The Refuge Ecosystem
At the heart of John Heinz National Wildlife Refuge is the largest remaining freshwater tidal marsh in Pennsylvania. This rare ecosystem—where freshwater from Darby Creek meets the tidal influence of the Delaware River—creates a dynamic environment that changes with the tides.
The marsh acts as:
- A natural filter for water entering the Delaware River
- Critical habitat for migratory birds
- Spawning grounds for fish
- Natural flood control for surrounding communities
- Carbon sink to help mitigate climate change
Since the establishment of the refuge in 1972, extensive restoration efforts have reclaimed wetlands and improved habitat quality. Ongoing work addresses invasive species challenges while enhancing native plant communities that support wildlife.
