The impact of distance to nearest road and pond size on the number of waterfowl observed utilizing retention ponds associated with commercial poultry farms. Species are broken into three groups: dabbling ducks (blue-winged teal, gadwall, mallard, northern pintail, northern shoveler), diving ducks (bufflehead, hooded merganser, and ruddy duck), and other waterfowl (Canada goose and wood duck). All data supporting this figure are available from Sullivan et al. [36].
