John Heinz National Wildlife Refuge at Tinicum spans 1,200 acres and protects Pennsylvania's largest remaining freshwater tidal marsh. Tucked along Philadelphia's southwestern edge near the airport, it's home to over 300 bird species and gives city residents genuine access to wild wetland ecosystems.[1]
This refuge proves something important: major natural areas can persist even in heavily developed cities.
It was America's first urban wildlife refuge.
History
Tinicum Marsh
Back when William Penn arrived, the Tinicum Marsh covered more than 5,700 acres along the Delaware River. For centuries, Native Americans and early European settlers drew food and resources from its waters and plants.
Everything changed with industrialization. Airport construction and urban expansion chipped away at the marsh. By mid-twentieth century, it had shrunk to a tiny fraction of what it once was. But locals fought to save what remained.
Refuge Establishment
Congress established the refuge in 1972 as the nation's first urban wildlife refuge. A decade later, in 1991, it was renamed to honor Senator John Heinz of Pennsylvania. He'd been a fierce environmental advocate until his death in a plane crash that same year.
