Figure 3

The impact of vegetation immediately surrounding retention ponds on commercial poultry farms on the number of waterfowl observed utilizing the ponds. Species are identified via the standard four-letter alpha codes (BWTE, blue-winged teal; GADW, gadwall; MALL, mallard; NOPI, northern pintail; NSHO, northern shoveler; BUFF, bufflehead; HOME, hooded merganser; RUDU, ruddy duck; CANG, Canada goose; and WODU, wood duck). All data supporting this figure are available from Sullivan et al. [36].
