The Pennsylvania Natural Heritage Program (PNHP) inventories and maintains a list of ecologically significant species and communities.
This list represents the most up-to-date, accurate scientific information available and reflects current nomenclature.
The decisions regarding rank and status are made by a state-recognized panel of experts of the PA Biological Society.
The PNHP list of species is the basis for Environmental Review, or the Pennsylvania Natural Diversity Inventory (PNDI).

PNHP is a partnership between The Department of Conservation and Natural Resources,
the Western Pennsylvania Conservancy, the Pennsylvania Game Commission,
and the Pennsylvania Fish and Boat Commission.
