    The Pennsylvania Natural Heritage Program (PNHP) inventories and maintains a list of all plant and wildlife species, plant communities, and geologic features in the Commonwealth of Pennsylvania for which there is conservation concern. This list includes current and proposed vulnerable, rare, threatened, endangered, and extirpated species, as well as species of interest with unique or specific habitat needs or declining populations. It represents the most up-to-date, accurate, scientific information available and reflects current species terminology. The list includes all species and communities inventoried by PNHP and contains species that are not considered in environmental review.
