Environmental Review List

The Environmental Review list includes threatened and endangered species, special concern species, and rare and significant ecological features, which are screened for in Conservation Explorer. The species and resources in our list have been categorized to be consistent with definitions in the Department of Environmental Protection’s (DEP) Pennsylvania Natural Diversity Inventory (PNDI) Policy. Through the PNDI review process, each agency or commission provides conservation or enhancement recommendations for the species or feature under their jurisdiction to landowners, developers, and planners. As part of the permitting process, the DEP requires permit applicants to screen their land use projects for potential impacts to threatened or endangered species using the Conservation Explorer. Read more about DEP’s PNDI Policy and rank and status definitions for further information.

A complete list of all other species and ecological features surveyed and tracked by PNHP, in addition to Environmental Review species is available on our Species and Natural Features List webpage.
