The Pennsylvania Natural Heritage Program regularly updates species occurrences in the Conservation Explorer. These updates ensure the Explorer is using the most current data available for conservation information. Some reasons for changes include:
- A species being newly listed by an agency or newly proposed for listing
- An occurrence of a currently-listed species that previously did not have any confirmed populations
- A species being newly delisted, no longer proposed for listing, or proposed for delisting by an agency
The tables below provide a summary of changes as of October 30, 2023. Additional information on species status definitions can be found here. Please email RA-HeritageGIS@pa.gov if you have further questions.
