Center – purchased of land within the park boundary with plans to construct a conference center, hotel, retail, campground and museum on the site. The National Parks Conservation Association and local citizens sued Lower Providence Township over the zoning change that enabled this proposal. The two parties agreed to allow NPS to keep the land, and in exchange, the American Revolution Center was given property in Philadelphia, where it built the Museum of the American Revolution. An overpopulation of white-tailed deer has resulted in "changes in the species composition, abundance, and distribution of native plant communities and associated wildlife" in the park. In 2008, the National Park Service released a draft deer management plan and environmental impact statement for public review. The intent of the controversial plan was to "support long-term protection, preservation, and restoration of native vegetation and other natural resources within the park." Hunting is expressly prohibited by the legislation that created the park, and action by Congress would be required before it could be sanctioned. Since the plan was put into place, natural habitats have been restored and vegetation not seen in the park for decades has begun to return. The park includes the site of the Ehret Magnesia Company, a former manufacturer of asbestos-insulated pipes. Pre-existing dolomite quarries were subsequently backfilled with asbestos-containing slurry waste materials. Those areas of the park are closed to visitors, and an effort is underway at permanent remediation.
