What does John Heinz National Wildlife Refuge protect?
John Heinz National Wildlife Refuge protects a range of wetland and woodland habitats, including Pennsylvania’s largest remaining freshwater tidal marsh.
Established in 1972 through local activism, the refuge is part of the U.S. Fish and Wildlife Service’s National Wildlife Refuge System. Its habitats include freshwater tidal marsh, open water, mudflats, and woodlands. Tinicum Marsh, the state’s largest remaining freshwater tidal marsh, is a defining part of this landscape.
Those connected habitats support the refuge’s role as a place for wildlife observation. As you plan a visit, keep to designated trails and use the observation structures available from the eastern entrance.
