Summary Data Number of Taxa: 12 Species, in 12 Genera, 9 Families, and 5 Orders. Description No formal investigations of the mammals of the GNA have been conducted. And, until 2016, no system was in place for tracking annual observations of mammal species. Hence, this checklist represents a somewhat haphazard collection of data. GNA staff observations from 2016 onwards represent a significant portion of the data. These observations have been augmented by data from various reports and from photos from the GNA that were posted to Facebook. Status/Threats IUCN Status: Data are from the IUCN Red List of Threatened Species (IUCN 2020). The GNA checklist was compared with the Pennsylvania Natural Heritage Environmental Review List (PNHP 2020). None of the eleven mammal species listed on the environmental review list are known to occur in the GNA. The checklist was also compared with the Pennsylvania Game Commission's Wildlife Action Plan (PGC 2020). None of the nineteen mammals listed in the Wildlife Action Plan are known for the GNA. And, the checklist was compared with species listed in the Chester County Natural Heritage Inventory (PNHP 2015). None of the mammal species known for the GNA were listed as being of special concern in Chester County.
