Water Management Upgrades to Improve Wildlife Habitat

During this time, heavy equipment will be working along the Wetland Loop between the trailhead and the Observation tower (red shaded section of map), so this area is closed. In cooperation with our partners from Ducks Unlimited, the Refuge is installing a pump system to better manage water levels.

Visitors should not enter the closed areas during this work period. Any visitor on closed trails will be considered trespassing and may be ticketed. Additionally, the Turkey Foot Trail remains closed for restoration (See map). All other trails are open and the Big Boardwalk is accessible through Warbler Woods trail, but you may not exit the boardwalk near or on the ramp at the Darby Creek side. Thank you for your patience as we improve wetland habitat!


Turkey Foot Trail Restoration Project

Please note that Turkey Foot Trail, as indicated by the map, will be closed to all access while a restoration project is taking place. The refuge is working in coordination and partnership with the State of Pennsylvania, Friends of Heinz refuge, Princeton Hydro, and Enviroscapes to restore the function of the tidal marsh in the Turkey Foot area.  This project will improve habitat for native turtles, wading birds, shorebirds, and fish species.  Please do not use this area during the closure period. We appreciate your patience while this restoration project is completed. Please reach out to if you have any questions.



John Heinz National Wildlife Refuge at Tinicum is part of the Urban Wildlife Conservation Program, whose main goal is to engage urban communities as partners in wildlife conservation. The Urban Standards of Excellence is the framework for this collaboration and guides the refuge in our work both on refuge lands and in the neighboring communities.
