'''John Heinz National Wildlife Refuge at Tinicum''' is a 1,200-acre urban wildlife refuge protecting the largest remaining '''freshwater tidal marsh''' in Pennsylvania. Located at Philadelphia's southwestern edge near the airport, the refuge provides critical habitat for over 300 bird species and offers city residents access to wild wetland landscapes.<ref name="heinz">{{cite web |url=https://www.fws.gov/refuge/john-heinz-tinicum |title=John Heinz National Wildlife Refuge |publisher=U.S. Fish and Wildlife Service |access-date=December 30, 2025}}</ref>

The refuge is one of America's first urban wildlife refuges and demonstrates how significant natural areas can survive even in heavily developed metropolitan areas.

== History ==

=== Tinicum Marsh ===

The '''Tinicum Marsh''' once covered more than 5,700 acres along the Delaware River. For centuries, the marsh provided food and resources for Native Americans and early European settlers.

Industrial development, airport construction, and urban expansion reduced the marsh to a fraction of its original size by the mid-20th century. Citizens organized to protect what remained.
