Of the approximately 2,000 species native to Pennsylvania, the Preserve is home to nearly 800 of them. More than 80 of these species are rare, threatened or endangered native plants designated as Plants of Special Concern in Pennsylvania. A deer exclosure fence surrounds and protects 100 of our 134 acres. Over two and a half miles of picturesque trails offer some of the best hiking in all of Bucks County. You’re invited to learn more about our unique plant collection and the wealth of birds, butterflies, and other wildlife that it supports. Educational programs run year- round. Take our virtual tour of seasonal highlights, take advantage of our online native plant resources, and plan a visit!
