John Heinz National Wildlife Refuge

Celebrated as America’s First Urban Refuge, John Heinz National Wildlife Refuge at Tinicum was established in 1972. The refuge is a treasured green space nestled within the city of Philadelphia, teeming with a rich diversity of fish, wildlife, and plants native to the Delaware Estuary. The refuge supports a diversity of habitats, including freshwater tidal marsh, open waters, mudflats, and woodlands that the hundreds of species call home.
