THIS IS THE PUBLIC VERSION OF AN INTERNAL DOCUMENT. The Pennsylvania section of the Delaware Water Gap National Recreation Area was studied to determine the presence of endangered, threatened, vulnerable, and rare plant species. "Pennsylvania Plants of Special Concern," a list compiled by the Western Pennsylvania Conservancy, was the basis for the investigation which included herbarium studies and determination of current status in the field. One or more populations of 14 special concern species were located. Although herbarium records for nine additional species were found, they could not be located in the field. At least one was a case of mis-identification of the original specimen. All data collected on special concern plants has become part of the state-wide Pennsylvania Natural Diversity Inventory.
