Nature & Science

Valley Forge National Historical Park encompasses an area of great historical significance, as well as a substantial area of native biodiversity. The 3,500-acre park is one of the few, large, contiguous, protected areas in southeastern Pennsylvania that has a variety of habitat types including a river, numerous streams and forested wetlands, eastern deciduous forest, and tall-grass meadows. The park is surrounded by residential, commercial and industrial developments of Montgomery and Chester Counties on all sides, thus it is an oasis for native wildlife.
