The Moraine Preservation Fund (MPF) is a non-profit, volunteer organization that supports Moraine State Park. MPF has helped to develop important wildlife restoration projects like Project BATitat, the Osprey and Barn Owl Reintroduction Programs, along with the creation of a Native Plant & Butterly Trail near the center. MPF volunteers also participate in wildlife education classes at schools and for other interested groups to teach the public about barn owls. MPF operates Preston's Pearl and The Owlet Gift Shop and Nature Center located at McDanel's Boat Launch, located just off the North Shore park exit on Rt. 422 in Portersville.
