The results presented in this report represent a snapshot in time, highlighting the sensitive natural areas within Philadelphia and areas with a high potential for ecological restoration. The sites in the Philadelphia County Natural Heritage Inventory have been identified to help guide wise land use and county planning. The Philadelphia County Natural Heritage Inventory is a planning tool, but is not meant to be used as a substitute for environmental review, since information is constantly being updated as natural resources are both destroyed and discovered. Applicants for building permits and Planning Commissions should conduct free, online, environmental reviews to inform them of project-specific potential conflicts with sensitive natural resources. Environmental reviews can be conducted via a link on the Pennsylvania Natural Heritage Program’s website, at http://www.naturalheritage.state.pa.us/. If conflicts are noted during the environmental review process, the applicant is informed of the steps to take to minimize negative effects on iii ACKNOWLEDGEMENTS This project was funded by a grant from the William Many thanks to everyone who participated in the Penn Foundation.
