Located along Florida's St. Johns River about 25 miles west of the city of Daytona Beach in Volusia and Lake Counties, Lake Woodruff National Wildlife Refuge (NWR) was established for migratory waterfowl and wading birds (Figure 1). The refuge is part of a 70-mile-long wildlife corridor of ecologically sensitive lands along the St. Johns River, stretching from the Wekiva River to Lake George. The 21,574-acre refuge supports a diversity of wildlife and plant species, including a variety of waterfowl, shorebirds, and neotropical migratory birds, as well as numerous Federal- or State-listed species through a mix of freshwater marshes, rivers, impounded wetlands, and upland shrublands and forests. The refuge includes two major water bodies, which are part of the St. Johns River system: Lake Woodruff and Lake Dexter.
