Pittsburgh's four great parks encompass 1,700 acres with approximately 900 acres of natural or forest-like areas. These areas offer an oasis of natural lands within a city. Sustaining these areas for future generations requires intense ecological restoration today, based on proven preservation techniques, well-thought-out work plans, training of DPW work crews, and dedication from volunteers. 

The following highlights some ecological restoration work undertaken by PPC:
Snyder's Point in Riverview once again provides a broad, scenic view of the Ohio River and is drawing native birds back to the trail-head. For years, non-native, invasive plants, including porcelain berry and bittersweet vines, encroached on the area, making it inhospitable to park users. But PPC has been removing these invasive plants and reestablishing native flora to the area.
