Location and Contact Information
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.
With deep respect, we acknowledge John Heinz National Wildlife Refuge at Tinicum as the homeland of the Unami-speaking Lenni Lenape of the Turtle Clan, who continue to live here in Lenapehokink, their traditional homeland, and in the diaspora. The Unami, or People Down River, are one of three dialect clans of the Lenni Lenape. Sometimes translated to the “Original People” or “Ancient Ones”, Lenni Lenape were regarded by some as “The Grandfathers” of the Algonquian family tree for their peaceful mediation. We are thankful they have been the caretakers of the land, waters, and wildlife here for thousands of years and continue to learn about their complex history and rich cultures. Please join us in celebrating their history and ongoing presence by doing the same.
Xeli Onkuntuwakan ok Wanishi wemi,
(many blessings and much thanks in Unami dialect of Lenape)
